DATA INFORMATION: SECOND SUPPLEMENT ON AGING (SOA II) Date Added to NACDA Collection: Nov. 16, 1998 Date Updated: Nov. 16, 1998 Investigator: United States Department of Health and Human Services. National Center for Health Statistics. TITLE: NATIONAL HEALTH INTERVIEW SURVEY, 1994: SECOND SUPPLEMENT ON AGING Abstract: The National Health Interview Survey, 1994: Second Supplement on Aging (SOA II), conducted approximately 10 years after the original SOA (see NATIONAL HEALTH INTERVIEW SURVEY, 1984 [ICPSR 8659], Parts 6 and 7), had four specific aims: 1) Provide a replication of the first SOA to determine whether changes had occurred in the level of disability among older persons between 1984 and the mid-1990s. 2) To elicit information on the causes and correlates of changes in health and functioning in older Americans, including background demographic characteristics, health behaviors, and attitudes, preexisting illness, and social and environmental support. 3) Describe the sequence and consequences of health events, including utilization of health care and services for assisted community living, on the physiological consequences of disability such as pain and fatigue, on social consequences such as changes in social activities, living arrangements, social support, and use of community services, and on the deployment of assisted living strategies and accessibility of technological and environmental adaptations. 4) To serve as the baseline for another national longitudinal study focusing on older Americans, the Second Longitudinal Study of Aging (LSOA II) (for the first LSOA see NATIONAL HEALTH INTERVIEW SURVEY: LONGITUDINAL STUDY OF AGING, 70 YEARS AND OVER, 1984-1990 [ICPSR 8719]).; Collection Contents: Data file and machine-readable documentation (PDF) Series Name " NATIONAL HEALTH INTERVIEW SURVEY SERIES" Background Information: Conducted since 1969 by the National Center for Health Statistics, the National Health Interview Surveys (NHIS) series (formerly titled the Health Interview Surveys) obtains information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. The series provides a continuous sampling and interviewing of the civilian, noninstitutionalized population of the United States through core surveys and supplemental datasets. Supplements collect data on topics such as AIDS knowledge and attitudes, child health care and immunization, dental care, substance abuse, hospitalization, preventive care, nursing care, prosthetic appliances, and self-care. Supplements on Aging (SOA) conducted in 1984 and 1994 and the 1984-1990 Longitudinal Study of Aging (LSOA) provide information on the causes and correlates of changes in the health and functioning of older Americans. Another component of the NHIS is the National Health Interview Survey on Disability (NHIS-D). Begun in 1994, the NHIS-D was designed to collect data that can be used to understand disability and to develop public policy on disability.; IMPORTANT CAUTION: In preparing the data files for this collection, the National Center for Health Statistics (NCHS) has removed direct identifiers and characteristics that might lead to identification of data subjects. As an additional precaution NCHS requires, under Section 308(d) of the Public Health Service Act (42 U.S.C. 242m), that data collected by NCHS not be used for any purpose other than statistical analysis and reporting. NCHS further requires that analysts not use the data to learn the identity of any persons or establishments and that the director of NCHS be notified if any identities are inadvertently discovered. ICPSR member institutions and other users ordering data from ICPSR are expected to adhere to these restrictions. TIME.PERIOD: 1994 DATE.OF.COLLECTION: 1994-1995; COLLECTION NOTES: 1) Per agreement with NCHS, ICPSR distributes the data files and technical documentation in this collection in their original form as prepared by NCHS. 2) The codebook, data collection instrument, and frequencies are provided as a Portable Document Format (PDF) file. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader.
NACDA's MISSION "The National Archive of Computerized Data on Aging (NACDA), located within ICPSR, is funded by the National Institute on Aging. NACDA's mission is to advance research on aging by helping researchers to profit from the under-exploited potential of a broad range of datasets. NACDA acquires and preserves data relevant to gerontological research, processing as needed to promote effective research use, disseminates them to researchers, and facilitates their use. By preserving and making available the U.S.'s largest library of electronic data on aging, NACDA offers opportunities for research on major issues of scientific and policy relevance."
