Figure 2.

Direct effects and explained variance in the mediation model. Unstandardized regression coefficients shown were obtained by applying 20,000 bootstrapping iterations. The values in the top (bottom) row show the estimates for girls (boys). For the sake of clarity, the following values have not been included in the graphical representation: (a) the effects of the control variable (i.e., past exercise behaviour in the last six months), and (b) the covariance terms between parents’ and peers’ autonomy support. * Denotes a statistically significant regression coefficient (i.e., the 95% CI does not contain the zero value).
