This study examined the effects of duty-related stress on police offic
ers. Using a sample of 100 suburban police officers, an anonymous ques
tionnaire requested demographic information and included a measure of
duty-related stressors, SCL-90-R, the Posttraumatic Stress Disorder sc
ale of the Impact of Events Scale Revised, and a locus of control scal
e. Also assessed was whether Critical Incident Stress Debriefing was e
xperienced. The results showed significant correlations between scores
on duty-related stress, somatization, and symptoms of PTSD. 13% of th
e sample met the DSM-IV (1994) diagnostic criteria for PTSD. Results o
f 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-TV AI criteria. Finally, 63% of
the respondents stated that a critical incident debriefing would be be
neficial following an extremely stressful event related to duty.
