Crisis-focused Cognitive Behavioural Therapy for Psychosis (CBTp) vs Treatment as Usual in Acute Mental Health Inpatient Settings (The CRISIS Study): Protocol For a Feasibility Randomised Controlled Trial

Abstract

\n Background\n\nCognitive Behavioural Therapy for psychosis (CBTp) is a psychological therapy which should be offered during the acute phases of psychosis. However, few research studies have examined the efficacy of CBTp interventions specifically adapted for the acute mental health inpatient context with most research trials being conducted with white European community populations.\nAims\n\nThe aim of this study is to conduct a feasibility Randomised Controlled Trial (RCT) of a crisis-focused CBTp intervention adapted for an ethnically diverse acute mental health inpatient population. The study will examine the feasibility of undertaking the trial, the acceptability and safety of the intervention, and the suitability of chosen outcome measures. This will inform the planning of a future, fully powered RCT.\nMethods\n\nA single-site, parallel group, feasibility RCT will be conducted examining the intervention. Drawing on principles of coproduction, the intervention has been adapted in partnership with key stakeholders; service users with lived experience of psychosis and of inpatient care (including those from ethnic minority backgrounds), carers, multidisciplinary inpatient clinicians, and researchers. Sixty participants with experience of psychosis and in current receipt of acute mental health inpatient care will be recruited. Participants will be randomly allocated to either the crisis-focused CBTp intervention or Treatment as Usual (TAU).\nDiscussion\n\nFindings of this feasibility RCT will indicate whether a larger multi-site RCT is needed to investigate the efficacy of the intervention. If the initial results demonstrate that this trial is feasible and the intervention is acceptable, it will provide evidence that a full-scale effectiveness trial may be warranted.\nTrial registration:\n\nThis trial has been prospectively registered on the ISRCTN registry (ISRCTN59055607) on the 18th February 2021 https://www.isrctn.com/ISRCTN59055607
