Young people’s perspectives on integrating physical activity interventions into youth substance use treatment practice: a mixed-methods study

PA levels and psychological distress predict perceived barriers to PA in young people with problematic SU. PA barriers predict treatment acceptability of PA interventions. Knowledge of such predictors may inform treatment decisions by clinicians. Young people's insights should be integrated into PA intervention research to inform intervention and understand the unique barriers, preferences and needs of youth affected by problematic SU. Integration of young people's perspectives may increase behaviour change, as well as motivation, engagement and positive feelings in young people participating in PA interventions within substance use treatment.
