Cognitive Behavioral Therapy (CBT) is among the most effective psychotherapy approaches for a wide range of presenting problems. Modified CBT is also a promising practice in the treatment of mental health challenges for persons with Intellectual and Developmental Disabilities (IDD). Many people question the effectiveness of an approach that focuses squarely on cognition for a group of people with cognitive impairments. While this concern may be valid for some individuals with IDD, many others have the requisite cognitive ability to be successful if some reasonable accommodations are made. Modified CBT may offer an alternative to highly restrictive forms of treatment for many people with significant behavioral and mental health challenges. Because of its focus on the internal thoughts and feelings and ways to enhance personal effectiveness, it also humanizes the person with IDD in a way that other treatments do not. The goal of this course is to provide information and tools for CBT therapists so that they can modify their approach to make it more effective for persons with IDD. By using vignettes and interactive exercises, therapists will acquire some basic skills they can apply to the use of CBT with persons with IDD.
