This trial examined stepped-care cognitive-behavioral treatment (CBT) among 96 autistic youth with co-occurring anxiety. Step 1 included an open trial of parent-led, therapist-guided bibliotherapy. Step 2 was family-based CBT for those who did not respond to Step 1 or maintenance for those who did. Eighteen participants (28%) who completed Step 1…

The purpose of this literature review was to provide a comprehensive summary of the relationship between Autism Spectrum Disorder (ASD) and Avoidant/Restrictive Food Intake Disorder (ARFID). Eight research studies published between the years 2012 and 2022 were included in the review. The studies examined various symptoms, risk factors,…

We used real world data to summarize comorbidities and interventions among patients newly diagnosed with autism spectrum disorder (ASD). Data were derived from two claims-based US healthcare databases; Medicaid and Optum to construct a retrospective cohort of 36,000 patients. Attention-Deficit-Hyperactivity-Disorder (ADHD) was the most common…

Little is known about the effect that co-occurring psychiatric conditions may have on treatment response to CBT for children with ASD and anxiety. The present study examined the relationship between co-occurring psychiatric diagnoses and response to CBT for anxiety in…

This pilot randomized controlled trial aimed to determine the feasibility of adapted DBT for adults with intellectual disabilities and co-morbid psychiatric disorders in the community. Methods: An adapted…

In this study we tested the usability, feasibility, social validity, and effectiveness of Engaged Learners, a behavior support program designed to be integrated into small group reading interventions. Participants included eight Grade 3-5 students with co-occurring reading difficulties and inattention. A concurrent multiple-baseline design was…

Anxiety/obsessive-compulsive disorders are common among youth with autism spectrum disorder (ASD). Two versions of cognitive behavior therapy (CBT) are effective, with some advantage for a personalized, adapted version. This study evaluated predictors and moderators of standard CBT and adapted CBT. Youth (N = 167) ages 7-13 were randomized to…

However, it is not clear how actively families are involved when people with intellectual disabilities and challenging behaviors are living in out-of-home care. This scoping review explored the frequency and type of…

This review outlines issues…

Obsessive-compulsive disorder and autism spectrum disorder commonly co-occur. Adapted cognitive behavior therapy for obsessive-compulsive disorder in adults with autism spectrum disorder has not previously been evaluated outside the United Kingdom. In this study, 19 adults with obsessive-compulsive disorder and autism spectrum disorder were…

The aim of this study was to examine a new community-based, clinical mental health service for young people (12-25 years) with co-occurring ID and…

Preschoolers with elevated anxiety symptoms are at high risk not only of developing more severe mental health disorders in later life but are also apt to respond more poorly to intervention if they present with comorbid disruptive behavior. Because early signs of anxiety disorders may not be recognized as such in preschool settings, many children…
