Notes. The presented results are non-standardised estimation coefficients following the PROCESS procedure as described in Hayes [23]. Standard errors are between parentheses. As proposed by Hayes [23], standard errors for ab are based on 10.000 bias-corrected bootstrap samples; standard errors for a, c, b and c’ are based on the normal theory approach.
