About this trial
The purpose of this open label trial is to examine the preliminary feasibility, acceptability, and effectiveness of a 12-week behavioral intervention program (1 hour/week) to treat insistence on sameness (e.g., difficulty tolerating changes in routine) in youth with autism spectrum disorder (ASD). Treatment will be delivered via secure telemedicine platform and consist of a combination of parent-training and parent-mediated intervention with the child.

Treatment groups
Trial outcomes
Primary outcomes
Change from Baseline in Insistence on Sameness Subscale of the Dimensional Assessment of Restricted and Repetitive Behaviors (DARB).
DARB insistence on sameness subscale scores measure insistence on sameness with higher scores indicating greater intensity of insistence on sameness. \[Score Range: 0-76\]
Secondary outcomes
Change from Baseline on Blinded Clinician Ratings of Clinical Global Impression Scale, Severity and Improvement Ratings.
Score Range: 1 = normal, not at all ill; 7 = among the most extremely ill patients; 1 = very much informed since the initiation of treatment; 7 = very much worse since the initiation of treatment.
Change from Baseline in Parent-Rated Emotion Dysregulation on the Strengths and Difficulties Questionnaire Dysregulation Profile (SDQ-DP) during treatment.
SDQ-DP indexes broad emotion dysregulation with higher scores indicating greater intensity of emotion dysregulation. \[Score Range: 1-27\]
Change from Baseline in Parent-Rated Behavioral Inflexibility as captured by the Behavioral Inflexibility Scale.
The BIS includes 38 items with higher scores indicating greater irritability. \[Score range: 0-190\].
Change from Baseline in Ritualistic/Sameness Subscale of Repetitive Behavior Scale-Revised (RBS-R).
Higher scores indicate higher levels of RRBs. \[43 items, 12 in sameness domain\]
Other outcomes
Social Validity Measures
Caregivers will complete a survey and interview post-intervention to assess feasibility, acceptability, and satisfaction with the intervention.
