Cognitive-Behavioral Therapy for Irritability in Children With Autism Spectrum Disorder and Intellectual Disability

Study Overview
=================
Brief Summary
-----------------
In addition to the core symptoms, children and adolescents with Autism Spectrum Disorder (ASD) often exhibit disruptive behavior problems including irritability, tantrums, noncompliance, and aggression. The purpose of this study is to investigate cognitive-behavioral therapy (CBT) for disruptive behavior in children with autism spectrum disorders and intellectual disability. This pilot study will include children with ASD and IQ between 55 and 85 in an open study of CBT. CBT is modified in this study to reduce complexity of activities during therapy sessions but retains all key elements and principles of CBT. Assessments of irritability and disruptive behavior will include clinical interviews, parent ratings and child self-report measures. Study participants will be asked to complete functional magnetic resonance imaging (fMRI) to evaluate biomarkers of social perception and emotion regulation before and after CBT.

Detailed Description
-----------------
Children with ASD share common symptoms in the core domains of social reciprocity, communication, and repetitive behaviors. In addition to the core symptoms, 50 to 70 percent of children with ASD often exhibit disruptive behavior problems including irritability, tantrums, noncompliance, aggression and self-injury. In this open pilot study expands clinical research on CBT for irritability to children with autism and mild cognitive impairment. CBT consists of individual weekly sessions dedicated to teaching children to recognize situations that may lead to frustration and to build coping skills for dealing with frustration in socially appropriate ways. Recent research as well as clinical reports suggest that children with mild intellectual disabilities (IQ between 55 and 85) can also benefit from CBT. The intervention is modified to reduce complexity of activities during therapy sessions but retains key elements and principles of CBT. Thus, the modified version of CBT is referred to as Principles-Based Cognitive Behavior Therapy for Irritability in Autism or PB-CBT for short. Subjects in this study will receive a comprehensive evaluation of ASD and associated psychopathology. Irritability and related disruptive behaviors will be rated on weekly basis to utilize a single-subject approach to data analysis. Children will be asked to participate in functional magnetic resonance imaging (fMRI) with tasks of social perception and emotion regulation before and after CBT. The purpose of the fMRI portion of the study is to evaluate feasibility of fMRI as an outcome measure in studies of behavioral interventions for children with ASD and intellectual disability.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cognitive-Behavioral Therapy<br>CBT is a behavioral intervention where children are taught various skills for coping with frustration and parents are taught various strategies for managing situations that can be anger-provoking for their child. | Behavioral: Cognitive-Behavioral Therapy<br>* CBT is a behavioral intervention that consists of 12 60- to 90-minute-long weekly sessions. A modified, principles-based form of CBT will be used in this study to reduce complexity of activities during therapy sessions while retaining all key elements and principles of CBT.<br>Other: Functional magnetic resonance imaging (fMRI)<br>* Functional magnetic resonance imaging (fMRI). There will be two fMRI visits, 60 to 90 minute each, one before and the other after CBT. fMRI is a technique that uses magnetism to measure activity of the brain as participants perform simple tasks such as pressing the button in response to pictures. During this study, children will be asked to look at pictures of objects and press or not press the button in response to specific instruction. Participants will also look at pictures of faces and light-point displays depicted biological motion. fMRI is used as an outcome measure to explore if change in irritability is associated with change in brain responses to these tasks during fMRI.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Modified Overt Aggression Scale (MOAS) | Modified Overt Aggression Scale (MOAS) is a 16-item scale that reflects the frequency and severity of incidents of aggressive behavior | Weekly - up to 20 weeks | 
| Aberrant Behavior Checklist - Irritability Scale (ABC-I) | The ABC-I is a 15-item parent rating of irritability that has been commonly used in clinical trials in children with ASD. | Weekly - up to 20 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Home Situations Questionnaire (HSQ) | HSQ is a parent-rated measure of noncompliance in children with ASD | baseline | 
| Home Situations Questionnaire (HSQ) | HSQ is a parent-rated measure of noncompliance in children with ASD | endpoint (16 weeks) |
