Brief Cognitive Behavioral Therapy for Depression and Anxiety in Patients with Schizophrenia in Psychiatric Home Nursing Service: Pilot Randomized Controlled Trial.

This pilot randomized controlled trial (RCT) aimed to explore whether depression and anxiety could be reduced by psychiatric home nursing supporters offering brief cognitive behavioral therapy for psychosis (CBTp) at home, using a workbook for patients with schizophrenia. Eighteen patients with schizophrenia treated in a psychiatric home nursing service were randomly assigned to two groups: one group received CBTp in addition to usual care (TAU + CBTp group; n = 9) and the other received only usual care (TAU group; n = 9); two patients were excluded due to hospitalization or withdrawal of consent. Eight weekly CBTp sessions were conducted; anxiety/depression, quality of life, self-esteem, and overall functioning were assessed at baseline, week 9, and week 13. There was no significant difference in the primary and secondary evaluations. The effect size was 0.84 for primary evaluation indicating a large effect. This study showed that nurses and occupational therapists can provide CBTp in psychiatric home nursing for patients with schizophrenia to potentially alleviate anxiety and depression compared to standard psychiatric home nursing service alone. Therefore, larger RCTs with larger sample sizes are recommended.
