This study investigated the effects of a structured group reading program on clinical status, disability, psychosocial functioning, and cognitive functioning in 41 hospitalized patients with psychosis. Patients were randomly assigned to either the reading group or a control group. Evaluations were conducted at baseline and 6 months. The reading group showed statistically significant improvements in cognitive and psychosocial functioning, and reduced disability, compared to the control group. The reading activities were perceived as useful, interesting, and pleasant by patients. The study suggests that structured group reading programs may be an effective psychosocial rehabilitation tool for patients with psychosis.
