Reciprocal longitudinal associations of supportive workplace relationships with depressive symptoms and self-rated health: A study of Korean women

Abstract

Background: Supportive relationships in the workplace are important determinants of an individual's psychological health, buffering work stress. This study aimed to estimate the bidirectional association of workplace relationships with depressive symptoms and self-rated health in female workers.

Methods: Based on the nationally representative biannual survey data from 2014 (T1) to 2020 (T4) (N = 2556), we used a random intercept cross-lagged panel model (RI-CLPM) to estimate autoregressive and cross-lagged bidirectional associations between workplace relationships and health variables.

Results: Regarding satisfactory workplace relationships and depressive symptoms, a negative correlation was observed at the between-person level. At the within-person level, the cross-lagged path showed that an increase in satisfaction with workplace relationships was related to a subsequent decrease in depressive (T1 to T2: β = -0.039; B = -0.253, P = 0.017). Further, an increase in depressive symptoms was related to subsequent relationship deterioration in the workplace (T1 to T2: β = -0.049, B = -0.007, P = 0.003). Regarding workplace relationships and self-rated health, a positive correlation was observed at the between-person level. At the within-person level, there as was no significant within-person level association between WPR and self-rated health. and the effect sizes were small.

Conclusions: This study suggests a bidirectional association between workplace relationships and depressive symptoms. Therefore, it is important to implement intervention programs that promote workplace interpersonal relationships and workers' mental health.
