A review of the literature relating to psychological interventions and people with intellectual disabilities: issues for research, policy, education and clinical practice.

The aim of this review is to identify and analyse the published evidence base and wider literature in relation to psychological interventions for adults with intellectual disabilities. The review suggests that the evidence base regarding psychological interventions is sparse yet growing, and if the therapeutic approaches are modified and adapted to meet the distinct needs of people with intellectual disabilities these may be life enhancing. The lack of access to psychotherapies for people with intellectual disabilities has led to their exclusion from mainstream research, thereby limiting the evidence base on effective interventions and treatment approaches.
