| Foreword
This is a report on
the New Chance Observational Study an in-depth examination
of parenting behavior and its relationship to childrens
development in a subset of the families participating in the
New Chance Demonstration.
New Chance was a national
research and demonstration project that provided comprehensive
education, training, and other services intended to improve
the prospects and well-being of low-income mothers and their
children. The programs eligibility criteria were designed
to assure that the research sample represented families central
to the welfare reform debates of the past 10 years: families
headed by young mothers who had their first child as teenagers,
were high school dropouts, and were receiving Aid to Families
with Dependent Children. (AFDC was the main cash welfare program
until the 1996 federal welfare legislation replaced it with
Temporary Assistance for Needy Families, or TANF.)
One of New Chances
distinguishing features was its explicit two-generational
focus on both mothers and children. Many of its services were
meant to help the mothers prepare for, get, and hold onto
jobs so that they could become economically self-sufficient
and leave welfare. In designing the demonstration, MDRC believed
that such changes, if they occurred, would potentially improve
developmental outcomes for children. But the aim was to shape
the childrens development more directly. Therefore,
the demonstration included parenting education, access to
pediatric health services, and an attempt to develop and encourage
the use of good-quality child care.
The original research
plan for evaluating the New Chance Program recognized the
importance of assessing its two-generational nature. Thus,
it included several measures of parenting behavior and participation
by the mother in the child-related components of New Chance
(e.g., parenting education), along with various measures of
the childrens development. Sources for the latter included
surveys of parents, reports from teachers (for children in
the research sample who were in formal child care or school
settings), and a general measure of school readiness.
While the initial design
of the New Chance Program and its research plan went beyond
the practices typical of large-scale field studies of this
type, they created the opportunity to push even further. Thus,
MDRC formed an interdisciplinary "observational studies
team" that designed and implemented the New Chance Observational
Study and a companion study embedded within the evaluation
of the Job Opportunities and Basic Skills Training (JOBS)
Program (the welfare program authorized under the legislation
that preceded the legislation establishing TANF).
Each of the observational
studies makes a new and unique contribution regarding how
best to measure parenting and child outcomes in a survey context.
This is a question important to anyone trying to understand
the effects on children of welfare reforms or similar initiatives.
Much of the existing information about how children develop
comes from the university-based laboratories of developmental
psychologists, yet social policies and programs play out in
the everyday lives of parents and children. The observational
studies transported university-based techniques into the field,
gathering data via videotape and audiotape in the participants
homes. In large part, this translation of methods and materials
succeeded, and it yielded rich information about the strengths
and limits of using regular survey interviewers to go well
beyond their typical interviewing tasks. The information on
all this methodological work is found in the second part of
this monograph.
The incorporation of
these new techniques and measures into the New Chance Demonstration
also allowed us to deepen our answers to certain questions.
For example, using the originally planned survey measures,
MDRC staff have examined questions about the effects of New
Chance on parenting, and the relationships between those effects
and child outcomes. But these analyses acknowledged the limits
of data on parenting or child development that come from parental
self-report and observations by survey interviewers. By including
the measures derived from videotapes and audiotapes of the
observational study sessions, the observational studies team
was able to more fully explore the effects of New Chance on
parenting, the relationships between program participation
and these effects, and the role of the parenting effects on
child outcomes.
Interestingly, the
New Chance program did have positive effects on parenting.
These appeared on both survey interviews and observational
measures. However, other influences such as maternal psychological
well-being, including stress and depression, combined with
the effects of parenting behavior on children. Thus, the positive
parenting differences were not sufficient to bring about effects
on child outcomes, no matter how the parenting and child outcomes
were measured.
While the observational
study data were consistent with the survey data and thus did
not change our judgments about the effects of the New Chance
Program, they were promising in other ways. The observational
data appear to have tapped a wider range of parent and child
behaviors than is possible in the survey context. For example,
the survey measures did not detect program impacts in the
area of cognitive stimulation, while the more sensitive and
qualitative observational measures did. The observational
measures also added to our ability to understand why some
children are doing better than others. Such questions and
analyses are the subject of the first part of the monograph.
Interdisciplinary and
pathbreaking, the observational study represented a collaboration
among a diverse team. The editors of the monograph, Martha
Zaslow and Carolyn Eldred, have generously described the roles
of all team members except themselves in the Acknowledgments.
Each of the editors has given an extraordinary amount of time
to this effort over the last six years, and their contributions
cannot go unnoted.
Martha Zaslow has been
involved in all aspects of this work. Together with colleagues
at Child Trends, she analyzed the interview-based measures
of parenting, examined the relationships across different
parenting measures, and conducted analyses regarding the role
of parenting and other factors in predicting child outcomes.
She also wrote or contributed to several chapters in the first
part of the monograph and reviewed all of the manuscript several
times.
Carolyn Eldred began
the effort as the project director for the New Chance surveys
at the Institute for Survey Research at Temple University.
In that role, she worked with MDRC to hone the overall study
design, thought through the myriad issues involved in conducting
and recording the observational sessions, adapted the laboratory
protocols for survey administration, trained the field staff,
and directed the data collection effort. Subsequently, as
a consultant to MDRC, she undertook the methodological reflection
and analysis in the second part of the report, wrote the chapters
on methodological issues, coauthored the chapter on study
design in the first part of the report, and reviewed the entire
monograph several times. Both editors have been "first
among equals" on this team.
The study owes a great
debt to the energy and good efforts of the mothers who invited
us into their homes, diligently worked through the tasks with
their children, and shared their thoughts in the interviews.
Above all else, the research team hopes that this work is
up to the trust shown by these families. They have been open
and generous; this monograph is dedicated to improving their
lives and the lives of others in similar circumstances.
Finally, we are grateful
to the funders of the observational study: the Foundation
for Child Development, the William T. Grant Foundation, the
Smith Richardson Foundation, and the National Institute of
Child Health and Human Development. Their commitment made
the project possible.

The New Chance Demonstration
The New Chance Observational
Study the subject of this monograph is an in-depth
examination of parenting behavior in 290 of the 2,322 families
studied in the New Chance Demonstration, a national research
and demonstration program operated between 1989 and 1992 at
16 locations in 10 states. The demonstration tested a program
model intended to improve the economic prospects and overall
well-being of low-income young mothers (aged 16 to 22) and
their children through a comprehensive and intensive set of
services. It was developed by the Manpower Demonstration Research
Corporation (MDRC) and supported by a broad consortium of
public and private funders.
New Chance was directed
at families central to the welfare reform debates that culminated
in the Personal Responsibility and Work Opportunity Reconciliation
Act of 1996 families headed by young mothers who gave
birth during their teenage years and were receiving Aid to
Families with Dependent Children (AFDC, the main cash welfare
program).1 More specifically,
New Chance focused on those who were especially disadvantaged
because they were high school dropouts; as a group, they and
their children are at high risk of long-term welfare receipt
and economic hardship.
The New Chance Program
sought to help the young mothers (who, for the most part,
volunteered for the program) to acquire educational and vocational
credentials and skills so that they could find and keep jobs
offering opportunities for advancement and reduce, and eventually
eliminate, their use of welfare. It also sought to motivate
and assist participants to postpone additional childbearing
and to become better parents. Because New Chance focused on
young children as well as their mothers, it sought to further
the cognitive, social, and emotional development as well as
the health of participants children. Child care was
provided at no cost to the parents, on site in most places,
and the program facilitated access to health services for
both mothers and children. The program was intended to be
intensive (four to five days a week for up to 18 months),
though in practice attendance was of much shorter term and
often irregular.2
II.
Parenting Behavior and the Two-Generational Character of New
Chance
New Chance was one
of only a few interventions for families in poverty that took
a two-generational approach, seeking to improve the outcomes
for both the young mothers, who faced multiple difficult life
circumstances, and their children. For this reason, parenting
behavior took on particular importance. If the New Chance
Program improved the quality of the mother-child relationship,
it would signify improved functioning in an important area
of the mothers lives. It would also have the potential
of diminishing risk and improving developmental outcomes for
the children. Research shows that the children of young single
mothers in poverty begin to show higher levels of behavior
problems as early as the preschool years. Later in development,
they show difficulties in school progress and achievement.
New Chance sought to
enhance parenting behavior most directly through its parenting
classes, which provided information on childrens developmental
stages, activities and materials to enhance childrens
cognitive development, and developmentally appropriate strategies
for shaping child behavior. Parenting classes, which were
scheduled for about two hours a week, balanced open discussion
of issues of concern to the mothers and more formal presentation
of specific information.
Other aspects of New
Chance also held the potential for enhancing parenting behavior.
Life skills training (like parenting classes, scheduled for
about two hours a week) focused on improving the mothers
skills in communicating with significant people in their lives,
including children. Adult basic education (including preparation
for the General Educational Development, or GED, test) and
job skills training classes provided stimulation to the mothers,
which in turn could be reflected in how they talked with,
read to, and played with their children. Group and individual
counseling addressed problems emerging in the mothers
lives, including problems with children. Family planning classes
stressed the importance of providing enough time and attention
to each child in the family. The child care that the children
participated in provided a context for the young mothers to
observe care providers engaging in stimulating and supportive
interactions with children behavior they might then
imitate. Participation in the program as a whole could increase
the mothers sense of social support, which in turn could
enhance parenting behavior.
III.
The New Chance Observational Study: A Study Embedded in the
New Chance Evaluation
A. Evaluating the
New Chance Program
Central to the New
Chance Demonstration was a rigorous evaluation of the programs
effectiveness. For this purpose, 2,322 young women who applied
to New Chance were randomly assigned to either an experimental
group (who were allowed to enroll in New Chance) or a control
group (who did not have access to services provided through
New Chance, but many of whom found some alternative services
in their communities). To determine the effectiveness of the
New Chance "package" of services, compared with
these alternative services, differences in outcomes
between the two groups of women and their children (often
referred to in this kind of research as the impacts
of the program) were examined through structured survey interviews
administered approximately 18 and 42 months after each young
woman entered the research sample. The findings from the demonstration
have been presented in a series of MDRC reports concluding
with the final report, released in 1997.
B. The Purposes
of the Observational Study
Because of the importance
of parenting behavior in the context of a program focusing
on outcomes for two generations, a special study was undertaken,
using videotaped observations of mother-child interaction
among a subset of 290 families in the New Chance Demonstration.
The work of a collaborative and interdisciplinary research
team (described in the Foreword to this monograph), the observational
study was funded by grants from the Foundation for Child Development,
the William T. Grant Foundation, and the Smith Richardson
Foundation, with specific analyses focusing on methodological
issues funded by the National Institute of Child Health and
Human Development.
The observational data
were collected during a special session following the 18-month
follow-up survey for the full evaluation, on average 21 months
after each member of the observational study sample had enrolled
in the demonstration. The videotapes of mother-child interaction
were then coded under rigorous conditions in university laboratories.
The purposes of the study were to (1) describe parenting behavior
in this sample, especially the affective quality of mother-child
interaction and the aspects of interaction that are related
to the emergence of literacy in children; (2) examine in greater
depth the programs impacts on parenting behavior; (3)
explore the role of parenting behavior in shaping the outcomes
for children; and (4) assess the added value of using measures
of parenting based on direct observation in addition to the
evaluations survey interviews.
More specifically the
study asked:
- What background
characteristics of the families are most closely related
to parenting behavior for the families in the sample?
- Based on sensitive
and detailed measures of parenting used in the observational
study, did the New Chance Program have positive impacts
on parenting behavior and, if so, which program components
contributed?
- What role did parenting
behavior play in shaping the development of the children
in the sample? What was the role of such other important
influences as the mothers psychological well-being
and the familys economic resources?
The study also asked
how best to measure parenting behavior in a program evaluation
that focuses on two generations. More precisely:
- Do measures of mother-child
interaction based on direct observation substantially improve
the quality of information about parenting beyond what is
available through measures collected in the context of survey
interviews? Part II of this Executive Summary (and of the
monograph) discusses the methodological issues in more detail.
C. The Sample
The sample for the
New Chance Observational Study was chosen from the seven New
Chance sites that had the largest number of families who met
the studys criteria and could potentially participate.
Specifically, the study chose families with a "focal
child" between 30 and 60 months old, an age range considered
appropriate for the studys procedures. (The "focal
child" was the child in each family who was the focus
of the interviews and assessments in the full evaluations
impact research.) In addition, the observational study was
limited to African American and white families, rather than
also including Hispanic families, because the researchers
did not consider it possible to give full consideration to
variation in parenting behavior that might be associated with
cultural background. To study how parenting behavior related
to other important aspects of the families lives, the
sample was also limited to families who had completed the
evaluations 18-month follow-up interview. Finally,
the study was restricted to families for whom the observational
study session could be scheduled within a similar time frame
relative to random assignment no more than four months
after each mothers 18-month follow-up interview. The
eligibility criteria for this study were more restrictive
than the criteria for the overall New Chance Evaluation, and
the sites used in the observational study were not selected
randomly from all the New Chance sites. Therefore, the findings
from the observation study should not be seen as generalizing
to the full New Chance sample. The larger evaluation sample,
for example, included families with children in a broader
age range, families from additional sites, and families of
Hispanic origin.
The sites from which
the families were chosen were the Bronx, Detroit, Harlem,
Lexington (Kentucky), Philadelphia, Pittsburgh, and Portland
(Oregon). Within each of these sites, families who met the
studys eligibility criteria were contacted in the order
in which they had enrolled in the demonstration.
The goal was to conduct
observational sessions with about 300 families a sample
size large enough to detect program impacts on the observational
measures and to permit an examination of how parenting behavior
was related to the mothers education, age at first birth,
years receiving public assistance, and other important characteristics,
as well as child outcomes. Of the New Chance sample members
who met the criteria for inclusion in the observational study,
79 percent participated, yielding usable videotapes from 290
families. Approximately 84 percent were African American and
16 percent were white. Among the focal children, 148 were
boys and 142 were girls. One hundred and eighty-four
of the mothers were members of the demonstrations experimental
group and 106 were from the control group. The families in
the two groups did not differ significantly in their baseline
characteristics, so group differences found at the time of
the observational study can be attributed to the experiences
of the families subsequent to random assignment. Nor was there
evidence of systematic differences between the families identified
as eligible to participate in the observational study who
did and did not participate.
D. An Overview of
the Studys Procedures
The visit to each family
participating in the observational study (lasting, on average,
about an hour) was conducted by a two-member team a
survey interviewer, who briefly interviewed the mother and
guided her through a series of interactive tasks with her
child, and a videographer, who taped the mother and focal
child as they carried out the interactive tasks. The interviewers,
who were accustomed to conducting traditional survey interviews
and were already working on the New Chance 18-month survey,
received specialized training to follow a structured script
and to explain and administer the tasks to the mothers with
minimal interference in the mother-child interaction.
The observational session,
or extra visit carried out for the New Chance Observational
Study, started with the interviewer explaining the procedures
to the mother and obtaining her informed consent. The interviewer
then administered the first half of a brief interview with
the mother, in which she was asked to describe, in half-hour
intervals, the activities that she and her child had engaged
in during the previous weekday. Beginning the session in this
way helped the interviewer to establish rapport with the mother,
gave the videographer time to set up the equipment, and provided
further information about the mother-child relationship.
Following a script,
the interviewer then described each of the interactive tasks
to the mother and confirmed that she understood how to carry
out each task. After these initial instructions, the child
was invited to join the mother and interviewer, and the mother
was asked to guide her child through each of the interactive
tasks. The script called for the interviewer to remind the
mother briefly about each task as she presented the props
for that task. Interviewers were instructed to then let the
mother interact with her child as she chose, without interference.
The tasks, devised
by university-based researchers of childrens development,
had been used in previous studies of mother-child interaction,
including studies of low-income families. The six tasks were:
- Book reading.
The mother was asked to read and discuss a childrens
book, The Very Hungry Caterpillar (by Eric Carle),
with her child the way she would usually do so;
- Blocks. The
mother was asked to try to get her child to match the shape
of a larger block by using combinations of smaller blocks;
- Wheels. The
mother tried to get her child to name as many objects with
wheels as he or she could within the time allotted;
- Sorting.
The mother asked her child to place plastic chips of different
shapes and colors in the empty squares on a board according
to the shapes of chips glued onto the board in a row at
the top, and the colors of chips glued on in a column at
the left;
- Etch-a-Sketch.
The mother tried to get her child to use the knobs on an
Etch-a-Sketch board to draw a line tracing a maze that had
been drawn on the screen;
- Gift. The
mother was presented with a wrapped gift a kaleidoscope
to give to the child, and the mother and child then
spent a few minutes opening and playing with the gift.
Each of these tasks
had either been used by members of the research team in previous
studies or was a modification of a task used before. The tasks
were chosen because they yield forms of mother-child interaction
that predict social behavior and academic achievement in school.
The observational session
concluded with the interviewer administering the final portion
of the brief interview to the mother, which included questions
about use of child care for the focal child; the mothers
participation in educational, training, and employment activities;
and the familys residential situation. The interviewer
also completed ratings about the home environment and about
the observational session (for example, whether there had
been others in the home during the session and whether the
session had been interrupted), and the mother completed a
brief "self-administered questionnaire" with items
concerning her subjective sense of well-being, perceptions
of the focal child, and reactions to the mother-child interaction
tasks.
The initial instructions
to the mother as well as the series of mother-child interaction
tasks (but not the interview segments of the observational
session) were videotaped. The videotapes of mother-child interaction
were then coded in two independent research laboratories.
The affective quality of mother-child interaction was rated
by a team of researchers at the University of Minnesota. Ratings
of mother-child interactions related to the emergence of literacy
were made by a team of researchers at Harvard University,
based on transcriptions of verbal interactions during the
book reading and wheels tasks and on the interactive behavior
from the videotapes for these tasks.
E. Parent-Child
Data from the Full New Chance Evaluation
The families in the
New Chance Observational Study also participated in the data
collection that was part of the full New Chance Demonstration.
Thus, there is information on the families prior to their
being randomly assigned to the evaluations experimental
or control groups ("baseline data"), before any
program effects could have occurred. There are also data from
the 18- and 42-month follow-up surveys, both of which included
measures of the mothers psychological well-being; educational
attainment, employment, earnings, and welfare receipt; residential
situation; use of child care for the focal child; and fertility.
The surveys from the
full evaluation also included interview-based measures of
parenting. The analyses reported on in this monograph focus
on parenting measures from the 18-month follow-up survey,
because these were collected close in time to the observational
measures. The 18-month follow-up included three parenting
scales based on maternal report: Warmth, Control, and Parenting
Stress. The 18-month follow-up also included a measure
of the emotional support and cognitive stimulation available
to the child in the home environment, based on a combination
of questions asked of the mother and ratings completed by
the interviewer. This measure, the Home Observation for Measurement
of the Environment-Short Form (or HOME-SF), provided a total
score as well as Emotional Support, Cognitive Stimulation,
Harsh Discipline, and Physical Environment subscale scores.
Table 1 lists the parenting
measures available for the sample of the New Chance Observational
Study and the source of each measure. It is important
to note that the parenting measures included in the New Chance
Observational Study rely on several different informants (mothers,
interviewers, and coders of the observational session videotapes).
Thus, we are not confined to one data source in examining
the New Chance Programs possible impacts on parenting
behavior. Each of the measures (along with information about
its previous use and psychometric properties) is described
in detail in the monograph.
The focal childrens
development was assessed as part of the 42-month follow-up.
Direct assessments of their cognitive development were carried
out using the School Readiness Component of the Bracken Basic
Concept Scale, which assesses childrens knowledge of
such concepts as colors, letters, numbers, shapes,
counting, and making comparisons. In addition, mothers rated
their childrens behavior problems (using the Behavior
Problems Index) and positive social behaviors (using the Positive
Behavior Index) and responded to questions concerning their
childrens health. The Behavior Problems Index
provides a total score and subscale scores for behaviors that
reflect antisocial, anxious/depressed, headstrong, hyperactive,
dependent, and peer conflict/withdrawal behaviors. The Positive
Behavior Index provides a total score and subscale scores
for compliance, social competence, and autonomy.
For those children
already in a formal child care situation or school setting,
teachers were asked to complete a survey, in which they rated
childrens academic and behavioral adjustment to school.
They also completed the Behavior Problems Index and the Positive
Behavior Index.
IV.
The Findings in Brief
- Mothers in the
New Chance Observational Study sample were at particularly
high risk in terms of parenting behavior.
Some of the parenting
measures used in the New Chance Observational Study had been
used in other studies of high-risk families. On these measures,
New Chance mothers had less positive scores than mothers in
the other high-risk samples. When reading to their
children, New Chance mothers showed lower frequencies of "Nonimmediate
Utterances," that is, speech that extends beyond the
information in the book (the specific words in the text and
the pictures shown) to make connections with other experiences
and information. Previous research shows Nonimmediate
Utterances to be important in laying the groundwork for later
literacy in children. Mothers in the New Chance Observational
Study also expressed hostility to their children more often
than the mothers in another high-risk sample. Harsh mother-child
interaction is important to development, predicting less positive
adjustment in children.
- Despite their
similar economic circumstances and backgrounds, the mothers
in the New Chance Observational Study showed variation in
their parenting behaviors, and parenting behaviors were
meaningfully related to the mothers background characteristics.
Among mothers in the
New Chance Observational Study sample, more emotionally supportive
and cognitively stimulating parenting behaviors were associated
with higher maternal literacy, more educational attainment,
better maternal psychological well-being, greater social support,
and the childs having participated in child care.

- The New Chance
Program was able to bring about positive changes in parenting
behavior, even in a population burdened by economic stress
and other serious difficulties.
Positive program impacts,
although modest in magnitude, were seen in both the affective
quality of mother-child interaction and the cognitive stimulation
that the mothers provided. In terms of the affective quality
of interaction, mothers in the experimental group had
significantly lower scores on the Harsh Treatment measure,
higher scores on the HOME-SF Emotional Support subscale, and
higher scores on the Maternal Warmth scale. In terms of
cognitive stimulation, mothers in the experimental group
received higher scores on the Book Reading Quality measure.
Positive program impacts were also found on the HOME-SF
total score and on time use measures devoted to parenting
(both Overall Parenting Time and Parenting Chore Time
time spent engaged in such chores as feeding and bathing children).
- Positive program
impacts were found across parenting measures obtained in
several different ways and from different informants.
Differences were found
for parenting measures based on direct observation of mother-child
interaction ( Harsh Treatment and Book Reading Quality), measures
based entirely on maternal report (Warmth, Overall Parenting
Time, and Parenting Chore Time), and measures that rely on
a combination of maternal report and interviewer ratings (the
HOME-SF total score and Emotional Support subscale).
- Parenting behavior
was an important predictor of specific child outcomes in
this sample, as were variables reflecting maternal psychological
well-being and the families larger social context.
Positive implications
of supportive and stimulating parenting behavior combined
with the negative implications of maternal psychological distress
and stress in the larger social context to shape the developmental
outcomes of children in this sample.
- Modest improvements
in parenting behavior, in this context, did not suffice
to bring about positive program impacts on child outcomes.
Given the high levels
of maternal psychological distress and stress in this sample,
bringing about positive impacts on child outcomes might have
required (1) a more intensive "dosage" of parenting
education classes or other program components that enhance
parenting behavior, (2) sufficiently intense program components
directly focusing on the mothers psychological well-being
and living situations, and/or (3) high-quality child care,
with children participating over a sustained period of time.
- Observational
measures add to the understanding of parenting behavior
within this sample in multiple ways.
Observational measures
increase ones confidence in findings on program impacts
because the coding is carried out in an extremely rigorous
way. They also tap into certain behaviors that are important
to childrens development, but that mothers may not be
able to report on (such as their use of Nonimmediate Utterances
during book reading). Also, the findings indicate that observational
measures have advantages over interview-based measures for
predicting variation in childrens scores on specific
child outcomes. For example, consideration of the observational
measures of mother-child interaction significantly improved
prediction of the Behavior Problems Index (as reported on
by the mother) even when parenting measures based on interviews
had already been taken into account. In short, observational
measures provide valuable information that can enrich the
evaluation of programs such as New Chance.
V.
Parenting Behavior in This Sample Relative to Other Samples
The observational study
interaction tasks, and the coding of behavior from those tasks,
grew out of previous research in the laboratories of Catherine
Snow, Jeanne De Temple, and their colleagues at Harvard University,
and Byron Egeland, Nancy Weinfield, John Ogawa, and their
colleagues at the University of Minnesota. Since the measures
have been refined and improved over time, it is generally
not possible to compare directly the findings from the New
Chance Observational Study with those from previous studies.
For a few specific measures, however, modifications in rating
scales have not occurred. When we look at findings for those
measures that can be compared across studies, we see that
New Chance Observational Study families are at particularly
high risk in terms of parenting behavior.
One key measure of
mother-child interaction related to the development of childrens
literacy is the proportion of maternal talk during the book
reading task that involves Nonimmediate Utterances, that is,
connecting the story and pictures to other events, people,
and objects. Such talk also involves making predictions, asking
for inferences, and providing explanations. Previous research
using this measure in the Home-School Study of Language and
Literacy Development, a longitudinal study of low-income mothers
and their children, found maternal use of Nonimmediate Utterances
to be related to important child outcomes in the early years
of elementary school, especially the childrens use of
language and their literacy skills.
Nonimmediate Utterances
in the context of a book reading task constituted 10.5 percent
of mothers utterances in the Home-School Study of Language
and Literacy Development, but only 3.5 percent of talk among
New Chance Observational Study mothers. The researchers note
that "Since we have found that maternal use of Nonimmediate
Talk relates to later child outcomes . . . the very low proportion
of Nonimmediate Talk produced by the New Chance mothers is
troubling."
The ratings scales
of the affective quality of mother-child interaction used
in the New Chance Observational Study are adaptations of scales
developed in the Minnesota Mother-Child Project, a longitudinal
study of high-risk mothers and children. The Hostility rating
scale has not been substantially modified for the present
study, and results can be compared across studies. Ratings
of 5 or above indicate that a mother is more hostile than
not in interacting with her child during the course of the
mother-child tasks. Seven percent of the New Chance Observational
Study sample scored 5 or above compared with 2.7 percent on
the Minnesota Mother-Child Project sample.
These findings suggest
that the New Chance Observational Study sample is at greater
risk in terms of parenting behavior than the previously studied
high-risk samples, underscoring the importance of attempting
to enhance parenting behavior in the population of young single
mothers in poverty.
VI.
Variation in Parenting Behavior in Light of Maternal and Family
Characteristics
Family characteristics
were significantly linked with parenting behaviors, and associations
were more consistent with 18-month than baseline variables,
suggesting that the more current family context is of greater
importance to parenting behaviors. These characteristics included
social support; measures of the mothers psychological
well-being, residence pattern, maternal education, and literacy;
and the childs participation in child care during the
initial 18-month follow-up period.
For example, mothers
who reported more sources of social support at the time of
the 18-month follow-up interview had more positive relations
with their children in terms of the observed affective quality
of mother-child interaction, the observed literacy-related
aspects of interaction, and the harshness of discipline as
measured by the HOME-SF. Mothers at high risk for depression
at the 18-month follow-up had lower scores on all but one
of the HOME-SF subscales, had lower observed Book Reading
Quality scores, reported more parenting stress, and described
themselves as using more controlling disciplinary practices.
VII.
Program Impacts on Parenting Behavior
Significant positive
program impacts on parenting behavior were found on a range
of parenting measures:
- Measures based on
direct observation of mother-child interaction:
Harsh Treatment
Book Reading Quality
- Measures based on
maternal report alone:
Maternal Warmth
Overall Parenting Time
Parenting Chore Time
- Measures based on
a combination of maternal report and interviewer ratings:
HOME-SF total score
HOME-SF Emotional Support subscale
Positive program impacts
occur in aspects of parenting that have previously been identified
as particularly important to the development of children in
poverty. For example, harsh parent-child interaction has been
found to occur with greater frequency among families experiencing
economic hardship. Harsh parent-child interaction, in turn,
is a key contributor to the less favorable adjustment of children
in poverty.
In general, the findings
indicate that the New Chance Program had positive impacts
on parenting behaviors important to development. There are
three caveats, however. First, there were differences on only
a minority of the parenting measures examined. Second, all
but one of the program impacts, that on the HOME-SF Emotional
Support subscale, were small in magnitude ("effect size").
Finally, a single significant finding ran counter to this
pattern of positive impacts: Mothers in the experimental group
received lower Ease of Ideas scores, observed during the mother-child
task that called for eliciting from the child the names of
objects that have wheels. That is, mothers in the experimental
group were observed to be less facile in coming up with hints
and clues for the child. This difference, however, was found
to be attributable entirely to a larger number of mothers
within the experimental group who did not grasp the goal of
this task at all. Thus, this group difference might just as
easily be interpreted as an indication of task or test anxiety,
or of problems with the interviewers explanations of
this task, than as a reflection on the quality of the mothers
parenting behavior.
The research team concluded
that the New Chance Program had positive, albeit modest, impacts
on parenting behavior.
VIII.
Program Components That Contributed to Positive Program Impacts
on Parenting Behavior
Among mothers in the
experimental group within the New Chance Observational Study
sample, greater participation in parenting education classes
was related to more positive parenting behavior. Interestingly,
however, this pattern was also found for participation in
other New Chance Program components.
We looked at four aspects
of experimental group mothers participation in New Chance:
(1) participation in parenting education classes, (2) participation
in a broader set of program activities that addressed parenting
behavior in some way, (3) participation in human capital development
components of the program (that is, components intended to
improve the mothers ability to obtain and keep a job,
including adult education and employability development classes),
and (4) total program participation.
Even after controlling
for baseline characteristics that predicted each of
these aspects of program participation, certain parenting
measures continued to be significantly associated with the
extent of program participation among mothers in the experimental
group. Thus, within this group, scores on the HOME-SF Emotional
Support subscale continued to differ significantly according
to extent of participation as defined in each of the four
ways; and the observational measure of Book Reading Quality
differed according to participation in the human capital development
components of the program as well as in the program overall.
It should be noted
that characteristics we did not have baseline measures of,
and thus could not control for, might be linked both to greater
program participation and to parenting behavior, and these
undocumented variables might help account for the associations
we have noted. These findings nevertheless raise the possibility
that components of programs for young mothers in poverty including
but going beyond parenting education may have positive
implications for parenting behavior. Further study is needed
to explore how and why program components directed at mothers
education or employment skills, and their overall program
participation, might affect their parenting behavior.
IX.
Parenting Behavior as a Predictor of Child Outcomes
The findings on child
outcomes in the New Chance Demonstration present us with a
paradox. Although there were positive impacts on measures
of parenting, children in the experimental group did not
do better in terms of their cognitive and social development
when these were assessed at the 42-month follow-up. On most
measures, there were no program impacts. However, on some
measures there were unanticipated negative program
impacts. For example, mothers in the experimental group described
their children as having less positive social behavior. This
pattern held in both the full demonstration study sample and
the smaller observational study sample.
Clearly, we need to
consider factors other than parenting behavior as contributors
to childrens development for example, mothers
psychological well-being, family economic status, and the
experiences of mothers and children outside the mother-child
relationship. New Chance appears to have had unexpected negative
program impacts on some of these further factors. For example,
mothers in the experimental group in the observational study
sample were more, rather than less, depressed at the time
of the first (18-month) follow-up survey. Mothers in the experimental
group of the observational study sample also reported less
life satisfaction.
We considered both
the role of parenting behavior and variables that measured
other important aspects of the mothers and childrens
lives as predictors of five selected child outcomes within
the observational study sample (childrens total scores
on the School Readiness Component of the Bracken Basic Concept
Scale, the Behavior Problems Index total score as reported
by both mother and teacher, and the Positive Behavior Index
total score as reported by both mother and teacher). We confirmed
that when measures of parenting behavior were taken into account,
our ability to predict childrens scores on several of
these outcomes improved significantly (specifically, the maternal
report of the Behavior Problems Index and Positive Behavior
Index and the teacher report of the Positive Behavior Index).
More supportive and
stimulating parenting thus predicted more optimal developmental
outcomes on specific measures of development. However, in
addition, we found that variables reflecting maternal psychological
well-being (for example, measures of life satisfaction and
of aggravation and stress in parenting) and variables reflecting
the larger social context of the families (for example, measures
of difficult life circumstances and of number of changes of
residence since enrolling in the evaluation) were also significant
predictors of several child outcomes. Greater maternal psychological
distress and greater stress in the larger social context predicted
less positive developmental outcomes.
An important finding
of this study, then, is that while parenting behavior was
a significant predictor of specific child outcomes, it was
not the only predictor. The positive influence of supportive
and stimulating parenting behavior combined with negative
influences of psychological distress in the mother and stress
in the familys larger social environment. Childrens
developmental outcomes reflect influences not only from within
but also outside the mother-child dyad.
Outcomes for children
in the context of an intervention such as New Chance might
improve if the intervention directly addressed these problems
through more intensive mental health intervention for the
mothers; if the "dosage" of program components with
positive implications for childrens development, such
as parenting education, were substantially increased; or if
program elements targeted to the children themselves were
strengthened. Direct observations of New Chance child care
settings placed these child care centers just below the "good"
range in terms of quality. For positive child outcomes to
occur, children from high-risk families may need higher-quality
care. In addition, beyond the first program follow-up (at
18 months), children in the New Chance experimental group
were not found to participate in more child care than those
in the control group. Indeed, the increased child care participation
of children in the experimental group tended to occur only
during the first months of their mothers program participation,
when the mothers were engaged in on-site classes and activities.
Positive program impacts on children may require sustained
participation in high-quality child care.
X.
How Observational Measures of Parenting Contribute to a Study
Such as the Evaluation of New Chance
Measures of parenting
based on direct observation of mother-child interaction contribute
to our understanding of the New Chance Program in several
ways. First, these measures increase our certainty
about program impacts on parenting. If positive impacts
on parenting were found only for maternal report measures,
we might question them on the grounds that mothers in the
experimental group (aware that they had access to New Chance
Program services and that outcomes of the program were being
assessed) could report more favorably because they felt it
to be expected of them. Even interviewers aware of which research
group a family was in could be subject to such "response
biases." Coders of the videotapes were unaware of which
research group a family was in, yet positive program impacts
were found on observational measures.
Second, observational
measures provided information that was different
from and complementary to that provided by interview-based
measures of parenting. For example, a positive program impact
was found on the observational measure of Book Reading Quality,
yet no program impacts were found on the interview-based measure
of cognitive stimulation (the HOME-SF Cognitive Stimulation
subscale). The observational measure looks at the nature
or quality of mother-child interaction in a book reading
context, for example, the mothers fluency, intonation,
and comfort level in reading the book to her child. By contrast,
the HOME-SF measure of cognitive stimulation assesses the
quantity of literacy-related and other stimulating activities:
for example, how many books were in the home, and how
often the mother reads to the child. Without a measure
of the nature or quality of cognitive stimulation, we might
not have known that there were program impacts in this area.
Correlations between observational and interview-based measures
of parenting confirm that these measures are related but do
not substantially overlap.
Finally, we found
the observational measures to be helpful in predicting child
outcomes. When we distinguished among maternal report
scales, HOME-SF subscales, and observational measures as predictors
of the selected child outcomes, we found that the HOME
subscales and observational measures were generally better
predictors than the maternal report scales. We also asked
whether observational measures added to our ability
to predict variation in childrens developmental outcomes
after the maternal report scales and HOME-SF subscales were
already taken into account. We found that for two of
the five selected child outcomes, observational measures
added significantly to our ability to predict child outcomes
even when the other parenting measures had been taken into
consideration.
The fact that the observational
measures do not rely at all on maternal report also helps
eliminate the possibility that associations between parenting
behavior and those child outcomes based on maternal report
(for example, the Behavior Problems Index, as reported by
the mother) are not merely a reflection of common attitudinal
or reporting tendencies across different sets of maternal
report measures.
Thus, observational
measures of parenting behavior provide different information
than that available through interview-based measures of parenting,
diminish concerns about possible response biases and correlated
measurement error, and add significantly to the ability to
predict specific child outcomes. Where the examination of
parenting behavior is a high priority, observational measures
of parenting add substantially to the strength of an evaluation.
Part
II: Methodological Assessment of the New Chance Observational
Study
I.
The Methodological Context for the New Chance Observational
Study
The New Chance Observational
Study lies at the confluence of rising interest in policy-relevant
research among developmental psychologists, interventions
focusing on two generations in a family, and increasing demand
for nontraditional forms of survey research. In attempting
to increase the size and representativeness of samples, some
developmentalists are departing from the familiar model of
laboratory-based research, sometimes supplemented with home
visits, to undertake their data collection through contracted
survey research. Survey research on parenting and child development
has traditionally involved querying parents about their parenting
practices and their childrens development. In recent
years, survey interviewers have also been asked to rate parent-child
interactions and the home environment, and, in a few cases,
to administer structured parent-child interactions similar
to those usually carried out in the child development laboratory.
New Chance, while not alone in its use of survey methods to
study child development, is one of the few studies to use
survey interviewers to conduct observational work with mothers
and children. Within this context, Part II of the monograph
seeks to familiarize readers with the "survey model,"
document how the observational study was conducted, assess
the success of the effort, and consider both specific recommendations
for future work and broader implications for research design.
This study affords
a unique opportunity for examining methodological issues in
the measurement of parenting and child outcomes for two reasons.
First, it taps a diverse set of measures and data sources:
taped mother-child interactions coded under rigorous conditions
in university laboratories, self-reports of mothers, and ratings
by survey interviewers of mother-child interactions and the
home environment. Just as important as the rich variety of
domains tapped is the fact that the study was conducted within
the framework of a survey research model, while "stretching"
this model to exploit it in innovative ways.
II.
Implications of Conducting Research Within a Survey Model
Chapter 10 of the monograph
seeks to enhance the value and accessibility of the survey
field to social scientists who have not made survey research
the primary focus of their careers and to begin to bridge
the communication gap between survey researchers and their
colleagues even from the same disciplines who
may emphasize a substantive research agenda more than a method.
Without a full appreciation of the constraints of the survey
model, researchers who commission survey work may have difficulty
managing it and even find themselves disappointed with the
results. At the same time, they will be shortchanged if they
look to the field primarily for a data collection capability
and fail to heed its lessons on survey-based measurement.
In contrast to an academically
oriented model, survey research is built on a division of
labor between those responsible for the conceptual and analytical
aspects of research and those who actually collect the data.
The survey model places responsibility for data collection
in the hands of "distant proxies" for "absent
researchers." These proxies, the survey interviewers
who collect data on surveys ranging from small local studies
to large recurring government surveys, are neither assumed
to possess nor expected to master a conceptual appreciation
of the research in which they participate. For these reasons,
survey researchers provide interviewers with explicit rules
to direct them through the data collection rules that,
in theory at least, require minimal judgment to apply. The
resulting survey model is characterized by an orientation
toward production, a contrived and stylized format for the
interaction of interviewer and respondent, and precise programming
and standardization of interviewer behaviors. Designing sound
data collection instruments and procedures involves accommodating
to these three aspects of the survey model.
III.
Turning to the Survey Field for Help with Measurement Issues
The constraints, or
"rules," of the survey model may be viewed as potential
limitations in conducting social science research, but the
survey communitys trove of research on survey measurement
can be viewed as a valuable resource. The underlying focus
of most of this work is the reduction of error in surveys.
The bulk of
the measurement literature has focused on the design of measurement
instruments, that is, questionnaires, and less on other aspects
of measurement, such as interviewer or mode effects. If this
literature yields an overarching lesson, it is a humbling
one: that there are many, many features of questions and questionnaires
that can affect survey response. An awareness of such measurement
threats is helpful both in developing measures and related
data collection instruments and in assessing their likely
strengths and limitations.
The survey literature
also speaks to the ways in which interviewers may affect measurement
in a study like this. Evidence for the prominence of interviewer
effects in situations requiring more judgment or unprogrammed
behavior is especially relevant to the present work, which
required interviewers to make substantive ratings of the home
environment and mother-child interaction, obtain time-use
information through a series of open-ended probes, and administer
a scripted observational protocol, while applying general
principles to unscripted situations.
Given the importance
of interviewers and the expansion of their responsibilities
with ever more challenging studies, focusing on the cognitive
demands of their tasks will help in assessing what is sensible
to ask them to do and helping them to do it. The last decade
or so has seen the emergence of a broader interest in cognitive
aspects of survey response, beyond simply the recall of information.
This interest has been directed primarily toward the tasks
facing respondents during an interview, such as the
strategies they use to estimate and report the frequency of
a particular behavior. The cognitive framework can also be
applied to the cognitive tasks faced by interviewers
during a survey interaction, by examining, for example, the
ability of interviewers to process the information necessary
for making substantive ratings at the same time they are reading
interview questions and recording answers. Viewing the demands
of the survey interaction on both respondents and interviewers
from a cognitive perspective provides a helpful framework
for integrating what is known about the instruments used to
collect data, the interviewers who administer them, and the
respondents who provide the data.
IV.
Steps in Implementing the New Chance Observational Study
As discussed in Chapter
11, and summarized below, implementing the observational research
that is the central subject of this monograph involved both
the design of data collection instruments and procedures and
the data collection effort itself. In carrying out these tasks,
we confronted and sought to address a host of survey measurement
issues, most notably the overarching issue of adherence to
the goals and objectives of the "absent researchers"
who place their research in the hands of survey interviewers.
Our approach included the following steps.
- Tasks developed
in university laboratories were adapted for survey administration
by strictly scripting them in the format of a structured
survey questionnaire to ensure standardized delivery by
survey interviewers.
Survey interviewers
are not expected to have the appreciation of a studys
theoretical underpinnings that would allow them to work from
only a researchers semistructured outline. Therefore,
the strategy for realizing the objectives of the "absent
researchers" was to program interviewer behavior in the
observational session carefully. This meant providing interviewers
with a data collection instrument resembling a survey questionnaire,
which specified the precise language to be used and the actions
to be taken. The instrument included detailed instructions
for presenting, arranging, and withdrawing the various props
used in the tasks (book, games, and gift) and for coordinating
management of the props with the script. Also included were
language and instructions for verifying that the mothers understood
the objectives of the task, decision rules for determining
how much time to spend on each, and, for one task, decision
rules as to whether a simple or complex version, or both versions,
of the task was to be administered.
