The effect of immediate exposure to traumatic events and gender differences is under-studied in the literature. Most studies focus on acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) phases in order to measure gender differences, and tend to neglect the immediate expo-sure to the disaster.

The main hypothesis was that female rescue personnel would exhibit higher levels of acute stress symptoms, dissociation, and depressive symptoms in the 24 hours following a traumatic event.

Twenty-three rescue personnel participated in a search and rescue operation at the Bet-Yehoshua train crash in Israel. The rescue personnel group was divided based on gender. Each participant completed a demographic questionnaire including questions that assessed psychological symptoms and issues such as perceived threat to life, the Impact of Event Scale Revised (IES-R), the Dissociative Experience Scale (DES), and the Center of Epidemiologic Studies Depression questionnaire (CES-D). Statistical inferences were calculated using t-tests and chi-square tests, along with testing of covariance (MANCOVA) in order to indentify which factors are related to psychiatric symptomatology following the immediate exposure to disaster.

The results suggest that among rescue personnel, women did not differ in their levels of acute stress, dissociation, and depressive symptoms from men.

These results suggest the possibility that the gender differences in reactions to traumatic events do not emerge in the acute stress reactions (ASR) phase (up to 24 hours after the event), but later on when people have time to process the trauma. Another possibility that may explain the discrepancy between this study and the common knowledge in the literature is that women rescue personnel are considered a highly selected group, which does not reflect on the general population of women. More studies are needed in order to substantiate these results.

The immediate impact of exposure to severe wounds, dead bodies, and immediate threat to life has been understudied. Most studies focus on the acute stress disorder and/or post-traumatic stress disorder phases in order to assess rescue personnel's symptomatology, and tend to neglect the immediate exposure to elements of the disaster.

Rescue personnel who had a history of previous exposure to dead bodies would exhibit higher levels of acute stress symptoms, dissociation, and depressive symptoms within the 24 hours following a traumatic event.

Twenty-three rescue personnel participated in the search and excavation of dead and mutilated bodies following the Bet-Yehoshua train crash in Israel.The rescue personnel group was divided based on previous exposure to dead bodies. Each participant completed a demographic questionnaire, which included a question on perceived threat to life, the impact of event scale revised, the dissociative experience scale, and the center of epidemiologic studies depression questionnaire. Student's t-tests, along with multivariate analysis of covariance (MANCOVA) were conducted in order to learn which factors are related to psychiatric symptomatology following the immediate exposure to such stressors.

Among rescue personnel, those with previous exposure to dead bodies did not differ in their levels of acute stress symptoms, dissociation, and depressive symptoms from those who were not previously exposed to dead bodies.

These results may suggest the possibility that the impact of exposure to dead bodies does not emerge in the acute stress reactions (ASR) phase (up to 24 hours after the event), but later when people have time to process the trauma. Another possibility is that the rescue coping mechanisms of detachment may serve as a buffer for the horrific sights encountered during the ASR period.
