Abstract

The present study examines the impact of group based cognitive behavior therapy (CBT) for drug resistant auditory hallucinations, or voices. In particular it assesses treatment effect on beliefs in a voice’s omnipotence and control. Twenty-two participants entered one of five 8-session CBT groups. Measures of omnipotence, control, process measures, and symptoms of anxiety and depression were completed at assessment, and first and last group sessions. The groups achieved a significant reduction in conviction in beliefs about omnipotence (df 2, P=0.002) and control (df 2, P=0.001). There were no affective changes. Certain participants showed important spontaneous changes in behavior. Process measures suggested that participants valued the groups and benefited from them. These results are promising and the treatment may prove a useful addition to existing psychological interventions.
