Further validation of the Psycho-Social Well-Being Scale (PSWS) with community clients.

To monitor and evaluate the use of evidence-based approaches with mentally ill persons who abuse alcohol and other drugs, administrators, practitioners and evaluators will need to incorporate brief, reliable, and valid instruments into daily practice. The current two-part study provides further validation of the Psycho-Social Wellbeing Scale (PSWS), a multidisciplinary "debriefing tool" designed to capture and summarize data on clients' wellbeing from multiple sources in team-based community care. In the current investigation the PSWS was correlated with a number of valid instruments including the Brief Psychiatric Rating Scale, the Role Functioning Scale, the Social Functioning-12, the Alcohol Use Disorders Identification Test, the Alcohol Use and Drug Use Scales along with other important indices. Results show strong evidence of internal consistency, concurrent and discriminant validity with these criterion variables. Regression modeling demonstrates that the two main subscales (psychological and social wellbeing) add significantly to a model predicting substance abuse problems.
