The relationship of PTSD to negative cognitions: a 17-year longitudinal study

With the growing interest in the role of cognitions in PTSD, this prospective study examined the course and bi-directional relationship between post-trauma cognitions and symptoms of PTSD. A sample of Israeli combat veterans, including former prisoners of war, was assessed in 1991, and later followed up in 2003 and 2008. PTSD symptoms were measured at three time points. Cognitions concerning the self and the world were measured twice. Applying autoregressive cross-lagged (ARCL) modeling strategy, initial PTSD symptoms predicted subsequent negative cognitions but not vice versa. In addition, repeated measures design revealed that individuals with chronic PTSD symptoms had relatively negative cognitions that further amplified with time. More specifically, increasingly negative cognitions were documented among ex-prisoners of war. The main findings suggest that negative cognitions are fueled by PTSD and that in chronic PTSD there is an amplification of pathogenic outcomes over time. Discussion of the findings is in the context of current cognitive models of PTSD.

PTSD, resilience and posttraumatic growth among ex-prisoners of war and combat veterans

BACKGROUND

Past studies have shown that adversity may yield various salutogenic outcomes. two constructs that have been at the center of this scientific investigation are resilience and posttraumatic growth (PTG). the present study aims to clarify the relations between posttraumatic stress symptoms, resilience and PTG among israeli war veterans.

METHOD

the sample includes former prisoners of war (ex-POWs) (n=103) and comparable veterans (n=106) of the 1973 Yom Kippur War. the veterans were assessed twice: 18 and 30 years after the war with self-report questionnaires.

RESULTS

resilience, defined as the absence of posttraumatic symptoms, and PTG are negatively correlated. resilient ex- POWs and veterans reported the lowest levels of PTG when compared to participants diagnosed with clinical and sub-clinical posttraumatic stress disorder (PtSd). Furthermore, PTG dimensions were found to be the most differentiating factor between study groups, followed by war exposure measures and clinical reports of depression and anxiety symptoms.

CONCLUSIONS

this study strengthens the understanding that combatants who report high-level PtSd symptoms also report higher levels of positive psychological changes in the face of severe adversity.

The utility of Criterion A under chronic national terror

According to DSM-IV-TR, both an objective and a subjective exposure component (A1 and A2 criteria, respectively) are required in order to qualify for a Posttraumatic stress Disorder (PTSD) diagnosis. one proposed DSM-5 change is that Criterion A be more explicitly defined and made purely objective. the DSM and the ICD appear to be largely products of the north american and european societies and, therefore, may be culturally-biased. Compared with other societies, the latter are not exposed to chronic national traumatic stress. therefore, the current structure of Criterion A may be especially relevant to single traumatic incidents, rather than to chronic national scale. the current review raises the question of whether the proposed DSM-5 changes to Criterion A are congruent with the reality of nations where exposure to terror is persistent, constant and of national proportions.

Elaboration on posttraumatic stress disorder diagnostic criteria: a factor analytic study of PTSD exposure to war or terror

BACKGROUND

In societies facing prolonged exposure to war and terror, empirical research provides mixed support for the posttraumatic stress disorder (PTSD) symptom clusters groupings identified by the Diagnostic and Statistical Manual (DSM-IV-TR) as re-experiencing the event, avoidance and emotional numbing, and hyperarousal.

METHOD

This study examines the validity of the PTSD symptom clusters in elements of Israeli society exposed to man-made trauma. Survivors (N=2,198) of seven different war and terror-related traumas were assessed using a DSM-IV-TR based PTSD inventory. Four confirmatory factor analytic models were compared.

RESULTS/CONCLUSIONS

The most acceptable model was a correlated model consisting of four factors of re-experiencing, avoidance, emotional numbing, and hyperarousal. DSM-IV-TR avoidance empirically split into active avoidance and emotional numbing. These results corroborate knowledge and suggest that in Israel, where stressors are ongoing, the PTSD symptom clusters may be reformulated in DSM-5 to consist of re-experiencing, active avoidance, emotional numbing and hyperarousal.

Predictors of PTSD trajectories following captivity: a 35-year longitudinal study

Although war captivity is a potent pathogen for psychiatric illness, little is known about the long-term trajectories of post-traumatic stress disorder (PTSD) among ex-prisoners of wars (ex-POWs). This study aimed to assess the long-term trajectories of PTSD and their predictors following war captivity. Three follow-ups (1991, 2003, 2008) were conducted over 35 years of 164 Israeli ex-POWs and185 comparable combatants from the 1973 Yom Kippur War. Ex-POWs reported higher PTSD rates than controls at all three assessments. Four trajectories of PTSD were identified: chronic PTSD, delayed PTSD, recovery and resilience. The majority of POWs reported delayed PTSD, while the majority of controls were classified as resilient. While PTSD rates remained relatively stable over time among controls, a steep increase in rates was observed among POWs between 1991 and 2003, followed by stabilization in rates between 2003 and 2008. Finally, subjective experience of captivity was the variable that best distinguished between the resilience and PTSD groups of ex-POWs, followed by participation in previous wars and negative life events during childhood. War captivity carries long-lasting psychiatric implications, even decades after release. Aging processes, as well as unique stressors that exist in Israel, may account for the elevated PTSD rates found here.

Coping strategies of Ethiopian immigrants in Israel: association with PTSD and dissociation

The aim of this study was to examine the relations between coping strategies, posttraumatic stress disorder (PTSD), and dissociation among Jewish Ethiopian refugees in Israel (following exposure to pre-, peri- and post-migration stressful events).

METHOD

A random sample (N = 478) of three waves of refugees took part in the research (N = 165; N = 169; N = 144). Religiosity, coping strategies, stressful and traumatic events, pre- and peri- migration, post-migration difficulties, posttraumatic symptoms, and dissociation were assessed.

RESULTS

A significant relationship was found between PTSD symptoms and avoidance coping over and above immigration wave and traumatic events. Dissociation was positively associated with passivity and antisocial coping and negatively associated with social joining and level of religiosity, over and above immigration wave and traumatic events. The findings are discussed in the light of the coping strategies employed by Ethiopian refugees.

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.

Coerced hospital admission and symptom change--a prospective observational multi-centre study

INTRODUCTION

Coerced admission to psychiatric hospitals, defined by legal status or patient's subjective experience, is common. Evidence on clinical outcomes however is limited. This study aimed to assess symptom change over a three month period following coerced admission and identify patient characteristics associated with outcomes.

METHOD

At study sites in 11 European countries consecutive legally involuntary patients and patients with a legally voluntary admission who however felt coerced, were recruited and assessed by independent researchers within the first week after admission. Symptoms were assessed on the Brief Psychiatric Rating Scale. Patients were re-assessed after one and three months.

RESULTS

The total sample consisted of 2326 legally coerced patients and 764 patients with a legally voluntary admission who felt coerced. Symptom levels significantly improved over time. In a multivariable analysis, higher baseline symptoms, being unemployed, living alone, repeated hospitalisation, being legally a voluntary patient but feeling coerced, and being initially less satisfied with treatment were all associated with less symptom improvement after one month and, other than initial treatment satisfaction, also after three months. The diagnostic group was not linked with outcomes.

DISCUSSION

On average patients show significant but limited symptom improvements after coerced hospital admission, possibly reflecting the severity of the underlying illnesses. Social factors, but not the psychiatric diagnosis, appear important predictors of outcomes. Legally voluntary patients who feel coerced may have a poorer prognosis than legally involuntary patients and deserve attention in research and clinical practice.

Predictors for Poststroke Outcomes: The Tel Aviv Brain Acute Stroke Cohort (TABASCO) Study Protocol

Background

Recent studies have demonstrated that even survivors of mild stroke experience residual damage, which persists and in fact increases in subsequent years. About 45% of stroke victims remain with different levels of disability. Identifying factors associated with poststroke cognitive and neurological decline could potentially yield more effective therapeutic opportunities.

Aims and hypothesis

We hypothesize that data based on biochemical, neuroimaging, genetic and psychological measures can, in aggregate, serve as better predictors for subsequent disability, cognitive and neurological deterioration, and suggest possible interventions.

Design

The Tel-Aviv Brain Acute Stroke Cohort (TABASCO) study is an ongoing, prospective cohort study that will recruit approximately 1125 consecutive first-ever mild–moderate stroke patients. It is designed to evaluate the association between predefined demographic, psychological, inflammatory, biochemical, neuroimaging and genetic markers, measured during the acute phase, and long-term outcome: subsequent cognitive deterioration, vascular events (including recurrent strokes), falls, affect changes, functional everyday difficulties and mortality.

Discussion

This study is an attempt to comprehensively investigate the long-term outcome of mild–moderate strokes. Its prospective design will provide quantitative data on stroke recurrence, the incidence of other vascular events and the evaluation of cognitive, affective and functional decline. Identifying the factors associated with poststroke cognitive and functional decline could potentially yield more effective therapeutic approaches.

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.

The role of religious orientations in youth's posttraumatic symptoms after exposure to terror

This study examined the effect of religiosity on youth's posttraumatic symptoms resulting from exposure to terror. Participants consisted of 1,973 Israeli high school students. Objective and subjective exposure (fear) to terror were positively associated with posttraumatic symptoms. Intrinsic religiosity was negatively associated with posttraumatic symptoms and found to decrease the effects of objective exposure. Personal extrinsic orientation and social extrinsic orientation were positively associated with posttraumatic symptoms, having no mediating effect. Theoretical implications regarding religiosity as a coping mechanism in light of exposure to terror are discussed.

Delayed-onset PTSD among war veterans: the role of life events throughout the life cycle

BACKGROUND

The underlying mechanisms of delayed-onset PTSD are yet to be understood. This study examines the role of stressful life events throughout the life cycle in delayed-onset PTSD following combat.

METHODS

675 Israeli veterans from the 1982 Lebanon War, 369 with antecedent combat stress reaction (CSR) and 306 without CSR were assessed prospectively, 1, 2 and 20 years after the war. Veterans were divided into four groups, according to the time of first PTSD onset (first onset at 1983, 1984, and 2002 and no PTSD onset). They were assessed for post-, peri- and pre-traumatic life events, as well as military and socio-demographic characteristics.

RESULTS

Our findings indicate that shorter delays in PTSD onset were associated with a higher risk for CSR, a higher number of pre- and post-war life events, more severe subjective battle exposure, greater perceived danger during combat and a more stressful military position. CSR was found to be the most powerful predictor of PTSD onset. A recency effect was also found, with more recent life events proving to be stronger predictors of PTSD onset.

CONCLUSIONS

First, our findings validate the existence of delayed-onset PTSD, as it was found among a substantial number of participants (16.5%). Second, post-, peri- and pre-traumatic life events are associated with the time of PTSD onset. Thus, practitioners and researchers are encouraged to examine not only the original trauma, but also the stressful experiences throughout the survivors' life cycle. In particular, identification of antecedent CSR may help mental help professionals in targeting high-risk populations.

Development and Validation of the Coping With Terror Scale

Terrorism creates lingering anxiety about future attacks. In prior terror research, the conceptualization and measurement of coping behaviors were constrained by the use of existing coping scales that index reactions to daily hassles and demands. The authors created and validated the Coping with Terror Scale to fill the measurement gap. The authors emphasized content validity, leveraging the knowledge of terror experts and groups of Israelis. A multistep approach involved construct definition and item generation, trimming and refining the measure, exploring the factor structure underlying item responses, and garnering evidence for reliability and validity. The final scale comprised six factors that were generally consistent with the authors’ original construct specifications. Scores on items linked to these factors demonstrate good reliability and validity. Future studies using the Coping with Terror Scale with other populations facing terrorist threats are needed to test its ability to predict resilience, functional impairment, and psychological distress.

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.

Trajectories of stress reactions and somatization symptoms among war veterans: a 20-year longitudinal study

BACKGROUND

There is considerable evidence that immediate and long-term stress reactions are associated with increased somatic symptomatology. However, because of the scarcity of long-term longitudinal studies, the trend of mutual change of these factors has not been assessed. This study examined the chronological inter-relationships between post-traumatic stress reactions and somatization symptoms among combatants over a 20-year period.

METHOD

Two groups of veterans were assessed 1, 2, 3 and 20 years after their participation in the 1982 Lebanon War: a clinical group of veterans who had been diagnosed with combat stress reaction (CSR) on the battlefield (n=363), and a matched control group of veterans (n=301).

RESULTS

The CSR veterans reported higher initial levels of intrusion and avoidance and a steeper decline in those symptoms over time in comparison to the control group. The former also reported higher initial levels of somatization symptoms than the latter. In addition, over the years, stress reactions were positively associated with somatization symptoms. For both study groups, in the first years after the war, stress reaction symptoms predicted somatization symptoms. However, with time, the trend was reversed and somatization symptoms predicted stress reactions.

CONCLUSIONS

The findings suggest that CSR is a marker for future stress reactions and somatization symptoms, and indicate a long-term role for these symptoms in veterans' psychological distress.

Comorbidity of posttraumatic stress disorder, anxiety and depression: a 20-year longitudinal study of war veterans

BACKGROUND

This study aims to: (a) follow-up the prevalence of comorbidity of posttraumatic stress disorder (PTSD), anxiety and depression; (b) determine the chronological relations between these disorder; and (c) examine whether PTSD comorbid with anxiety and depression is implicated in more impaired functioning than PTSD by itself.

METHODS

664 war veterans were followed up 1, 2, and 20 years after their participation in the 1982 Lebanon War. Comorbidity was assessed by self reported PTSD, anxiety, and depression symptoms; impairment in psychosocial functioning was assessed by self reported problems in occupational, social, sexual and family functioning.

RESULTS

At each point of assessment, rates of triple comorbidity (PTSD, anxiety and depression; 26.7-30.1%) were higher than rates of PTSD, either by itself (9.3-11.1%), or comorbid with depression (1.2-4.5%) or anxiety (2.9-4.5%). PTSD predicted depression, anxiety, and comorbid disorders, but not vice versa. At time 1 and 2 assessments, triple comorbidity was associated with more impaired functioning than PTSD alone. In addition, triple comorbidity at Time 2 was associated with more impaired functioning than double comorbidity.

LIMITATIONS

Since measurements did not cover the entire span of 20 years since the war, the entire spectrum of changes could not be monitored.

CONCLUSIONS

Almost one half of war veterans would endorse a lifetime triple comorbidity, and those who do, are likely to have more impaired functioning. The findings support the perspective that views PTSD as the dominant disorder following traumatic events, which impels the development of comorbid anxiety and depression.

Elaboration on posttraumatic growth in youth exposed to terror: the role of religiosity and political ideology

OBJECTIVES

This study aims to examine competing explanations of the relationship between religious and political ideology commitment with posttraumatic growth.

METHOD

Subjects were Israeli youth who were exposed to terror (n = 2,999) aged 13-15. Measures included: posttraumatic growth inventory, religious orientation, ideological commitment, objective and subjective exposure to terror.

RESULTS

Both religiosity and political ideology mediated the effects of exposure and fear on growth. Political ideology but not religiosity, had a moderating effect, such that subjective fear was positively associated with growth only among those with stronger ideologies.

CONCLUSION

Results support the contention of Terror Management Theory that cultural beliefs have beneficial effects on well being in the face of adversity and emphasize the role of cultural world as effecting growth, beyond trauma.

Patients' views of involuntary hospital admission after 1 and 3 months: prospective study in 11 European countries

BACKGROUND

Legislation and practice of involuntary hospital admission vary substantially among European countries, but differences in outcomes have not been studied.

AIMS

To explore patients' views following involuntary hospitalisation in different European countries.

METHOD

In a prospective study in 11 countries, 2326 consecutive involuntary patients admitted to psychiatric hospital departments were interviewed within 1 week of admission; 1809 were followed up 1 month and 1613 3 months later. Patients' views as to whether the admission was right were the outcome criterion.

RESULTS

In the different countries, between 39 and 71% felt the admission was right after 1 month, and between 46 and 86% after 3 months. Females, those living alone and those with a diagnosis of schizophrenia had more negative views. Adjusting for confounding factors, differences between countries were significant.

CONCLUSIONS

International differences in legislation and practice may be relevant to outcomes and inform improvements in policies, particularly in countries with poorer outcomes.

Combat exposure, posttraumatic stress symptoms and risk-taking behavior in veterans of the Second Lebanon War

Prior research has revealed heightened risk-taking behavior among veterans with posttraumatic stress disorder (PTSD). This study examined whether the risktaking behavior is a direct outcome of the traumatic exposure or whether this relationship is mediated by posttraumatic stress symptoms. The sample was comprised of 180 traumatized Israeli reserve soldiers, who sought treatment in the wake of the Second Lebanon War. Combat exposure was indirectly associated with risk-taking behavior primarily through its relationship with posttraumatic stress symptoms. Results of the multivariate analyses depict the implication of posttraumatic stress symptoms in risk taking behavior, and the role of self-medication and of aggression in traumatized veterans.

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.
