Substance related disorders are common in individuals with severe and persistent mental illness. The effects of substance use in patients with comorbid mental illness are varied and include both increases and decreases in psychiatric symptoms. Behavioral assessment of substance use provides a useful framework for identifying the interdependence of substance use and psychiatric symptoms. One important component of behavioral assessment is the analysis of antecedents and consequences. This paper describes the use of this approach in the assessment and treatment of a man with a multiple substance-related disorder and major depressive disorder with psychotic features. Eighteen-month outcome data are reported, and the utility of conducting a behavioral assessment for treatment planning and ongoing treatment evaluation is discussed.
