Note: Baseline was up to 2 months prior to randomization. Primary endpoint was on average 22.6 weeks after randomization (∼5 months), SD = 3.8 weeks. Follow-up during COVID-19−related restrictions and on average 111.5 weeks after randomization (∼2 years), SD = 17.3 weeks. There were no significant differences in baseline scores on the ABC-I or the APSI for the 2 intervention arms t(60) = −1.41, p = .165, and t(60) = −1.11, p = .272, respectively). ABC-I = Aberrant Behavior Checklist−Irritability subscale; APSI = Autism Parenting Stress Index.
