Abstract

To examine the association between PSC and psychological distress, and decompose this relationship into direct, indirect and interaction pathways involving workplace MH stigma. A cross-sectional survey assessed 999 Canadian workers. Mediation was explored using a model-based potential outcomes approach, while moderation was analysed via logistic regression. The risk difference in psychological distress between high- and low-risk PSC environments was 0.122. Of this effect, 66.7% was direct, 12.9% was mediated by stigma, and 20.4% reflected PSC-stigma interaction. The stigma-distress association was stronger in high-risk PSC environments (OR = 3.58 [1.91-6.70]) than in low-risk environments (OR = 2.10 [1.04-4.23]). The majority of the association between PSC and distress is not via MH stigma, while the strength of the stigma-distress association varied by PSC level.
