Exposure to Bullying Behaviors at Work and Depressive Tendencies: The Moderating Role of Victimization From Bullying During Adolescence.

The detrimental effects of exposure to bullying behaviors at work on employees' mental health have been thoroughly documented. However, few studies have examined whether employees' prior experiences with bullying may affect the strength of this relationship. The present study tested a model where victimization from bullying in adolescence was expected to (a) predict higher exposure to bullying behaviors at work and higher levels of depressive tendencies in adulthood and (b) strengthen the relationship between exposure to bullying behaviors at work and depressive tendencies (i.e., make employees more vulnerable). The hypotheses were tested using prospective data following a cohort of 536 Norwegian respondents over a time span of 17 years, from adolescence (age of 13) to adulthood (age of 30). Victimization from bullying in junior high school was measured at the age of 13, 14, and 15, and retrospectively at the age of 18. Exposure to bullying behaviors at work was measured at the age of 30, while depressive tendencies were measured at the age of 15 and at the age of 30. As predicted, those who had been bullied more (vs. less) in adolescence tended to have higher scores on depressive tendencies as adults and reported somewhat higher exposure to bullying behaviors at work. However, contrary to our predictions, the relationship between exposure to bullying behaviors at work and depressive tendencies in adulthood was weaker among those who had been bullied more (vs. less) in adolescence. The findings contribute to the scarce literature on the role of employees' prior victimization experiences and question the notion that prior victimization from bullying produces long-term vulnerability to future experiences of bullying.

Accumulated Long-Term Exposure to Workplace Bullying Impairs Psychological Hardiness: A Five-Year Longitudinal Study among Nurses.

Personality has been hypothesized to act as antecedent as well as an outcome of workplace bullying. Still, investigations on the longitudinal relationship between bullying and personality are scarce. We investigated the relationship between accumulated exposure to bullying at work and subsequent changes in psychological hardiness. Additionally, we examined whether hardiness predicted subsequent exposure to bullying. The data were based on the Survey of Shiftwork, Sleep, and Health (SUSSH), a cohort study with annual surveys among Norwegian nurses. The participants who completed standardized instruments measuring exposure to bullying behavior at T1 (2008/09) to T4 (2012) and psychological hardiness at T1 (2008/09) and T5 (2012) were included (n = 938). The results showed that accumulated exposure to bullying (sum of exposure from T1-T4) was associated with reduced psychological hardiness at T5, adjusted for age, sex, and hardiness at baseline (ß = -0.16, t = -5.70, p < 0.001). Accumulated exposure to bullying behaviors explained 2.3% of the change in hardiness. Less hardy individuals experienced higher levels of subsequent exposure to bullying behaviors, adjusted for age, sex, and bullying at baseline (ß = -0.04, t = -2.21 p < 0.05). Long-term accumulated exposure to bullying behaviors seemed to be a stronger predictor for changes in hardiness as compared to hardiness in predicting exposure to bullying.
