The use of the trauma symptom inventory in the assessment of PTSD symptoms.

This study examined the Trauma Symptom Inventory (TSI; Briere, 1995) in a sample of 62 trauma-exposed community residents (80% Caucasian, 89% women), including 16 who had posttraumatic stress disorder (PTSD). PTSD and non-PTSD groups differed on seven TSI clinical scales and one validity scale, with effect sizes (r) ranging from 0.26 to 0.53. The largest effect sizes and best diagnostic utility were found for the Defensive Avoidance and Anxious Arousal scales. Diagnostic utility analyses suggest that TSI subscales in isolation are not superior to existing measures of PTSD. A logistic regression using the five most discriminating TSI scales produced a correct classification rate of 85.5%. TSI scales also demonstrated good convergent validity with other measures of PTSD. Overall, the results provide preliminary support for the use of the TSI in the assessment of PTSD.

Is dissociation a multidimensional construct? Data from the Multiscale Dissociation Inventory.

The dimensionality of dissociation was examined in a combined sample of 1,326 general population, clinical, and university participants who completed the Multiscale Dissociation Inventory (MDI). Principal components analysis identified five moderately intercorrelated factors (mean r = .39): Disengagement, Identity Dissociation, Emotional Constriction, Memory Disturbance, and Depersonalization/Derealization. Differential relationships were found between individual MDI factors and demographics, trauma history, clinical status, posttraumatic stress, and scores on other dissociation measures. Surprisingly, after controlling for sex and age, trauma exposure accounted for only 3 to 7% of the variance in MDI factors. The notion of dissociation as a general trait was not supported. Instead, dissociation may represent a variety of phenomenologically distinct and only moderately related symptom clusters whose ultimate commonality is more theoretical than empirical.

Social anxiety, depression, and PTSD in Vietnam veterans.

Many Vietnam veterans with PTSD report a high level of social anxiety and avoidance. Many traumatized individuals also suffer from symptoms of depression, which is often associated with significant problems in social functioning. In order to explore the relationship between social anxiety, depression, and PTSD, we recruited a group of Vietnam veterans with PTSD (n = 27), veterans with other mental disorders (n = 20), and veterans with no mental disorders (n = 35). Participants were administered diagnostic interviews and some of the most commonly used social anxiety instruments. Although the groups did not differ in their rates of social phobia, veterans with PTSD scored highest in most social anxiety measures. Veterans with PTSD were also more likely to be clinically depressed than veterans without PTSD at the time of the assessment. When controlling for the level of depression, the three groups no longer differed in any of the social anxiety measures. Furthermore, level of depression was the best predictor for group membership. These findings suggest that social anxiety in Vietnam combat veterans with PTSD is closely associated with mood disturbance, social withdrawal, and isolation associated with depression.

Consistency of retrospective reporting about exposure to traumatic events.

Lifetime exposure to traumatic events was assessed by means of a multimethod protocol applied to 76 male military veterans. Consistency of retrospective reporting was determined for physical and sexual assault and abuse, accidents, disasters, combat and warzone experiences, serious illness or injury, and hazardous duty. Findings demonstrate that respondents are generally consistent in reporting traumatic events, although the majority report more events upon reevaluation. Reporting about traumatic events shows some variation as a function of the life epoch in which events occurred, whether they were directly or indirectly experienced, and the type of trauma involved. Discussion addresses memory-related processes triggered by trauma evaluation or tied to characteristics of events themselves as potential sources of inconsistency.

Male war-zone veterans' perceived relationships with their children: the importance of emotional numbing.

Despite growing recognition of substantial interpersonal impairment among many war-zone veterans with posttraumatic stress disorder (PTSD), little is known about the association between PTSD symptomatology and veterans' relationships with their children. This study examined the differential pattern of associations between the symptom clusters of PTSD and the perceived father-child relationships of 66 male Vietnam veterans. Analyses revealed that only the emotional numbing cluster was significantly related to perceived quality of all relationship domains. The association between emotional numbing and perceived relationship quality remained significant in regression analyses even after controlling for fathers' family-of-origin stressors, combat exposure, depression, and substance abuse. Findings suggest that emotional numbing may be the component of PTSD most closely linked to interpersonal impairment in war-zone veterans.
