Cognitive behavioural therapy (CBT) has become a widely used psychological approach for psychosis. This volume from the ISPS series focuses on a symptom-based approach, offering clinicians a framework for addressing individual psychotic symptoms.

Understanding CBT for Psychosis

CBT for psychosis (CBTp) is a psychological treatment designed to help individuals manage distressing psychotic symptoms. It is based on the idea that thoughts, feelings, and behaviours are interconnected, and that changing unhelpful patterns may alleviate distress. Some research suggests CBTp may reduce the severity of delusions, hallucinations, and negative symptoms, and may improve functioning. In some countries, clinical guidelines recommend it as a treatment option for psychosis.

The therapy relies on a collaborative therapeutic relationship. Techniques may include cognitive restructuring, behavioural experiments, and coping strategy enhancement. Typically delivered over 12–20 sessions, CBTp can be tailored to individual needs. The symptom-based approach, which this book emphasises, targets specific psychotic phenomena rather than a broad diagnosis, potentially enabling more precise interventions.

The Symptom-Based Approach

Rather than treating all psychotic symptoms uniformly, the symptom-based approach tailors interventions to the distinct nature of each symptom. For example, strategies for persecutory delusions may differ from those for auditory hallucinations. This method recognises that different symptoms may have unique cognitive and behavioural correlates, thus requiring specialised therapeutic strategies.

Key elements include detailed symptom assessment, formulation of maintaining factors, and selection of appropriate cognitive and behavioural techniques. Grounded in cognitive models that explain how delusions and hallucinations may persist, this approach aims to reduce the distress and disability associated with each symptom. Some research suggests CBTp may be effective in reducing symptom severity and preventing relapse, with meta-analyses indicating moderate effect sizes for positive symptoms. The symptom-based approach builds on this evidence by offering a more nuanced application of CBT principles, potentially enhancing outcomes.
