Note. IV = independent variable; MV = mediating variable; DV = dependent variable; CI = confidence intervals; Low = lower bound; Up = upper bound; PaAS = parents’ autonomy support; PeAS = peers’ autonomy support; DesN = descriptive norms; SubN = subjective norms; Att = attitude; Con = control; Int = intention. Unstandardized regression coefficients (B) and confidence intervals (CI) were obtained by applying 20,000 bootstrapping iterations. * Denotes a statistically significant regression coefficient (i.e., the 95% CI does not contain the zero value).
