Duty-related stressors and PTSD symptoms in suburban police officers.

This study examined the effects of duty-related stress on police officers. Using a sample of 100 suburban police officers, an anonymous questionnaire requested demographic information and included a measure of duty-related stressors, SCL-90-R, the Posttraumatic Stress Disorder scale of the Impact of Events Scale-Revised, and a locus of control scale. Also assessed was whether Critical Incident Stress Debriefing was experienced. The results showed significant correlations between scores on duty-related stress, somatization, and symptoms of PTSD. 13% of the sample met the DSM-IV (1994) diagnostic criteria for PTSD. Results of the regression analysis showed the best predictors for the diagnosis of PTSD were associated with the factor of Exposure to Death and Life Threat, which corresponds to the DSM-IV AI criteria. Finally, 63% of the respondents stated that a critical incident debriefing would be beneficial following an extremely stressful event related to duty.
