The Washington State Needs Assessment Household Survey (WANAHS)
The WANAHS was a statewide survey of 6,713
adults 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. The Washington State Department of Social
and Health Services (DSHS) Research and Data Analysis (RDA) section
conducted the project on behalf of the DSHS Division of Alcohol and
Substance Abuse (DASA). Telephone interviewing was conducted by Washington
State University's Social and Economic Sciences Research Center. The
survey achieved a response rate of 50 percent and a cooperation rate of 69
percent.
The WANAHS over sampled minorities and lower-income
populations in order to facilitate demographic analyses. The WANAHS sample
was weighted to U.S. Census data to provide direct statewide estimates of
substance use and the need for substance abuse treatment services. Further
details about survey methods are included in a forthcoming state report.
