The contribution of loneliness and posttraumatic stress disorder to marital adjustment following war captivity: a longitudinal study

This prospective study examined the relative contribution of loneliness and posttraumatic stress disorder (PTSD) to marital adjustment among Israeli veterans of the 1973 Yom Kippur war. Specifically, we examined the mediating role of loneliness as measured in 1991 in the association between PTSD as measured in 1991 and marital adjustment as measured in 2003. Our sample consisted of 225 participants divided into 2 groups: ex-prisoners of war (ex-POWs) (N = 122) and a comparison group comprised of veterans who fought in the same war but who had not experienced captivity (N = 103). The findings demonstrate that ex-POWs display lower levels of marital adjustment and higher levels of PTSD than controls. Loneliness was found to mediate the relationship between PTSD as measured in 1991 and marital adjustment as measured in 2003 for both ex-POWs and controls. Further, for ex-POWs, loneliness contributes to marital adjustment above and beyond the contribution of PTSD as measured in 2003. The theoretical implications of loneliness for the marital relationships of traumatized ex-POWs are discussed.     

The relationship between posttraumatic stress disorder symptoms and paternal parenting of adult children among ex-prisoners of war: a longitudinal study

The aversive impact of combat and combat-induced posttraumatic stress disorder (PTSD) on parenting of young children has been examined in a few studies. Nevertheless, the toll of war captivity on parenting and the long-term relations between posttraumatic symptoms and paternal parenting of adult children remains unknown. This longitudinal study examined paternal parenting of adult children among war veterans, some of whom were held in captivity. Furthermore, we examined the mediating role of PTSD symptoms in the association between captivity and parenting. The sample included two groups of male Israeli veterans from the 1973 Yom Kippur War: ex-prisoners of war (ex-POWs) and comparable veterans who had not been held captive. Both groups were assessed via self-report measures of PTSD at three time points: Time 1 (18 after the war), Time 2 (30 after the war), and Time 3 (35 after the war) years after the war. Results shows that ex-POWs reported lower levels of positive parenting compared to comparison group veterans at Time 3. Furthermore, PTSD symptoms at Time 1, Time 2, and Time 3 mediated the association between captivity experience and parenting at Time 3. In addition, it was found that increases in the levels of PTSD symptom clusters over time were associated with lower levels of positive parenting at Time 3.     

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 Symptom Clusters,Trauma History,and Substance Use among College Students

Previous research found associations between experiencing specific posttraumatic stress disorder (PTSD) symptom clusters and use of specific substances among combat veterans, women exposed to domestic violence, and an inpatient sample; however, research has not utilized a college sample when considering this association. This study assessed trauma history, PTSD symptoms, alcohol use, and nonexperimental use of depressants, stimulants, opioids, cannabinoids, hallucinogens, inhalants, and steroids in college students. Results indicate unique associations between the PTSD symptom cluster of reexperiencing and use of depressants, avoidance/numbing with use of depressants and opiates, and hyperarousal with use of opiates. Further, the individual subclusters of behavioral avoidance and emotional numbing were associated with use of depressants and avoidance was associated with hallucinogen use. Implications are discussed.     

Posttraumatic Stress Disorder and Marital Adjustment: The Mediating Role of Forgiveness

The study assessed the effects of war captivity on posttraumatic stress symptoms and marital adjustment among Prisoners of War (POWs) from the Yom Kippur War. It was hypothesized that men's perception of level of forgiveness mediates the relation between posttraumatic symptoms and marital adjustment. The sample consisted of 157 Israeli veterans divided into 3 groups: 21 POWs with Posttraumatic Stress Disorder (PTSD), 58 former POWs without PTSD, and 70 control veterans. The findings indicated that former POWs with PTSD reported lower levels of marital satisfaction and forgiveness than veterans in the other 2 groups. In addition, men's perception of level of forgiveness mediated the relationship between their posttraumatic symptoms and their marital adjustment. The theoretical and clinical implications of these results are discussed.     

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.     

The cycle of violence as a function of PTSD and appetitive aggression: A longitudinal study with Burundian soldiers

During deployment, soldiers face situations in which they are not only exposed to violence but also have to perpetrate it themselves. This study investigates the role of soldiers' levels of posttraumatic stress disorder (PTSD) symptoms and appetitive aggression, that is, a lust for violence, for their engaging in violence during deployment. Furthermore, factors during deployment influencing the level of PTSD symptoms and appetitive aggression after deployment were examined for a better comprehension of the maintenance of violence. Semi-structured interviews were conducted with 468 Burundian soldiers before and after a 1-year deployment to Somalia. To predict violent acts during deployment (perideployment) as well as appetitive aggression and PTSD symptom severity after deployment (postdeployment), structural equation modeling was utilized. Results showed that the number of violent acts perideployment was predicted by the level of appetitive aggression and by the severity of PTSD hyperarousal symptoms predeployment. In addition to its association with the predeployment level, appetitive aggression postdeployment was predicted by violent acts and trauma exposure perideployment as well as positively associated with unit support. PTSD symptom severity postdeployment was predicted by the severity of PTSD avoidance symptoms predeployment and trauma exposure perideployment, and negatively associated with unit support. This prospective study reveals the importance of appetitive aggression and PTSD hyperarousal symptoms for the engagement in violent acts during deployment, while simultaneously demonstrating how these phenomena may develop in mutually reinforcing cycles in a war setting.     

The Relationship Between Posttraumatic Stress Symptoms and Suicide Ideation Among Child Survivors Following the Wenchuan Earthquake

The association between posttraumatic stress disorder (PTSD) symptoms and suicide ideation was examined in a sample of 2,298 child survivors of the Wenchuan earthquake. Results indicated that intrusion, avoidance, hyperarousal symptom clusters, and PTSD total score were significantly associated with suicide ideation. Except for intrusion, other measures of PTSD remained as statistically significant correlates of suicide ideation even after controlling for age, gender, direct exposure, indirect exposure, and depression. Furthermore, results showed that PTSD symptoms had an indirect influence on suicide ideation that was mediated by depression. The findings suggest that avoidance and hyperarousal symptom clusters of PTSD may be two important indicators of suicide ideation among child survivors of the Wenchuan earthquake. Implications of the results for intervention and prevention of suicide behavior are discussed.     

MMPI-2 as a predictor of change in PTSD symptom clusters: a further analysis of the Forbes et al. (2002) data set

In this study, we reanalyzed the Forbes et al. (2002) data set to examine the Minnesota Multiphasic Personality Inventory (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) as a differential predictor of change across posttraumatic stress disorder symptom clusters following treatment in 141 Vietnam veterans. A series of partial correlation and linear multivariate regression analyses, controlling for initial symptom severity, identified several scales predictive of symptom change. None of the MMPI-2 scales, however, emerged as predictors of change in reexperiencing symptoms. Social alienation and marital distress were the most potent predictors for avoidance symptoms. Anger, alcohol use, and hypomania were the most potent predictors for the hyperarousal symptoms. Of the personality disorders, borderline personality was the strongest predictor of change in the avoidance and hyperarousal clusters. Further replication of the findings of this article and those reported by Forbes et al. (2002) is required.     

Longitudinal Linkages Between Posttraumatic Stress Disorder Symptoms and Violent Behaviors Among Chinese Adolescents Following the Wenchuan Earthquake

This study was conducted to examine the longitudinal relations between posttraumatic stress disorder (PTSD) symptoms and violent behaviors. In this study, 415 adolescent survivors of the Wenchuan earthquake in China (May 12, 2008) were assessed by using self-report questionnaires 1 year (T1), 1.5 years (T2), and 2 years (T3) after the earthquake. The findings suggested that from 1 to 1.5 years after the earthquake, only intrusive symptoms of PTSD were a risk factor for violent behaviors, whereas violent behaviors were a risk factor for all 3 PTSD symptom clusters. Furthermore, 1.5 to 2 years after the earthquake, avoidance symptoms of PTSD were a risk factor for violent behaviors and hyperarousal symptoms of PTSD had no significant relation with violent behaviors.     

Posttraumatic stress and physical health among adults: The role of coping mechanisms

The purpose of the present study was to examine whether coping mechanisms predict physical health, after controlling for posttraumatic stress disorder (PTSD) symptom clusters in a non-clinical sample of adults. Data were collected from 483 adults through an online survey. Most of the participants (66.7%) reported lifetime exposure to at least one traumatic event. The final sample of this study included 319 trauma-exposed individuals. Results indicated that PTSD symptoms on the avoidance and hyperarousal clusters had significant positive relationships with self-reported physical health symptoms. After controlling for gender and PTSD, denial, behavioral disengagement, and self-blame significantly and positively predicted physical health symptoms.     

From front line to home front: a study of secondary traumatization.

While the long-term effects of combat trauma on veterans have been studied extensively, its impact on veterans' wives has yet to be investigated. This study examined the implications of combat-induced psychopathology--wartime combat stress reaction (CSR) and current posttraumatic stress disorder (PTSD)--in a sample of 205 wives of Israeli combat veterans of the 1982 Lebanon war. Results show that both CSR and PTSD were associated with increased psychiatric symptoms in the wives. In addition, current PTSD was particularly found to contribute to impaired social relations among veterans' wives in a broad range of contexts, from inner feelings of loneliness, through impaired marital and family relations, and extending to the wider social network. Implications of these findings for treatment and further research are discussed.     

Marital intimacy,family support,and secondary traumatization: A study of wives of veterans with combat stress reaction

Abstract

The main aim of the study was to assess the role of family variables in the process of secondary traumatization among wives of post-traumatic veterans. We compared a sample of 49 wives of Israeli veterans with combat stress reaction (CSR) from the 1982 Lebanon War with a sample of 31 wives of Israeli veterans who fought in the war without developing CSR. We assessed their psychological reactions to the war, their health status six years later, and their reported levels of marital intimacy and family support after the war. When compared with controls, wives of veterans with CSR reported more negative emotions and lower perceived intimacy after the war, and greater severity of psychiatric and somatic symptoms six years later. Results also indicate that the greater the perceived marital intimacy, the less the negative emotions wives of veterans with CSR felt after the war and the better their health status six years later. In addition, wives of veterans with CSR who reported having received more support from their families after the war reported more anxiety and hostility than wives who received less support. The roles of marital intimacy and family support in the process of secondary traumatization were discussed.     

Posttraumatic Stress Symptoms,Aggression, and Substance Use Coping among Young Adults

This study examined how the symptom clusters of posttraumatic stress disorder (PTSD) were related to substance use and self-reported aggression in a college sample. There were 358 participants (ages 18–24) who completed surveys to assess PTSD symptoms, substance use as coping, and aggression. Hierarchical regressions tested for the effects of PTSD symptoms (total symptoms as well as cluster symptoms) on self-reported aggression, along with the main and interaction effects of substance use coping on these relationships. The hyperarousal cluster of PTSD was the only group of symptoms significantly related to aggression. There was an interaction between avoidance symptoms and substance use coping on aggression such that under conditions of high substance use coping, aggression increased regardless of avoidance symptoms; however, the relationship between avoidance and aggression was stronger under conditions of low substance use coping, with greater aggression as avoidance symptoms and low substance use coping increased.     

Examination of the Relationship Between PTSD and Distress Tolerance in a Sample of Male Veterans With Comorbid Substance Use Disorders

Distress tolerance (DT), the perceived or actual ability to tolerate negative emotional or physical states, is inversely related to posttraumatic stress disorder (PTSD) symptoms in civilian, community samples. No studies to date have examined the relationship between DT and PTSD in clinical samples of veterans with a comorbid diagnosis of PTSD and a substance use disorder (SUD). Thus, the present study examined the relationship between DT and PTSD in a sample of predominately African American, male veterans (n = 75) diagnosed with comorbid PTSD and SUD (according to a structured clinical interview). Results of hierarchical linear regression models indicated that DT was inversely related to total PTSD symptom severity score, above and beyond depressive symptoms and SUD severity. Of the 4 symptom clusters, DT was inversely associated with intrusions and hyperarousal. These findings are discussed in light of previous work with civilian samples. Determining whether treatment incorporating DT skills would be useful for veterans undergoing PTSD treatment should be evaluated.     

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.     

Cross-Lagged Relationships Between Insomnia and Posttraumatic Stress Disorder in Treatment-Receiving Veterans

Insomnia is a risk factor for the development of posttraumatic stress disorder (PTSD) while it is also plausible that PTSD symptoms can maintain insomnia symptoms. The present study examined longitudinal bidirectional relationships between insomnia and PTSD symptoms in treatment-seeking veterans. Participants were 693 ex-serving members of the Australian Defence Force who participated in an accredited, hospital-based outpatient PTSD program. Participants completed self-reported assessments of PTSD and insomnia symptoms at four time points: intake, discharge, 3-month, and 9-months posttreatment follow-up.Cross-lagged pathway analyses indicated significant bi-directional pathways between insomnia symptoms and PTSD symptoms at most time points. A final cross-lagged model between insomnia symptoms and the PTSD symptom clusters indicated that the PTSD symptom paths on insomnia symptoms, between intake and discharge, were attributable to reexperiencing PTSD symptoms. In contrast, across posttreatment follow-up time points there were significant paths of insomnia symptoms on all PTSD symptom clusters except from insomnia at 3-months to avoidance symptom at 9-months. PTSD symptoms and insomnia symptoms have bidirectional associations over time that may lead to the mutual maintenance or exacerbation of each condition following PTSD treatment. Where residual insomnia symptoms are present post-treatment, a sleep-focussed intervention is indicated and a sequenced approach to treatment recommended.     

Influence of adjuvant mindfulness-based cognitive therapy (MBCT) on symptoms of post-traumatic stress disorder (PTSD) in veterans – results from a randomized control study

Even 30 or more years after the end of a war, veterans can suffer from post-traumatic stress disorder (PTSD). In the present study, we explored the influence on symptoms of PTSD among Iranian veterans of the Iran–Iraq war of mindfulness-based cognitive therapy (MBCT) as add-on to a standard treatment with citalopram. Forty-eight male veterans with PTSD (mean age: 52.97 years) took part in this eight-week intervention study. Standard treatment for all patients consisted of citalopram (30–50 mg/day at therapeutic dosages). Patients were randomly assigned either to the treatment or to the control condition. Treatment involved MBCT delivered in group sessions once a week. Patients in the control condition met at the hospital with the same frequency and duration for socio-therapeutic events. At baseline and at study completion, patients completed questionnaires covering symptoms of PTSD, depression, anxiety, and stress. At study completion after eight weeks, scores for PTSD (re-experiencing events, avoidance, negative mood and cognition, hyperarousal), depression, anxiety, and stress were lower, but more so in the intervention than the control group. Data suggest that, as adjuvant to standard SSRI medication, MBCT is an effective intervention to significantly reduce symptoms of PTSD, depression, anxiety, and stress among veterans.     

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.     

Associations between dimensions of anxiety sensitivity and PTSD symptom clusters in active-duty police officers

Prior studies have shown that anxiety sensitivity (AS) plays an important role in posttraumatic stress disorder (PTSD) symptom severity. The purpose of this study was to evaluate associations between empirically supported PTSD symptom clusters (i.e. reexperiencing, avoidance, numbing, hyperarousal) and AS dimensions (i.e. psychological concerns, social concerns, somatic concerns). Participants were 138 active-duty police officers (70.7% female; mean age = 38.9 years; mean time policing = 173.8 months) who, as a part of a larger study, completed measures of trauma exposure, PTSD symptoms, AS, and depressive symptoms. All participants reported experiencing at least one event that they perceived as traumatic, and 44 (31.9%) screened positive for PTSD. Officers with probable PTSD scored significantly higher on AS total as well as the somatic and psychological concerns dimensional scores than did those without PTSD. As well, a higher percentage of officers with probable PTSD scored positively on the AS-derived Brief Screen for Panic Disorder (Apfeldorf et al., 1994) compared with those without PTSD. A series of regression analyses revealed that depressive symptoms, number of reported traumas, and AS somatic concerns were significant predictors of PTSD total symptom severity as well as severity of reexperiencing. Avoidance was predicted by depressive symptoms and AS somatic concerns. Only depressive symptoms were significantly predictive of numbing and hyperarousal cluster scores. These findings contribute to understanding the nature of association between AS and PTSD symptom clusters. Implications for the treatment of individuals having PTSD with and without panic-related symptomatology are discussed.
