1994-1995 National Health Interview Survey on Disability, Complete Phase II
National Center for Health Statistics

Since 1957, the National Center for Health Statistics (NCHS) annually conducts a National Health Interview Survey (NHIS) of the U.S. noninstitutionalized civilian population, which consists of approximately 122,000 individuals in 48,000 households. The NHIS consists of a core questionnaire and supplements. The core questionnaire is aimed at a continuous assessment and analysis of health trends in the United States, and its topics-basic health, socioeconomic and demographic data-do not vary much across years. Each year, one or more supplements are added to this core questionnaire in order to reflect public health data needs. National Health Interview Survey on Disability, Phase I (NHIS-D) was one of the supplements included in the NHIS for 1994 and 1995 (complete-merged 1994/95-Phase I data and documentation are available as RADIUS data set 35-36). The NHIS-D, Phase I was used as a screening device to determine eligibility for Phase II, which collected specific data on service use and expenditures as well as aspects of daily life of people with disabilities. The NHIS-D, Phase II included a questionnaire administered to children and a separate questionnaire administered to adults. The Child survey includes information on utilization and the need for services, functional assessment, and the impact of the child's disability on the family. The 1994 and 1995 Child surveys were merged and archived by RADIUS staff as Data Set 37-38. Data Set 37-38 contains 1,199 variables and 6,983 cases. The Adult questionnaire obtained extensive information on issues such as employment, transportation needs, personal assistance needs, use of services and benefits, and participation in social activities. The 1994 and 1995 Adult surveys were merged and archived by RADIUS staff as Data Set 39-41. Data Set 39-41 contains 2,534 variables and 25,805 cases. An additional Outcome file, archived as RADIUS Data Set 42, provides information on the response or non-response of Phase I respondents eligible for either the Adult or Child phase II. Data Set 42 contains 4 variables and 202,560 cases. Identification variables are available to link NHIS-D respondents between Phases (I/II) as well as within households (Child/Adult).
