Adapting cognitive behaviour therapy for people with intellectual disabilities: an overview for therapist working in mainstream or specialist services

Abstract

Abstract This paper is an introduction to adaptations to make cognitive behaviour therapy (CBT) more accessible to people with intellectual disabilities. It is intended to inform therapists who may work with people with intellectual disabilities in mainstream services. The paper describes adaptations that consider neuropsychological processes, such as memory, and executive functions, such as planning, problem solving and self-regulation, and identifies that these factors are not unique to people with intellectual disabilities. We describe adaptations based on a review of literature describing CBT for people with intellectual disabilities (Surley and Dagnan, 2019) and draw on clinical experience to give examples of adaptations where possible. The paper particularly emphasises the generalisability of adaptations used with people with intellectual disabilities to therapy with wider populations and suggests that CBT therapists working in mainstream services will have the skills to be able to adapt therapy for people with intellectual disabilities. Key learning aims (1) To overview the evidence base supporting the use of CBT with people with intellectual disabilities. (2) To describe the epidemiology of intellectual disability and discuss its implications for the generalisability of adaptations discussed in this paper. (3) To describe a range of adaptations to make CBT more accessible people with intellectual disabilities. (4) To consider whether such adaptations are part of the skill set of CBT therapists mainly working with people without intellectual disabilities.
