Dokkedahl SB, Lahav Y. Peritraumatic dissociation and posttraumatic stress symptoms: the moderating role of perceived threat. Eur J Psychotraumatol 2024; 15:2338670. [PMID: 38618677 PMCID: PMC11020594 DOI: 10.1080/20008066.2024.2338670] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 03/27/2024] [Indexed: 04/16/2024] Open
Abstract
Background: Although peritraumatic dissociation (PD) is viewed as a risk factor for posttraumatic stress disorder (PTSD), prospective studies taking into account other well-known risk factors for PTSD have been scarce, and the exploration of potential moderators within the relations between PD and PTSD has been lacking.Objective: Filling this gap, this prospective study explored the moderating role of perceived threat within the relations between PD and PTSD, above and beyond age, gender, education, and early trauma-related symptoms.Method: A convenience sample of 200 Israeli civilians filled out self-report questionnaires during the peritraumatic phase (T1) and one to two months after the posttraumatic phase (T2) of being exposed to rocket attacks.Results: The results showed that perceived threat and PD were associated with early trauma-related symptoms and PTSD symptoms. Moreover, perceived threat moderated the relationship between PD and all PTSD symptom clusters apart from avoidance.Conclusions: The present results suggest that the implications of PD are shaped by levels of perceived threat, so that detriments of PD are evident when the trauma is appraised as being highly threatening. Therefore, early interventions that aim to decrease PD may be beneficial in preventing PTSD symptoms of intrusion, hyper arousal, and negative alterations in mood and cognition, for individuals who perceive traumatic events as highly threatening.

Biological and psychological predictors of posttraumatic stress disorder onset and chronicity. A one-year prospective study. Neurobiol Stress 2016; 3:61-67. [PMID: 27981178 PMCID: PMC5146193 DOI: 10.1016/j.ynstr.2016.02.002] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2015] [Revised: 02/01/2016] [Accepted: 02/02/2016] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Few studies have prospectively examined risk factors for posttraumatic stress disorder (PTSD) in the aftermath of a traumatic exposure. The aim of this study is to identify the concurrent influence of psychological and biological diatheses on PTSD onset and maintenance, taking into account socio-demographic factors and psychiatric antecedents. METHODS A total of 123 civilians (61.8% of women) recruited in emergency units, were assessed using validated instruments during the first week and then at 1, 4, and 12 months post-trauma. Baseline assessment included evaluation of the psychological diathesis (i.e. psychiatric history and peritraumatic distress and dissociation), and the biological diathesis [i.e. cortisol, norepinephrine, epinephrine, c-reactive protein, total cholesterol, HDL cholesterol, glycosylated haemoglobin, waist-to-hip ratio (WHR), body mass index, diastolic and systolic blood pressure (SBP), and heart rate]. RESULTS Multivariate logistic regression analyses demonstrated both psychological and biological diatheses to be independent risk factors for PTSD. Peritraumatic distress and dissociation predicted onset (1-month) and mid-term PTSD (4-months), respectively. PTSD risk was associated positively with SBP and negatively with WHR, throughout the follow-up. In addition, a higher level of 12 h-overnight urinary norepinephrine independently predicted mid-term PTSD (4-months). CONCLUSIONS This prospective study shows that peritraumatic psychological and biological markers are independent predictors of PTSD onset with specificities according to the stage of PTSD development; the psychological diathesis, i.e. peritraumatic distress and dissociation, being a better predictor of short-term dysfunction whereas biological diathesis was also predictive of development and maintenance of PTSD.

[PMID: 23103082 DOI: 10.1016/j.injury.2012.10.001] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2012] [Revised: 09/17/2012] [Accepted: 10/01/2012] [Indexed: 02/02/2023]
Abstract
BACKGROUND Acute physical injury may lead to psychological distress. The relationship between peritraumatic responses, injury severity, the personality trait of optimism/pessimism and psychological distress is not fully understood. In addition, the development of post-traumatic stress symptoms may differ in subgroups. METHODS One hundred and eighty-one patients (18-65 years) completed questionnaires 1 (baseline), 3 and 12 months after first admission for acute physical injury. All patients were conscious on arrival. Scores on the Casualty Chain Inventory (CCI) for peritraumatic responses, the Impact of Event Scale (IES), the Hospital Anxiety and Depression Scale (HADS), the Life Orientation Test-Revised (LOT-R), trauma-related variables (ISS, Abbreviated Injury Scale [AIS], Glasgow Coma Scale [GCS]), and background variables were assessed. RESULTS Mean IES scores were 21.5 (95% CI: 19.0-24.0) at baseline and 15.8 (13.5-18.1) at 12 months (p<0.001). One subgroup (delayed onset, 12.2%) had an increase of at least 10 points in the IES score and another subgroup (chronic, 13.3%) had high and persistent post-traumatic stress symptoms during the follow-up period. At baseline, 45.3% had an IES score ≥ 20, indicating possible clinical case levels, compared with 33.1% at 12 months. Accordingly, 14% had anxiety symptoms and 10.8% had depression symptoms at a case level (HADS ≥ 8) at one-year follow-up. Mutually independent predictors of post-traumatic stress symptoms at 12 months were dissociation (OR 1.3, 95% CI: 1.1-1.6) and perception (OR 1.1, 95% CI: 1.0-1.3) measured by the CCI. Being in work before injury (OR 0.1, 95% CI: 0.02-0.4) and higher educational level (OR 0.3, 95% CI: 0.1-0.7) were associated with fewer IES symptoms. Dissociation and having a pessimistic trait predicted anxiety and depression at 12 months. Previous psychiatric problems predicted anxiety symptoms, and high educational level predicted less depression symptoms. CONCLUSION One-third of conscious physical injured patients had post-traumatic stress symptoms at a possible clinical case level one year after the traumatic event, and one-third of these had delayed onset. Symptoms of peritraumatic dissociation and perception were mutually independent predictors of psychological distress.

Abstract
Extensive research has identified stereotypic behavioral and biological abnormalities in post-traumatic stress disorder (PTSD), such as heightened autonomic activity, an exaggerated startle response, reduced basal cortisol levels and cognitive impairments. We have reviewed primary research in this area, noting that factors involved in the susceptibility and expression of PTSD symptoms are more complex and heterogeneous than is commonly stated, with extensive findings which are inconsistent with the stereotypic behavioral and biological profile of the PTSD patient. A thorough assessment of the literature indicates that interactions among myriad susceptibility factors, including social support, early life stress, sex, age, peri- and post-traumatic dissociation, cognitive appraisal of trauma, neuroendocrine abnormalities and gene polymorphisms, in conjunction with the inconsistent expression of the disorder across studies, confounds attempts to characterize PTSD as a monolithic disorder. Overall, our assessment of the literature addresses the great challenge in developing a behavioral and biomarker-based diagnosis of PTSD.

Abstract
OBJECTIVE This study aimed to evaluate the predictive factors of the emergence of complete PTSD and subsyndromal PTSD (defined as individuals exposed to a traumatic event with at least one psychopathological impact, such as hyperarousal, avoidance or persistent re-experiencing) following a motor vehicle accident (MVA). METHODS We recruited 155 adult MVA patients, physically injured and admitted to trauma service, over two years. In the week following the accident, patients were asked to complete questionnaires assessing their social situation (sex, age, marital and employment status, prior MVA or trauma), comorbidity (MINI), distress (PDI) and dissociation (PDEQ) experienced during and immediately after the trauma. An evaluation using the CAPS was conducted six months after the trauma to assess a possible PTSD. RESULTS At six months, 25.8% of the participants developed subsyndromal symptoms and 7.74% developed complete PTSD. The three symptoms that best discriminated the groups were dysphoric emotion, perceived life threat and dissociation. Logistic regression results showed that the strongest predictor of PTSD was the perceived life threat. In addition, a dimensional approach to the results revealed significant correlations between (1) peritraumatic distress and persistent re-experiencing or hyperarousal and (2) dissociation score and avoidance strategy. The presence of a prior traumatic event reinforces avoidance strategies. CONCLUSIONS Our results stress that peritraumatic factors (especially the perception of a life threat) are good predictors of PTSD development. A dimensional perspective allows better identification of psychological complications following an MVA.

Abstract
This study investigated the predictive value of pretraumatic and peritraumatic variables and early PTSD-like symptoms (within 48 h post-event) in determining the severity of posttraumatic stress in accident victims. Symptom development appears to be related to initial PTSD-like reactions, while demographic variables play a role in predicting symptom severity 6 months post-event.

Abstract
Mindfulness- and acceptance-based conceptualizations of PTSD implicate experiential avoidance and non-mindful behavior in the etiology and maintenance of the disorder. If experiential avoidance is associated with vulnerability to PTSD, then a mindful and accepting orientation toward experience may confer psychological resilience following exposure to trauma. This article examines how mindfulness- and acceptance-based theories of psychopathology relate to risk of and resilience to PTSD. Research is reviewed dealing with the impact of experiential avoidance, avoidant coping, dissociation, acceptance, and mindfulness on PTSD symptom severity and posttraumatic functioning. This review suggests that trait mindfulness and acceptance are associated with greater psychological adjustment following exposure to trauma, while experiential avoidance, persistent dissociation, and coping strategies involving emotional disengagement are associated with greater PTSD symptom severity and related psychopathology. Methodological challenges are explored and suggestions for future research and PTSD prevention programs are discussed.

Abstract
The current study examined cognitive-emotional distinctiveness (CED), the extent to which emotions are linked with event information, in memories associated with PTSD. Participants either with PTSD (n=68) or without PTSD (n=40) completed a modified multidimensional scaling technique to measure CED for their most negative and most positive events. The results revealed that participants in the PTSD group evidenced significantly lower levels of CED. This group difference remained significant when we limited the analysis to traumatic events that led to a PTSD diagnosis (n=33) in comparison to control participants who nominated a traumatic event that did not result in PTSD (n=32). Replicating previous findings, CED levels were higher in memories of negative events, in comparison to positive events. These results provide empirical evidence that memories associated with PTSD do contain special organizational features with respect to the links between emotions and memory. Implications for understanding and treating PTSD are discussed.

Abstract
Peritraumatic dissociation (PD) and experiential avoidance (EA) have been implicated in the etiology of posttraumatic stress symptomatology (PTSS); however, the function of these two factors in the onset and maintenance of PTSS following a potentially traumatic event is unclear. The temporal relationships between EA, PD, and the four clusters of PTSS proposed by the Simms/Watson dysphoria model (Simms, Watson, & Doebbeling, 2002) were examined in a three-wave prospective investigation of 532 undergraduate women participating in an ongoing longitudinal study at the time of a campus shooting. Path analyses indicated that preshooting EA predicted greater PD, intrusions, and dysphoria symptoms approximately one month postshooting. PD was associated with increased symptomatology across all four clusters 1-month postshooting, while 1-month postshooting EA was associated with higher dysphoria and hyperarousal symptoms eight months postshooting. PD had a significant indirect effect on all four PTSS clusters eight months postshooting via 1-month postshooting symptom reports. The results suggest that both EA and PD show unique influences as risk factors for PTSS following a potentially traumatic event.

Abstract
BACKGROUND Peritraumatic psychological- and sensory impressions in victims of civilian accidents are only partly understood. This study scrutinizes the level and duration of perceived psychological threat at scene of injury as well as in hospital (the casualty chain) measured by the Casualty Chain Inventory (CCI). The purpose of the study was to assess and validate the CCI, and to examine the correlations between the new instrument and stress responses measured by the Impact of Event Scale (IES) and the Post-traumatic Stress Scale-10 (PTSS-10) METHODS Three hundred and fifteen injured, conscious, hospitalised patients were assessed with a self-report questionnaire. The CCI consists of eight items including sensory impressions and well-known psychological responses to trauma. RESULTS The internal consistency of the CCI was solid (Cronbach's alpha: .83-.85). A factor analysis revealed two components, "perception" and "dissociation". The instrument correlates significantly with the Impact of Event Scale (r = 0.47 - 0.54) and the Posttraumatic Stress Scale-10 (r = 0.32 - 0.50). The explained variance is high both at the scene of injury (61%) and in the hospital (65%). Dissociation and perception either used as a two-factor solution or as a sum score measured in the hospital, gave the strongest prediction for later psychological distress. CONCLUSIONS The CCI appears to be a useful screening instrument for, at an early state, identifying patients hospitalized after a physical incident at risk for subsequent psychological distress.

Abstract
BACKGROUND The aim of this study was to examine the role of pre-trauma, traumatic event, and peri-traumatic psychological characteristics on post-motor vehicle accident (MVA) Posttraumatic Stress Disorder (PTSD) and depression. METHODS The sample comprised 333 (54% female) hospital accident and emergency attendees who completed a self-report postal screening survey approximately 1-month post-accident and 128 (62% female) participants who completed a follow-up survey at 3-months. RESULTS Path analysis (Model 1) showed that dissociation partially mediated the relationship between past emotional problems and initial post-MVA distress, as well as between fear of dying and levels of distress. Level of alertness and perceived accident severity had no direct effects on post-MVA distress. However, higher levels of exposure contributed to distress predominantly in the presence of high levels of fear and subsequent dissociative experiences. When ongoing PTSD and depression symptoms were included (Model 2), feeling depressed/sad at 1-month was the strongest predictor of both PTSD and depression symptom severity at 3-months post-MVA, explaining 53% and 40% of the variance, respectively. Dissociation remained an important mediating variable at both time points. CONCLUSIONS These models show the influence of previous emotional vulnerability factors and the important mediating role of peri-traumatic experiences (in the presence of fear due to increased levels of accident severity) on post-MVA morbidity. Additionally, MVA survivors who report feeling depressed/sad 1-month after their accident are at greater risk of developing both PTSD and depression.

Abstract
Our aim was to assess the influence of the coping strategies employed for the management of traumatic events on the occurrence of dissociation and traumatic disorders. We carried out a 1-year retrospective study of the cognitive management of a traumatic event in 18 subjects involved in the same road vehicle accident. The diagnosis of post-traumatic stress disorder (PTSD) was made for 33.3% of the participants. The participants with a PTSD diagnosis 1 year after the event used emotion-centered strategies during the event more often than did those with no PTSD, P < 0.02. In the year after the traumatic event, our results show a strong link between the intensity of PTSD and the severity of the post-traumatic symptoms like dissociation (P = 0.032) and the use of emotion-centered strategies (P = 0.004). Moreover, the participants who presented Peritraumatic Dissociative Experiences Questionnaire scores above 15 made greater use of emotion-centered coping strategies than did those who did not show dissociation, P < 0.04. Our results confirm that the cognitive management of traumatic events may play an essential role in the development of a state of post-traumatic stress in the aftermath of a violent event.

Abstract
BACKGROUND Motor vehicle accidents (MVAs) are the main cause of Posttraumatic stress disorder (PTSD) in industrialized countries. This includes the frequently occurring but understudied situation of parents learning that their children were injured. However, unlike in other types of trauma survivors, little is known about the predictors of PTSD symptoms in mothers whose child has suffered an MVA. METHODS A group of 72 mothers and 28 fathers were prospectively assessed for peritraumatic distress, peritraumatic dissociation, and PTSD symptoms 1 and 5 weeks after their child had suffered an MVA. RESULTS Levels of peritraumatic distress and dissociation were comparable to other trauma victims, 18% of the mothers were considered to be suffering from probable PTSD. In mothers, significant positive correlations were found between PTSD symptoms and peritraumatic distress (r=.34) and dissociation (r=.37), whereas mothers' PTSD symptoms were associated with decreased peritraumatic dissociation in fathers (r=-.37). Even after controlling for covictim/witness status, peritraumatic distress was a predictor of mothers' PTSD symptoms, explaining 14% of the variance. CONCLUSIONS Peritraumatic response and PTSD symptoms should be routinely assessed among parents whose child has experienced a traumatic event.

Abstract
AIM To study the prevalence of posttraumatic stress disorder (PTSD), anxiety and depression in parents three months after pediatric intensive care treatment of their child and examine if peritraumatic dissocation and coping styles are related to these mental health problems. METHODS This is a prospective cohort study and included parents of children unexpectedly admitted to the Pediatric Intensive Care Unit (PICU) from January 2006 to March 2007. At three months follow-up parents completed PTSD (n = 115), anxiety and depression (n = 128) questionnaires. Immediately after discharge, parents completed peritraumatic dissocation and coping questionnaires. Linear regression models with generalized estimating equations examined risk factors for mental health problems. RESULTS Over 10% of the parents were likely to meet criteria for PTSD and almost one quarter for subclinical PTSD. Respectively 15% to 23% of the parents reported clinically significant levels of depression and anxiety. Peritraumatic dissocation was most strongly associated with PTSD, anxiety as well as depression. Avoidance coping was primarily associated with PTSD. CONCLUSION A significant number of parents have mental health problems three months after unexpected PICU treatment of their child. Improving detection and raise awareness of mental health problems is important to minimize the negative effect of these problems on parents' well-being.

Abstract
OBJECTIVE This study investigated short-term re-experiencing and avoidance after elective surgical abortion. In addition, it was prospectively investigated whether peritraumatic dissociation and pre-abortion dissociative tendencies and alexithymia predict re-experiencing and avoidance. METHOD In a prospective observational design, Dutch-speaking women presenting for first trimester elective surgical abortion completed self-report measures for dissociative tendency and alexithymia. Peritraumatic dissociation was measured immediately post-abortion. Re-experiencing and avoidance were measured 2 months post-abortion. RESULTS Participants reported moderately elevated levels of re-experiencing and avoidance that exceeded a clinical cut-off point for 19.4% of the participants. Peritraumatic dissociation predicted intrusion and avoidance at 2 months. In addition, avoidance was predicted by the alexithymic aspect of difficulty describing feelings. CONCLUSIONS Re-experiencing and avoidance after elective surgical abortion represent a significant clinical problem that is predicted by peritraumatic dissociation and alexithymia. Psychological screening and intervention might be a useful adjunct to elective abortion procedures.

Abstract
BACKGROUND There is still marked variability in the findings concerning psychiatric disorders associated with traumatic injury. The aim of this study was to determine the incidence of acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) following accidental injuries, and to predict the PTSD symptom level at 6 months, taking into particular consideration the role of pre-existing psychiatric morbidity and insufficient command of the local language. METHOD A total of 255 accident survivors who were hospitalized for at least 2 consecutive nights at a Swiss university hospital for treatment of recently acquired physical injuries were interviewed within 2 weeks of the trauma and 6 months after the accident. Patients who did not have a good command of German but were fluent in Italian, Spanish, Portuguese, Serbo-Croatian or Albanian were assessed using interpreters. The main outcome measure was the Clinician-Administered PTSD Scale. RESULTS Ten patients (3.9%) were diagnosed as having ASD. At 6 months, 8 patients (3.1%) had PTSD. A regression model using 12 potential predictor variables explained 40% of the variance of PTSD symptoms; mild traumatic brain injury (p < 0.001), pain (p < 0.05), ASD symptom level (p < 0.001) and emotional coping (p = 0.001) predicted higher PTSD symptom levels, while high Sense of Coherence (p < 0.05) and perceived responsibility for the accident (p < 0.01) were associated with lower PTSD symptom levels at follow-up. CONCLUSIONS ASD and PTSD seem to occur less frequently following accidental injuries than previously reported in the literature. Pre-existing psychiatric morbidity and lack of proficiency in the locally spoken language do not appear to play an important role in the development of PTSD.

Abstract
This article reviews current research on acute stress disorder (ASD) and posttraumatic stress disorder (PTSD) resulting from pediatric simple (i.e., single, unpredictable, and unintentional) physical injury and how pain may act as both a trigger and a coexisting symptom. Although several studies have explored predictors of ASD and PTSD, as well as the relationship between these conditions in adults, there is less research on ASD and PTSD in children and adolescents. This review highlights the importance of early detection of pain and acute stress symptoms resulting from pediatric unintentional physical injury in the hopes of preventing long-term negative outcomes, such as the potential development of PTSD and associated academic, social, and psychological problems.

Relations among peritraumatic dissociation and posttraumatic stress: a meta-analysis. Clin Psychol Rev 2008; 28:1138-51.

Abstract
A meta-analysis was performed on the empirical literature which addressed the relationship of peritraumatic dissociation to posttraumatic stress (PTS). Extensive literature searches were conducted to identify as many relevant studies as possible, and revealed 59 independent eligible studies. All studies were coded using a detailed code sheet that included effect measures, variables that indicated the methodological quality of the studies, and substantial variables that might theoretically affect the relationship between peritraumatic dissociation and PTS. A significant positive relation between peritraumatic dissociation and PTS was found. Differences in the methodological rigor between studies - time elapsed since peritraumatic dissociation, design, sample type, and study type - significantly and sufficiently explained the variability in effect sizes between studies. Theoretical variables did not explain such variability. Although results underline earlier findings, due to designs of the reviewed studies no conclusions could be drawn as to causal relations between peritraumatic dissociation and PTS.

Abstract
We conducted a systematic review of prospective studies examining the independent predictive value of peritraumatic dissociation (PD) for posttraumatic stress disorder (PTSD) symptomatology following single traumatic events. Insight into the independent predictive value may help to identify victims at risk for PTSD symptomatology. For this purpose a literature search was carried out using the online databases PsycINFO, Medline/Pubmed, and PILOTS. Studies were included if they were published in peer-reviewed journals (before 2007), focused on more or less single traumatic events (Type I trauma), assessed PD within 1 month, had follow-ups 3 months or later, and which controlled for mental health problems at the time PD was assessed. The majority of the 17 identified studies showed no or only weak indications of an independent predictive value of PD for PTSD symptomatology following type I traumas. Only 3 of the 6 studies with positive results reported a strong independent predictive value of PD. Although bivariately associated with PTSD symptomatology, there is no general consensus across prospective Type I trauma studies that PD qualifies as an important independent predictor of PTSD symptomatology. Results indicate that initial mental health problems, among other factors, are better predictors of PTSD symptomatology than PD.

Abstract
Earlier findings of a positive correlation between heart rate (HR) and posttraumatic symptom level have recently been brought into question. Therefore, we investigated the relationship between resting HR and symptom scores of posttraumatic stress disorder (PTSD) in physically injured accident survivors, controlling for well established predictors for (PTSD and factors influencing HR. A representative sample of 255 accident victims was assessed measuring PRIME-MD, PDEQ, trauma-related cognitions and CAPS. Initial interviews were conducted five days post trauma; follow-up assessments took place six months later. Heart rate measurements were obtained from surgical files. We found positive bivariate correlations between HR at hospital admission (HRA) and PTSD symptom levels. However, in multiple regression analysis HRA contributed marginally to the prediction of PTSD symptom levels. We conclude that the initial heart rate is a weak and not independent predictor for PTSD symptom level following accidental injuries.
