Background: In societies facing prolonged exposure to war and terror, empirical research provides mixed support for the posttraumatic stress disorder (PTSD) symptom clusters groupings identified by the Diagnostic and Statistical Manual (DSM-IV-TR) as re-experiencing the event, avoidance and emotional numbing, and hyper arousal. Method: This study examines the validity of the PTSD symptom clusters in elements of Israeli society exposed to man-made trauma. Survivors (N=2,198) of seven different war and terror-related traumas were assessed using a DSM-IV-TR based PTSD inventory. Four confirmatory factor analytic models were compared. Results/Conclusions: The most acceptable model was a correlated model consisting of four factors of re-experiencing, avoidance, emotional numbing, and hyperarousal. DSM-IV-TR avoidance empirically split into active avoidance and emotional numbing. These results corroborate knowledge and suggest that in Israel, where stressors are ongoing, the PTSD symptom clusters may be reformulated in DSM-5 to consist of re-experiencing, active avoidance, emotional numbing and hyperarousal.
