Hope, Coping, and Social Support in Combat-Related Posttraumatic Stress Disorder

Dispositional hope, coping, and perceived social support were assessed among Vietnam combat veterans upon admission to and discharge from inpatient treatment for posttraumatic stress disorder (PTSD). Veterans reported lower dispositional hope than any previously described sample, and hope did not increase at discharge from treatment. At admission, higher hope was correlated with greater perceived social support coming from family (this relationship persisted when controlling for depression and PTSD symptoms). At discharge, higher hope was associated with greater perceived social support coming from family and friends and the use of adaptive coping strategies. Results indicate that hope confers a beneficial effect once veterans undergo treatment for combat-related PTSD, a finding that suggests that hope may be gone but not lost for these individuals.     

Analysis of Violent Behavior in Vietnam Combat Veteran Psychiatric Inpatients with Posttraumatic Stress Disorder

This study tested the hypothesis that male Vietnam veterans seeking inpatient treatment for PTSD (n = 228) exhibit more violent behavior compared with a mixed diagnostic group of male psychiatric Inpatients without PTSD (n = 64) and a community sample of Vietnam veterans with PTSD not undergoing inpatient treatment (n = 273). Violent acts assessed included property destruction, threats without a weapon, physical fighting, and threats with a weapon. PTSD inpatients engaged in more types of violent behavior than both comparison conditions. Correlates of violence among PTSD inpatients included PTSD symptom severity and, to a lesser degree, measures of substance abuse. These findings justify routine assessment of violent behavior among inpatients with PTSD, as well as application of specialized interventions for anger dyscontrol and aggression.     

Combat, Dissociation, and Posttraumatic Stress Disorder in Australian Vietnam Veterans

The specificity of various wartime stressors for different posttraumatic stress disorder (PTSD) symptoms is inconsistently reported in the literature. Combat, wounding, and peritraumatic dissociation have not been assessed together in their effects on each of the various PTSD symptom clusters. This cohort study of a random sample of male Australian Army Vietnam veterans yielded psychiatric assessments of 641 subjects. PTSD measures comprised symptom criteria for reexperiencing, numbing and avoidance, hyperarousal, and PTSD diagnosis both lifetime and current within the past month. Logistic regression is used to examine the effects of combat, wounding, and peritraumatic dissociation together on PTSD. Combat experiences comprised four components derived from a principal components analysis of combat experiences: direct combat exposure, exposure to death and injury, exposure to civilian death and injury, and exposure to mutilation. Each was differentially related to reexperiencing, avoidance, hyperarousal, and PTSD diagnosis. Being wounded was not related to lifetime or current PTSD and peritraumatic dissociation was related to all diagnostic components of PTSD in the presence of other variables.     

Eye Movement Desensitization and Reprocessing (EDMR) Treatment for Combat-Related Posttraumatic Stress Disorder

Despite the clinical and social impact of posttraumatic stress disorder (PTSD), there are few controlled studies investigating its treatment. In this investigation, the effectiveness of two psychotherapeutic interventions for PTSD were compared using a randomized controlled outcome group design. Thirty five combat veterans diagnosed with combat-related PTSD were treated with either (a) 12 sessions of eye movement desensitization and reprocessing, EMDR (n = 10), (b) 12 sessions of biofeedback-assisted relaxation (n = 13), or (c) routine clinical care, serving as a control (n = 12). Compared with the other conditions, significant treatment effects in the EMDR condition were obtained at posttreatment on a number of self-report, psychometric, and standardized interview measures. Relative to the other treatment group, these effects were generally maintained at 3-month follow-up. Psychophysiological measures reflected an apparent habituation effect from pretreatment to posttreatment but were not differentially affected by treatment condition.     

Twenty-Four-Hour Ambulatory Blood Pressure and Heart Rate Monitoring in Combat-Related Posttraumatic Stress Disorder

This study examined the cardiovascular correlates of posttraumatic stress disorder (PTSD) in Vietnam combat veterans using 24-hr ambulatory blood pressure and heart rate monitoring. Veterans with PTSD (n = 11) exhibited significantly higher heart rate and diastolic blood pressure across the 24 hr than veterans without PTSD (n = 7) (80.8 vs. 71.9 bpm, and 80.1 vs. 71.5 mm Hg, respectively). Heart rate during sleep was also significantly higher among veterans with PTSD, compared to veterans without PTSD (71.0 vs. 62.7 bpm). These results, based on a more naturalistic measurement methodology used outside the laboratory, support an association between PTSD and increased chronic cardiovascular arousal.     

Anger Regulation Deficits in Combat-Related Posttraumatic Stress Disorder

We describe a typology of regulatory deficits associated with anger in combat-related posttraumatic stress disorder (PTSD). Cognitive, arousal, and behavioral domain deficits in anger regulation were observed clinically in PTSD patients with high levels of anger who were participating in a multi-year trial of a structured anger treatment. We also describe a category of patients whose anger type we have termed ball of rage. These patients exhibit regulatory deficits in all three domains of anger regulation. We offer a conceptual framework to advance the understanding of anger associated with PTSD and to guide its effective treatment.     

A Concise Measure of Anger in Combat-Related Posttraumatic Stress Disorder

There is a need for a brief specific measure of anger for use in assessment of posttraumatic mental health problems. One unpublished short scale is the Dimensions of Anger Reactions (DAR; R. Novaco, 1975). This study examined the psychometric properties of the DAR using intake and 12-month data for 192 Australian Vietnam veterans with combat-related PTSD. Results showed the DAR to be unidimensional, reliable, and sensitive to change over time, and removal of two items improved the scale's properties. The DAR measures anger disposition directed towards others. Assessment of convergent validity indicated that the DAR primarily measures Trait Anger. Results suggest that the DAR is a psychometrically strong measure, potentially useful for the evaluation of anger in PTSD.     

Dissociative Processes and Symptoms of Posttraumatic Stress in Vietnam Veterans

The diagnostic taxonomy of posttraumatic stress disorder (PTSD) is a contentious issue. Commentators are divided as to whether PTSD should remain grouped with the anxiety disorders or conceptualized as a dissociative disorder. This study sought to clarify the issue by investigating the extent to which anxiety and dissociative processes differentially predict the severity of each of the three symptom clusters in PTSD. Seventy-four Australian veterans of the Vietnam War were assessed on measures of dissociation, trait anxiety, and posttraumatic stress symptomatology. Multiple regression analyses showed that all three symptoms clusters were predicted by anxiety, but the clusters differed in the pattern of their relationship with dissociation variables. The failure of pathological dissociation to predict PTSD symptoms prompts a reconsideration of the point at which dissociative mechanisms may impact on this disorder. The findings are consistent with current classification of combat-related PTSD as an anxiety disorder.     

Treatment Preferences of Vietnam Veterans with Posttraumatic Stress Disorder

This study attempted to examine patterns over time in treatment preferences of 65 veterans who completed a 4 month inpatient posttraumatic stress disorders (PTSD) program in order to reveal potentially more beneficial types of treatment. Veterans rated the severity of their symptoms and degree of benefit of 35 different treatment components at discharge, and at 4 and 12 months follow-up. Veterans rated their symptoms as having not changed at discharge, and worsening by 4 months. Veterans initially perceived components that were high in Vietnam content, exploratory in purpose, verbal in modality, and personally focused as most effective, but by 12-month follow-up they perceived these as less effective than components that were low in Vietnam content, educative, action oriented, and externally focused. These effects were strongest among veterans with higher levels of PTSD symptomatology. Combat exposure, childhood abuse, and race were generally not significant predictors of response. These results underscore the importance of further inquiry into the relative value of rehabilitative-oriented and psychotherapeutic-oriented treatments for veterans with severe and chronic PTSD.     

Trauma-Related Dissociative States and Long-Term Psychopathology in Posttraumatic Stress Disorder

Dissociative responses to trauma have been hypothesized to be associated with long-term increases in psychopathology. The purpose of this study was to examine dissociative responses to premilitary, combat-related and postmilitary traumatic events and long-term psychopathology in Vietnam combat veterans with (n = 34) and without (n = 28) posttraumatic stress disorder (PTSD). PTSD patients reported higher levels of dissociative states at the time of combat-related traumatic events than non-PTSD patients. Higher levels of dissociative states persisted in PTSD patients in the form of higher levels of dissociative states in response to postmilitary traumatic events. In addition, dissociative responses to combat trauma were associated with higher long-term general dissociative symptomatology as measured by scores on the Dissociative Experience Scale, as well as increases in the number of flashbacks since the time of the war. These findings are consistent with previous formulations that dissociation in the face of trauma is a marker of long-term psychopathology.     

A Multimodal, Second Generation, Posttraumatic Stress Disorder Rehabilitation Program

Second Generation posttraumatic stress disorder (PTSD) treatment programs were recently proposed as one component of a model of treatment of chronic PTSD. While First Generation PTSD programs emphasized trauma work, Second Generation programs emphasize skills for the present/future ability to adapt within society. The present paper describes a functioning Second Generation PTSD treatment program for Vietnam combat veterans. The guiding principles underlying this multimodal and vocational rehabilitation program are outlined.     

Posttraumatic Stress Disorder and Interpersonal Functioning in Vietnam War Veterans: A Mediational Model

This study examines the association between posttraumatic stress disorder (PTSD) and interpersonal functioning in a New Zealand community sample of 756 Vietnam War veterans. The results support previous research findings showing that PTSD adversely affects veterans' interpersonal relationships, family functioning, and marital/dyadic adjustment and show that the effects of PTSD on family functioning and dyadic adjustment are mediated by severity of interpersonal problems. It is suggested that higher levels of PTSD affect the ability of veterans to initiate and maintain interpersonal relationships and that these interpersonal problems are evident in poorer levels of family functioning and poorer dyadic adjustment.     

The Quality of the Intimate Relationships of Male Vietnam Veterans: Problems Associated with Posttraumatic Stress Disorder

This study examined the quality of the intimate relationships of male Vietnam veterans. Heterosexual couples in which the veteran had posttraumatic stress disorder (PTSD; n = 26) were compared to couples in which the veteran did not have PTSD (n = 24). Over 70% of the PTSD veterans and their partners reported clinically significant levels of relationship distress compared to only about 30% of the non-PTSD couples. Relationship difficulties appeared to encompass a wide range of areas, with PTSD veterans and their partners reporting that they had more problems in their relationships, more difficulties with intimacy, and had taken more steps toward separation and divorce than the non-PTSD veterans and their partners. The degree of relationship distress was correlated with the severity of veterans' PTSD symptoms, particularly symptoms of emotional numbing. Research and clinical implications of the results are discussed.     

Distress Experienced by Participants During an Epidemiological Survey of Posttraumatic Stress Disorder

We examined the potential for epidemiological studies of mental disorders, specifically of posttraumatic stress disorder (PTSD), to cause further harm to participants involved. Of 1,000 randomly selected Australian Vietnam veterans, 641 agreed to participate in an epidemiological survey. Participants were asked about distress experienced during the interview when traumatic events were raised. Significant distress attributed to the interview was reported by 75.3% of those with current PTSD, 56.5% of those with past PTSD, and 20.6% of those with no PTSD diagnosis. Distress did not affect participants' use of medical services following the interview nor did it affect their willingness to continue participating in the study. We concluded that research interviews about PTSD may cause short-term distress, but found no evidence of long-term harm.     

Symptom Exaggeration and Compensation Seeking Among Combat Veterans with Posttraumatic Stress Disorder

Combat veterans seeking treatment for posttraumatic stress disorder (PTSD) tend to report high levels of psychopathology on self-report instruments. The purpose of the current archival study was to replicate research on the relationships among symptom exaggeration, attempts to obtain compensation, and treatment outcome on the Beck Depression Inventory, the Mississippi Scale for Combat-Related PTSD, and selected MMPI-2 and MCMI-II subscales. Results indicated that symptom exaggeration as defined by an MMPI-2 F-K index over 13 was related to higher scores on all scales examined. Compensation seeking was not related to assessment scores or exaggeration. Neither compensation seeking nor exaggeration was related to treatment outcome. Limitations of the study and implications for future research are discussed.     

The Impact of the Homecoming Reception on the Development of Posttraumatic Stress Disorder: The West Haven Homecoming Stress Scale (WHHSS)

This study reports on the development of a self-report measure of the homecoming experience among Vietnam veterans with posttraumatic stress disorder (PTSD). The West Haven Homecoming Stress Scale (WHHSS), measuring Frequency of Events, Intensity of Feelings, and Level of Support during the first 6 months after return from overseas, and within the past 6 months, was collected from 247 veterans who were receiving inpatient treatment for PTSD. Homecoming Stress was the most significant predictor of current PTSD symptomatology superseding combat exposure, childhood and civilian traumas, and stressful life events. A factor analysis resulted in four orthogonal factors: Shame, Negative Interpersonal Interaction, Social Withdrawal, and Resentment. Homecoming Stress was unchanged over the course of a 4 month inpatient program.     

Assessing the Structure, Content, and Perceived Social Climate of Residential Posttraumatic Stress Disorder Treatment Programs

This study utilized a comprehensive assessment of program structure, content, and social climate to determine whether specialized residential posttraumatic stress disorder (PTSD) programs (SIPUs, n = 19) can be differentiated from general psychiatric units (GPUs, n = 18) within the Department of Veterans Affairs. Significant differences between program types were found: SIPUs were more clearly differentiated from the larger hospital system, had more strict patient selection criteria and program regulations, longer length of stays and lower admission rates, and spent more program time on PTSD symptoms and war zone experiences than GPUs. Veterans in the SIPUs (n = 453) rated the programs significantly higher on most social climate measures than veterans with PTSD in the GPUs (n = 153), indicating that veterans perceived these programs as more active, supportive, and better structured.     

Posttraumatic Stress Disorder and Health Status Among Female and Male Medical Patients

Posttraumatic stress disorder (PTSD) is associated with objective health problems in specific populations, such as Vietnam veterans. Less is known about PTSD and health among medical samples, especially PTSD patients with different etiologic traumas. This study examined PTSD and health in medical patients within the Department of Veterans Affairs healthcare system. A total of 134 patients completed an interview and questionnaires. Data on physician-diagnosed illnesses were gathered from medical records. PTSD diagnosis and symptoms were associated with a higher likelihood of circulatory and musculoskeletal disorders. In addition, PTSD symptoms were associated with more medical conditions. PTSD symptoms and diagnoses were also associated with poorer health related quality of life. Most of these findings remained significant after controlling for comorbid depressive, generalized anxiety disorder, and panic attack symptoms. Overall, gender did not moderate the relationship between PTSD and poorer health.     

Imagery Rehearsal in the Treatment of Posttraumatic Nightmares in Australian Veterans with Chronic Combat-Related PTSD: 12-Month Follow-Up Data

Nightmares are often a distressing symptom for veterans with chronic combat-related posttraumatic stress disorder (PTSD). A psychological treatment that has recently shown considerable promise is Imagery Rehearsal Therapy (IRT). In a pilot study by the current authors, IRT was demonstrated to be effective in the treatment of posttraumatic nightmares in a group of combat veterans up to 3-month posttreatment. This study reports the 12-month follow-up data of the pilot study, examining the longer term outcome of the IRT treatment. Twelve Australian Vietnam veterans with chronic combat-related PTSD were treated with 6 once weekly sessions of imagery rehearsal and assessed using standardised measures of nightmare frequency and intensity, PTSD, depression, anxiety and broader symptomatology at intake, posttreatment, and 3-and 12-month follow-up. Significant improvements in targeted nightmare frequency and intensity were evident to 12-month posttreatment. Similarly, improvements in overall PTSD, depression, anxiety, and broader based symptomatology were also maintained to 12 months. This study provides preliminary evidence that the positive treatment effects of IRT on posttraumatic nightmares, PTSD, and broader symptomatology in males with chronic combat-related PTSD are maintained in the longer term.
