To test this potential indirect effect, we used a non-parametric Monte Carlo simulation
method, in which the indirect effect obtained from the a (the link between the predictor variable and the indirect effect variable) and b (the link between the indirect effect variable and the dependent variable, controlling for the remaining predictors) paths in a
series of regression
analyses is simulated k number of
times using the slopes and standard errors obtained from the data (we used k = 50,000).
