Posttraumatic stress disorder and psychosocial functioning within two samples of MVA survivors

To examine criterion F variables of PTSD, the psychosocial functioning of two samples of motor vehicle accident (MVA) survivors was investigated. Within each sample, comparisons between MVA survivors with and without PTSD were conducted on four psychosocial functioning indices at three time points. In addition, the relationships between specific PTSD symptom clusters and psychosocial functioning indices were examined. The study revealed that, in general, MVA survivors with PTSD evidenced poorer psychosocial functioning than did survivors without PTSD. The emotional numbing symptoms of PTSD emerged as the most consistent predictors of the psychosocial functioning indices. The implications of these findings to the comprehensive treatment of PTSD are discussed.     

Enhanced priming for trauma-related words predicts posttraumatic stress disorder

There is preliminary evidence that enhanced priming for trauma-related cues plays a role in posttraumatic stress disorder (PTSD). A prospective study of 119 motor vehicle accident survivors investigated whether priming for trauma-related stimuli predicts PTSD. Participants completed a modified word-stem completion test comprising accident-related, traffic-related, general threat, and neutral words at 2 weeks post-trauma. Priming for accident-related words predicted PTSD at 6 months follow-up, even when initial symptom levels of PTSD and depression and priming for other words were controlled. The results are in line with the hypothesis that enhanced priming for traumatic material contributes to the development of chronic PTSD.     

Impact of emotional approach coping and hope on PTSD and depression symptoms in a trauma exposed sample of Veterans receiving outpatient VA mental health care services

The present investigation evaluates the relationship between coping style, dispositional hope, and posttraumatic stress disorder (PTSD) and depression symptom severity in a trauma-exposed Veteran sample. Specifically, we evaluated the adaptive value of emotional avoidant and approach coping strategies and perceptions of hope in a sample of 209 trauma-exposed Veterans receiving outpatient mental health care at a VA facility. Participants completed a life events questionnaire and inventories assessing coping, dispositional hope, and PTSD and depression symptom severity. Hierarchical regression analyses were conducted controlling for relevant demographic variables. Greater levels of emotional avoidance and lower levels of emotional expression were significantly associated with increased PTSD and depression symptom severity. Dispositional hope was positively associated with depression symptoms only and perceptions of hope moderated the association between emotional avoidance coping and depression symptoms. Findings highlight the value of emotional coping strategies and perceptions of hope in posttraumatic adjustment. Specifically, employing coping techniques that encourage emotional expression may promote improved adjustment among trauma-exposed individuals, while reduced perceptions of hope and the use of avoidant coping strategies may place individuals at greater risk for depression following exposure to traumatic events.

The impact of depression and PTSD symptom severity on trauma memory

Posttraumatic stress disorder (PTSD) and depression frequently co-occur following a traumatic event. Differences in the processing of autobiographical memory have been observed in both disorders in the form of overgeneralised memories and negative intrusive memories. The current study examined how symptoms of PTSD and depression influence the phenomenological characteristics of trauma memories. Undergraduate students who had experienced a traumatic event (n?=?696) completed questionnaires online including measures of PTSD and depressive symptom severity. They rated their trauma memory on several phenomenological characteristics using the Memory Experiences Questionnaire [Sutin, A. R., &; Robins, R. W. (2007). Phenomenology of autobiographical memories: The memory experiences questionnaire. Memory.]. Moderated multiple regression was used to examine how PTSD and depressive symptom severity related to each phenomenological characteristic. Symptoms of PTSD and depression were related separately and uniquely to the phenomenological characteristics of the trauma memory. PTSD severity predicted trauma memories that were more negative, contained higher sensory detail, and were more vivid. In contrast, depressive symptom severity predicted trauma memories that were less accessible and less coherent. These findings suggest that depressive and PTSD symptomatology affect traumatic memory differently and support a distinction between these two disorders.     

Predicting post‐traumatic growth and post‐traumatic stress in firefighters

Emergency service workers (e.g., firefighters, police, and paramedics) are exposed to elevated levels of potentially traumatising events through the course of their work. Such exposure can have lasting negative consequences (e.g., post‐traumatic stress disorder (PTSD)) and/or positive outcomes (e.g., post‐traumatic growth (PTG)). Research had implicated trauma, occupational and personal variables that account for variance in post‐trauma outcomes yet at this stage no research has investigated these factors and their relative influence on both PTSD and PTG in a single study. Based in Calhoun and Tedeschi's model of PTG and previous research, in this study regression models of PTG and PTSD symptoms among 218 firefighters were tested. Results indicated organisational factors predicted symptoms of PTSD, while there was partial support for the hypothesis that coping and social support would be predictors of PTG. Experiencing multiple sources of trauma, higher levels of organisational and operational stress, and utilising cognitive reappraisal coping were all significant predictors of PTSD symptoms. Increases in PTG were predicted by experiencing trauma from multiple sources and the use of self‐care coping. Results highlight the importance of organisational factors in the development of PTSD symptoms, and of individual factors for promoting PTG.     

Traumatic memories and pseudomemories in posttraumatic stress disorder

Intrusive imagery was investigated in survivors of motor vehicle accidents with (a) posttraumatic stress disorder (PTSD) and accurate recall of the trauma, (b) PTSD and amnesia of the trauma, (c) no PTSD, or (d) control participants who simulated PTSD. Imagery was precipitated by presentation of an audiotape of a motor vehicle accident. Whereas the traumatic imagery of participants who had accurate recall of their trauma was consistent with third party accounts of the trauma, the imagery of amnesic participants was inconsistent with these accounts. Participants were then interviewed about cognitive and emotional aspects of their responses. All participants with PTSD and simulators reported similar levels of imagery detail, involuntariness, re-experiencing, and emotional response, and reported higher levels than participants with no PTSD. Findings are discussed in terms of cognitive and contextual factors that can mediate accurate and inaccurate traumatic imagery. © 1998 John Wiley & Sons, Ltd.     

Protective role of coping flexibility in PTSD and depressive symptoms following trauma

The aim of the study was to examine whether coping flexibility would function as a protective factor for PTSD and depressive symptoms in trauma-exposed adults in Korea. A total of 510 adults with a lifetime history of traumatic events completed the Perceived Ability to Cope with Trauma (PACT), the Korea version of the Posttraumatic Stress Diagnostic Scale (PDS-K), and the Patient Health Questionnaire (PHQ-9). Hierarchical regression indicated that coping flexibility was associated with a reduced level of PTSD or depressive symptoms after controlling for comorbid symptoms, age, and elapsed time since the most distressing traumatic event. The interaction of traumatic events and coping flexibility was significant only on PTSD symptom severity but not on depressive symptom severity. Specifically, individuals with low coping flexibility reported higher levels of PTSD symptoms as the number of traumatic events increased. These findings supported the hypothesis that coping flexibility is a protective factor for PTSD and depression following trauma, and lack of coping flexibility may aggravate the risk for PTSD among people with multiple trauma.     

Mental health problems and post-migration stress among multi-traumatized refugees attending outpatient clinics upon resettlement to Norway

Refugees have often been exposed to multiple traumas making them prone to mental health problems later. The aim of this study is to describe the prevalence and symptom load of psychiatric disorders in refugees admitted to psychiatric outpatient clinics and to investigate the relationship between multiple exposure to traumatic events, the severity of traumatic symptoms and post-migration stressors. A clinical sample of 61 refugee outpatients from psychiatric clinics in Southern Norway was cross-sectionally examined using three structured clinical interviews (SCID-PTSD, SIDES and MINI) and self-report psychometric instruments (HSCL-25, IES-R). Post-traumatic Stress Disorder (PTSD) was diagnosed in 82% of the patients, while Disorders of Extreme Stress Not Otherwise Specified (DESNOS) was present in 16% of them. Comorbidity was considerable; 64% of the patients had both PTSD and major depression disorder (MDD) and 80% of those who had PTSD had three or more additional diagnoses. Multi-traumatized refugees in outpatient clinics have high prevalence of PTSD, DESNOS, comorbid depression and anxiety disorders. A more severe symptomatology was found in patients diagnosed with both PTSD and DESNOS, than in those diagnosed with only PTSD. Higher rates of unemployment, weak social network and weak social integration were also prevalent in these outpatients, and related to increased psychiatric comorbidity and severity of symptoms. Further research may clarify the existence of a cumulative relationship between pre-resettlement traumas and post-resettlement stressors in the mental health of refugees, which in turn may help to improve therapeutic interventions.     

Path analytic examination of a cognitive model of PTSD

Ehlers and Clark (2000) developed a cognitive model of posttraumatic stress disorder (PTSD) symptom maintenance which implicated the role of posttraumatic cognitions and aspects of the trauma memory in maintaining symptoms via an increased sense of current threat. The aim of the current study was to empirically test a variant of this model using path analysis. Participants in the current study were 514 undergraduates at a midwestern university who reported experiencing at least one traumatic event. Path analyses examined various models of the possible relationships between one’s posttraumatic cognitions and the centrality of the traumatic event to the sense of self (considered an aspect of memory integration) in predicting current level of PTSD symptoms. Results indicate that both event centrality and posttraumatic cognitions are unique and independent predictors of current symptom level. Overall, the results of this study support aspects of Ehlers and Clark’s cognitive model of PTSD; cognitive appraisals of the self and centrality of the event were highly related to levels of distress. However, the current study suggests that overly integrated trauma memories may lead to greater distress and not poorly integrated ones as suggested by Ehlers and Clark.     

Measurement differences from rating posttraumatic stress disorder symptoms in response to differentially distressing traumatic events

The authors explored differences in posttraumatic stress disorder (PTSD) symptoms as a result of rating symptoms from two separate, differentially distressing traumatic events. In an initial sample of 400 nonclinical participants, the authors inquired through a web survey about previous psychological trauma, instructing participants to nominate their most distressing and second most distressing traumatic events experienced. Using the PTSD Checklist, participants rated their PTSD symptoms separately from these worst and second worst events. Using the four-factor emotional numbing PTSD model in confirmatory factor analysis, results demonstrated evidence supporting separation of PTSD symptom rating sets from two differentially distressing traumas-specifically, the worst and second worst events. Measurement invariance tests revealed that factor loadings did not vary between the worst and second worst event PTSD ratings; item thresholds (indexing symptom severity) differed. Results generally support the recommended PTSD assessment protocol instructing participants to rate PTSD symptoms from a single, worst index event.     

Examining the role of emotional avoidance in the relationship between posttraumatic stress disorder symptom severity and worry

A growing body of literature suggests that worry is a cognitive activity functioning to avoid unpleasant internal experiences such as negative thoughts, emotions, and somatic responses. Given the highly aversive internal events associated with posttraumatic stress disorder (PTSD), individuals experiencing PTSD symptoms following exposure to a traumatic event may be particularly motivated to engage in avoidant regulation strategies such as worry. Surprisingly, however, few studies to date have examined the relationship between PTSD and worry as well as potential factors that might explain this association. Therefore, the goal of this study was to examine the association between PTSD symptom severity and worry and the extent to which emotional avoidance explains this relationship. To this end, 207 college students with a history of traumatic exposure (meeting Criterion A for a PTSD diagnosis) completed a series of questionnaires assessing history of exposure to potentially traumatic events, PTSD symptom severity, emotional avoidance tendencies, and worry. Results demonstrated that PTSD symptom severity was positively associated with worry and emotional avoidance. Further, emotional avoidance was found to fully account for this relationship, providing support for the proposed emotionally avoidant function of worry. The implications of these findings for future research and the treatment of worry among individuals with a history of traumatic exposure are discussed.     

Posttraumatic stress disorder in the emergency room: exploration of a cognitive model

Ehlers and Clark (Behav. Res. Ther., 38 (2000) 319) recently proposed a cognitive model of posttraumatic stress disorder (PTSD). In this study, we examined two facets of this model, appraisal and peritraumatic dissociation, in the context of a hospital emergency room. Fifty-one emergency room personnel completed questionnaires measuring posttraumatic stress symptoms, interpretations of traumatic events experienced while working in the emergency room and subsequent intrusive recollections, and peritraumatic dissociation. Twelve percent of participants met formal diagnostic criteria for PTSD, and 20% met PTSD symptom criteria. As predicted, both negative appraisals of the trauma and of intrusive recollections were associated with increased PTSD severity. Although peritraumatic dissociation did not correlate with overall PTSD symptom severity, it was associated with the reexperiencing symptom cluster. Discussion focuses on the factors associated with PTSD in emergency room professionals and implications for intervention.     

Motor vehicle accident trauma exposure: Personality profiles associated with posttraumatic diagnoses

Abstract

Personality profiles associated with diagnostically distinct posttraumatic responses were examined. Profiles were compared between three groups defined on the basis of posttraumatic diagnosis following motor vehicle accident (MVA) trauma exposure. The diagnostic groups were: Posttraumatic Stress Disorder (PTSD), Acute Stress Disorder (ASD) without progression to PTSD, and subclinical responses. Participants were male and female community volunteers aged 18 to 77 (N = 83) who had all been exposed to an MVA meeting the DSM-IV diagnostic criteria for a traumatic event. The Personality Assessment Inventory (Morey, 1991) was used to assess psychological variables in the framework of posttraumatic diagnostic groups. The PTSD group scored significantly higher than the ASD and subclinical groups on scales assessing somatic complaints, anxiety, anxiety related disorders, depression, non-psychotic symptoms of schizophrenia, and negative relationships. The profile of the ASD group was characterized by self report of greater interpersonal warmth and a trend for greater egocentricity than the PTSD group. There were no significant differences in the personality profiles of the ASD and subclinical groups. The role of personality factors in posttraumatic adjustment is discussed in the context of previous literature.     

Traumatic Experiences and PTSD Among Adolescent Congolese Refugees in Uganda: A Preliminary Study

The study examined experienced traumatic events and the related Post-Traumatic Stress Disorder (PTSD) amongst a sample of 89 adolescent Congolese refugees (56 females and 33 males) at a refugee camp in Uganda. Data was collected using a questionnaire, and analyzed for trauma moderation by demographics and mediation by PTSD symptom scores. Findings indicate a prevalence of PTSD of 49.4% overall, with 75% of the female refugees meeting the PTSD criteria. The refugees with PTSD had high intrusive, avoidance and arousal scores, in addition to moderate to severe PTSD symptom severity scores. Trauma load was a significant predictor of PTSD among adolescent refugees. Our findings point to the high prevalence of PTSD resulting from an increased trauma load and being a female.     

A Preliminary Examination of Thought Suppression,Emotion Regulation,and Coping in a Trauma-Exposed Sample

Attempts to modulate negative emotional and cognitive symptoms of posttraumatic stress disorder (PTSD) may be related to psychopathology. Trauma-exposed undergraduates, 31 reporting severe PTSD symptoms (PTSD group) and 34 without PTSD symptoms (non-PTSD group), completed measures of PTSD, depression, anxiety, thought control, emotion regulation, and coping. The PTSD group had greater psychopathology and overall modulation strategy use than the non-PTSD group. Thought suppression, emotion suppression, and avoidant coping strategies were positively related to psychopathology, whereas emotion reappraisal and approach coping strategies were either not related or weakly negatively related. Hierarchical multiple regressions with psychopathologic variables as criteria and modulation strategies as predictors indicated significant models in all cases. Generally, thought suppression was the only significant independent predictor of psychopathology.     

Mental flexibility as resiliency factor among children exposed to political violence

The research focused on mental flexibility versus rigidity in explaining psychological adjustment in the violent conditions of Intifada, and in more peaceful times 3 years later, among 86 Palestinian children. A picture test based on Brunswik (1949) was applied to measure flexible‐rigid cognitive style, and neuroticism, self‐esteem, emotional disorders, and PTSD were used as outcome variables. Results revealed a moderating role of mental flexibility by showing that children were protected from negative long‐term consequences of traumatic events if their perception indicated mental flexibility. However, in the midst of violence mental flexibility was not associated with good psychological adjustment. Mental flexibility was, in turn, determined by environmental and cognitive factors: The more intelligent and the less exposed to traumatic events children were, the higher mental flexibility they showed.     

Relationships among Proactive Coping,Posttrauma Gratitude,and Psychopathology in a Traumatized College Sample

Scant previous research has examined associations of proactive coping and psychopathology, although two preliminary findings suggest that proactive coping might be negatively associated with posttraumatic stress disorder (PTSD) and general depression symptom level. This study examined associations of proactive coping with PTSD and anhedonic depression in a sample of 169 traumatized undergraduates. As expected, women tended to report more severe PTSD symptoms and less life threat than men. No other gender differences were found. Most important, proactive coping and posttrauma state gratitude were independently negatively associated with PTSD symptom level, after controlling for trauma history and female gender. Further, proactive coping was independently negatively associated with anhedonic depression, beyond the effect of traumatic life threat. The implications of the findings for models of posttrauma psychopathology development are discussed.     

Sequential Temporal Dependencies in Associations Between Symptoms of Depression and Posttraumatic Stress Disorder: An Application of Bivariate Latent Difference Score Structural Equation Modeling

Depression and posttraumatic stress disorder (PTSD) are highly comorbid conditions that may arise following exposure to psychological trauma. This study examined their temporal sequencing and mutual influence using bivariate latent difference score structural equation modeling. Longitudinal data from 182 emergency room patients revealed level of depression symptom severity to be positively associated with changes in PTSD intrusion, avoidance, and hyperarousal over 3 time intervals, beginning shortly after the traumatic event. Higher scores on depression anticipated increases (or worsening) in PTSD symptom severity. The pattern of influence from PTSD symptom severity to change in depression symptom severity simply followed the general trend toward health and well-being. Results are discussed in terms of the dynamic interplay and associated mechanisms of posttrauma depression and PTSD symptom severity.     

Memory in posttraumatic stress disorder: properties of voluntary and involuntary, traumatic and nontraumatic autobiographical memories in people with and without posttraumatic stress disorder symptoms

One hundred fifteen undergraduates rated 15 word-cued memories and their 3 most negatively stressful, 3 most positive, and 7 most important events and completed tests of personality and depression. Eighty-nine also recorded involuntary memories online for 1 week. In the first 3-way comparisons needed to test existing theories, comparisons were made of memories of stressful events versus control events and involuntary versus voluntary memories in people high versus low in posttraumatic stress disorder (PTSD) symptom severity. For all participants, stressful memories had more emotional intensity, more frequent voluntary and involuntary retrieval, but not more fragmentation. For all memories, participants with greater PTSD symptom severity showed the same differences. Involuntary memories had more emotional intensity and less centrality to the life story than voluntary memories. Meeting the diagnostic criteria for traumatic events had no effect, but the emotional responses to events did. In 533 undergraduates, correlations among measures were replicated and the Negative Intensity factor of the Affect Intensity Measure correlated with PTSD symptom severity. No special trauma mechanisms were needed to account for the results, which are summarized by the autobiographical memory theory of PTSD.
