Resiliency Intervention for Siblings of Children With Autism Spectrum Disorder: A Randomized Pilot Trial

BACKGROUND /OBJECTIVES: Neurotypical siblings (NT sib-lings) of children with autism spectrum disorder (ASD) are at elevated risk for emotional distress and adjustment problems. Resiliency is the ability to cope and adapt with ongoing stressors. We conducted a randomized waitlist-controlled pilot trial to examine the feasibility, acceptability, and preliminary efficacy of an adapted virtual mind-body resiliency group intervention for teen NT siblings of children with ASD.METHODS: We modified the Stress Management and Resiliency Training-Relaxation Response Resiliency Program for NT siblings of children with ASD (SibChat). We randomly assigned teens (aged 14-17) to immediate intervention (IG) versus waitlist control (WLC). The intervention included eight 60-minute weekly video conference group sessions. We assessed feasibility (enrollment, attendance, and retention) and acceptability (post treatment survey and weekly relaxation response practice). We explored group differences in pre-post change scores for 1) stress coping (Measure of Current Status-A) and 2) resiliency (Current Experiences Scale) using independent samples t tests and effect size calculations.RESULTS: We enrolled 83% of screened eligible teens. A total of 90% IG and 75% WLC participants attended at least 6/8 sessions. Among IG participants who completed the post treatment survey, 79% reported practicing relaxation response exercises at least "a few times a week". Comparing change in baseline to time 1, the IG showed better relative changes than the WLC group in stress coping (d = 0.60) and resiliency (d = 0.24).CONCLUSIONS: Our pilot trial showed promising feasibility, acceptability, and preliminary efficacy of SibChat on at least one of the 2 primary outcomes supporting further testing of the SibChat intervention.CLINICAL TRIAL REGISTRATION: US National Library of Medicine.
