Official Title: Functional Behavior-based Cognitive-Behavioral Therapy for Obsessive Compulsive Behavior in Children With Autism Spectrum Disorder: A Randomized Controlled Trial

Brief Summary: Individuals with high functioning autism spectrum disorder (ASD) frequently experience obsessions and/or compulsions that are similar to those specified in Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) criteria for obsessive compulsive disorder (OCD). However, little research exists on effective interventions for OCD symptoms (referred to as OCBs) in ASD. In a randomized controlled trial, a manualized functional behavior-based cognitive-behavior therapy (Fb-CBT) consisting of traditional CBT components (psychoeducation and mapping, cognitive-behavioral skills training, exposure, and response prevention) as well as function-based behavioral assessment will be evaluated. Participants will be assigned randomly to Fb-CBT or treatment as usual (TAU). Primary and secondary outcome measures will be used to evaluate the efficacy of the treatment, and will be administered at pre and post-intervention as well as six month follow-up.

Sponsor: Tricia Vause

Current Primary Outcome:

  • Change in Repetitive Behavior Scale (RBS_SCR) [ Time Frame: Assessment occurred at baseline and 2 weeks following end of treatment, as well as at follow-up (6 months following the cessation of treatment) ]
    The RBS is a 43-item parent rating measure of repetitive behavior. It is comprised of a four-point Likert scale ranging from (0) behavior does not occur, to (3) behavior occurs and is a severe problem . The RBS_SCR scale specifically focusses on the assessment of sameness, compulsive, and ritualistic behaviors
  • Change in Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) [ Time Frame: Assessment occurred at baseline and 2 weeks following end of treatment ]
    A 10-item, semi-structured interview used to assess symptom severity for children ages 6 through 17 years. Each item is rated on a 5-point ordinal scale from 0 (none) to 4 (extreme)' For the purpose of this study, only the 5-item Compulsion score was used pre and post-treatment.


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Change in Repetitive Behavior Scale 100 (RBS_100) [ Time Frame: Assessment occurred at baseline and 2 weeks following the end of treatment, as well as at follow-up (6 months following the cessation of treatment) ]
    The final item on the RBS-R asks caregivers to rate on a scale from 1 to 100 how much OCBs affect the child and the people around them (1 is not a problem to 100 is as bad as can be imagined; Bodfish et al., 1999).
  • Change in The child Obsessive-Compulsive Impact Scale-Revised (COIS-R) [ Time Frame: Assessment occurred at baseline and 2-weeks following the end of treatment, as well as at follow-up (6 months following the cessation of treatment) ]
    A 33-item, parent-report questionnaire that assesses OCD-related impairment in various areas of the child's life, including school, social, and home/family activities. For each item, the parent rates the child's level of impairment on a 4-point Likert scale from 0 (not at all) to 3 (very much).
  • Parent OCB Rating Scale. [ Time Frame: Scale was completed by parents at baseline, each day throughout the 9-week treatment period, and at follow-up (6 months following the cessation of treatment) ]
    A Likert-type scale ranging from 1 (desired post-treatment levels of OCBs) to 3 (partial improvement from pre-treatment levels) to 5 (pre-treatment levels of OCBs) was used by parents to rate OCBs.


Original Secondary Outcome: Same as current
