A novel methodology to develop low‐intensity psychological treatments

Abstract

Abstract Introduction Only a minority of individuals with mental health disorders receive specialist treatment. Low‐intensity psychological therapies, like guided self‐help, have the potential to bridge this global treatment gap. However, a systematic process for developing such therapies has not been proposed. This study proposes a systematic process for developing low‐intensity psychological treatments, exemplified by a low‐intensity Cognitive Behavioral Therapy (CBT) intervention for children and young people with eating disorders. Methods A systematic, three‐step process is presented. Firstly, a common elements analysis is conducted within the three pillars of evidence‐based practice (research, clinical expertise, and patient preferences). Secondly, a coding matrix is used to synthesize the common elements across these three pillars. Finally, patient and public involvement (PPI) feedback is incorporated for intervention refinement. Results Applying this methodology led to the development of an eight‐module, low intensity CBT intervention for children and young people with eating disorders, covering topics such as regular eating, body image, social media, and managing emotional triggers. Conclusion The intervention derived from this novel methodology is evidence‐informed and considers implementation into routine practice from the outset. This systematic approach to developing low intensity psychological interventions holds promise for closing the treatment gap irrespective of therapeutic orientation or disorder.
