WANAHS Background
The WANAHS was a statewide survey of 6,713 adult household residents designed to measure the prevalence of substance use and the need for substance abuse treatment. Data were collected from February 2003 through February 2004. Funding was provided by a grant from the Federal Center for Substance Abuse Treatment. These data update a previous set of reports produced in 1999 based on 1993-94 survey data.
The Washington State Department of Social and Health Services (DSHS) Research and Data Analysis Division conducted the project on behalf of the DSHS Division of Alcohol and Substance Abuse.
The WANAHS over sampled young adults, minorities, and lower-income populations to facilitate demographic analyses. The WANAHS sample was weighted to U.S. Census data to provide direct statewide estimates of substance use and need for substance abuse treatment services. County-level estimates are derived from a synthetic estimation process. This process is explained in greater detail in the county reports.
