The California Health Interview Survey has a population-based sample of 55,000 adults. Separate adult, adolescent and child questionnaires were administered in English, Spanish, Korean, Vietnamese, Mandarin, Cantonese, and Khmer. Topics selected for inclusion were based on the data needs of target audiences, and the ability to obtain reliable information in a 30-minute telephone interview. Survey topics include, but are not limited to: prevalence and management of selected health conditions; health behaviors; health insurance; access to care; public program participation and eligibility; dental health; mental health; child care; and demographics. Collecting high quality data was achieved by selecting items that had been tested in the general population, wherever possible. Several new items were developed and others were adapted for telephone administration. All items were pre-tested on respondents from different demographic groups. Pretest respondents were debriefed extensively and questions revised accordingly. During full-scale data collection, a quality assessment methodology was implemented to evaluate the reliability of responses, identify problematic questions and response categories, and determine how well the questions performed in non-English languages. Trained monitors listened to interviews in all languages except Khmer, and completed quality assessment forms as they listened. Additional components included interviewer debriefings and data analysis. This quality assessment effort was undertaken to assist in data interpretation, and to improve survey items for the next cycle of California Health Interview Survey, which will be fielded in 2003.
Learning Objectives: The California Health Interview Survey (CHIS) is a large population-based assessment of health and health care access designed to provide estimates at the local level and for California's ethnically diverse population. This session will provide information on the use of CHIS data to measure health disparities based on race/ethnicity, income, age, gender and sexual orientation, immigration status and citizenship, and geography, including urban-rural place of residence. Presenters will describe scientific and political factors involved in the development of CHIS; the design of the 55,000 household CHIS sample; methods of assuring quality of health, health insurance, access, and other measures; methods of multicultural and linguistic adaptation of survey measures; confidentiality protection policies; and the dissemination of data and results to diverse users.
