Dissociation, hardiness, and performance in military cadets participating in survival training.
The present study examined the relationship between peritraumatic dissociation, hardiness, and military performance in Norwegian Navy officer cadets (N = 80) after a simulated prisoner of war (POW) exercise. The cadets reported symptoms of peritraumatic amnesia, depersonalization, and derealization in response to a mild stress experience (time point 1) and exhibited a significant increase in such symptoms when subsequently exposed to a highly stressful experience of being placed in a mock POW camp (time point 2). Symptoms of peritraumatic dissociation were significantly and negatively related to performance, and predicted between 16 and 26% of the variance between subjects. A subscale of the personality hardiness measure (i.e., the subdimension of challenge) was negatively associated with peritraumatic dissociation in response to both the mild stress situation and the more stressful POW exercise in study subjects. Hardiness was not significantly associated with military performance scores. The present data indicate that individual differences in attribution style and in a propensity to dissociate significantly affect military performance during exposure to high stress situations.
