Parallel mediation of mothers (Model A) and fathers (Model B) of children with rare congenital surgical diseases. Note. The Path a represents the effect of stressor pile-up on each mediator; Path b represents the combined effects of each mediator on parental mental health; the direct effect represents the effect of the stressor pile-up on parental mental health while keeping levels of the mediators constant; the indirect effect represents the combined effect of path a and path b and therefore the mediation. The total effect represents the combined indirect and direct effects. Significance inferences at the α = .05 for effects are based upon the notion of whether confidence intervals include zero.
