About this study

This is a study comparing the benefits of two types of individual psychotherapy (cognitive-behavioral therapy for psychosis and supportive therapy) in symptomatic Veteran outpatients diagnosed with schizophrenia or schizoaffective disorder. Treatment lasted approximately 6 months, with outcome data on symptoms, functioning, and distress levels collected at baseline, post-treatment, and 6 months post -treatment follow-up.

Read the detailed description

This is a randomized controlled trial comparing 6 months of participation in one of two active treatments, cognitive-behavioral therapy for psychosis or supportive therapy in symptomatic Veterans diagnosed with schizophrenia or schizoaffective disorder who are still symptomatic. Assessments of clinical status and social functioning were obtained at baseline, end of treatment, and 6 month follow-up. We hypothesized that participation in the cognitive-behavioral therapy would lead to greater reductions in symptoms and distress about symptoms, and more improvements in social functioning.
