Arms Assigned Interventions
Experimental: Cognitive Behavioral Therapy for Psychosis (CBTp)
approximately 6 months of weekly individual manualized cognitive-behavioral psychotherapy for psychosis in which participants set personal goals, identify problematic/ illness-related beliefs and experiences that may interfere with achieving those goals, evaluate the data supporting those beliefs, and then modify the beliefs or behavior as warranted by the data to make progress on those goals.
Behavioral: Cognitive Behavioral Therapy for Psychosis (CBTp)
approximately 20 sessions of individual manualized psychotherapy in which participants are taught to evaluate the data supporting beliefs that may interfere with recovery
Active Comparator: Supportive Therapy (ST)
approximately 6 months of weekly manualized supportive psychotherapy to promote a strong alliance between the therapist and the participant in order to provide a safe place to discuss issues pertaining to the participants' lives and concerns
Behavioral: Supportive Therapy (ST)
approximately 20 sessions of manualized psychotherapy to promote a strong alliance between the therapist and the participant in order to provide a safe place to discuss issues pertaining to recovery

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.
