Do not reject
Note: we calculated (VAF) recommended by reference [73] to determine to reject or do not reject the mediating effect of hypotheses. As Brockman [73] stated, VAF could be less than 0.2 in the occurrence of significant indirect impact (VAF less than 0.2, no mediation; , partially mediated; VAF greater than 0.8, full mediation).
