Unique Patterns of Substance Misuse associated with PTSD, Depression, and Social Phobia.

OBJECTIVES: This study investigated the relations between post-trauma psychopathology and substance abuse in a sample of trauma-exposed college students (n = 136) assigned to four groups based on primary diagnosis: posttraumatic stress disorder, depression, social phobia, or well-adjusted (participants who had low levels of distress). Groups were compared on a series of dimensions of substance use/abuse. RESULTS: Participants in the PTSD group evidenced greater substance use and abuse than those in the social phobia and well-adjusted groups on several dimensions and greater alcohol consumption than the depressed group.

Prospective study of externalizing and internalizing subtypes of posttraumatic stress disorder and their relationship to mortality among Vietnam veterans.

Posttraumatic stress disorder (PTSD) can be a complex disorder, and some studies have found that samples of individuals with PTSD contain subtypes that may relate to health outcomes. The goals were to replicate previously identified PTSD subtypes and examine how subtype membership relates to mortality. Data from the Vietnam Experience Study and a clinical sample of Vietnam veterans were combined (n = 5248) to address these research questions.

A comparison of PTSD symptom patterns in three types of civilian trauma.

Posttraumatic stress disorder (PTSD) is assumed to be an equivalent syndrome regardless of the type of traumatic event that precipitated it. However, the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) and previous research suggest that the clinical presentation of PTSD varies by trauma type.

Evaluation of lifetime trauma exposure and physical health in women with posttraumatic stress disorder or major depressive disorder.

The current study examines lifetime trauma exposure rates in 148 women with posttraumatic stress disorder (PTSD), major depressive disorder (MDD), or neither diagnosis and whether this is related to measures of PTSD, depression, hostility, health symptoms, and health care utilization. Findings indicate that multiple trauma exposures were prevalent in this sample, with 96% of those with PTSD and 79% of those with MDD reporting three or more trauma exposures compared to 46% in the comparison group. Controlling for diagnostic status, regression analysis for PTSD symptom severity reveals that the trauma exposure adult physical assault category was significantly associated with more severe PTSD and depressive symptoms, whereas the childhood violence category was most associated with increased hostility.

Substance use behaviors as a mediator between posttraumatic stress disorder and physical health in trauma-exposed college students.

Introduction: Research within the field of traumatic stress has documented a strong link between posttraumatic stress disorder (PTSD) and adverse physical health outcomes, although the mechanisms contributing to this relationship are unclear.

Method: The current study examined substance use behaviors as one such mediator in a mixed civilian trauma population. Participants were 136 undergraduates exposed to a variety of civilian traumas.

Ambulatory cardiovascular activity and hostility ratings in women with chronic posttraumatic stress disorder.

Background: The objective of the current study is to evaluate the relationship between hostility and ambulatory cardiovascular activity in women with and without posttraumatic stress disorder (PTSD).

Methods: One hundred and one women completed 24 hours of ambulatory monitoring and standardized diagnostic and hostility measures. Generalized estimating equations analysis was used to examine the effects of group and hostility factor scores (hostile beliefs, overt hostility, and covert hostility) on ambulatory heart rate (AHR) and ambulatory systolic (ASBP) and diastolic (ADBP) blood pressure.

Self-mutilative behaviors in male veterans with posttraumatic stress disorder.

Self-mutilative behaviors (SMB) were examined in a sample of male veterans with posttraumatic stress disorder (PTSD). The primary objective was to determine the prevalence of SMB and any physical, cognitive, or affective antecedents and correlates for these behaviors. Participants included 509 male veterans with PTSD and levels of PTSD, depression, alcohol use, hostility, and impulsivity were evaluated to determine if these variables were related to SMB.

The utility of the PAI and the MMPI-2 for discriminating PTSD, depression, and social phobia in trauma-exposed college students.

This study investigated the Minnesota Multiphasic Personality Inventory-Revised (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) and the Personality Assessment Inventory (PAI; Morey, 1991) with regard to each instrument's utility for discriminating post-traumatic stress disorder (PTSD) from depression and social phobia in a sample of college students with mixed civilian trauma exposure. Participants were 90 trauma-exposed undergraduates (16 male, 74 female) classified into one of four groups: PTSD, depressive disorders, social phobia, and well-adjusted. For both the PAI and the MMPI-2, profile analysis revealed that the groups differed in the elevation and shape of their profiles.

A comparison of personalized feedback for college student drinkers delivered with and without a motivational interview.

Objective: This study evaluated the relative efficacy of personalized drinking feedback (PDF) delivered with and without a motivational interview (MI) for college student drinkers.

Method: Heavy-drinking college students (N = 54; 691% female) were identified from a large screening sample and randomly assigned either to receive PDF during a single MI session or to receive PDF without an MI. Of these participants, 51 (94%) completed a 6-month follow-up assessment that included measures of alcohol consumption and alcohol-related problems.
