Cognitive Behavioral Social Skills Training for Youth at Risk of Psychosis

Schizophrenia and other psychotic disorders are serious and debilitating mental illnesses that incur substantial suffering for patients and major challenges to the investigators health care and legal systems. The prodrome is the period prior to onset of psychosis when functional decline and clinical symptoms gradually emerge. The presence of a clinical high-risk (CHR) syndrome in young adults is associated with heightened risk (25-35%) for the later development of psychosis, and for those who do not necessarily go on to develop a psychotic illness, research has suggested that the majority continue to have fluctuating subthreshold symptoms and poor social and role functioning. There are no specific treatments to help with these functional difficulties. However, recent findings suggest that in people with schizophrenia, Cognitive Behavioral and Social Skills Training (CBSST) leads to significantly greater increase in the frequency of social functioning activities compared to treatment as usual or goal-focused supportive therapy, and preliminary data suggest CBSST is a feasible treatment for CHR. This proposal is a competitive application for a three-site, longitudinal study aimed at testing the effectiveness and feasibility as well as mediators and mechanisms of action of a manualized CBSST intervention that will target functional difficulties associated with clinical risk states for psychosis. The goals are 1) to examine whether CBSST compared to a placebo intervention (psychoeducation) matched for group involvement and therapist time improves functioning in youth at CHR and 2) to determine whether reduction in defeatist beliefs and improvement in social competence mediate change in psychosocial functioning in CHR youth in the CBSST. In this single-blind randomized 2-arm trial participants will be randomized to one of two treatments: CBSST, an 18-week group comprised of three modules; 1) Cognitive Skills; 2) Social Skills; and 3) Problem Solving, or a psychoeducation
