Summary: |
The overall purpose of this study was to examine the influence of variations in early childcare histories on the psychological development of infants and toddlers from a variety of family backgrounds. This general objective was addressed through a prospective, longitudinal study of the experiences of 1,364 children and their families, which took into account the complex interactions among child characteristics and those of the human and physical environments in which the children were reared. Research GoalsThe specific research aims were as follows:
Data File Organization158 data files were compiled for this study and are organized into 4 main groups:
Included in this phase of the study are the output of several third-party software programs that were used during Phases II, III and IV to collect data for specific tasks or activities. These programs produced one output data file per subject, which were combined to produce some of the raw data files for those studies. The original program output is included as expanded documentation in this phase of the study. Training Workshop RecordingsA three day summer training workshop on the SECCYD was put on by the NICHD at the Inter-University Consortium for Political and Social Research in Ann Arbor, Michigan. Recordings of that workshop, coordinated with the Powerpoint slides used during presentations, are freely available to the public at the addresses listed below.

census/enumeration data, clinical data, observational data, survey data |
Data Collection Notes: |
A wide range of adolescent outcomes and contextual features were assessed in one laboratory and one home visit at age 15. Additional information was collected from health and pubertal maturation examinations at ages 13.5, 14.5, and 15.5, from monitored physical activity at age 15, from analyses of middle school and high school transcripts, and from surveys of middle school and high school personnel. The NICHD Study of Early Child Care and Youth Development was conducted by a network of investigators called the NICHD Early Child Care Research Network. The network was led and managed by a steering committee that included an independent chairperson, one representative from each of the grantee sites, one representative from the data center, and one representative from NICHD. The steering committee established policies and procedures that governed the operations of the network. The progress of the study was monitored by NICHD and by the steering committee with guidance from an advisory board which was nominated by the director of NICHD. |
Methodology |
|
Study Purpose: |
The principal purpose of Phase IV of the NICHD-SECCYD was to investigate how earlier functioning and experiences in concert with contextual and maturational factors in adolescence, influence social relationships, health, adjustment, and intellectual and academic development during middle adolescence. |
Study Design: |
The SECCYD is a multi-site, prospective, longitudinal study of the experiences of 1,364 children and their families (1,056 children and families were enrolled for Phase IV). Respondents were sampled from a catchment of some 6,189 children. Children's development was assessed via trained observers, interviewers, questionnaires, and direct testing. Measures were taken on many facets of children's development, such as social, emotional, intellectual, and language development, behavioral problems and adjustment, and physical health. |
Sample: |
Participants were selected in accordance with a conditionally random sampling plan, which was designed to ensure that the recruited families (a) included mothers who planned to work or to go to school full-time (60 percent) or part-time (20 percent) in the child's first year, as well as some who planned to stay at home with the child (20 percent), and (b) reflected the demographic diversity (economic, educational, and ethnic) of the sites. Both two-parent and single-parent families were included. The major exclusionary criteria used were (a) mothers younger than 18 years of age at the time of the child's birth, (b) families who did not anticipate remaining in the catchment area for at least 3 years, (c) children with obvious disabilities at birth or who remained in the hospital more than 7 days postpartum, and (d) mothers not sufficiently conversant in English. Analyses have indicated that the data do reflect the natural distributions of these factors in the catchment. Therefore, inferences from this data can be made directly to the catchment without back-weighting for the sampling factors. In addition, analyses have shown that the NICHD data reflect to large degree the natural distributions of certain factors measured in the 1990 Census data. However, the NICHD data are not representative in the statistical sense, and therefore inference to the nation as a whole is not possible. Comparisons to other databases, national or otherwise, should be made with extreme caution. |
Mode of Data Collection: |
computer-assisted personal interview (CAPI), computer-assisted telephone interview (CATI), coded on-site observation, cognitive assessment test, face-to-face interview, mail questionnaire, self-enumerated questionnaire, on-site questionnaire, telephone interview |
Description of Variables: |
The 19 Analytical Data Sets (ADS) contain composite variables, created from the raw data by Quantitative Systems Laboratory (QSL) at Vanderbilt University, to be psychometrically and distributionally acceptable for analytical analysis of the study hypotheses. The 7 Supplemental Data Set were produced by Research Triangle Institute (RTI) and contains new and revised analysis variables, across-time mean scores, and primary composites. The 4 Raw Census-Related Data Sets were produced using geocoded addresses for survey respondents to match block group-level data from the 2000 Census for investigators to create additional measures of interest from the geocoded addresses. The CENS2000 raw dataset contains 1,423 block group variables for 2,891 address records with end dates after December 31, 1995, for 1,159 study children. The 128 Raw Data Sets contain the direct item-level data collected per instrument. |
Response Rates: |
During Phase I of the study (1991-1994), a cohort of 1,364 children and their families were recruited at 1 month of age and studied intensively through age 3. Phase IV of the study (2005-2008) followed a cohort of 1,056 enrolled children and families. |
Extent of Processing: |
All archived data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. The archive also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, the archive performed the following processing steps for this data collection:
