Background. Peritraumatic dissociation and distress are strong predictors of Acute Stress
Disorder (ASD) and Posttraumatic Stress Disorder (PTSD) development. However, there is
limited data concerning gender differences in these relations, particularly among victims of
violent crimes (VVC). Objective. Examine whether peritraumatic dissociation and distress
predict the number of ASD symptoms differently for men and women VVC. Methods. 162
adults (97 women, Mage = 39.6 yrs.), 63% of whom experienced physical assaults, completed the
Acute Stress Disorder Interview, the Peritraumatic Dissociative Experience Questionnaire, and
the Peritraumatic Distress Inventory. Analyses included t-tests and multiple hierarchical
regressions models controlling for known PTSD risk factors. Results. The regression model
showed dissociation and distress to be significant predictors of ASD for both men and women (β
= .349 and β =.312 respectively; all p<.001). A significant 3-way interaction was also observed
between peritraumatic distress (PDI), past potentially traumatic experiences and gender. In
simple slopes analyses, the combination of high levels of PDI and of a high number of past
potentially traumatic events were associated with greater risk of ASD in men only (b=3.78,
p<.001). However, women experienced greater PDI (t (157) = 5.844, p = .005) than men, and
elevated distress was associated with more ASD symptoms independently of past traumatic
events. Major implications. Gender differences were revealed as a function of past potentially
traumatic experiences. There is a cumulative impact of past potential traumas and current distress
that predicts ASD in men, while in women; it contributes to ASD via increased distress.
