Evidence-Based Treatments for Comorbid Autism Spectrum Disorders

Abstract

This chapter provides an overview of evidence-based treatments designed for individuals with comorbid diagnoses of autism spectrum disorder (ASD) and intellectual disability (ID). Common symptoms of ASD that are often apparent in early childhood are difficulties with social interaction, speech delays, repetitive behaviors, and limited interests. When individuals have a comorbid diagnosis of ASD and ID, frequently referred to as “low-functioning autism,” many of the typical treatments that are used for these individuals require modifications. The categories of evidence-based treatments highlighted in this chapter include behavioral and cognitive-behavioral interventions, naturalistic interventions, early interventions, social skills training, language training, as well as parent and peer interventions. The treatments discussed in this chapter have traditionally exhibited effectiveness for school-aged children, but more research could support their appropriateness for youth and adult populations in the future.
