Positive Emotions as a Potential Mediator of a Multi-Component Positive Psychology Intervention Aimed at Increasing Mental Well-Being and Resilience

We examined mediators of a multi-component positive psychology intervention for healthy employees. We analyzed data from a randomized controlled trial involving 158 participants who were assigned to a six-session intervention program or a wait-list control group. In total, 144 participants completed baseline and post-test assessment. The mediating effects of positive emotions and psychological flexibility on treatment outcomes mental well-being and resilience at post-test assessment were examined. We also examined the influence of a range of moderators on the relationship between the intervention and the outcomes. Mediator analyses showed that these improvements possibly and partially work through increasing positive emotions. Psychological flexibility could not be considered a mediator. However, due to inability to infer causality, definite conclusions on the mediating effect of positive emotions cannot be drawn. In relation to mental well-being, a significant moderating effect for ethnicity was found in the intervention group.
