Study shows mediating role of physical self-concept in links between MVPA and psychological ill-being in adolescents, indicating age and socioeconomic factors matter.
Key Points
Physical self-concept partially mediates the effect of moderate-to-vigorous physical activity on depression in adolescents with ADHD, explaining 23% of the variance.
The association between MVPA and stress is also partially mediated by physical self-concept, which accounts for 20% of the variance, especially due to appearance perception.
Age, maternal education, and socioeconomic status significantly moderate the relationships between physical self-concept, depression, and stress outcomes.
Promoting moderate-to-vigorous physical activity may be particularly beneficial for older adolescents and those from lower socioeconomic backgrounds with ADHD.
