Measure
Cognitive-behavioral Therapy for Psychosis (CBTp)
approximately 6 months of weekly individual manualized cognitive-behavior for psychosis psychotherapy in which participants are taught to set personal goals, identify problematic 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. CBTp: approximately 20 sessions of individual manualized psychotherapy in which participants are taught to evaluate the data supporting beliefs that may interfere with recovery
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' life and concerns 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
