Scope of Study

Summary:

The National Medical Expenditure Survey (NMES) series provides information on health expenditures by or on behalf of families and individuals, the financing of these expenditures, and each person's use of services. The Survey of American Indians and Alaska Natives (SAIAN) was designed in collaboration with the Indian Health Service (IHS), and used the same data collection instruments, interview procedures, and time frame as the NMES Household Survey component. However, the SAIAN differed from the Household Survey in several respects. The SAIAN sample was interviewed only three times and was not given the supplements on long-term care, caregiving, and care-receiving. Also, SAIAN respondents were asked additional questions on topics such as use of IHS facilities and traditional medicine, and were given a modified self-administered questionnaire with separate versions for adults and children. Interviewers for the SAIAN were mainly American Indians or Alaska Natives, and about 20 percent of the interviews were not conducted entirely in English. Of these, approximately 40 percent were conducted entirely in the native language of the respondent. Public Use Tape 20P contains detailed information on eligibility status, interview dates, demographic characteristics (age, marital status, military service, education, income), employment and insurance, link variables, and other survey administration variables for all persons in the sample. The Round 1 person characteristics previously released in NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: SURVEY OF AMERICAN INDIANS AND ALASKA NATIVES, ROUND 1 PERSON-LEVEL FILE [PUBLIC USE TAPE 11] (ICPSR 9689) are being replaced by the data contained in this collection.

Subject Term(s):

Geographic Coverage:

United States

Time Period:

1987

Date(s) of Collection:

1987

Universe:

Data Type:

survey data

Data Collection Notes:

The principal investigator notes that the data in Public Use Tape 20P are preliminary in nature and are being released prior to final cleaning and editing, in order to provide access to information from the SAIAN. Public Use Tape 20 will serve as the base tape for all NMES SAIAN Public Use Tapes containing full-year 1987 data. This collection is superseded by NATIONAL MEDICAL EXPENDITURE SURVEY, 1987: SURVEY OF AMERICAN INDIANS AND ALASKA NATIVES, POPULATION DATA, DATA FROM THE HEALTH STATUS QUESTIONNAIRE AND ACCESS TO CARE SUPPLEMENT, AND EXPENDITURES AND SOURCES OF PAYMENT DATA [PUBLIC USE TAPE 37] (ICPSR 6490).

Methodology

Sample:

The sample is a stratified area probability design with three stages of sample selection: (1) selection of primary sampling units (PSUs), which are counties or groups of contiguous counties (in Alaska, the county equivalents developed by the state of Alaska and the Census Bureau for statistical purposes were employed), (2) selection of segments within PSUs, (3) selection and screening of dwelling units within segments. Based on the results of the screening, all dwelling units including persons eligible for IHS services were selected in the SAIAN. The sample frame included all counties in the United States including or adjacent to reservations of federally-recognized tribes or Alaska Native villages. For cost considerations, the sample frame was truncated to remove counties with the lowest concentrations of eligible persons, and disproportionate sampling was applied to remaining counties with low concentrations of American Indians.
