Empirically supported psychological treatments: The challenges of comorbid psychiatric and behavioral disorders in people with intellectual disability

Abstract

This paper reviews the current state of knowledge on psychological interventions with empirical evidence of efficacy in treating common psychiatric and behavioral disorders in people with intellectual disability (ID) at all stages of their life. We begin with a brief presentation of what is meant by psychiatric and behavioral disorders in this population, along with an explanation of some of the factors that contribute to the increased psychosocial vulnerability of this group to present with these problems. We then conduct a review of empirically supported psychological therapies used to treat psychiatric and behavioral disorders in people with ID. The review is structured around the three generations of therapies: Applied behavior analysis (e.g., positive behavior support), cognitive behavioral therapies (e.g., mindfulness-based cognitive therapy), and contextual therapies (e.g., dialectical behavior therapy). We conclude with some recommendations for professional practice in the fields of ID and psychiatry.
