Group mindfulness-based intervention for distressing voices: a pragmatic randomised controlled trial

Group Person-Based Cognitive Therapy (PBCT) integrates cognitive therapy and mindfulness to target distinct sources of distress in psychosis. The present study presents data from the first randomised controlled trial inves- tigating group PBCT in people distressed by hearing voices. One-hundred and eight participants were randomised to receive either group PBCT and Treatment As Usual (TAU) or TAU only. While there was no significant effect on the primary outcome, a measure of general psychological distress, results showed significant between-group post-intervention benefits in voice-related distress, perceived controllability of voices and recovery. Participants in the PBCT group reported significantly lower post-treatment levels of depression, with this effect maintained at six-month follow-up. Findings suggest PBCT delivered over 12 weeks effectively impacts key dimensions of the voice hearing experience, supports meaningful behaviour change, and has lasting effects on mood.
