Randomized Feasibility Pilot of an Executive Functioning Intervention Adapted for Children's Mental Health Settings.

The critical role of executive functioning in autism as well as the co-occurring mental health challenges common among autistic youth support to the immense value of interventions targeting executive functioning for enhancing mental health services for autistic children. The goal of the present study was to conduct a randomized feasibility trial of Unstuck and On Target, an executive functioning intervention, adapted for delivery in children's community mental health setting. Mental health therapists (n = 26) enrolled with participating autistic clients (n = 32) were randomized to receive training in and deliver the adapted Unstuck intervention or to deliver care as usual. We completed masked observational measures of Unstuck strategy use (fidelity) during recorded sessions of participating therapist-client dyads and collected measures of acceptability from participating clients and their caregivers. We also collected measures of pre-post changes in executive functioning and mental health symptoms. Therapists trained in Unstuck demonstrated significantly higher use of Unstuck strategies compared to usual care therapists. Caregivers and autistic clients perceive adapted Unstuck as highly acceptability and helpful. Autistic clients whose therapists were trained in adapted Unstuck demonstrated larger pre-post changes in executive functioning compared to usual care. Across all participating clients, changes in executive functioning were significantly related to changes in mental health symptoms. Finally, clients of therapists trained in adapted Unstuck demonstrated moderate improvements in overall mental health symptoms. The current study provides preliminary evidence of the feasibility and impact of Unstuck and On Target for children's community mental health settings.

Short report: A quantitative methodological review of participant characteristics in the literature testing mental health interventions for youth with autism spectrum disorder.

LAY ABSTRACT: Previous research has highlighted the importance of mental health treatment for autistic youth. In that research base, most studies focus on demonstrating the efficacy of a particular intervention with a sample of autistic youth. However, understanding the characteristics of samples used within these studies (i.e. demographics) is an important avenue for expanding this research to a more diverse, representative sample of autistic youth in community settings. As such, the current review examined and characterized participants included within mental health treatment research. We coded studies for various demographics among the youth sample, caregivers, and providers participants. Results indicated that while efforts have been made to increase diversity in research, very few studies including transition-aged youth, those identifying as female, and/or those identifying as non-Caucasian. Clinically, a few studies included youth with lower cognitive abilities and/or those with specific mental health problems (e.g. trauma and depression) or more than one co-occurring mental health conditions. Overall, our results highlight several critical gaps in our current evidence base regarding mental health treatment for autistic youth, including the limited clinical representativeness of both provider and child participants.

Brief Report: Emotional and Behavioral Problems Among Young Children with ASD: An Exploratory Study of ADOS E-Codes and Child Characteristics.

Emotional and behavioral problems (EBPs), such as anxiety, overactivity, and aggression, can influence the diagnosis of autism spectrum disorder (ASD). The gold standard diagnostic tool for ASD, the Autism Diagnostic Observation Schedule-Second Edition, includes three items ("E-codes") for EBPs that are frequently associated with ASD. Few empirical investigations have explored the use of E-codes. This study examined the relationship between E-codes and child characteristics (e.g., cognitive abilities, ASD symptom severity) in a sample of young children with ASD (N = 233). Findings indicated that E-codes positively correlated with ASD symptom severity and negatively associated with IQ. Symptom severity also significantly accounted for the variance in EBPs. Implications for ASD assessment as well as future research are discussed.
