Effect of workplace bullying on posttraumatic stress disorder in nursing staff / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To investigate the relationship between workplace bullying and posttraumatic stress disorder (PTSD) in nursing staff, and to analyze the role of psychological capital between workplace bullying and PTSD.@*Methods@#From December 2014 to June 2015, convenience sampling was used to collect 496 nurses from 5 grade A tertiary hospitals in a province of China. Their workplace bullying, psychological capital, and PTSD status were assessed using the Negative Acts Questionnaire, Psychological Capital Questionnaire, and Posttraumatic Stress Disorder Self-Rating Scale, respectively. The correlation between variables was analyzed using a structural equation model.@*Results@#Among these nurses, the scores of negative acts, psychological capital, and PTSD were 37.15±12.83, 78.81±16.54, and 34.56±12.52, respectively. The score on each dimension of negative acts was positively correlated with that on each dimension of PTSD (P<0.01) ; the score on each dimension of psychological capital was negatively correlated with that on each dimension of PTSD and negative acts (P<0.01). Negative acts had a positive predictive effect on PTSD (β=0.539, P<0.01) , which was reduced after inclusion of psychological capital (β=0.513, P<0.01). The path coefficient was 0.62 for the effect of negative acts on PTSD, -0.18 for the effect of negative acts on psychological capital, and -0.11 for the effect of psychological capital on PTSD (P<0.05) .@*Conclusion@#Workplace bullying is a predictive factor for PTSD, and psychological capital plays a mediating role between workplace bullying and PTSD. The manager should reduce workplace bullying to improve the psychological capital in nursing staff and to prevent and reduce PTSD.
