What is the California Health Interview Survey?
The California Health Interview Survey (CHIS)
is a biennial telephone survey that provides population-based, standardized health-related
data from households selected from all 58 counties in the state. Fielded for the first time in 2001,
the survey is designed to provide information on:
- the health of California's adults and children, including physical and mental health status, prevalence and management of
chronic diseases, and diet and exercise;
- health insurance coverage, access to preventive and other health services, and barriers to use of health services; and
- eligibility for and participation in state health programs.
California has the nation's most racially, ethnically, and linguistically diverse population. As a result, the health and health
care needs of these population groups is an important focus of the survey. Groups of particular interest include African-Americans,
Latinos and Hispanics, Native Americans and Alaska Natives, and Asian-Americans and Pacific Islanders. The 2001 survey was culturally
adapted for and translated into five languages: Spanish, Chinese, Vietnamese, Korean, and Khmer (Cambodian).
NCI has helped fund CHIS since its inception. The survey is carried out collaboratively by
the UCLA Center for Health Policy Research,
the California Department of Health Services,
and the Public Health Institute.
