Characteristics of emergency services personnel related to peritraumatic dissociation during critical incident exposure

The association between reality-based beliefs and indirectly experienced traumatization

The purpose of the study was to examine the association between belief types and the magnitude of indirect traumatization. Specific types of beliefs were defined in terms of the cognitive orientation theory, which is a cognitive-motivational approach to the understanding, predicting, and changing of behaviors. Belief types that were analyzed included beliefs about self, general beliefs, beliefs about norms, and goal beliefs as they relate to personal growth. Study participants included 38 rescuers (body handlers), 37 nurses, and 31 rehabilitation workers who treated injured civilians that had been exposed to politically motivated violence. The Cognitive Orientation for Posttraumatic Growth Scale was used to assess beliefs about personal growth. The Revised Posttraumatic Stress Disorder Inventory was administered to evaluate indirect traumatization. The results indicate that three of the four belief types related to personal growth were associated with the level of indirect traumatization. Optimistic and positive beliefs about self and general beliefs were associated with a lower level of indirect traumatization symptomatology, suggesting that these types of beliefs may counteract indirect traumatization. On the other hand, stronger goal beliefs were associated with greater indirect traumatization. The negative association between positive goal beliefs and indirect trauma may be related to the gap the individual perceives between the hoped-for ideals and the trauma-stricken reality. These results indicate the importance of cognitive beliefs and their possible role in determining the response to indirect traumatization.

Validation of the Peritraumatic Dissociative Experiences Questionnaire and Peritraumatic Distress Inventory in school-aged victims of road traffic accidents

BACKGROUND

Although the reliable and valid Peritraumatic Distress Inventory (PDI-C) and Peritraumatic Dissociative Experiences Questionnaire (PDEQ) are useful for identifying adults at risk of developing acute and chronic posttraumatic stress disorder (PTSD), they have not been validated in school-aged children and their predictive values remain unknown in this population. This study aims to assess the psychometric properties of the children versions of these two measures (PDI-C and PDEQ-C) in a sample of French-speaking school-children.

METHODS

One-hundred and thirty-three consecutive victims of road traffic accidents, aged 8-15 years, were recruited into this longitudinal study via the emergency room. The peritraumatic reactions were assessed at baseline and PTSD symptoms were assessed 1 month later.

RESULTS

Cronbach's alpha coefficients were 0.8 and 0.77 for the PDI-C and PDEQ-C, respectively. The 1-month test-retest correlation coefficient (n=33) was 0.77 for both measures. The PDI-C demonstrated a two-factor structure while the PDEQ-C displayed a one-factor structure. As with adults, the two measures were intercorrelated (r=0.52) and correlated with subsequent PTSD symptoms and diagnosis (r=0.21-0.56; P<0.05).

CONCLUSIONS

The children versions of the PDI and PDEQ are reliable and valid in children.

Cognitive processes in dissociation: comment on Giesbrecht et al. (2008)

In their recent review "Cognitive Processes in Dissociation: An Analysis of Core Theoretical Assumptions," published in Psychological Bulletin, Giesbrecht, Lynn, Lilienfeld, and Merckelbach have challenged the widely accepted trauma theory of dissociation, which holds that dissociative symptoms are caused by traumatic stress. In doing so, the authors have outlined a series of links between various constructs--such as fantasy proneness, cognitive failures, absorption, suggestibility, altered information-processing, dissociation, and amnesia--claiming that these linkages lead to the false conclusion that trauma causes dissociation. A review of the literature, however, shows that these are not necessarily related constructs. Careful examination of their arguments reveals no basis for the conclusion that there is no association between trauma and dissociation. The current comment offers a critical review and rebuttal of Giesbrecht et al.'s argument that there is no relationship between trauma and dissociation.

A prospective study of trait anger and PTSD symptoms in police

It is unknown whether anger is a risk factor for the development of posttraumatic stress disorder ( PTSD) symptoms, arises as a consequence of PTSD, or both. Two hypotheses were tested in 180 police recruits: Greater trait anger during training will predict greater PTSD symptoms at one year; greater PTSD symptoms at one year will predict greater state anger at one year. Both hypotheses were confirmed, suggesting that trait anger is a risk factor for PTSD symptoms, but that PTSD symptoms are also associated with an increase of state anger. Increased anger is important not only because of the impact it has on individual distress and physical health, but also because of its potential public health impact.

True and false recall and dissociation among maltreated children: the role of self-schema

The current investigation addresses the manner through which trauma affects basic memory and self-system processes. True and false recall for self-referent stimuli were assessed in conjunction with dissociative symptomatology among abused (N=76), neglected (N=92), and nonmaltreated (N=116) school-aged children. Abused, neglected, and nonmaltreated children did not differ in the level of processing self-schema effect or in the occurrence and frequency of false recall. Rather, differences in the affective valence of false recall emerged as a function of maltreatment subtype and age. Regarding dissociation, the abused children displayed higher levels of dissociative symptomatology than did the nonmaltreated children. Although abused, neglected, and nonmaltreated children did not exhibit differences in the valence of their self-schemas, positive and negative self-schemas were related to self-integration differently among the subgroups of maltreatment. Negative self-schemas were associated with increased dissociation among the abused children, whereas positive self-schemas were related to increased dissociation for the neglected children. Thus, positive self-schemas displayed by the younger neglected children were related to higher dissociation, suggestive of defensive self-processing. Implications for clinical intervention are underscored.

Child sexual abuse, coping strategies and lifetime posttraumatic stress disorder among female inmates

The purpose of the study was to assess the relationship between child sexual abuse (CSA) and posttraumatic stress disorder (PTSD) in female inmates in China. A total of 471 participants were assessed for CSA, personality traits, coping strategies, and frequency of lifetime PTSD. Results demonstrated that CSA and negative coping were predictive factors for lifetime PTSD among female inmates after personality traits were controlled. The findings suggest that CSA is one potential factor contributing to lifetime PTSD among female inmates. The importance of screening for CSA among female inmates was highly emphasized. Early intervention and prevention programmes based on coping skills may be useful to forestall the development of chronic PTSD in female inmates.

Modification effects of coping on post-traumatic morbidity among earthquake rescuers

This study aims to investigate the modification effects of coping strategies on the relationships between rescue effort and psychiatric morbidity (i.e. general psychiatric morbidity and post-traumatic morbidity) in earthquake rescue workers. Firefighters (n=193) who were involved in the rescue effort after the Taiwan Chi-Chi earthquake were invited to complete a questionnaire which contained questions on demographics, exposure to rescue work, general psychiatric morbidity, post-traumatic morbidity, and coping strategies. Multivariate regression models with interaction terms were carried out to investigate the modification effect of coping strategies on the relationships between rescue effort and psychiatric morbidities. Older age and longer job experiences (>3 years) were associated with both general psychiatric and post-traumatic morbidities. Coping strategies such as confrontive coping, distancing, seeking social support, accepting responsibility, escape-avoidance, planful problem solving, and positive appraisal significantly modified the effect of exposure to dead bodies on general psychiatric morbidity. Furthermore, confrontive coping, distancing, and planned problem solving significantly modified the effect of exposure to direct rescue involvement on general psychiatric morbidity. However, coping strategies were not observed to buffer the effect of rescue involvement or contact with dead bodies on post-traumatic morbidity. More frequent use of coping strategies could reduce the effect that exposure to rescue efforts has on the incidence of general psychiatric morbidity in rescue workers. However, coping strategies do not seem to reduce the influence of such exposure on trauma-related morbidities. This suggests that coping strategies can be used to prevent general psychiatric morbidity but not trauma-related morbidities.

Coping with posttraumatic stress disorder and comorbidity after myocardial infarction

OBJECTIVE

Literature on the relationship between coping strategies, posttraumatic stress after myocardial infarction (post-MI PTSD), and comorbidity is limited. This study aimed to fill this gap in literature by investigating this relationship.

METHOD

One hundred twenty patients with MI were recruited from 2 general practices and interviewed using the Posttraumatic Stress Diagnostic Scale, the General Health Questionnaire, and the COPE Scale.

RESULTS

Thirty-one percent had PTSD. Patients used acceptance-focused coping in that most of them accepted that the MI had happened and that it could not be changed. At the same time, some patients used avoidance-focused coping in that they disengaged themselves mentally and behaviorally from the traumatic effects of MI. When the variables of age, bypass surgery, mental health problems before MI, and angioplasty were held constant, the results showed that patients who used maladaptive coping strategies of emotion-focused and avoidance-focused copings tended to report more comorbid symptoms. Patients who underwent medical procedures or interventions such as bypass surgery and angioplasty tended to report more PTSD symptoms.

CONCLUSIONS

The way in which MI patients' coping strategies relate to health outcomes has been shown to be symptom-specific. Using maladaptive coping strategies does not necessarily have a significant impact on PTSD symptoms. On the other hand, medical procedures or interventions for treating MI can play a major role in maintaining PTSD symptoms for patients with MI.

Propranolol and the prevention of post-traumatic stress disorder: is it wrong to erase the "sting" of bad memories?

The National Institute of Mental Health (Bethesda, MD) reports that approximately 5.2 million Americans experience post-traumatic stress disorder (PTSD) each year. PTSD can be severely debilitating and diminish quality of life for patients and those who care for them. Studies have indicated that propranolol, a beta-blocker, reduces consolidation of emotional memory. When administered immediately after a psychic trauma, it is efficacious as a prophylactic for PTSD. Use of such memory-altering drugs raises important ethical concerns, including some futuristic dystopias put forth by the President's Council on Bioethics. We think that adequate informed consent should facilitate ethical research using propranolol and, if it proves efficacious, routine treatment. Clinical evidence from studies should certainly continue to evaluate realistic concerns about possible ill effects of diminishing memory. If memory-attenuating drugs prove effective, we believe that the most immediate social concern is the over-medicalization of bad memories, and its subsequent exploitation by the pharmaceutical industry.

Dissociation and pain perception: an experimental investigation

Dissociative symptoms and abnormalities in pain perception have been associated with a range of disorders. The authors tested whether experimentally induced increases in state dissociation would cause an analgesic response. Participants (N = 120) were randomized to a dissociation induction condition via audiophotic stimulation or a credible control condition and were compared on pre- and postchanges in subjective pain and immersion time in response to a standard cold pressor test. Unexpectedly, the dissociation induction led to small, but significant increases in subjective pain and did not lead to greater immersion time. An exploratory analysis revealed that increases in absorption and derealization significantly predicted increased subjective pain and increased immersion time, respectively.

Resilience: research evidence and conceptual considerations for posttraumatic stress disorder

The growing recognition and occurrence of traumatic exposure in the general population has given increased salience to the need to understand the concept of resilience. More than just the "flip side" of a risk factor, the notion of resilience encompasses psychological and biological characteristics, intrinsic to an individual, that might be modifiable and that confer protection against the development of psychopathology in the face of stress. In this review, we provide some perspective on the concept of "resilience" by examining early use of the term in research on "children at risk" and discuss the relationship between risk and resilience factors. We then review psychological and biological factors that may confer resilience to the development of posttraumatic stress disorder (PTSD) following trauma, examine how resilience has been assessed and measured, and discuss issues to be addressed in furthering our understanding of this critical concept going forward.

Peritraumatic fear, helplessness and horror and peritraumatic dissociation: Do physical and cognitive symptoms of panic mediate the relationship between the two?

The goal of this study was to examine whether panic mediates the relationship between fear, helplessness, and horror (PTSD criterion A2) and dissociation at the time of trauma. The study sample included 709 police officers and 317 peer-nominated civilians who had been exposed to a variety of critical incidents. Participants filled out measures of critical incident exposure, PTSD criterion A2, panic, and dissociation. Results indicate that together, physical and cognitive symptoms of panic completely mediate the relationship between criterion A2 and dissociation in civilians, and partially mediate that relationship in police. These results provide support for the idea that panic mediates the relationship between fear, helplessness, and horror (criterion A2) and dissociation at the time of trauma. The results also raise the possibility, however, that the mediational role of panic may be further moderated by additional variables.

Examining the correlates of engagement and disengagement coping among help-seeking battered women

This study examined several potential correlates of engagement and disengagement coping, including abuse-related factors, socioeconomic and social coping resources, and childhood trauma variables among a sample of battered women (N = 388). Relationship abuse frequency, particularly psychological aggression, and peritraumatic dissociation were the strongest positive predictors of the use of disengagement coping. Social coping resources, including tangible support and appraisals of social support and belonging, were associated with higher engagement coping and lower disengagement coping. A positive association was also found between interparental domestic violence and disengagement coping, and negative associations were found between both childhood physical and sexual abuse and engagement coping. Results suggest that coping strategies used by battered women are multidetermined and deserve further exploration.

Recovered memory and the Daubert criteria: recovered memory as professionally tested, peer reviewed, and accepted in the relevant scientific community

Research during the past two decades has firmly established the reliability of the phenomenon of recovered memory. This review first highlights the strongest evidence for the phenomenon itself and discusses the survey, experimental, and biological evidence for the varying mechanisms that may underlie the phenomenon. Routes to traumatic amnesia from dissociative detachment (loss of emotional content leading to loss of factual content) and from dissociative compartmentalization (failure in integration) are discussed. Next, an argument is made that false memory is a largely orthogonal concept to recovered memory; the possibility of one phenomena is largely irrelevant to the potential for the other. Furthermore, some aspects of the false memory research offer supportive data for the recovered memory researcher. Finally, the issue of error rates in making the Daubert case is explored. It is concluded that the weight of the evidence should allow the recovered memory victim to come before the court.

The impact of personal threat on police officers' responses to critical incident stressors

The relationship of type of critical incident (CI) stressor with peritraumatic responses and posttraumatic stress disorder symptoms was examined in police. Officers (N = 662) provided narratives of their most distressing CI experienced during police service and completed measures of related peritraumatic responses and posttraumatic stress disorder symptoms. Narratives were reliably rated (kappa = .80-1.0) on seven categories emerging from a series of factor analyses of a measure of critical incident stressors. Additional analysis revealed that the classification of primary narrative features required only five categories (personal life threat, duty-related violence, encountering physical or sexual assault victims, exposure to civilian death, other). When analyzed by further collapsing these five categories into high versus low personal threat, officers whose narratives contained high personal threat reported more peritraumatic dissociation, peritraumatic emotional distress, and current hyperarousal symptoms. Results suggest that greater personal threat during a CI may place an officer at greater risk for subsequent distress.

Health status in the ambulance services: a systematic review

Background

Researchers have become increasingly aware that ambulance personnel may be at risk of developing work-related health problems. This article systematically explores the literature on health problems and work-related and individual health predictors in the ambulance services.

Methods

We identified the relevant empirical literature by searching several electronic databases including Medline, EMBASE, PsychINFO, CINAHL, and ISI Web of Science. Other relevant sources were identified through reference lists and other relevant studies known by the research group.

Results

Forty-nine studies are included in this review. Our analysis shows that ambulance workers have a higher standardized mortality rate, higher level of fatal accidents, higher level of accident injuries and a higher standardized early retirement on medical grounds than the general working population and workers in other health occupations. Ambulance workers also seem to have more musculoskeletal problems than the general population. These conclusions are preliminary at present because each is based on a single study. More studies have addressed mental health problems. The prevalence of post-traumatic stress symptom caseness was > 20% in five of seven studies, and similarly high prevalence rates were reported for anxiety and general psychopathology in four of five studies. However, it is unclear whether ambulance personnel suffer from more mental health problems than the general working population.

Conclusion

Several indicators suggest that workers in the ambulance services experience more health problems than the general working population and workers in other health occupations. Several methodological challenges, such as small sample sizes, non-representative samples, and lack of comparisons with normative data limit the interpretation of many studies. More coordinated research and replication are needed to compare data across studies. We discuss some strategies for future research.

Predictors of Posttraumatic Stress in Police and Other First Responders

We provide an overview of previous research conducted by our group on risk and resilience factors for PTSD symptoms in police and other first responders. Based on our work, the findings of other investigators on individual differences in risk for PTSD, and drawing on preclinical studies fear conditioning and extinction, we propose a conceptual model for the development of PTSD symptoms emphasizing the role of vulnerability and resilience to peritraumatic panic reactions. We tested this conceptual model in a cross-sectional sample of police officers (n = 715). Utilizing an hierarchical linear regression model we were able to explain 39.7% of the variance in PTSD symptoms. Five variables remained significant in the final model; greater peritraumatic distress (beta = 0.240, P < .001), greater peritraumatic dissociation (beta = 0.174, P < .001), greater problem-solving coping (beta = 0.103, P < .01), greater routine work environment stress (beta = 0.182, P < .001), and lower levels of social support (beta = -0.246, P < .001). These results were largely consistent with the proposed conceptual model. Next steps in this line of research will be to test this model prospectively in a sample of 400 police academy recruits assessed during training and currently being followed for the first 2 years of police service.

Current affairs and the public psyche: American anxiety in the post 9/11 world

BACKGROUND

The most recent wave of interviews in a longitudinal study spanned the terrorist attacks of September 11, 2001. This unintended "natural experiment" allows examination of effects of traumatic events in ways impossible in studies conducted solely after the event and in populations not previously studied.

METHODS

Participants were 610 members of the randomly selected Children in the Community cohort studied longitudinally for over 25 years and between ages 27 and 38 at the time of the current in-home interviews. Symptoms of generalized anxiety, post-traumatic stress disorder, panic disorder, agoraphobia, dissociation, and depression were assessed with an adaptation of the Structured Clinical Interview for Diagnosis. Changes in self-reported symptoms from an assessment 10 years earlier were related to the date of interview between 7/2001 and 12/2003 by polynomial regression methods, including demographic and design controls. Diagnoses based on clinical follow-up were also examined.

RESULTS

In contrast to other data on this cohort where timing effects were absent, levels of symptoms were related to time of interview. The months following 9/11/2001 and the two anniversary periods in 2002 and 2003 showed significant elevation in anxiety symptoms (t = 2.50, df = 608, P = 0.013) with some evidence of elevated anxiety disorder as well (Fisher's exact test P = 0.096). Similar patterns were seen for specific anxiety and depressive symptom groups. Effects of religious participation, patriotism, having offspring, and media exposure on anxiety symptoms tended to differ by season, but the effect of community involvement did not. Proximity to New York City was not significantly related to symptoms.

CONCLUSIONS

Study findings suggest that young Americans showed symptomatic and, possibly, diagnostic anxiety reactions to the events of 9/11 that persisted in response to heightened awareness of ongoing threat during anniversary periods.

The health of volunteer firefighters three years after a technological disaster

On May 13, 2000, a firework depot exploded in a residential area of the city of Enschede, The Netherlands. Many disaster workers responded, including volunteer firefighters, a group that has received little attention in disaster research. This study examined the presence of health problems in volunteer firefighters who were involved in disaster work, three years after the disaster. Furthermore, it was investigated whether demographic characteristics and disaster exposure predicted health problems. The study population consisted of 246 volunteer firefighters who were deployed in disaster work and 71 non-deployed controls. These firefighters completed a questionnaire which inquired about their perceived health and health change, physical symptoms, post-traumatic stress, mental health problems, and health care utilization. Three years after the disaster, no health differences emerged between deployed and non-deployed firefighters. Good health and health improvement over the previous year were reported. Respondents who encountered more distressing experiences during disaster work or carried out more direct disaster-related recovery tasks reported more mental health problems and health care utilization. However, the most reliable predictors of health problems were distressing experiences unrelated to the disaster in personal life or during work. Three years after the disaster, the health of volunteer firefighters involved in the disaster work was not much impaired, possibly because aftercare was available and utilized. Nevertheless, disaster exposure was associated with elevated post-traumatic stress symptoms and mental health care utilization. Health care workers should direct specific attention to the treatment and prevention of post-traumatic stress symptoms in cases of major accidents or disasters.

Social workers confront terrorist victims: The interventions and the difficulties

The article deals with unremitting stress experienced by social workers dealing with terror victims. The article will describe the activity of social workers responsible for setting up a hospital information center. It will describe how they assist families searching for their loved ones and the process of identifying victims. The process in which the uncertainty is treated, the anxiety is contained, bad news are conveyed and concrete solutions are provided, will be elaborated on. Special emphasis will be placed on the multifaceted complimentary relationship between team members and between the provision of support, role exchange and the opportunity to share difficult experiences. The team is expert in identifying both personal and collective signs of distress. This is of particular significance and importance in connection with compassion fatigue, survival guilt, anxiety, depression and on- going burnout, regarding themselves and their colleagues. The article will propose organizational and clinical solutions, which could also be of service to other frameworks within the health system.

A preliminary study of peritraumatic dissociation, social support, and coping in relation to posttraumatic stress symptoms for a parent's cancer

This study examined predictors of posttraumatic stress disorder (PTSD) symptoms in adults who, as children, had a parent diagnosed with cancer. Possible predictors of adulthood PTSD examined were peritraumatic dissociation, satisfaction with social support, coping through denial, behavioral disengagement and self-distraction, and whether or not the parent died. Thirty research participants (20 women and 10 men, ages 18-38) were recruited who were 8-17-years old at the time of a parent's cancer diagnosis. Each participant completed measures of their current PTSD symptoms in response to their parent's cancer, peritraumatic dissociative experiences, demographic characteristics, and satisfaction with social support and use of coping strategies at the time of their parent's cancer diagnosis. Seventeen percent met screening criteria for likely PTSD. As hypothesized, PTSD symptoms were strongly and positively correlated with peritraumatic dissociation. Furthermore, PTSD symptoms were greater among females and were related to greater use of denial and behavioral disengagement and to less satisfaction with social support. These results suggest that health care providers need to recognize symptoms of peritraumatic dissociation in the children of parents who are diagnosed with cancer so that steps can be taken to minimize the children's development of PTSD that may extend into their adult lives.

The psychobiology of PTSD: coping with trauma

Posttraumatic stress disorder (PTSD) is one of the few psychiatric conditions where a specific psychosocial stressor is explicitly tied to etiology. Although a majority of people experience a traumatic event in their life, most of them will not develop PTSD or other mental health problems such as depressive or anxiety disorders. Emotional and neurobiological responses to psychosocial stressors show striking individual variation. In this paper cognitive appraisal and coping factors are explored as potential sources of individual differences in the neuroendocrinological stress response, and subsequently in mental health outcome. Continued study of the psychobiology of trauma and PTSD will enhance our understanding of adaptation to psychosocial stressors and support efforts to treat associated psychological and biological sequelae.

Civilian PTSD scales: relationships with trait characteristics and everyday distress

Strong associations between civilian posttraumatic stress disorder (PTSD) scales and measures of general psychological distress suggest that the scales are nonspecific to PTSD. Three common PTSD scales were administered to 122 undergraduates who had experienced an emotionally salient, nontraumatic event: a college examination. Results indicated that normal levels of anxiety associated with the examination were positively correlated with scores on the Impact of Event Scale-Revised, Revised Civilian Mississippi Scale, and PTSD Checklist-Civilian Version. Multiple regression analyses indicated that substantial variance in the PTSD scales was accounted for by trait characteristics such as negative and positive affectivity and affect intensity (R2 .29 to .53). Negative affectivity correlated as highly with PTSD measures (r = .46 to .71) as those measures correlated with each other (r = .48 to .65). A high proportion of participants exceeded clinical cutoffs on these measures. The findings suggest that these PTSD scales may be overly sensitive to nontraumatic stressors such as everyday distress and trait characteristics.

Peritraumatic dissociation and experiential avoidance as predictors of posttraumatic stress symptomatology

This study examined whether peritraumatic dissociation serves as a proxy risk factor for experiential avoidance in its relationship with posttraumatic stress disorder (PTSD) symptomatology. One hundred eighty-five trauma survivors completed measures that assessed for peritraumatic dissociation, experiential avoidance, and PTSD symptom severity. The results indicated that peritraumatic dissociation and experiential avoidance were significantly related to PTSD symptomatology at baseline. However, after initial levels of PTSD symptomatology were taken into account, only experiential avoidance was related to PTSD symptoms both 4- and 8-weeks later. These results indicate that peritraumatic dissociation is not a proxy risk factor for experiential avoidance and contributes to the growing body of literature indicating that experiential avoidance is an important factor related to the psychological symptoms experienced by trauma survivors.

Risk and resilience in canine search and rescue handlers after 9/11

Research has suggested that rescue workers are at increased risk for psychological distress. To determine whether 9/11 deployment was a significant risk factor for canine search and rescue handlers, 82 deployed handlers were compared to 32 nondeployed handlers on measures of posttraumatic stress disorder (PTSD), depression, anxiety, acute stress, and clinical diagnoses. Deployed handlers reported more PTSD and general psychological distress 6 months after 9/11. Among deployed handlers, prior diagnoses and peritraumatic reactions were associated with psychological distress whereas social support and training were protective. Results suggest that more extensive screening and prophylactic interventions for individuals with a history of mental illness could be beneficial. Future research should examine identified risk/resilience factors prospectively, and training and intervention should be designed accordingly.

Adaptação transcultural para o português do instrumento Peritraumatic Dissociative Experiences Questionnaire, Versão Auto-Aplicativa

INTRODUÇÃO: Este artigo apresenta a adaptação transcultural para o português do instrumento Peritraumatic Dissociative Experiences Questionnaire, Self-Report Version (PDEQ-SRV), para rastrear e quantificar os fenômenos dissociativos peritraumáticos. MÉTODOS: Fizeram-se duas traduções e suas respectivas retrotraduções, avaliação da equivalência semântica, elaboração da versão-síntese, pré-teste na população-alvo e realização da versão final. RESULTADOS: Observou-se um grau elevado de equivalência semântica entre o instrumento original e os dois pares de traduções/retrotraduções da perspectiva dos significados referencial e geral. O pré-teste na população-alvo conduziu a poucas modificações, que confirmaram a realização dos critérios de equivalência semântica. DISCUSSÃO: Este trabalho disponibiliza a primeira adaptação para o contexto brasileiro de um instrumento específico para a detecção e a quantificação de sintomas dissociativos peritraumáticos.

Why are hispanics at greater risk for PTSD?

Several studies have found that Hispanic Americans have higher rates of posttraumatic stress disorder (PTSD) than non-Hispanic Caucasian and Black Americans. The authors identified predictors of PTSD symptom severity that distinguished Hispanic police officers (n=189) from their non-Hispanic Caucasian (n=317) and Black (n=162) counterparts and modeled them to explain the elevated Hispanic risk for PTSD. The authors found that greater peritraumatic dissociation, greater wishful thinking and self-blame coping, lower social support, and greater perceived racism were important variables in explaining the elevated PTSD symptoms among Hispanics. Results are discussed in the context of Hispanic culture and may be important for prevention of mental illness in the fastest growing ethnic group in the United States.

The Progression of Holism Into Postgraduate Curricula in Critical Care Nursing

Critical care education is an important part of the professional development of a competent critical care nurse. Interdependence between physiological and psychosocial theories and concepts is a key consideration in the development of critical care educational programs. This multidisciplinary educational framework fosters a deeper understanding of factors contributing to ill health. Establishing a strategic framework where research, education, clinical excellence, and quality assurance are interlinked is central to enhancing the efficacy of patient care outcomes.

Dissociation related to subjective memory fragmentation and intrusions but not to objective memory disturbances

The present study was a replication of Kindt and Van den Hout (Behaviour Research and Therapy 41 (2003) 167) with several methodological adaptations. Two experiments were designed to test whether state dissociation is related to objective memory disturbances, or whether dissociation is confined to the realm of subjective experience. High trait dissociative participants (N(exp.1)=25; N(exp.2)=25) and low trait dissociative participants (N(exp.1)=25; N(exp.2)=25) were selected from normal samples (N(exp.1)=372; N(exp.2)=341) on basis of scores on the Dissociative Experience Scale (DES). Participants watched an extremely aversive film, after which state dissociation was measured by the Peri-traumatic Dissociative Experience Questionnaire (PDEQ). Memory disturbances were assessed 4h later (Exp. 1) or 1 week later (Exp. 2). Objective memory disturbances were assessed by a sequential memory task, items tapping perceptual representations (Exp. 1), or an open question with respect to the remembrance of the film (Exp. 2). Subjective memory disturbances were measured by means of visual analogue scales assessing fragmentation and intrusions. The two experiments provided a fairly exact replication of an earlier experiment (Behaviour Research and Therapy 41 (2003) 167-178), indicating a relation between dissociation and memory disturbances that appeared to be confined to the subjective experience of memory.

A snapshot of terror: acute posttraumatic responses to the September 11 attack

This paper reports on acute posttraumatic reactions and forms of coping to the September 11 attack. We conducted a survey within three weeks of the attack on a nationwide, representative sample of individuals 13 years or older (N = 3,134). Measures included the Stanford Acute Stress Reaction Questionnaire (SASRQ), the brief version of the COPE, and questions about demographics and attitudes toward the attackers. Results show that residents of New York City--women, young adults (but not teens), and people recently immigrated into the country--experienced more distress about the attack. There was a positive linear association between hours of watching TV news related to the attack and distress, and a small positive association between hostility toward the perpetrators, TV watching, and distress. Income, religion, education, and ethnicity did not have an effect on distress. Maladaptive coping strategies and TV watching explained considerably more variance than did demographics. Reactions to acute trauma seem to depend on the lack of appropriate coping strategies. The curvilinear relationship between age and posttraumatic distress suggests caution when interpreting previous findings about age and posttraumatic reactions. The association between media exposure, coping styles, and acute distress among teens extends previous findings and deserves further investigation.

Comparisons between high and low peritraumatic dissociators in cardiovascular and emotional activity while remembering trauma

Peritraumatic dissociation (PD) is one of the best predictors of posttraumatic stress disorder (PTSD). In this pilot study, we examined cardiovascular psychophysiology and negative emotions in 19 adults who, retrospectively, reported experiencing high or low levels of PD during the worst trauma of their lives. In a contiguous series of ten-minute phases, they rested, thought about, talked about, and recovered from talking about their index trauma. We hypothesized that greater PD would be associated with more negative emotion, lower cardiovascular activity, and greater discordance between negative emotions and cardiovascular activity. Our main findings were that PD was associated with lower blood pressure prior to talking about the trauma, greater negative emotion while talking about the trauma, and greater emotional and cardiovascular discordance throughout the experiment. These findings add to the very limited empirical data on physiological concomitants of peritraumatic dissociation and may aid in developing preventive interventions for PTSD.

Peritraumatic dissociation and emotions as predictors of PTSD symptoms following childbirth

The current study investigated the contributive role of perinatal dissociative and perinatal emotional responses to the development of PTSD symptoms following childbirth.

METHOD

Using a prospective, longitudinal design, 140 women were studied who were followed from the first week after delivery to three months postpartum.

RESULTS

Three women (2.1%) met criteria for PTSD and 21.4% reported a traumatic childbirth experience. Both perinatal negative emotional reactions and perinatal dissociative reactions were the predictors of PTSD symptoms at three months postpartum. The effect of perinatal dissociation, however, was partially mediated by perinatal emotional reactions.

CONCLUSION

Posttraumatic stress disorder can be a consequence of the experience of childbirth. Women who reported high levels of negative emotions during and shortly after childbirth were more likely to develop PTSD symptoms than women who did not. Women who experienced an instrumental delivery and also reported higher levels of psychoform perinatal dissociation, were at higher risk than women who reported higher levels of perinatal dissociation during a spontaneous delivery. These findings add to the growing body of literature regarding traumatic childbirth and indicate that perinatal dissociative and emotional phenomena are associated with posttraumatic stress.

Daily stress and concept of self in Swedish ambulance personnel

INTRODUCTION

This study investigated the prevalence of post-traumatic stress symptoms among professional ambulance personnel in Sweden and investigated the question: "Does self-knowledge have influence on how well one copes with the effects of daily work exposure from such events?" Little is known about the variables that might be associated with post-traumatic stress symptoms in high-risk occupational groups such as ambulance service groups.

METHODS

Data were gathered from ambulance personnel by means of an anonymous questionnaire. Survey responses of 362 ambulance personnel from the county of Västra Götaland were analyzed. A correlation was established between post-traumatic symptoms using the impact of event scale (IES-15) and the Professional Self-Description Form (PSDF).

RESULTS

Of those who reported a traumatic situation, 21.5% scored > or =26 on the IES-15 subscale. Scores >26 indicate "PTSD caseness". There were significant differences on PSDF subscales between those presenting with or without post-traumatic symptoms.

CONCLUSIONS

The mental health and emotional well-being of ambulance personnel appear to be compromised by accident and emergency work. The high prevalence of PTSD symptoms in ambulance personnel indicates an inability to cope with post-traumatic stress caused by daily work experiences.

Trauma-related dissociation: conceptual clarity lost and found

OBJECTIVE

Imprecise conceptualizations of dissociation hinder understanding of trauma-related dissociation. An heuristic resolution for research and clinical practice is proposed.

METHOD

Current conceptualizations of dissociation are critically examined. They are compared with a new theory that incorporates classical views on dissociation with other contemporary theories related to traumatization, viewing dissociation as a lack of integration among psychobiological systems that constitute personality, that is, as a structural dissociation of the personality.

RESULTS

Most current views of dissociation are overinclusive and underinclusive. They embrace non-dissociative phenomena--rigid alterations in the level and field of consciousness--prevalent in non-traumatized populations, and which do not require structural dissociation. These views also largely disregard somatoform and positive symptoms of dissociation and underestimate integrative deficiencies, while emphasizing the psychological defensive function of dissociation. They do not offer a common psychobiological pathway for the spectrum of trauma-related disorders. Structural dissociation of the personality likely involves divisions among at least two psychobiological systems, each including a more or less distinct apperceptive centre, that is, a dissociative part of the personality. Three prototypical levels of structural dissociation are postulated to correlate with particular trauma-related disorders.

CONCLUSIONS

Limitation of the concept of dissociation to structural dividedness of the personality sets it apart from related but non-dissociative phenomena and provides a taxonomy of dissociative symptoms. It postulates a common psychobiological pathway for all trauma-related disorders. Trauma-related dissociation is maintained by integrative deficits and phobic avoidance. This conceptualization advances diagnosis, classification, treatment and research of trauma-related disorders.

Patients' problems with new medication for chronic conditions

OBJECTIVES

To assess patients' adherence to new medication for a chronic condition (and whether non-adherence was intentional), patients' problems with their medication, and their further information needs.

METHODS

A longitudinal survey with data collection at 10 days and 4 weeks was performed on 258 patients recruited from 23 community pharmacies in south east England. Patients were eligible to participate if they were starting a new chronic medication and were either 75 years or older or had one of the following chronic conditions: stroke, coronary heart disease, asthma, diabetes, and rheumatoid arthritis. At each time point a semi-structured telephone interview was conducted and a postal questionnaire was sent.

MAIN OUTCOME MEASURES

Self-reported adherence, causes of non-adherence, problems with medication, information needs.

RESULTS

Sixty seven (30%) of 226 patients still taking their medication at 10 days and 43 of 171 (25%) still taking their medication at 4 weeks were non-adherent. At 10 days 55% of the non-adherence was unintentional and the remainder was intentional; these proportions were similar at 4 weeks. 138 of 208 (66%) participants still taking their new medication at 10 days reported at least one problem with it. 137 of 226 patients (61%) expressed a substantial and sustained need for further information at 10 days and 88 of 171 (51%) at 4 weeks. Several patients who were adherent or reported no problems at 10 days were non-adherent or had problems at 4 weeks.

CONCLUSIONS

A significant proportion of patients newly started on a chronic medication quickly become non-adherent, often intentionally so. Many have problems with their medication and information needs. Patients need more support when starting on new medication for a chronic condition and new services may be required to provide this.

Relationship between child abuse history, trauma, and dissociation in Russian college students

OBJECTIVE

The research was conducted to determine the relationship between violent trauma, child abuse history, and dissociative symptoms in a Russian population.

METHOD

Three hundred and one undergraduate students from Moscow State Linguistics University participated in the study and completed the Dissociation Continuum Scale, the Violence History Questionnaire, the Traumatic Events Survey (TES), and a demographic measure.

RESULTS

Scores on dissociation and its subfactors were significantly higher in the Russian sample compared to the normative US group. The best predictors for dissociation were experiencing a violent trauma, child abuse history, and/or the experience of a fearful event. Those participants with a prior child abuse history were more symptomatic after adult trauma than those with no such history.

CONCLUSIONS

The relationship between trauma/abuse and dissociation is unlikely to be a result of suggestion by therapists or media exposure, since the correlation appears in a Russian population who are relatively unexposed to these suggestive sources. The validity, reliability, and structure of the dissociation measure were relatively similar in American and Russian samples.

Innere Kapitulation beim komplexen Problemlösen: Dissoziative versus integrative Verarbeitungsstrategien

Zusammenfassung: Überforderung durch komplexe Problemsituationen kann einen multimodalen Zustand innerer Kapitulation auslösen. Dieser Zustand beschränkt sich nicht nur auf den Verlust an Situationskontrolle, er umfasst auch Merkmale wie Reduzierung des Selbstsicherheitsgefühls, der positiven Stimmung und Erfolgszuversicht sowie die Steigerung der negativen Stimmung u. a. m. Es werden ein Entstehungsmodell der “Inneren Kapitulation”, das auf der Grundlage der Theorie der Persönlichkeits-System-Interaktionen ( Kuhl, 1998 , 2000 , 2001 ) entwickelt wurde, sowie individuelle Unterschiede bei der Verarbeitung negativer Erlebnisse diskutiert. Erste Ergebnisse einer Untersuchung auf der Basis der von Dörner und Mitarbeitern entwickelten Computersimulation “Feuer” werden zusammengefasst und in Bezug auf Prädiktoren der “Inneren Kapitulation” diskutiert.

Predictors of acute distress among young adults injured by community violence

Acute reactions to trauma are examined in 267 individuals severely injured via community violence. Respondents were interviewed about pretrauma, peritraumatic, and acute posttraumatic factors. A series of bivariate and multivariate analyses were conducted. We found few factors related to peritraumatic dissociation (PD): only injury severity and neuroticism emerged as multivariate predictors and the effects were small. PD was strongly related to acute PTSD symptoms, and partially mediated the relationship between other factors and acute PTSD and general distress symptoms. Different patterns of predictors emerged for acute PTSD symptoms vis-à-vis general distress symptoms. Future research on predictors of PD is indicated to develop prevention and early intervention programs.

Posttraumatic distress and coping strategies among rescue workers after an earthquake

Disaster workers are at high risk for developing psychiatric morbidity. This study examined the prevalence rates of psychiatric and posttraumatic distress and the relationship between psychiatric and posttraumatic morbidity and coping strategies among rescue workers following an earthquake in Taiwan on September 21, 1999. Eighty-four male firefighters who had been exposed to earthquake rescue work were assessed 5 months after the event. The Chinese Health Questionnaire (CHQ), the Impact of Event Scale (IES), and the Ways of Coping Questionnaire (WCQ) were used to assess psychiatric morbidity, posttraumatic morbidity, and coping strategies. The observed prevalence rates were 16.7% and 21.4% for general psychiatric morbidity and posttraumatic morbidity, respectively. Results from multivariate logistic regression indicated that job experience and confrontive coping were significant predictors of psychiatric morbidity, while job experience, distancing, escape-avoidance, and positive reappraisal were significant predictors of posttraumatic morbidity. Rescue workers with longer job experience were at the highest risk for developing psychiatric and posttraumatic distress.

Secondary traumatic stress effects of working with survivors of criminal victimization

This paper focuses on the consequences for providers of working with survivors of traumatic events, particularly criminal victimization. The paper reviews the relevant research and treatment literature associated with secondary traumatic stress (STS) and related variables (burnout, compassion fatigue, vicarious trauma, and countertransference). The latter part of the paper identifies the most important mitigating factors in the development of STS. These include good training specific to trauma work, a personal history of trauma, and the interpersonal resources of the worker. Implications for treatment, prevention, and research are discussed.

Peritraumatic dissociation and PTSD severity: do event-related fears about death and control mediate their relation?

Relations among peritraumatic dissociation, PTSD severity, event-related fear (i.e. fear experienced during traumatic event) about death, and event-related fear about losing control were examined in the current study. Particular emphasis was placed on testing whether or not fears about death and losing control mediate the relation between peritraumatic dissociation and PTSD severity in a sample of 146 nontreatment-seeking university women. Results indicated that event-related fears about death and losing control accounted for the relation between peritraumatic dissociation and PTSD severity; that is, the effect of peritraumatic dissociation on PTSD severity was eliminated after controlling for these fears. Speculations about findings are discussed.
