ABSTRACT
This chapter reviews the evidence for the effectiveness of adapted psychological interventions for people with intellectual disabilities who display behaviours that may contravene the law, particularly in relation to inappropriately expressed anger and sexually harmful behaviours. It focuses on the evidence for the effectiveness of cognitive-behavioural approaches mainly in relation to group work, where the best evidence exists for efficacy. The chapter provides some suggestions for therapeutic provision that would help provide appropriate assistance to offenders in community settings to support the development of Transforming Care in England, as an example. It discusses a series of important adaptations that can be made to traditional cognitive-behavioural interventions for this group to make them more accessible to people with intellectual disabilities. Adapted multi-component cognitive-behavioural treatments have also been used as the basis for group evaluations. Many programmes that are not adapted and take a cognitive or behavioural approach rely heavily on written materials to support therapeutic and psycho-educational approaches.
