Version V2

This follow-up to the NATIONAL SURVEY OF SELF-CARE AND AGING: BASELINE, 1990-1991 (ICPSR 6718) was conducted in 1994 to continue examination of the health status and self-care practices of individuals aged 65 or older who were interviewed at baseline during 1991. Telephone interviews (Part 1) were conducted with individuals who were interviewed at baseline. A proxy was interviewed if the subject was too ill or cognitively unable to respond. Included were questions about the type and extent of self-care behaviors for activities of daily living, management of chronic conditions (through self-care activities, equipment use, and environmental modifications), and medical self-care for acute conditions, along with questions regarding change in health status since baseline, health service utilization, nursing home visits, and sociodemographic/economic status. For subjects who had been institutionalized since baseline (Part 2), interviews were conducted with proxies. Information was gathered regarding demographic status, living arrangements prior to institutionalization, and reasons for institutionalization. For subjects who had died since baseline (Part 3), information was again gathered through interviews with proxies. Questions covered nursing home admissions and date and place of death. Part 4 consists of data from interviews conducted at baseline (ICPSR 6718) merged with interviews conducted at this follow-up.

The data and SAS and SPSS data definition statements were extracted from SAS transport files.

Data from this follow-up has been linked with the baseline data (ICPSR 6718) using the variable ARCHIVID.

The stratified random sample of noninstitutionalized Medicare beneficiaries 65 years of age and older was drawn from 50 primary sampling units (PSUs), 38 urban and 12 rural. Stratification was by gender and three age groups (65-74, 75-84, 85 or older).

1999-01-21 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:

  • Created online analysis version with question text.
