Effectiveness of behavioral parent training in the outpatient setting for preschoolers at risk for ADHD

Abstract

Abstract In 2019, the American Pediatric Association released updated guidelines regarding assessing and treating attention-deficit/hyperactivity disorder (ADHD). These guidelines prescribe behavioral parent training (BPT) as the first line of treatment for preschool-aged children with ADHD symptomatology. However, there are few studies documenting the effectiveness of BPT administered in real-word settings, outside the context of controlled research trials. Further, many available BPT programs are lengthy and costly. Here we investigate the effectiveness of an 8-session group-based BPT, previously shown effective in school-aged children with ADHD, in an outpatient clinic. Ratings of parental confidence, child impairment, number and severity of non-compliance in multiple situations, and ADHD and oppositional symptoms, were collected from 132 parents of preschoolers at risk for ADHD before and after the BPT groups. Improvements with a large effect size were observed for overall severity of impairment and parental confidence ratings. Improvements with a moderate effect size were observed for academic progress, severity of non-compliance, and ADHD symptom ratings. Small effect sizes were observed for reduced impairment in family functioning, peer and parental relationships, and self-esteem, frequency of non-compliance, and oppositional defiant symptom ratings. Together these findings support the effectiveness of a BPT program to treat preschool ADHD and ADHD-like behaviors that is accessible to families and clinicians.
