Posttraumatic stress disorder in a national sample of female and male Vietnam veterans: Risk factors, war-zone stressors, and resilience-recovery variables.

Relationships among pretrauma risk factors (e.g., family instability, childhood antisocial behavior), war-zone stressors (e.g., combat, perceived threat), posttrauma resilience-recovery variables (e.g., hardiness, social support), and posttraumatic stress disorder (PTSD) symptom severity were examined. Data from a national sample of 432 female and 1,200 male veterans were analyzed using structural equation modeling. For both genders, direct links to PTSD from pretrauma, war-zone, and posttrauma variable categories were found; several direct associations between pretrauma and posttrauma variables were documented. Although war-zone stressors appeared preeminent for PTSD in men, posttrauma resilience-recovery variables were more salient for women. Researchers, policymakers, and clinicians are urged to take a broad view on trauma and its sequelae, especially regarding possible multiple exposures over time and the depletion and availability of important resources.

Posttraumatic stress disorder among Army Nurse Corps Vietnam veterans.

Extended an examination conducted by the 1st author (1984) of posttraumatic stress disorder (PTSD) among active-duty and reserve US Army Vietnam veterans to 361 US Army nurses (mean age 41.5 yrs) who had served in Vietnam and 351 Vietnam-era US Army nurses (mean age 38.7 yrs) who had not served in Vietnam. Analysis of questionnaire data obtained from Ss revealed a current PTSD rate for Vietnam veteran nurses of 3.3%. This rate was comparable to that found among nonnurse active-duty Army Vietnam veterans (5.1%) in the earlier study and was much lower than estimates (18–54%) for civilian Vietnam veterans. Results suggest that danger and exposure to violence may be responsible for stress reactions such as PTSD among noncombatants. Additional results indicate that social support is an important moderator in the attenuation of PTSD. (19 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Posttraumatic stress disorder and other predictors of health care consumption by Vietnam veterans

A total of 641 randomly selected Australian veterans of the Vietnam War were interviewed about their use of health care in the previous two weeks to determine what factors contributed to health care consumption. Seventy-three variables were examined by univariate linear regression and then grouped into seven categories relating to age, physical and mental health, predisposition to posttraumatic stress disorder (PTSD), deployment and repatriation experiences, and membership in veterans groups. PTSD was associated with an additional cost of $79 in health care for the two-week period. Each physical diagnosis was associated with an additional $28. Alcohol consumption was not related to health care costs. Other important variables contributing to costs were depression, educational status, the quality of the repatriation experience, and social support.     

Alternative representations of war zone stressors: Relationships to posttraumatic stress disorder in male and female Vietnam veterans.

Four conceptualizations of war zone stressor experiences were defined: traditional combat, atrocities-abusive violence, perceived threat, and malevolent environment. Items from the National Vietnam Veterans Readjustment Study (NVVRS) were reviewed for content, and stressor indexes were created. Using retrospective self-report data from the NVVRS, intercorrelations among stressor scores and between these scores and measures of posttraumatic stress disorder (PTSD) were computed for all veterans and for men and women separately. Structural equation modeling procedures followed. Results indicated that the four stressor indexes were internally consistent, reasonably distinct from one another, and influenced PTSD differentially. Men scored significantly higher than women on all 4 indexes. Whereas the pattern of relationships among the variables was comparable across genders, there was evidence that one path coefficient in the model differed for men and women.

Posttraumatic stress disorder among U.S. Army Reserve Vietnam and Vietnam-era veterans.

Analysis of questionnaire data collected in the spring of 1982 from 935 randomly selected Vietnam and Vietnam-era veterans (mean age 36.7 yrs) assigned to US Army Reserve troops units nationwide revealed a posttraumatic stress disorder (PTSD) rate for Vietnam veteran reservists of 10.9%, which is midrange between estimates for civilian (18–54%) and active duty Army (5.1%) Vietnam veterans. Results suggest that the quality of social support received during Vietnam duty and the 1st yr back may serve to either moderate or exacerbate PTSD symptomatology associated with combat experience.

Posttraumatic stress disorder, anger, and partner abuse among Vietnam combat veterans.

The authors examined interrelationships among posttraumatic stress disorder (PTSD) symptomatology, anger, and partner abuse perpetration among a sample of 60 combat veterans. Compared with PTSD-negative participants, PTSD-positive participants reported higher state anger across time and neutral and trauma prime conditions and higher anger reactivity during the trauma prime condition. PTSD-positive participants also exhibited more anger reactivity during the trauma prime than during the neutral condition. The same pattern of results was not found for anxiety reactivity during trauma memory activation. PTSD symptoms were associated with physical assault and psychological aggression perpetration, and trait anger mediated these relationships. Findings indicate a heightened anger response among PTSD-positive veterans and suggest the salience of dispositional components of anger in abuse perpetration in this population.

Posttraumatic stress disorder, exposure to combat, and lower plasma cortisol among Vietnam veterans: Findings and clinical implications.

Several clinical studies suggest that individuals with posttraumatic stress disorder (PTSD) experience neuroendocrine system alterations, resulting in significantly lower plasma cortisol. To test this hypothesis, morning serum cortisol was compared among a national sample of Vietnam "theater" veterans (n?=?2,490) and a sample of Vietnam "era" veterans (n?=?1,972) without service in Vietnam. Analysis of covariance was used to compare cortisol concentrations after adjusting for 9 covariates (education, income, race, age, smoking status, alcohol use, illicit drug use, medication use, and body mass index ). Adjusted cortisol was lower among theater veterans with current PTSD but not era or theater veterans with lifetime PTSD. Among theater veterans, cortisol was inversely related to combat exposure, with veterans exposed to heavy combat having the lowest concentrations. Analysis of plasma cortisol, together with other clinical data, may be instrumental in the future diagnosis and treatment of stress disorders.

Post-traumatic stress disorder and functioning and quality of life outcomes in female Vietnam veterans

OBJECTIVE: This investigation assessed whether current post-traumatic stress disorder (PTSD) was associated with impaired functioning in a nationally representative sample of female Vietnam veterans. METHODS: Logistic models were used to determine the association between PTSD and outcome while adjusting for demographic characteristics and medical and psychiatric co-morbidities. RESULTS: PTSD was associated with significantly elevated odds of poorer functioning in five of the six outcome domains; only the association between perpetration of violence in the past year and PTSD did not achieve statistical significance. After adjusting for demographics and medical and psychiatric co-morbidities, PTSD remained associated with significantly elevated odds of bed days, poorer physical health, and currently not working. CONCLUSIONS: Among female Vietnam veterans PTSD is associated with a broad profile of functional impairment. The significantly increased odds of impaired functioning and diminished quality of life suggest that PTSD may be the core problem of the set of problems afflicting female Vietnam veterans.     

Posttraumatic stress disorder: Silent problem among older combat veterans.

Examines posttraumatic stress disorder (PTSD) among older Vietnam combat veterans. It is suggested that PTSD among these veterans is generally chronic, silent, and exacerbated by the problems of aging. These Ss with PTSD can be divided into those with full PTSD and those with partial PTSD. Studies are cited showing prevalence rates for PTSD. The difficulties in measuring PTSD are described. Several moderating variables influence the expression of trauma problems at later life, including the presence of other stressors, health status, social support, and comorbidity. Several forms of therapy are considered, including cognitive behavioral therapy, reminiscence, and relaxational desensitization. Also, several treatment suggestions are given, advocating interventions of a stuck narrative in an aging population. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Posttraumatic stress disorder and major depression in veterans with spinal cord injury.

Objective: To explore the relationship between posttraumatic stress disorder (PTSD) and major depressive disorder (MDD) in veterans with spinal cord injury and to compare those results with results found in veterans who had sustained other traumatic injuries. Method: To investigate the relationship between PTSD and MDD in persons with spinal cord injury, the authors examined whether individuals endorsed overlapping items on measures of both disorders, evaluated the contribution of overlapping items to comorbid diagnosis, and conducted an exploratory factor analysis. Results: The overlapping symptoms between the 2 disorders did not fully explain the high rate of comorbidity, although participants who endorsed a symptom common to MDD and PTSD on 1 measure were likely to endorse the corresponding item on another measure. In both samples, items loaded on separate PTSD and MDD factors. Conclusion: MDD and PTSD appear to represent independent reactions to trauma in those individuals who had experienced either a nonspinal cord injury or a spinal cord injury. This research also provides an initial investigation of some of the possible ways that MDD and PTSD are related by addressing psychometric issues inherent in their measurement.

Posttraumatic stress disorders in Vietnam veterans: An addendum to Fairbank et al.

J. A. Fairbank et al (see record 1982-12226-001) presented a selected bibliography on posttraumatic stress disorder, Vietnam veterans, and narratives about posttraumatic stress disorder and combat experiences from other wars. A 63-item bibliographic addendum is presented that includes references from nonprofessional sources as well as traditional mental health journals.

Problems in families of male Vietnam veterans with posttraumatic stress disorder.

Interviews were conducted with a nationally representative sample of 1,200 male Vietnam veterans and the spouses or coresident partners of 376 of these veterans. The veteran interview contained questions to determine the presence of posttraumatic stress disorder (PTSD) and items tapping family and marital adjustment, parenting problems, and violence. The spouse or partner (S/P) interview assessed the S/P's view of these items, as well as her view of her own mental health, drug, and alcohol problems and behavioral problems of school-aged children living at home. Compared with families of male veterans without current PTSD, families of male veterans with current PTSD showed markedly elevated levels of severe and diffuse problems in marital and family adjustment, in parenting skills, and in violent behavior. Clinical implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Posttraumatic stress disorder and late-onset smoking in the Vietnam era twin registry.

Epidemiological and clinical studies have consistently reported associations between smoking and posttraumatic stress disorder (PTSD). This study analyzed diagnostic interview data on 6,744 members of the Vietnam Era Twin Registry to clarify the PTSD-smoking relation and to examine whether genetic liability for smoking moderated this relation. Preexisting active (unremitted) PTSD increased risk of late-onset daily smoking. Remitted PTSD decreased risk. Active PTSD increased risk of smoking at all levels of genetic liability; the effect was strongest for those with least genetic liability. This suggests PTSD represents a nongenetic pathway to late-onset smoking among individuals who were nonsmokers prior to developing PTSD. If replicated, these results identify PTSD as a risk factor for smoking that should lead to early tobacco control treatment in this population.

Caregiver burden in partners of Vietnam War veterans with posttraumatic stress disorder.

Caregiver burden in 58 partners of Vietnam War veterans with posttraumatic stress disorder (PTSD) was examined. The relationship between patient PTSD severity and caregiver burden, as well as the effect of several caregiver and patient variables on caregiver psychological status, was evaluated twice, an average of 8 months apart. Patient symptom severity was positively correlated with caregiver burden. Time 1 cross-sectional analysis indicated that greater caregiver burden was associated with greater caregiver psychological distress, dysphoria, and anxiety. Patient symptom severity also contributed to caregiver psychological distress; financial stress contributed to caregiver dysphoria and trait anxiety. Time 2 cross-sectional analyses essentially replicated the Time 1 findings. A third set of analyses examining change scores indicated that changes in caregiver burden for individuals in the sample positively predicted individual changes in caregiver psychological distress, dysphoria, and state anxiety.

Chronic posttraumatic stress disorder and chronic pain in Vietnam combat veterans

A study was conducted to investigate chronic pain patterns in Vietnam veterans with posttraumatic stress disorder (PTSD). Combat veterans with PTSD completed standardized PTSD severity, pain, somatization, and depression measures. Of 129 consecutive out-patient combat veterans with PTSD, 80% reported chronic pain. In descending order were limb pain (83%), back pain (77%), torso pain (50%), and headache pain (32%). Compared to PTSD combat veterans without chronic pain, PTSD veterans who reported chronic pain reported significantly higher somatization as measured by the Minnesota Multiphasic Inventory 2 hypochondriasis and hysteria subscales. In the sample of 103 combat veterans with PTSD and chronic pain, MMPI 2 hypochondriasis scores and B PTSD symptoms (reexperiencing symptoms) were significantly related to pain disability, overall pain index, and current pain level MMPI 2 hypochondriasis and depression scores were also significantly related to percent body pain. These results are discussed in the context of current conceptualizations of PTSD.     

Physiologic responses to loud tones in Vietnam veterans with posttraumatic stress disorder.

The authors evaluated eyeblink and autonomic components of the acoustic startle response in combat-related posttraumatic stress disorder (PTSD). Thirty-seven Vietnam combat veterans with current PTSD and 19 combat veterans without PTSD were exposed to 15 consecutive 95-dB, 500-ms, 1000-Hz tones with 0-ms rise and fall times, while orbicularis oculi electromyogram, skin conductance, and heart rate responses were measured. PTSD veterans produced larger averaged electromyographic and heart rate responses, and a slower decline in skin conductance responses, across the 15 tone presentations compared to non-PTSD veterans. Results of this study provide laboratory support for an exaggerated startle response in PTSD and replicate and extend previous findings of increased autonomic responses to loud tone stimuli in this disorder.

Ambulatory cardiovascular activity in Vietnam combat veterans with and without posttraumatic stress disorder.

The present study investigated the relationship between daily diary affect ratings and ambulatory cardiovascular activity in 117 male Vietnam combat veterans (61 with posttraumatic stress disorder [PTSD] and 56 without PTSD). Participants completed 12–14 hr of ambulatory monitoring and daily diary affect ratings. Compared with veterans without PTSD, veterans with PTSD reported higher negative affect and lower positive affect in daily diary ratings. No differences were detected for mean laboratory initial recordings or mean ambulatory heart rate (HR), systolic blood pressure (SBP), or diastolic blood pressure (DBP). However, compared with veterans without PTSD, veterans with PTSD demonstrated higher SBP and DBP variability and a higher proportion of HR activity (compared with initial recording values) during daily activity. There was a significant Time of Day × Group interaction for mean HR, with a trend for PTSD participants to maintain HR levels during evening hours.

Interpersonal problems of Vietnam combat veterans with symptoms of posttraumatic stress disorder.

274 male veterans seeking treatment for substance abuse were divided on the basis of combat experience and DSM-III criteria of posttraumatic stress disorder (PTSD). Ss with evidence of PTSD were compared with a non-PTSD group of Vietnam combat veterans and a noncombat group of Vietnam-era veterans on measures of specific interpersonal problems using the Horowitz Interpersonal Problem Inventory, traditional measures of family and social adjustment, and the MMPI. The PTSD group scored significantly higher on clusters of problems dealing with intimacy and sociability than did either of the comparison groups. PTSD Ss also scored higher on the MMPI scales of Paranoia, Psychopathic Deviate, Social Introversion, Social Maladjustment, Family Problems, and Manifest Hostility, but did not differ from other groups on Family Environment Scale variables. Results, which were not attributable to premilitary adjustment differences or to confounding demographic variables, are compared to previous studies, and research questions that remain outstanding are discussed.

A general model for the treatment of post-traumatic stress disorder in war veterans.

Presents a general conceptual model of the recovery processes required for a successful therapeutic resolution of war-related PTSD. These processes involve relationship building, the development of emotional and cognitive connections with the trauma, recognition of the divergence between pre- and post-trauma values, modifying one's sense of self, establishing meaning for the trauma, and reestablishing appropriate self management and social skills. The authors emphasize the importance of the therapist–veteran relationship to client engagement in the recovery process. Case vignettes are included to illustrate model dynamics.

Interpersonal problem solving and coping reactions of Vietnam veterans with posttraumatic stress disorder.

In order to assess the relation between posttraumatic stress disorder (PTSD) and interpersonal problem solving and coping, 43 Vietnam veterans were assigned to the following four groups: (a) combat veterans with PTSD, (b) combat veterans with severe adjustment problems but not PTSD-diagnosable (AP), (c) combat veterans who were well adjusted (WA), and (d) veterans with little or no combat exposure who served during the Vietnam era (ERA). Multivariate analyses of variance indicated that both the PTSD and AP groups reported less effective coping reactions and poorer problem solving than both the WA and ERA groups. The PTSD subjects also reported less effective problem solving and less problem-focused coping reactions than the AP veterans. Implications of these results are discussed.
