  1. Note. aMediators for this effect included effects of the predictor on the outcome through multiple mediators. bMediators for this effect included effects of the predictor on the outcome through multiple mediators along with the direct effect of the predictor variable on the outcome. β = Standardized parameter estimate; 95% CI = 95% confidence interval of path coefficient; PAS = Perceived autonomy support; Aut. mot. (PE) = Autonomous motivation (in physical education); Aut. mot. (LT) = Autonomous motivation (in leisure time); PBC = Perceived behavioral control; Sub. norms = Subjective norms. *p < .05. **p < .01. ***p < .001
