Behavioral Predictors of Acute Stress Symptoms During Intense Military Training
Abstract
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.
