Manualized Group Cognitive-behavioral Therapy for Social Anxiety in First Episode Psychosis

Social anxiety represents one of the most prevalent comorbid conditions in schizophrenia and related psychosis. Schizophrenia patients with comorbid social anxiety often exhibit impaired social functioning, an increased risk for relapse, and higher rates of suicide. Social anxiety is a treatable condition but has, in the context of psychosis, received only scant attention thus far. There is strong evidence that cognitive-behavioral therapy (CBT) for the treatment of social anxiety is very effective, whether it is delivered individually or in a group setting, and studies have shown that a group setting is more effective than individual therapy. Providing a CBT intervention for social anxiety represents an effective way to empower people with this illness. The investigators have conducted a preliminary study using an uncontrolled design to assess feasibility and initial benefits of a new manualized group CBT intervention for social anxiety specifically adapted for people with psychosis. The investigators observed a significant reduction in social anxiety symptoms across three groups of first episode psychosis (FEP) participants (n=29) following completion of this 13-week intervention, and observed large effect sizes confirming a significant positive influence of this intervention. The investigators now propose to conduct a randomized controlled trial to fully assess the efficacy of this intervention. The main objective of this research proposal is to contrast the impact of a CBT intervention for the treatment of social anxiety in first episode psychosis with another control condition involving computer assisted cognitive remediation therapy (CACRT). Both interventions will be offered in a group setting, and will therefore have the exact same parameters. A secondary objective of this study is to examine the impact of reduced social anxiety on measures of clinical and functional outcome. For this trial, 120 patients with recent onset psychotic disorder (defined as wit
