Pediatric Physical Therapy, 30(4), 326–334. https://doi.org/10.1097/PEP.0000000000000534.Purpose: To assess a motivational interviewing (MI) intervention to improve moderateto-vigorous physical activity (MVPA) in adolescents with congenital heart disease. Design: Pilot randomized controlled trial. Methods: Intervention participants received one-on-one telephone-based adapted MI sessions over 3 months. Outcomes were acceptability, change mechanisms (stage of change and self-efficacy), and limitedefficacy (PA, fitness and quality of life). Findings: 36 (66.7%) patients (50.0% male; 15.1±1.5 years) were randomized. Intervention participants completed 4.2±1.2/6 MI sessions, with no improvements in the high self-efficacy or stage of change observed (p>0.05). Overall, participants accumulated 47.24±16.36 minutes of MVPA/day, and had comparable outcomes to healthy peers (except for functional capacity). There was no significant difference in change in any outcome by group. Conclusions: The intervention was acceptable, but effectiveness could not be determined due to the nature and size of sample. Clinical Relevance: Pediatric cardiac rehabilitation remains the sole effective intervention to increase MVPA in this population.enCongenital heart diseaseMotivational interviewingPhysical activityArticle
