Examining patterns of patient adherence to Cognitive Behavioural Therapy in chronic physical illnesses and comorbid mental health disorders: a scoping review protocol

Objective To examine the patient adherence patterns to Cognitive Behaviour Therapy (CBT) intervention in persons living with long term physical illness and co-occurring mental health conditions. Introduction Current literature on patient treatment adherence is mostly focused on the medical/pharmacological treatment or is disorder/ therapy specific and does not address co-occurring or comorbid mental health disorders with physical health disorders in general. The objective of this scoping review is to provide insights into adherence behaviours and patterns outside of pharmacological intervention focusing on psychotherapeutic intervention specifically Cognitive Behaviour Therapy (CBT) in persons living with long-term medical conditions with co-existing mental health disorders/ conditions. The results of the review will highlight different aspects of adherence to CBT including facilitating and impeding factors influencing adherence, and variations across comorbid mental and physical health conditions. These results will aid in developing targeted CBT interventions and strategies to improve adherence rates. Furthermore, identifying gaps in the existing literature will guide future research to optimise health outcomes in this population. Inclusion Criteria Using the Population, Concept, and Context (PCC) criteria, studies will be included if they reported on patient adherence patterns of CBT in persons living with chronic medical conditions and co-occurring mental health conditions. Methods The scoping review will follow the Joanna Briggs Institute (JBI) guidelines for scoping review and reported according to the PRISMA-ScR checklist. A systematic search of PubMed, CINAHL Plus (including full academic search, APA PsychInfo, and Medline), Scopus, Cochrane library, EMBASE, Google Scholar, and University College Cork (UCC) library’s one search platform will be conducted. The JBI standard data extraction tool will be tailored to the review objectives. The findings will be presented using a descriptive and narrative approach.
