Exposure to workplace bullying and post-traumatic stress disorder symptomology: the role of protective psychological resources.

ABSTRACT

AIM: To examine the relationship between nurses' exposure to workplace bullying and Post-Traumatic Stress Disorder symptomology and the protective role of psychological capital (PsyCap). BACKGROUND: Workplace bullying has serious organisational and health effects in nursing. Few studies have examined the relation of workplace bullying to serious mental health outcomes, such as Post-Traumatic Stress Disorder. Even fewer have examined the effect of intrapersonal strengths on the health impact of workplace bullying. METHOD: A survey of 1205 hospital nurses was conducted to test the hypothesized model. Nurses completed standardized measures of bullying, Post-Traumatic Stress Disorder and PsyCap. RESULT: A moderated regression analysis revealed that more frequent exposure to workplace bullying was significantly related to Post-Traumatic Stress Disorder symptomology regardless of the PsyCap level. That is, PsyCap did not moderate the bullying/PTSD relationship in either group. Bullying exposure and PsyCap were significant independent predictors of Post-Traumatic Stress Disorder symptoms in both groups. Efficacy, a subdimension of PsyCap, moderated the bullying/Post-Traumatic Stress Disorder relationship only among experienced nurses. CONCLUSION: Workplace bullying appears to be predictive of Post-Traumatic Stress Disorder symptomology, a serious mental health outcome. IMPLICATIONS FOR NURSING MANAGEMENT Workplace bullying is a serious threat to nurses' health and calls for programmes that eliminate bullying and encourage greater levels of positive resources among nurses.
