Validation of the Behavioral Activation for Depression Scale in Individuals With Substance Use Disorders

This observational study evaluates the psychometric properties of the Behavioral Activation for Depression Scale (BADS) in individuals with substance use disorders. The study examines the scale's internal structure, reliability, and validity using data from 289 participants who completed the BADS. External and incremental validity analyses were conducted in a subsample of 127 participants for whom additional clinical measures were available, including assessments of symptom severity, anxiety, impulsivity, and anger expression. This approach reflects the availability of complete data for each analytic component and allows for a comprehensive evaluation of the BADS in a clinical population.
