Perceived stress mediates the association between perceived control and emotional distress: The moderating role of psychological resources and sex differences

Studies have confirmed that perceived control is strongly negatively correlated with emotional distress. However, few studies have explored whether perceived stress plays a potential mediating role in this relationship and whether the association between perceived stress and emotional distress is moderated by psychological resources, such as self-esteem and social support. Furthermore, it is unclear whether there are sex differences in the moderating effects of psychological resources on emotional distress. A total of 951 healthy adults (51.84% females) from different regions of mainland China participated in the study and completed questionnaires in early December 2022, when prevention and control policies concerning COVID-19 in China underwent rapid change. Perceived control negatively correlated with emotional distress, and perceived stress mediated the association between perceived control and emotional distress. In addition, both internal (i.e., self-esteem) and external psychological resources (i.e., social support) moderated the association between perceived stress and emotional distress, and the positive correlation between perceived stress and emotional distress was higher in individuals with low social support (and self-esteem) than in those with high social support (and self-esteem). We found sex differences in the moderating roles of psychological resources. Specifically, self-esteem had a moderating effect on both men and women, whereas social support had a moderating effect only on women. These findings improve understanding of the relationship between perceived control and emotional distress and suggest that intervention programs should be designed to target men and women differently.
