Cognitive-Behavioural Therapy for Command Hallucinations and Intellectual Disability: A Case Study

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

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.

A review of the frequency and nature of adaptations to cognitive behavioural therapy for adults with Intellectual Disabilities

BACKGROUND

There is increasing evidence that cognitive behavioural therapy (CBT) can be effective for people with intellectual disabilities. The aim of this review was to report the nature and frequency of adaptations reported in studies of CBT for people with intellectual disabilities.

METHOD

This review updated and extended a previous review by (Whitehouse et al. 2006, J Appl Res Intellect Disabil, 19, 55), which used a framework of adaptations developed by (Hurley et al., 1998, J Dev Phys Disabil, 10, 365). Adaptations included simplification, language, activities, developmental level, use of directive style, flexible methods, involve caregivers, transference/countertransference and disability/rehabilitation approaches. A search identified peer-reviewed papers that reported individual CBT informed psychological interventions for people with an Intellectual Disability.

RESULTS

The search identified 23 studies which met the inclusion criteria for review. Studies reported the majority of the categories of adaptation described by (Hurley et al., 1998, J Dev Phys Disabil, 10, 365).

CONCLUSIONS

The results suggest that the framework of adaptations needs further development to increase sensitivity in identifying and categorizing adaptations of CBT. Increased, systematic reporting of adaptations to studies of CBT with people with intellectual disabilities is recommended.

Psychological therapies for people with intellectual disabilities: a systematic review and meta-analysis

The aim of this study was to evaluate the efficacy of psychological therapies for people with intellectual disabilities (IDs) through a systematic review and meta-analysis of the current literature. A comprehensive literature search identified 143 intervention studies. Twenty-two trials were eligible for review, and 14 of these were subsequently included in the meta-analysis. Many studies did not include adequate information about their participants, especially the nature of their IDs; information about masked assessment, and therapy fidelity was also lacking. The meta-analysis yielded an overall moderate between-group effect size, g=.682, while group-based interventions had a moderate but smaller treatment effect than individual-based interventions. Cognitive-behaviour therapy (CBT) was efficacious for both anger and depression, while interventions aimed at improving interpersonal functioning were not effectual. When CBT was excluded, there was insufficient evidence regarding the efficacy of other psychological therapies, or psychological therapies intended to treat mental health problems in children and young people with IDs. Adults with IDs and concurrent mental health problems appear to benefit from psychological therapies. However, clinical trials need to make use of improved reporting standards and larger samples.

Access all areas: creative adaptations for CBT with people with cognitive impairments – illustrations and issues

Policy and legislation requires clinicians and services to address diversity and equalities including disability. Currently, practice, training and research do not do this adequately. This paper outlines why adapted CBT is important and presents some evidence to increase accessibility for people who have cognitive impairments, learning disabilities and/or neurodevelopmental disorders. It demonstrates how CBT can be made accessible through clinical examples using traditional, adapted and personalized assessment and intervention materials. Implications and recommendations are identified.
