Complex trauma of war captivity: a prospective study of attachment and post-traumatic stress disorder

BACKGROUND: Victims of war captivity sometimes suffer from complex post-traumatic stress disorder (PTSD), a unique form of PTSD that entails various alterations in personality. These alterations may involve changes in attachment orientation.MethodThe sample comprised two groups of veterans from the 1973 Yom Kippur War: 103 ex-prisoners of war (ex-POWs) and 106 comparable control veterans. They were assessed at two points in time, 18 years and 30 years after the war. RESULTS: Ex-POWs suffered from more post-traumatic symptoms than controls at both measurements points and these symptoms increased only among ex-POWs from Time 1 to Time 2. In addition, both attachment anxiety and attachment avoidance increased with time among ex-POWs, whereas they decreased slightly or remained stable among controls. Finally, the increases in attachment anxiety and avoidance were positively associated with the increase in post-traumatic symptoms among both study groups. Further analyses indicated that early PTSD symptoms predicted later attachment better than early attachment predicted later PTSD symptoms. CONCLUSIONS: The results suggest that: (1) complex traumas are implicated in attachment orientations and PTSD symptoms even many years after captivity; (2) there is an increase in attachment insecurities (anxiety, avoidance) and an increase in PTSD symptoms decades after the captivity; (3) and post-traumatic stress symptoms predict attachment orientations better than attachment orientations predict an increase in PTSD symptoms.     

Auditory hallucinations and PTSD in ex-POWS

Literature has suggested that auditory hallucinations might be prevalent in the general population and could be linked to the experience of trauma. This prospective study examines the prevalence of auditory hallucinations in trauma survivors and its association with posttraumatic stress disorder (PTSD) symptoms, over time. Former prisoners of war (ex-POWs) from the 1973 Yom Kippur War (n = 99) with and without PTSD and comparable veterans (n = 103) were assessed twice, in 1991 (T1) and 2003 (T2) in regard to auditory hallucinations and PTSD symptoms. Findings indicated that ex-POWs who suffered from PTSD reported higher levels of auditory hallucinations at T2 as well as increased hallucinations over time, compared to ex-POWs without PTSD and combatants who did not endure captivity. The relation between PTSD and auditory hallucinations was unidirectional, so that the PTSD overall score at T1 predicted an increase in auditory hallucinations between T1 and T2, but not vice versa. Assessing the role of PTSD clusters in predicting hallucinations revealed that intrusion symptoms had a unique contribution, compared to avoidance and hyperarousal symptoms. The findings suggest that auditory hallucinations might be a consequence of the posttraumatic reaction among veterans.     

Symptoms of posttraumatic stress in parents of children with cancer: are they elevated relative to parents of healthy children?

Objective To examine posttraumatic stress symptoms (PTSS) inparents of children with cancer as a function of time sincediagnosis, treatment status, and relapse history, and as comparedto parents of healthy children. Method Participants includedparents of 199 children with cancer, comprising a cross-sectionalsample of diagnoses and treatment phases, ranging from currentlyon therapy to long-term survivors, and 108 parents of healthychildren obtained via acquaintance control methods. Parentscompleted a standardized self-report measure of PTSS. ResultsWithin the cancer group, parental report of PTSS differed asa function of treatment status and time since diagnosis. Parentsof children on active treatment endorsed similar levels of PTSSas control parents, whereas parents of children off treatmentreported significantly lower levels of PTSS than did controls.Similarly, parents of long-term survivors reported significantlylower levels of PTSS than did controls, while parents of recentlydiagnosed children did not differ from controls on PTSS. Incontrast, parents of children who had suffered a relapse reportedsignificantly higher levels of PTSS, and were much more likelyto be identified as a posttraumatic stress disorder (PTSD) case.Conclusions As a group, parents of children with cancer didnot demonstrate any evidence of increased PTSS relative to parentsof healthy children. Time since diagnosis, child treatment status,and relapse history are significant determinants of parent PTSS.Only parents of children who experienced a relapse appear tobe at increased risk of PTSD. The current results appear discrepantfrom the existing literature, and possible explanations forthese discrepancies are examined.     

Trajectories of attachment in older age: interpersonal trauma and its consequences

ABSTRACT

Previous studies suggest that attachment insecurities may increase after trauma exposure, an effect documented only at a group level. This study explores the heterogeneity of changes over time and examines the associations of the nature of the traumatic event (interpersonal and nonpersonal), and its consequences (posttraumatic stress disorder [PTSD] and loneliness) with attachment trajectories. Two groups of Israeli veterans participated: 164 former prisoners-of-war and 185 combat veterans. Attachment was assessed at four points (1991–2015). Risk factors were evaluated in 1991. Using latent growth mixture modeling, trajectories of attachment insecurities were explored. Three avoidance trajectories (stability, decrease, inverse u-shaped) and two anxiety trajectories (stability, decrease) were identified. The inverse u-shaped avoidance trajectory was associated with captivity, humiliation, loneliness, and PTSD, and stable avoidance was associated with loneliness. Stable anxiety was associated with captivity and loneliness. Attachment insecurities can change during aging and persist decades after a trauma. Trauma-related risk factors are related to more deleterious trajectories.     

Nonlinear relations between post-traumatic stress symptoms and electrocortical reactivity during emotional face processing in combat-exposed veterans

Combat-related post-traumatic stress symptoms (PTSS) are prevalent among recently deployed veterans, making identification of biomarkers of PTSS in this population a public health priority. Given the link between threat processing neurobiology and PTSS, the threat-related late positive potential (LPP), an ERP reflective of attentional processing sensitive to emotion and its regulation, may have utility as a cost-effective biomarker. Existing PTSS/threat-related LPP findings are mixed, possibly due to variability in PTSS across samples, but this has never been explicitly tested. To address this gap, LPP amplitudes to angry, fearful, and happy emotional face stimuli were recorded among 81 combat-exposed veterans at a VA hospital. A quadratic relationship between self-reported PTSS and LPP amplitude modulation by angry faces emerged such that greater PTSS was related to a decreased LPP response to angry faces among veterans with subthreshold PTSD and an enhanced LPP response to angry faces among veterans with probable PTSD. These results suggest that prior mixed findings may be due to variability in PTSS severity. In addition, exploratory moderation analysis revealed that PTSS was positively associated with late LPP modulation for veterans reporting low cognitive reappraisal use and negatively associated with late LPP modulation for veterans reporting high cognitive reappraisal use. All results were specific to the 1,000–3,000 ms LPP time window. Thus, the functional nature of LPP modulation by direct threat cues may depend upon PTSS severity and/or related variables (e.g., cognitive reappraisal utilization).     

Brief report: post-traumatic stress during emerging adulthood in survivors of pediatric cancer

OBJECTIVE: To examine post-traumatic stress symptoms (PTSS) and disorder (PTSD) among survivors of childhood cancer and comparison peers during the transition to emerging adulthood. METHOD: From elementary and middle school, we prospectively followed a cohort of 56 cancer survivors, 60 comparison peers, and their parents. Assessments were completed after the youth's 18th birthday using questionnaires and a semi-structured psychiatric interview. Healthcare providers rated treatment severity and late effects. RESULTS: Survivors and comparison peers did not differ on rates of PTSS or PTSD, but comparison peers reported more dissociative experiences than survivors. Late effects were associated with a greater number of past PTSS. Of the 16 cancer survivors who reported a traumatic event, five (31%) were cancer-related. CONCLUSIONS: Levels of PTSS were similar for survivors and comparison peers. Research with other potentially traumatic diseases or treatments (e.g., amputations, brain tumors) is needed. The role of methodology and contextual factors in the assessment of PTSS/PTSD is discussed.     

Twofold trauma exposure – the dual function of attachment avoidance

Spouses of traumatized war veterans might suffer from distress following indirect exposure to combat and direct exposure to domestic abuse. Yet the effect of this twofold trauma exposure is far from being fully understood. Theory views attachment security as a personal resource mitigating adversity, whereas attachment insecurities intensify distress. Nevertheless, there are mixed results concerning the effects of attachment in the aftermath of trauma. Furthermore, the role of trauma exposure levels regarding the effects of attachment remains largely uninvestigated. Filling these gaps, this study assessed female military spouses 30 (T1) and 38 (T2) years after the 1973 Yom Kippur War. Direct (domestic abuse) and indirect (veteran partners’ posttraumatic stress symptoms) trauma exposure, attachment, depression, and anxiety were assessed. Findings indicated an interaction between the trauma types in predicting spouses’ anxiety. Domestic abuse moderated the relations between attachment and distress. Although attachment anxiety had nonsignificant effects on anxiety among low-level domestic abuse sufferers, it predicted elevated anxiety among high-level domestic abuse sufferers. Furthermore, while attachment avoidance predicted elevated distress among low-level domestic abuse sufferers, its effects dissolved or became positive in nature among high-level domestic abuse sufferers. Discussion focuses on evolutionary explanations of the functions of attachment under different conditions of threat.     

Post-traumatic stress symptoms in an elite unit of Brazilian police officers: prevalence and impact on psychosocial functioning and on physical and mental health

BACKGROUND: Frequent exposure to traumatic situations put police officers under an increased risk for developing post-traumatic stress disorder (PTSD). The goals of this study were to determine the current prevalence of post-traumatic stress symptoms (PTSS) in Brazilian police officers and to compare groups with and without PTSS in terms of associated morbidity. METHODS: Police officers from an elite unit (n=157) were asked to fill out a socio-demographic questionnaire, the 12-item General Health Questionnaire and the Post-Traumatic Stress Disorder Checklist-Civilian Version. The latter's scores were used to establish the diagnoses of "full PTSD" and of "partial PTSD". RESULTS: Prevalence rates of "full PTSD" and "partial PTSD" were 8.9% and 16%, respectively. Compared with the "no PTSD" group, police officers with "full PTSD" were five times more likely to be divorced (21.6% vs. 4.3%, p=0.008), felt that their physical health was poorer (64.3% vs. 6%, p<0.001), had more medical consultations during the last 12 months [2.00 (+/-1.62) vs. 1.09 (+/-1.42), p=0.03] and reported more often lifetime suicidal ideation (35.7% vs. 5.2%, p=0.002). LIMITATIONS: The sample was relatively small. A screening tool was employed instead of a semi-structured interview. The cross-sectional design is unsuitable for ascertaining cause-effect relations. CONCLUSIONS: PTSD prevalence in our sample was comparable to those reported for North American and Dutch policemen. The presence of "full PTSD" was associated with evidences of considerable morbidity. These findings may contribute to the development of effective policies aimed at the prevention and treatment of PTSD in law enforcement agents.     

Effects of posttraumatic stress disorder status and covert hostility on cardiovascular responses to relived anger in women with and without PTSD

Previous literature has found greater heart rate (HR) and blood pressure (BP) responses during relived anger, and a positive association between covert hostility and relived anger, in male veterans with posttraumatic stress disorder (PTSD). This study investigated hostility and cardiovascular responses to a relived anger task in 120 women (70 with PTSD and 50 without PTSD). Women with PTSD reported greater hostile beliefs and covert hostility than non-PTSD controls, reported greater anger and anxiety during the anger recall task, and had higher resting HR. In general, the relationship between PTSD and cardiovascular response was moderated by covert hostility, which was associated with greater baseline diastolic BP and greater HR during relived anger and anger recovery among women with PTSD, but not among non-PTSD controls. Results suggest that the relationship between PTSD and cardiovascular response is moderated by hostility.

The long-term implications of war captivity for mortality and health

The current study aims to (1) assess the long-term impact of war captivity on mortality and various health aspects and (2) evaluate the potential mediating role of posttraumatic stress disorder (PTSD) and depressive symptoms. Israeli ex-prisoners of war (ex-POWs) (N = 154) and a matched control group of combat veterans (N = 161) were assessed on health conditions and self-rated health 18 years post-war (1991: T1). The whole population of ex-POWs, and the T1 sample of controls were then contacted 35 years after the war (2008: T2), and invited to participate in a second wave of measurement (ex-POWs: N = 171; controls: N = 116) Captivity was implicated in premature mortality, more health-related conditions and worse self-rated health. PTSD and depressive symptoms mediated the relationship between war captivity and self-rated health, and partially mediated the relationship between war captivity and health conditions, and these effects were amplified with age. Aging ex-POWs who develop psychiatric symptomatology should be considered a high-risk group entering a high-risk period in the life cycle. It is important to monitor ex-POWs and provide them with appropriate medical and psychological treatment as they age.     

Smoking, traumatic event exposure, and post-traumatic stress: a critical review of the empirical literature

The current review critically examines the extant empirical literature focused on the associations among cigarette smoking, trauma, and post-traumatic stress. Inspection of the extant literature suggests that smoking rates are significantly higher among persons exposed to a traumatic event relative to those without such exposure. Moreover, smoking rates appear particularly high among persons with post-traumatic stress disorder (PTSD). In terms of the direction of this relation, evidence most clearly suggests that post-traumatic stress is involved in the development of smoking. Significantly less is known about the role of trauma and PTSD in terms of cessation outcome. Limitations of extant work, clinical implications, and key directions for future study are delineated.     

Late-onset PTSD in unaccompanied refugee minors: exploring the predictive utility of depression and anxiety symptoms

Following resettlement in Western countries, unaccompanied refugee minors (URM) are at risk of developing posttraumatic stress disorder (PTSD). It is unclear to what extent PTSD in this group may become manifest at later stages following resettlement and which factors are associated with late onset. We examined data from URM collected 1 (T1) and 2 years (T2) following resettlement for differences between groups with no PTSD, PTSD at T1, and late-onset PTSD (at T2 only) using multinomial regression and path analysis. Of the children and adolescents (ages 12-18) completing both assessments (N = 554), 223 (40%) met criteria for PTSD at T1, and 88 (16%) endorsed late-onset PTSD. Late-onset PTSD was associated with traumatic event exposure, older age, and low education. In the late-onset PTSD group, the predictive effects of traumatic event exposure on symptom severity at T2 were fully mediated by depression and anxiety symptoms at T1. These results suggest that late-onset PTSD is a clinically relevant problem among URM that may be heralded by early depression and anxiety symptoms.     

Adult attachment insecurities are associated with obsessive compulsive disorder

Objectives. Obsessive compulsive disorder (OCD) is one of the most disabling and highly prevalent anxiety disorders (ADs). Current cognitive models of OCD implicate views about the self and world in the maintenance of the disorder. However, little research has focused on issues that may lead to vulnerability to such views. In particular, a person's attachment insecurities (attachment anxiety, avoidance) may be important risk factors increasing the likelihood of such non-adaptive perceptions (Doron & Kyrios, 2005). Design. Participants meeting criteria for OCD were compared with cohorts meeting criteria for other ADs and healthy controls on a range of measures including adult attachment, OC symptoms, cognitions, and mood. Methods. Diagnosis of the clinical groups was established using the Anxiety Disorders Interview Schedule for DSM-IV (Brown, Di Nardo, & Barlow, 1994). The clinical relevance of attachment insecurities was ascertained by comparing their prevalence in an OCD sample (N= 30), an ADs sample (N= 20), and a community sample (N= 32). Results. Attachment anxiety was significantly higher in individuals with OCD, even when controlling for depression. Conclusions. Addressing attachment anxiety in individuals presenting with OCD may be important for enhancing therapeutic outcomes. However, findings are based on cross-sectional data that preclude conclusions relating to causal influence.

PTSD after traumatic injury: an investigation of the impact of injury severity and peritraumatic moderators

Presence of injury is often examined as a risk factor for posttraumatic stress disorder (PTSD); however, results have been mixed regarding the relationship between injury severity and PTSD symptoms (PTSS). The present study examined subjective and objective injury severity ratings in traumatic injury victims to determine if they differentially predict PTSS. Results demonstrated that subjective, not objective, injury severity predicted PTSS at six weeks and three months post-trauma. The moderating impact of peritraumatic factors was also examined. Peritraumatic dissociation moderated the impact of subjective injury severity on PTSS. Findings indicate that subjective injury severity should be incorporated into early screeners for PTSD risk.     

The role of psychological symptoms and social group memberships in the development of post-traumatic stress after traumatic injury

Objectives. The costs associated with traumatic injury are often exacerbated by the development of post-traumatic stress symptoms. However, it is unclear what decreases the development of post-traumatic symptoms over time. The aim of the present research was to examine the role of psychological symptoms and social group memberships in reducing the development of post-traumatic stress symptoms after orthopaedic injuries (OIs) and acquired brain injuries (ABIs). Design and Methods. A longitudinal prospective study assessed self-reported general health symptoms, social group memberships, and post-traumatic stress symptoms among participants with mild or moderate ABI (n= 62) or upper limb OI (n= 31) at 2 weeks (T1) and 3 months (T2) after injury. Results. Hierarchical regressions revealed that having fewer T1 general health symptoms predicted lower levels of T2 post-traumatic stress symptoms after OI but forming more new group memberships at T1 predicted lower levels of T2 post-traumatic stress symptoms after ABI. Conclusion. A focus on acquiring group memberships may be particularly important in reducing the development of post-traumatic stress symptoms after injuries, such as ABI, which result in long-term life changes. STATEMENT OF CONTRIBUTION: WHAT IS ALREADY KNOWN ON THIS SUBJECT?: ? Post-traumatic stress symptoms are a common outcome after accidental traumatic injury. ? Persistent post-traumatic stress symptoms can be a risk factor for the development of PTSD. WHAT DOES THIS STUDY ADD?: ? New insight into the contributions of general health symptoms and social group memberships in the development of post-traumatic stress symptoms after accidental injury. ? The development of post-traumatic stress symptoms over time is associated with higher levels of general health symptoms among individuals with orthopaedic injuries; They are associated with lower levels of social group memberships among individuals with acquired brain injuries.     

Tribulin in post-traumatic stress disorder

Tribulin (endogenous monoamine oxidase inhibitor/benzodiazepine receptor binding inhibitor) output was measured in the urine of 18 patients with post-traumatic stress disorder (PTSD) and 13 controls. The level of the two inhibitory activities was highly significantly correlated in the group as a whole. There was no difference between output of either inhibitor in patients and controls. However, when the PTSD group was subdivided according to various psychometric ratings, a pattern of output did emerge. Levels of both inhibitory activities were higher in agitated compared with non-agitated subjects, and lower in extroverts compared with introverts. This finding supports the view that tribulin output is raised in conditions of greater arousal.     

Serum cholesterol,uric acid and cholinesterase in victims of the Tokyo subway sarin poisoning: a relation with post-traumatic stress disorder

Cholesterol and uric acid, which might correlate with steroidogenesis and monoamine functions, may change under emotionally stressful conditions and in mental disturbances. Among anxiety disorders, an increase of serum cholesterol has been observed in panic disorder. However, the issue has not been adequately investigated in other anxiety disorders, including post-traumatic stress disorder (PTSD). The present study investigated serum cholesterols, uric acid and cholinesterase in victims of the Tokyo subway sarin poisoning, 1995, in a series of 5-year follow-ups. Cholinesterase was studied, in relevance with serum lipid changes and symptoms of PTSD, and also in light of a biological effect of sarin. Out of 34 victims, eight developed PTSD and two were currently diagnosed with PTSD using the Clinician-Administered PTSD Scale (CAPS). No significant relationship was observed between PTSD and serum cholesterols or uric acid. Several factors including co-occurrence of other mental disturbances with PTSD, in addition to the limited sample size, might have affected the result. In contrast, serum cholinesterase level was significantly reduced in the victims with the development of PTSD, compared with the matched controls (P<0.02, t-test). This might partly reflect a long-term remnant effect of sarin intoxication, although an effect of the psychological experience could not be totally excluded.     

Family and past history of mental illness as predisposing factors in post-traumatic stress disorder

BACKGROUND: Family studies of post-traumatic stress disorder (PTSD) have given inconsistent results to date. Identifying predisposing factors in PTSD compared to anxiety disorders may help to clarify the classification of PTSD as a diagnostic entity. METHOD: Retrospective case note study of 87 PTSD patients who participated in an RCT, and 51 PTSD patients and 87 agoraphobics treated routinely in outpatients. RESULTS: Compared to agoraphobics, PTSD patients had significantly less family history of anxiety disorder but not mental illness in general. They also had significantly less personal history of mental illness prior to the index episode. CONCLUSIONS: Trauma precipitated PTSD in subjects who had significantly fewer premorbid predisposing factors than did agoraphobics. Such factors may predispose agoraphobics to become psychiatrically ill after more minor trauma. Research is needed to systematically compare the events which precipitate PTSD as opposed to agoraphobia and other anxiety disorders.
