Abstract: BACKGROUND: The present study examines specific associations between various war events and probable posttraumatic stress disorder (PTSD) Checklist for DSM-5 [PCL-5] ? 33). METHOD: This cross-sectional study included all 806 IDF reserve soldiers (96.4 % male), mean age 30.26 (SD = 6.89) who sought help from the IDF Combat Stress Reaction Unit (CSRU) between October 7th, 2023, and August 1st, 2024 (10 months), following participation in the October 7th, 2023 War. RESULTS: A significant association emerged between probable PTSD in those who engaged in hand-to-hand combat, which was also linked with negative cognition and arousal symptom clusters. A significant correlation was found between-exposure to dead bodies or human remains and probable PTSD. Such experiences were also associated with the intrusion symptom cluster. The results indicated that being responsible for the death of an enemy combatant showed no significant relationship with probable PTSD, though it was associated only with arousal symptoms. In contrast, being responsible for the death of a noncombatant was significantly linked to probable PTSD and various PTSD symptoms, intrusion, arousal, and negative cognition symptoms. CONCLUSION: The study highlights the need to assess various combat events in relation to PTSD symptoms and probable PTSD when conducting evaluation and treatment.
