Recent reports at the state and national levels show that substance use among children, adolescents, and young adults has been growing since the early 1990s. Details on risk factors and on protective factors for adolescent substance abuse prevention in the state of Washington are presented in this report. It provides measures at the county and state level in the form of indicators or proxy measures. At the county level, 56 indicators of risk factors and 10 additional indicators of youth problem behaviors were identified and collected from over 30 different existing data sources. No county-level indicators of protective factors were obtained. The county and regional data are aggregated to provide statewide information. General interpretations on risk and protective factors and of youth problem behaviors are provided by comparing state trends to national trends and by analyzing county-level geographic patterns. Findings on the three trends and patterns are summarized in three tables following the text of the overview. It is emphasized that prevention programs and interventions should be aimed at reducing risk factors and enhancing protective factors, rather than reducing or enhancing particular proxy measures or indicators.
