Note. c = total effect, c’ = direct effect, a = predictor-mediator relationship, b = mediator-outcome relationship, a*b = indirect effect. ***p < .001, **p < .01, *p < .05. Exact p values are reported for all standardised indirect effects. Bolded variables are significant mediations after adjusting for Type I error
