This study investigated prevalence rates of secondary traumatic stress symptoms in Israeli Police forensic technicians, and the relationship between these symptoms and perceived social support as well as perceived severity of prior trauma (combat, work, personal). Ninety technicians from the Israeli Police Forensic Investigation Unit participated in the study. Intrusion and avoidance measured within the medium range of severity, whereas distress symptoms were below clinical threshold. Intrusion was significantly related to avoidance, distress, and the perceived severity of prior personal and work-related exposure. No significant relationship was found between perceived social support and secondary traumatic stress symptoms. The data suggest that this cohort utilized avoidance effectively as a defense against intrusion.
