During the COVID-19 pandemic, schools rapidly changed from in-class instruction to remote learning. Parent involvement and management of the home learning situation was greatly emphasized, and this presented challenges and opportunities for parents of children with attention-deficit/hyperactivity disorder (ADHD). There was an urgent need for effective parent support in the home learning situation, particularly for parents of youth with ADHD. The current study implemented a behavioral parent training (BPT) program, an evidence-based intervention for childhood ADHD, modified to target home learning and be delivered via telehealth. The intervention was evaluated in a multiple baseline trial across families of youth with ADHD (n = 3). The primary outcome was daily, parent-reported academic engagement during home learning. Parents also completed daily ratings of their child's respectful and disruptive behavior, and remote, home observations of academic tasks were recorded at baseline and post-treatment. Based on visual analysis of baseline, treatment and post-treatment daily ratings, two of the three participants had a positive response to treatment indicated by improved academic engagement. These findings provide preliminary support for the home-learning, telehealth-delivered BPT program in supporting families during the COVID pandemic.
