INTRODUCTION: Cognitive behavioural therapy for psychosis (CBTp) has been repeatedly shown to ameliorate psychotic symptoms. However, so far we have little understanding of the mechanisms of change in CBTp. In this study, we tested whether improved cognitive and behavioural efforts to manage taxing external or internal demands (=coping) constitute a mechanism of change in CBTp.
METHODS: Using data from a published trial for a secondary analysis, we tested whether the continuous symptomatic improvement of patients (n = 57) who received up to 45 sessions of CBTp and completed weekly self-assessments of symptoms (suspiciousness, individualised positive and negative symptoms, and individualised symptoms of depression) was mediated by preceding improvement in self-assessed coping using multilevel analysis. A reverse model in which symptom improvement predicted improved coping was also tested.
RESULTS: Continuous improvement in suspiciousness, negative symptoms, and depression over the course of CBTp was preceded by improvement in coping. Improvement in suspiciousness or positive symptoms did not predict subsequent improvement in coping, whereas improvement in negative symptoms and depression predicted subsequent improvement in coping.
CONCLUSION: Coping constitutes a mechanism of change, albeit to a different extent for different symptom clusters. Further research needs to explore how best to utilise this mechanism and optimise its integration with other active ingredients of CBTp to maximise therapeutic gain.
