It was found that the direct effect of exercise self-efficacy on depression increased progressively from low to high levels of perceived social support: from non-significant (β = 0.016, SE = 0.069, 95% CI = [−0.119, 0.151], p = 0.815), to significant (β = −0.109, SE = 0.053, 95% CI = [−0.214, −0.005], p < 0.05), to highly significant (β = −0.234, SE = 0.067, 95% CI = [−0.365, −0.104], p < 0.001).
