  • Abstract

    Understanding How Personal Networks Change: Wave 1 (UCNets) is the University of California Berkeley Social Networks Study, a longitudinal study with the objective of understanding how network composition changes over time as a result of life course transitions - e.g., graduation, marriage, retirement or widowhood - and how these changes are related to health status and outcomes. Using mostly addressed-based sampling from six San Francisco Bay Area counties, the study recruited participants in two age groups (cohorts) - 21-30 year-olds and 50-70 year-olds -- to maximize the possibility of experiencing a life transition. There are 3 waves of interviewing. The first interview, Wave 1, was May 2015 through January 2016. The re-interview for Wave 2 was conducted in Feb-June 2017, and Wave 3 was during Feb-May 2018. In Wave 1, the majority of respondents completed a face-to-face (FTF) survey, with the rest filling out a comparable web survey. In Wave 2 about half completed the FTF survey, and in Wave 3, about one-quarter. The survey contains items regarding households, personal networks, family milestones, employment, health status and behavior, personality and demographic characteristics.
  • Methods

    Using an address-based sampling (ABS), potential respondents were sent a letter inviting them to participate in the survey. The letter directed them to call a toll-free number or visit a website to take a screener survey to confirm age group, as well as randomize the selection by age group and within age group. Then qualifying respondents were randomly selected such that 3 out of 4 were directed to a face-to-face (FTF) survey and the others to a web survey.
  • Methods

    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: Checked for undocumented or out-of-range codes..
  • Methods

    Response Rates: Among the older population, the cumulative response rate was about three percent.
