Other Study Components

Time Diary Activity File. Time diaries were completed for children who resided in families that were selected for a supplemental in-person interview. The Time Diary Activity File contains one record for each activity reported by children on two randomly-assigned days. Each record contains information about the type of activity children were engaged in (primary and secondary), start time and end time, duration, who else was present, and where the activity occurred. (Information about the names of television shows, books, web sites, and apps used during activities are not included with this release.)

Time Diary Aggregated Activity File. The Aggregated Time Diary File includes one record for each child for whom a time diary was completed. For each coded activity, the total time a child spent in that activity over the course of a day is provided for the weekday and weekend report separately.

Time Diary Questionnaire File. The Time Diary Questionnaire File includes one record for each child for whom a time diary was completed. Contents describe the time diary administration, including the day of the week each diary was completed, who filled out the diary, and whether the diary described a typical day in the child’s life.

Household Roster File. A household roster collected during the initial screening interview gathered information on all individuals living in a CDS child’s household. The CDS-2014 Household Roster File includes one record for each household member residing with a CDS child (N=10,453). Contents include the CDS household identifier (R14CDSHID) and individuals’ PSID 1968 ID and person number (R14ID68 and R14PN), position in the CDS roster, age in years, and sex. A person type indicator describes whether each individual is a CDS child, a CDS primary caregiver, or other household member (R14TYPE). In 24 households, two primary caregivers are present, each caring for a different child or children. The variable R14CDSHPIN may be used to distinguish caregivers who coreside and have a common CDS household identifier.

NOTE: Seventy-nine individuals observed in a CDS-2014 household have never appeared in a PSID household at the time of the Core PSID interview and have never been reported in a PSID participant’s marriage or birth history. These individuals have not been assigned a PSID person number (i.e., no value on ER30002) and information about them cannot be merged on to any other individual-level information in the PSID Data Center. These individuals have been assigned a value of 999 for R14PN.

Demographic File. The Demographic File includes one record for each child who appears in the CDS-2014 public release (N=4,333). This file contains study information including the interview components completed for the child and date of interview; information about the child including his/her race ethnicity and birth weight (pulled in from the PSID birth history file); interviewer observations about the child (in-home supplement sample only); and child and primary caregiver sampling weights.

The Demographic File also contains information on the age, sex, and relationship to CDS child of all household members present at the time of the CDS-2014 screening interview (variables listed from X14R01SEX to X14R15UNC2). Individual household members are indexed by their position in the household roster (see above for information on the Roster File). For example, X14R01SEX reports the sex of Person 1 on the Household Roster, X14R02SEX reports the sex of Person 2, etc. The order in which the screener respondent listed household members determines an individual’s position on the roster. A CDS child’s position in the roster is reported in X14WHICH. The primary caregiver’s relationship to a CDS child is described in X14PCGRLSP.
