RESEARCH REPORTS

Purpose: To assess a motivational interviewing (MI) intervention to improve moderate-to-vigorous physical activity (MVPA) in adolescents with congenital heart disease.

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 limited efficacy (physical activity, fitness, and quality of life).

Results: Thirty-six participants 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. Participants accumulated 47.24 ± 16.36 minutes of MVPA/day, and had comparable outcomes to peers without heart disease (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.
