We examined predictors of peritraumatic dissociative states PDS and quantified the link between PDS and the subsequent psychological impact of stressful events during extreme military stress. A regression model examining biological predictors of dissociative states indicated that sympathetic cardiac modulation during sleep accounted for 9.6 of the variance in PDS. In a second regression model examining behavioral predictors of PDS, perceived stress and coping styles combined to account for 47.2 of the PDS variance. PDS was positively associated with subsequently experienced avoidance p .001, hyperarousal p .01, and a total psychological impact of events score p .01. Sympathetic cardiac modulation, perceived stress, and coping styles are associated with PDS, which, in turn, influences subsequent psychological impact of stressful events.
