Secondary traumatic stress and associated factors among Japanese nurses working in hospitals.

Nurses can experience secondary traumatic events while caring for patients. However, the severity of this issue is underestimated in Japan. To evaluate the prevalence and factors associated with secondary traumatic stress among general hospital nurses, we carried out a cross-sectional study at a general hospital in August 2006. The rate of experiencing secondary trauma was 90.3% (159 of 176 nurses; 52.1% response rate). The median score of the Impact of Event Scale-Revised was 4.0 (range, 0-56). In multiple regression analyses, variables correlated with the Impact of Event Scale included neuroticism, trauma severity and feelings of self-reproach. It is necessary to develop support systems for nurses at risk for secondary traumatic stress.
