Only 5.7% – 12.5% of adults achieve meaningful improvement in their psychological and social functioning after receiving treatment (WSIPP report 2008).
Poor results are corroborated statewide.
Washington State Institute for Public Policy (WSIPP) was directed by the 2001 Washington State legislature to conduct long-term outcomes studies of clients of the Washington State public mental health system. In 2008, WSIPP reported the results of a 4-year study on 39,039 clients of the Washington State public mental health system. Based upon their analysis of Global Assessment of Functioning scale scores, the Institute report concluded that “5.7 to 12.5 percent of consumers in the study cohort [cohort: the group of individuals who are the subjects of a study] had a meaningful improvement in GAF scores during the period of service.” Significantly, the Institute stated, “Improvement levels did not appear to be related to utilization patterns.” In other words, those who received regular services did no better than those who received intermittent services.
