Posttraumatic stress disorder symptoms, physiological reactivity, alcohol problems, and aggression among military veterans.

This study examined the association between posttraumatic stress disorder (PTSD) symptomatology and aggressive behavior among a sample of male Vietnam veterans (N = 1,328). Results indicated that the hyperarousal PTSD symptom cluster evidenced the strongest positive association with aggression at the bivariate level when compared with the other PTSD symptom clusters. When the PTSD symptom clusters were examined together as predictors, hyperarousal symptoms evidenced a significant positive relationship with aggression, and avoidance/numbing symptoms were negatively associated with aggression. Examination of potential mediators indicated that hyperarousal symptoms were directly associated with aggression and indirectly related to aggression via alcohol problems. Reexperiencing symptoms were associated with aggression only indirectly and through their positive association with physiological reactivity and negative association with alcohol problems. Study results highlight the complexity of the relationship between PTSD symptoms and aggression, and suggest possible mechanisms explaining this association.

Posttraumatic Stress Disorder and Current Relationship Functioning Among World War II Ex-Prisoners of War.

This study examined the association of posttraumatic stress disorder (PTSD) with the quality of intimate relationships among present-day male World War II ex-prisoners of war (POWs). Ex-POWs had considerable marital stability; those with PTSD were no less likely to be in an intimate relationship. Ex-POWs in an intimate relationship who had PTSD (N=125 ) were compared with ex-POWs in a relationship who did not have PTSD (N=206). Marital functioning was within a range expected for persons without traumatic exposure. Yet, over 30% of those with PTSD reported relationship problems compared with only 11% of those without PTSD. Ex-POWs with PTSD reported poorer adjustment and communication with their partners and more difficulties with intimacy. Emotional numbing was significantly associated with relationship difficulties independent of other symptom complexes and severity of PTSD. Implications for clinical practice are discussed.

Longitudinal analyses of family functioning in veterans and their partners across treatment.

Objective: This study evaluated the relations between posttraumatic stress disorder (PTSD) symptoms and poor family functioning in veterans and their partners. Method: Data were collected from Caucasian veterans with PTSD (N = 1,822) and their partners (N = 702); mean age = 53.9 years, SD = 7.36. Veterans completed the Posttraumatic Checklist Military Version (PCL-M) and, along with their partners, completed the McMaster Family Assessment Device (FAD-12). Assessments were conducted at intake into a treatment program at 3 months and 9 months posttreatment. Results: Structural equation models (SEMs) were developed for veterans as well as for veterans and their partners. Poor family functioning for veterans at intake predicted intrusion (β = .08), hyperarousal (β = .07), and avoidance (β = .09) at 3 months posttreatment. At 3 months posttreatment, family functioning predicted hyperarousal (β = .09) and avoidance (β = .10) at 9 months. For veterans and their partners, family functioning at intake predicted avoidance (β = .07) at 3 months, and poor family functioning at 3 months predicted intrusion (β = .09) and hyperarousal (β = .14) at 9 months. The reverse pathways, with PTSD symptoms predicting poor family functioning, were only evident with avoidance (β = .06). Conclusion: Family functioning may play a role in treatment for veterans.

Marital relations among former prisoners of war: Contribution of posttraumatic stress disorder, aggression, and sexual satisfaction.

In this study, the authors examined the marital adjustment, spousal aggression, and sexual satisfaction of prisoners of war (POWs) 3 decades after their release. More specifically, the authors examined the extent to which impaired marital relations among former POWs are an outcome of their captivity or of the posttraumatic stress disorder (PTSD) that some of them developed. The authors compared 25 former POWs with PTSD, 85 former POWs without PTSD, and 104 control veterans. The findings reveal that the marital problems of former POWs are more related to PTSD than to their captivity. PTSD is related to decreased marital satisfaction, increased verbal aggression, and heightened sexual dissatisfaction among former POWs.

Confirmatory factor analyses of posttraumatic stress symptoms in deployed and nondeployed veterans of the Gulf War.

Confirmatory factor analysis was used to compare 6 models of posttraumatic stress disorder (PTSD) symptoms, ranging from 1 to 4 factors, in a sample of 3,695 deployed Gulf War veterans (N = 1,896) and nondeployed controls (N = 1,799). The 4 correlated factors-intrusions, avoidance, hyperarousal, and dysphoria-provided the best fit. The dysphoria factor combined traditional markers of numbing and hyperarousal. Model superiority was cross-validated in multiple subsamples, including a subset of deployed participants who were exposed to traumatic combat stressors. Moreover, convergent and discriminant validity correlations suggested that intrusions may be relatively specific to PTSD, whereas dysphoria may represent a nonspecific component of many disorders. Results are discussed in the context of hierarchical models of anxiety and depression. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Comparing posttraumatic stress disorder's symptom structure between deployed and nondeployed veterans.

We tested two empirically validated 4-factor models of posttraumatic stress disorder (PTSD) symptoms using the PTSD Checklist: King, Leskin, King, and Weathers' (1998) model including reexperiencing, avoidance, emotional numbing, and hyperarousal factors, and Simms, Watson, and Doebbeling's (2002) model including reexperiencing, avoidance, dysphoria, and hyperarousal. Our aim was to determine which fit better in two groups of military veterans: peacekeepers previously deployed to a war zone (deployed group) and those trained for peacekeeping operations who were not deployed (nondeployed group). We compared the groups using multigroup confirmatory factor analysis. Adequate model fit was demonstrated among the nondeployed group, with no significant difference between King et al.'s (1998) model (separating avoidance and numbing) and Simms et al.'s (2002) similar model involving a dysphoria factor. A better fitting factor structure consistent with Simms et al.'s (2002) model was found in the deployed group. Comprehensive measurement invariance testing demonstrated significant differences between the deployed and nondeployed groups on all structural parameters, except observed variable intercepts (thus indicating similarities only in PTSD item severity). These findings add to researchers' understanding of PTSD's factor structure, given the revision of PTSD that will appear in the forthcoming 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 2010)—namely, that the factor structure may be quite different between groups with and without exposure to major traumatic events.

Vietnam combat veterans with Posttraumatic Stress Disorder: Analysis of marital and cohabitating adjustment.

21 help-seeking Vietnam combat veterans (mean age 34.71 yrs) with a diagnosis of posttraumatic stress disorder (PTSD) were compared with 18 help-seeking combat veterans (mean age 33.44 yrs) without evidence of PTSD and 21 help-seeking veterans (mean age 33.4 yrs) with minimal combat experience on indexes of cohabitating and marital adjustment. Also, premilitary adjustment was assessed and validated by relative's reports. The PTSD group reported significantly more problems than did the other groups with self-disclosure and expressiveness to their partners, physical aggression toward their partners, and global relationship adjustment. The PTSD group did not differ from the other groups on measures of intimacy and affectionate behavior. The findings were not attributable to premilitary adjustment, response style, or demographic factors. Previous reports that combat veterans have special difficulties expressing positive emotions were not supported by present findings.

Together in pain: Attachment-related dyadic processes and posttraumatic stress disorder.

We used actor–partner interdependence modeling to explore associations among attachment-related dyadic processes, posttraumatic stress disorder (PTSD) in war veterans, and secondary traumatic stress (STS) in their wives. A sample of 157 Israeli couples (85 former prisoners of war and their wives and a comparison group of 72 veterans not held captive and their wives) completed self-report scales assessing attachment insecurities (anxiety, avoidance) and PTSD symptoms. For both groups of veterans and their wives, attachment anxiety was associated with the severity of their own and their spouses' PTSD and STS. Avoidant attachment was associated with PTSD and STS only in couples that included a former prisoner of war. A complex pattern of associations involving avoidant attachment was observed in the actor–partner analyses of these couples. The study demonstrates that attachment-related dyadic processes play a role in the development and maintenance of PTSD in traumatized veterans and STS in their wives.

Childhood physical abuse, internalized homophobia, and experiential avoidance among lesbians and gay men.

This study explored relations among childhood physical abuse, internalized homophobia, experiential avoidance, and current psychological symptoms in a community sample of 122 adult lesbians and 115 adult gay men. Childhood physical abuse predicted depression and posttraumatic stress disorder (PTSD) symptoms. Furthermore, for gay men, internalized homophobia completely mediated the relation between childhood physical abuse and depression symptoms and partially mediated the relation between childhood physical abuse and PTSD symptoms. However, experiential avoidance did not mediate these relations. In contrast, experiential avoidance partially mediated the relation between childhood physical abuse and PTSD symptoms among lesbians; however, internalized homophobia did not mediate these relations. These findings suggest that internalized homophobia and experiential avoidance may have differential mediating roles in predicting psychological symptoms among lesbians and gay men who have experienced childhood physical abuse.

The implication of combat-induced stress reaction, PTSD, and attachment in parenting among war veterans.

This study examined parental functioning, parental satisfaction, and concern for offspring during their child's military service, among war veterans, some of whom suffered from acute combat-induced stress reaction (CSR) and posttraumatic stress disorder (PTSD). In addition, we examined the additive and interactive contributions of CSR, PTSD and attachment dimensions to parenting measures. The sample consisted of 477 participants divided into two groups: a clinical group of veterans who had been diagnosed with CSR on the battlefield (N = 267), and a matched control group of veterans who did not suffer from CSR (NCSR; N = 210). CSR, PTSD, avoidant-attachment, and anxious-attachment, were all related to lower levels of parental functioning and satisfaction. Veterans who suffered from both CSR and PTSD reported more concern for their offspring during their child's military service compared to veterans with PTSD but without antecedent CSR. Attachment dimensions and specifically attachment-avoidance, made the greatest contribution to parenting measures, followed by posttraumatic symptoms. In addition, attachment-avoidance moderated the relationship between posttraumatic symptoms and parental functioning. Theoretical and clinical implications of these results are discussed.

Posttraumatic stress disorder and depression symptomatology in a sample of Gulf War veterans: A prospective analysis.

The authors examined the relationship over time of posttraumatic stress disorder (PTSD) and depression symptoms in a sample of Gulf War veterans. A large sample (N?=?2,949) of Gulf War veterans was assessed immediately following their return from the Gulf region and 18–24 months later. Participants completed a number of self-report questionnaires including the Mississippi Scale for Combat–Related PTSD (T. M. Keane, J. M. Caddell, & K. L. Taylor, 1988) and the Brief Symptom Inventory (L. R. Derogatis & N. Melisaratos, 1983) at both time points and an extended and updated version of the Laufer Combat Scale (M. Gallops, R. S. Laufer, & T. Yager, 1981) at the initial assessment. A latent-variable, cross-lag panel model found evidence for a reciprocal relation between PTSD and Depression. Followup models examining reexperiencing, avoidance-numbing, and hyperarousal symptoms separately showed that for reexperiencing and avoidance-numbing symptoms, the overall reciprocal relation held. For hyperarousal symptoms, however, the association was from early hyperarousal to later depression symptoms only. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Posttraumatic intrusion, avoidance, and social functioning: A 20-year longitudinal study.

The study assesses posttraumatic intrusion, avoidance, and social functioning among 214 Israeli combat veterans from the first Lebanon War with and without combat stress reaction (CSR) 1, 2, 3, and 20 years after the war. CSR veterans reported higher intrusion and avoidance than did non-CSR veterans. With time, there was a decline in these symptoms. In addition, intrusion and avoidance were associated with problems in social functioning on a given year, and they longitudinally predicted social dysfunction 2, 3, and 20 years after the war. CSR veterans presented stronger temporal covariations between intrusion-avoidance and social functioning. The findings suggest that CSR is a marker for future psychopathology and point to the role of avoidance in social dysfunction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

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)     

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.

Cholinergic/serotonergic interactions in hypothermia: implications for rat models of depression

Vietnam combat veterans (N = 151) with chronic posttraumatic stress disorder (PTSD) completed measures of atrocities exposure, combat exposure, PTSD symptom severity, guilt and interpersonal violence. PTSD symptom severity, guilt and interpersonal violence rates were similar to previously reported studies that examined treatment seeking combat veterans with PTSD. Controlling for combat exposure, endorsement of atrocities exposure was related to PTSD symptom severity, PTSD B (reexperiencing) symptoms, Global Guilt, Guilt Cognitions, and cognitive subscales of Hindsight-Bias/Responsibility and Wrongdoing. These results are discussed in the context of previous research conducted regarding atrocities exposure and PTSD.     

Prewar factors in combat-related posttraumatic stress disorder: Structural equation modeling with a national sample of female and male Vietnam veterans.

Structural equation modeling was used to examine relationships among prewar factors, dimensions of war-zone stress, and current posttraumatic stress disorder (PTSD) symptomatology using data from 1,632 female and male participants in the National Vietnam Veterans Readjustment Study (R. A. Kulka et al; 1990). For men, previous trauma history (accidents, assaults, and natural disasters) directly predicted PTSD and also interacted with war-zone stressor level to exacerbate PTSD symptoms for high combat-exposed veterans. Male veterans who entered the war at a younger age displayed more symptoms. Family instability, childhood antisocial behavior and age had indirect effects on PTSD for men. For women, indirect prewar effects emanated from family instability. More attention should be given to critical developmental conditions, especially family instability and earlier trauma exposure, in conceptualizing PTSD in adults.

Comparative efficacy, speed, and adverse effects of three PTSD treatments: Exposure therapy, EMDR, and relaxation training.

The authors examined the efficacy, speed, and incidence of symptom worsening for 3 treatments of posttraumatic stress disorder (PTSD): prolonged exposure, relaxation training, or eye movement desensitization and reprocessing (EMDR; N=60). Treatments did not differ in attrition, in the incidence of symptom worsening, or in their effects on numbing and hyperarousal symptoms. Compared with EMDR and relaxation training, exposure therapy (a) produced significantly larger reductions in avoidance and reexperiencing symptoms, (b) tended to be faster at reducing avoidance, and (c) tended to yield a greater proportion of participants who no longer met criteria for PTSD after treatment. EMDR and relaxation did not differ from one another in speed or efficacy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Family functioning predicts outcomes for veterans in treatment for chronic posttraumatic stress disorder.

A longitudinal framework was used to examine the competing hypotheses of (a) whether family functioning predicts changes in posttraumatic stress disorder (PTSD) symptoms or (b) whether PTSD symptoms predict changes in family functioning. Veterans (N = 311) admitted to a treatment program completed a series of questionnaires at 3 time points: at intake, from intake to completion of a treatment program, and at the 6-month follow-up. Alcohol use and general mental health symptoms were also measured at intake. A cross-lagged panel model using structural equation modeling analyses indicated that family functioning was a moderate predictor of PTSD symptoms at posttreatment and at the 6-month follow-up. PTSD was not a significant predictor of family functioning across time and alcohol use, and general mental health symptoms did not affect the overall findings. Further analyses of PTSD symptom clusters indicated that the avoidance symptom cluster was most strongly related to family functioning. Targeting family relationships for treatment may be important in the future for veterans with PTSD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Psychological symptoms and marital satisfaction in spouses of Operation Iraqi Freedom veterans: Relationships with spouses' perceptions of veterans' experiences and symptoms.

Much research has shown that spouses of combat veterans with posttraumatic stress disorder (PTSD) have higher rates of psychological and marital distress than do spouses of veterans without PTSD; however, very few studies have examined potential mechanisms of this increased vulnerability. The current study examined spouses of National Guard soldiers recently returned from deployments in Iraq. In addition to documenting elevated levels of psychological symptoms in these spouses, the authors found that spouses experienced greater symptom severity when they perceived high levels of symptoms in soldiers but the soldiers endorsed low levels of symptoms. Furthermore, spouses' marital satisfaction was negatively linked to soldiers' self-reported symptom severity only when spouses perceived that soldiers had experienced low levels of combat activity while deployed. When spouses perceived high levels of such activity, soldiers' self-reported symptoms had no relationship with spouses' marital satisfaction. These findings highlight the importance of interpersonal perceptions in intimate relationships and are consistent with the notion that uncontrollable attributions for a relative's mental health problems may provide a buffer against relationship distress.

A test of behavioral family therapy to augment exposure for combat-related posttraumatic stress disorder.

This study tested a family-based skills-building intervention in veterans with chronic combat-related posttraumatic stress disorder (PTSD). Veterans and a family member were randomly assigned to 1 of 3 conditions: (a) waiting list, (b) 18 sessions of twice-weekly exposure therapy, or (c) 18 sessions of twice-weekly exposure therapy followed by 16 sessions of behavioral family therapy (BFT). Participation in exposure therapy reduced PTSD positive symptoms (e.g., reexperiencing and hyperarousal) but not PTSD negative symptoms. Positive symptom gains were maintained at 6-month follow-up. However, participation in BFT had no additional impact on PTSD symptoms. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
