title: A test of the reliability and validity of the Multnomah Community Ability Scale.
abstract: Previous research shows that the Multnomah Community Ability Scale (MCAS) total score is reliable and has predictive validity. This study evaluates the MCAS total and sub-scale scores on a sample of 1,250 outpatient mental health clients in Washington State. The MCAS sub-scales are reliable, and there is evidence for their concurrent validity. However, the factor structure of the MCAS only partially replicated the hypothesized sub-scales, and the authors recommend that sub-scales as currently constructed not be used as performance indicators. If only the total MCAS is of interest to users, the authors recommend using the single-item SOFAS rather than the 17-item MCAS.
