  2. a Regression equations predicting PA included gender, age, race, BMI percent, household income, parental PA and parental value of PA as covariates.
  3. b Two participants did not provide any responses to the Perceived Competence and Social Support questionnaires, for a total sample size of 190.
  4. cAnalyses using Actigraph® data were performed on a subsample of adolescents (n = 130) who had ≥4 complete days of data (≥8 hours of wear-time), including 2 weekend days. These analyses also included the number of complete days as a covariate.
  5. d Squared semi-partial correlations represent the proportion of the variance in MVPA(Actigraph®), MVPA(3DPAR), school sports participation, and out-of-school sports participation explained by perceived competence and social support for PA.
