Trauma-related psychophysiological reactivity in women exposed to war-zone stress.

Women are at particular risk for Posttraumatic Stress Disorder (PTSD), but surprisingly little is known about their objective manifestations of the disorder's hallmark symptoms. Although research suggests that people with PTSD exhibit physiological reactivity to the presentation of trauma-related cues, the majority of studies to date have focused on men. We assessed the physiological reactions of three groups of trauma-exposed female Vietnam veterans (those with current PTSD, lifetime PTSD, or no PTSD) to war-related stimuli. Responses of women with current PTSD differed significantly from those without PTSD on skin conductance and systolic blood pressure, and mean levels of reactivity for women with lifetime PTSD fell between the other two groups. Although symptom severity was correlated with physiologic reactivity overall, results suggested differential relationships at the symptom cluster level. Study results replicate earlier findings with men and extend knowledge of autonomic reactivity to an important group of female survivors.

Characteristics of posttraumatic stress disorder-alcohol abuse comorbidity in women.

Trauma characteristics and symptoms were examined in 12 women diagnosed with posttraumatic stress disorder (PTSD) and alcohol abuse (AA), 13 women with PTSD only, and 22 controls. Participants served during the Vietnam era. Women completed diagnostic interviews and a questionnaire battery. Results showed that PTSD-AA women reported more childhood sexual abuse and sexual victimization during wartime service than the other two groups. Groups did not differ on other childhood trauma variables, nor on adult physical assault and traditional wartime stressor exposure. PTSD-AA women reported more PTSD, dissociation, and borderline personality traits than the other two groups. These results suggest that trauma type, specifically sexual victimization across the life span, is an important factor in dual diagnosis in women, and that women with PTSD-AA have a particularly severe level of symptoms relative to women with only PTSD and controls.

Battered women's cognitive schemata.

This study examined battered women's cognitive schema in relation to their cognitions about violence (i.e., the "meaning" attached to the violence), post-traumatic reactions to violence, and sexual victimization histories. Seventy-two battered women seeking help from an outpatient family violence clinic were subjects. The meaning of the violence (e.g., expectations of recurrent violence and of severe/lethal violence, causal attribution) was found to explain variance in cognitive schemata about SAFETY, SELF, AND OTHER (McCann and Pearlman, 1990a). All measures of cognitive schemata were significantly related to various global and specific measures of posttraumatic stress (GSI, MMPI-PTSD, IES). No differences were found for cognitive schemata based on histories of sexual victimization. Results point to the importance of assessing the impact of traumatic experiences on core cognitive beliefs as a component in the constellation of post-traumatic sequelae.
