An introduction to CBT for Psychosis

Dr Harriet Mellotte

Tuesday 3 February 2026

Introduction

The workshop will provide an overview of Cognitive-Behavioural Therapy for psychosis (CBTp). Specifically, the application of CBT to the symptoms of auditory hallucinations and delusions will be addressed.  Topics such as engaging and assessing patients who present with psychosis; developing collaborative CBTp formulations; and applying appropriate CBT techniques will be covered.


The event will be equivalent to 2.3/4 hrs of CPD.

Content

Cognitive Behaviour Therapy for psychosis (CBTp) is an adaptation of standard CBT, informed by research into the psychological mechanisms underpinning psychotic symptoms, and tailored to accommodate the difficulties of people with psychosis. Cognitive models highlight that it is not unusual experiences themselves which are problematic, but their appraisal as external, personally significant and threatening. Maladaptive coping and safety behaviours also maintain distress and disability. CBTp aims to break these vicious cycles by helping people to understand their psychotic experiences, promote coping and self-regulation, and counter negative appraisals of self and difficulties.

CBTp includes a combination of elements and therapeutic activities and requires a very explicit focus on engagement, with a trusting relationship being a crucial foundation. The specific model used depends on what the primary difficulties are (e.g., delusions, voices, emotional difficulties). Each model emphasises the important role of appraisals of, and responses to, particular experiences, as well as a person’s previous experiences and their beliefs about themselves, the world, and others.

Successful implementation of CBTp involves both skilful application of therapy techniques and adherence to the underlying values and principles of offering hope and a recovery-oriented perspective; listening to and collaborating with the service user; and validating and supporting the ‘making sense’ process of the service user’s experiences.

Learning Objectives

• To develop knowledge and confidence in conducting a CBTp assessment
• To gain an understanding of formulations for individuals with psychosis
• To learn CBTp skills and techniques for changing delusions and voices

Training Modalities

The workshop will include: didactic content, stories from an individual with lived experience of CBTp, Q&A, live role play and video content.
