Summary View help for Summary
The National Social Life, Health and Aging Project (NSHAP) is a population-based study of health and social factors on a national scale, aiming to understand the well-being of older, community-dwelling Americans by examining the interactions among physical health, illness, medication use, cognitive function, emotional health, sensory function, health behaviors, and social connectedness. It is designed to provide health providers, policy makers, and individuals with useful information and insights into these factors, particularly on social and intimate relationships. The National Opinion Research Center (NORC), along with Principal Investigators at the University of Chicago, conducted more than 3,000 interviews during 2005 and 2006 with a nationally representative sample of adults aged 57 to 85. Face-to-face interviews and biomeasure collection took place in respondents' homes. Wave 3 was conducted from September 2015 through November 2016, where 2,409 surviving Wave 2 respondents were reinterviewed, and a New Cohort consisting of adults born between 1948 and 1965 together with their spouses or coresident partners was added. All together, 4,777 respondents were interviewed in Wave 3. The following files constitute Wave 3: Core Data, Social Networks Data, Disposition of Returning Respondent Partner Data, and Proxy Data.
Included in the Core files (Datasets 1 and 2) are demographic characteristics, such as gender, age, education, race, and ethnicity. Other topics covered respondents' social networks, social and cultural activity, physical and mental health including cognition, well-being, illness, history of sexual and intimate partnerships and patient-physician communication, in addition to bereavement items. In addition data on a panel of biomeasures including, weight, waist circumference, height, and blood pressure was collected. The Social Networks (Datasets 3 and 4) files detail respondents' current relationship status with each person identified on the network roster. The Disposition of Returning Respondent Partner (Datasets 5 and 6) files detail information derived from Section 6A items regarding the partner from Waves 1 and 2 within the questionnaire. This provides a complete history for respondent partners across both waves. The Proxy (Datasets 7 and 8) files contain final health data for Wave 1 and Wave 2 respondents who could not participate in NSHAP due to disability or death

The identification variable SU_ID can be used to link the respondent records across the waves of the survey.
Study Design View help for Study Design
As in Wave 2, all questions were asked entirely in the in-person interview or the leave-behind questionnaires. In Wave 3, though, there are separate leave-behind questionnaires for the new cohort and original cohort. Users can refer to the related data collections ICPSR 20541 and ICPSR 34921, National Social Life, Health, and Aging Project (NSHAP): Waves 1 and 2 for further study design information, as well as the Original P.I. Documentation in the ICPSR Codebook and visit the NORC at the University of Chicago Web site.
Sample View help for Sample
Although the New Cohort added in Wave 3 was selected from a national frame, it was not the same as that used to select the Original Cohort. As with the Original Cohort, the New Cohort was obtained from a probability sample of U.S. adults meeting the age criteria, with African-Americans and Hispanics sampled at a higher rate. Spouses or coresident partners of sampled respondents were also included. Users may refer to ICPSR 20541 and ICPSR 34921, National Social Life, Health, and Aging Project (NSHAP): Waves 1 and 2 for further sampling information, as well as the Original P.I. Documentation in the ICPSR Codebook and visit the NORC at the University of Chicago Web site.

2017-10-25 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.
Weight View help for Weight
The data are not weighted, but contain two weight variables within the Part 1 Core data file, which users may wish to apply during analysis. Respondent-level weights representing the inverse probability of selection are contained in the variable WEIGHT_SEL. A second set of weights incorporating a non-response adjustment based on age and urbanicity is contained in the variable WEIGHT_ADJ. Both sets of weights are scaled to sum to the final sample size (3,005).
The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
This study is maintained and distributed by the National Archive of Computerized Data on Aging (NACDA), the aging program within ICPSR. NACDA is sponsored by the National Institute on Aging (NIA) at the National Institutes of Heath (NIH).
