The findings indicated that repeated exposure to traumatic incidents was common among all the respondents. Officers reported experiencing recurring memories of the incidents, easily losing their temper, recurring images or thoughts, sleeping difficulties, jumpiness or restlessness, and difficulty concentrating.

The findings suggest that the symptoms of police officer stress may be delayed and may resemble the symptoms of Posttraumatic Stress Disorder (PTSD).

Participants were mainly Caucasian males and were patrol officers. Data were analyzed using descriptive statistical techniques. Tables, references
