California Families Project [Sacramento and Woodland, California] [Restricted-Use Files] (ICPSR 35476)

Principal Investigator(s): Robins, Richard, University of California, Davis; Conger, Rand, University of California, Davis

Summary:

The California Families Project (CFP) is an ongoing longitudinal study of Mexican origin families in Northern California. This study uses community, school, family, and individual characteristics to examine developmental pathways that increase risk for and resilience to drug use in Mexican-origin youth. This study also examines the impact that economic disadvantage and cultural traditions have in Mexican-origin youth. The CFP includes a community-based sample of 674 families and children of Mexican origin living in Northern California, and includes annual assessments of parents and children. Participants with Mexican surnames were drawn at random from school rosters of students during the 2006-2007 and 2007-2008 school year. Data collection included multi-method assessments of a broad range of psychological, familial, scholastic, cultural, and neighborhood factors. Initiation of the research at age 10 was designed to assess the focal children before the onset of Alcohol, Tobacco, and Other Drug (ATOD) use, thus enabling the evaluation of how hypothesized risk and resilience mechanisms operate to exacerbate early onset during adolescence or help prevent its occurrence. This study includes a diversity of families that represent a wide range of incomes, education, family history, and family structures, including two-parent and single-parent families.

The accompanying data file consists of 674 family cases with each case representing a focal child and at least one parent (Two-parent: n=549, 82 percent; Single-parent: n=125, 18 percent). Of the 3,139 total variables, 839 pertain to the focal child, 1,376 correspond to the mother, and 908 items pertain to the father.

Please note: While the California Families Project is a longitudinal study, only the baseline data are currently available in this data collection.

Smallest Geographic Unit:    City of School District

Geographic Coverage:    California, Sacramento, United States

Time Period:   

  • 2006--2007

Date of Collection:   

  • 2006--2007 (Wave 1)

Unit of Observation:   

Individual; Family

Please note that each case potentially includes a focal child, a mother, and a father. As such, cases or whole families can be analyzed against other cases, or any combination of individual analysis is also permitted with the clear delineation of variable prefix of (C) Child, (M) Mom, and (D) Dad.

Universe:    Mexican-origin children being raised in two-parent or single-parent families from Sacramento and/or Woodland, California.

Data Type(s):    survey data

Data Collection Notes:

This data collection provides only the baseline data (Wave 1) collected between 2006 and 2007.

Full followups were conducted with the cohort in some waves, while partial assessments were conducted in other waves. The followup data are not currently available in this collection. Please see the CFP codebook for information regarding variation across study waves.

ICPSR made revisions to variable labels for each dataset for clarity and consistency across respondent groups. The data file is ordered according to the sequence in which sections appear in the CFP codebook.

ICPSR masked string variables and removed date of birth variables to minimize disclosure risk. ICPSR also de-identified and randomized school identifiers.

Some variables were coded by the study team from video observation of participant family interaction. Participants were coded one at a time for both verbal and non verbal behavior.

The CFP Codebook is available in PDF as data documentation and provides individual questions in both English and Spanish. However, the ICPSR codebook only provides the English version.

Methodology

Study Purpose:    The purpose of this study is to examine community, school, family, and individual characteristics that promote the child's academic and social competence and reduce emotional and behavioral problems during the transition from late childhood to early adolescence.

Study Design:   

This study consisted of multiple waves, each one year apart. All focal children were in fifth grade at the start of the study. Research staff interviewed participants in their homes. These interviews were conducted in Spanish or English, depending on the participant's preference. Participant mothers provided demographic information about the family and household members. Limited assessment interviews took place during other waves. This collection is currently limited to Wave 1 data.

Sample:    The families were drawn at random from 2006-2007 and 2007-2008 school rosters in the Woodland, CA, and Sacramento, CA, school districts. Only families with Mexican surnames were recruited for participation in the study.

Time Method:    Longitudinal: Panel

Weight:    None

Mode of Data Collection:    computer-assisted personal interview (CAPI), coded video observation

Description of Variables:   

Information regarding individual groups and variables appear within the CFP codebook. Each variable group heading is followed by a table containing information regarding which wave contains the section, the variable section description, the number of questions asked of each type of respondent, as well as letter coding both to identify respondent and to reference to whom a respondent is referring.

The California Families Project codebook contains 95 question sections across 5 waves. Wave 1 features 79 question sections of the 95 total representing 83 percent of all question sections.

Of 67 total question sections addressed to the focal child across waves, Wave 1 features 49 question sections representing 73 percent.

Of 71 total question sections addressed to the respondent mother across waves, Wave 1 features 55 question sections representing 77 percent.

Of 66 total question sections addressed to respondent father across waves, Wave 1 features 46 question sections representing 69 percent.

Response Rates:    Of the recruited families, 72.6 percent in the study agreed to participate.

Extent of Processing:   ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR 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, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Checked for undocumented or out-of-range codes.
