Enhancing Agency in Posttraumatic Stress Disorder Therapies Through Sensorimotor Technologies.

Posttraumatic stress disorder (PTSD) is a significant public health concern, with only a third of patients recovering within a year of treatment. While PTSD often disrupts the sense of body ownership and sense of agency (SA), attention to the SA in trauma has been lacking. This perspective paper explores the loss of the SA in PTSD and its relevance in the development of symptoms. Trauma is viewed as a breakdown of the SA, related to a freeze response, with peritraumatic dissociation increasing the risk of PTSD. Drawing from embodied cognition, we propose an enactive perspective of PTSD, suggesting therapies that restore the SA through direct engagement with the body and environment. We discuss the potential of agency-based therapies and innovative technologies such as gesture sonification, which translates body movements into sounds to enhance the SA. Gesture sonification offers a screen-free, noninvasive approach that could complement existing trauma-focused therapies. We emphasize the need for interdisciplinary collaboration and clinical research to further explore these approaches in preventing and treating PTSD.

Peritraumatic dissociation and posttraumatic stress symptoms: the moderating role of perceived threat.

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.

Breaking the Silence: Exploring Peritraumatic Distress and Negative Emotions in Male and Female Physical Domestic Violence Victims.

Background: Domestic violence is a widespread problem affecting individuals, families, and communities worldwide. Peritraumatic distress is associated with post-traumatic stress disorder and other mental health problems among victims, but research on men's experiences is limited. Objective: We analyzed data from 48 physical domestic violence victims (16 males and 32 females) to compare their levels of peritraumatic distress and negative emotions, and to examine the types of aggressors they faced. Methods: We used descriptives to summarize sample characteristics and Peritraumatic Distress Inventory scores and used statistical tests such as Mann-Whitney U, Shapiro-Wilk, Levene's test, contingency tables, and chi-square to investigate differences and associations between variables. Results: Female victims of domestic violence had significantly higher scores on the Peritraumatic Distress Inventory than male victims and experienced significantly higher levels of negative emotions than male victims, including impotence/inability to react, sadness, anger/frustration, loss of control, fear, guilt, and shame. Husbands and domestic partners were the most frequent aggressors against female victims, while wives and ex-wives were the most frequent aggressors against male victims. In addition, partners were found to be the most frequent type of aggressor in the sample. Descriptive statistics, box plots, and scatter plots were used to provide a clear picture of the sample characteristics. Conclusion: Female victims of domestic violence reported higher levels of peritraumatic distress and negative emotions compared to men victims. Partners were the most frequent type of aggressor in the sample.

Modeling the structural relationships between trauma exposure with substance use tendency, depression symptoms, and suicidal thoughts in individuals with earthquake trauma experience: the mediatory role of peritraumatic dissociation and experiential avoidance.

BACKGROUND: Despite the fact that studies indicate that earthquake trauma is associated with numerous psychological consequences, the mediating mechanisms leading to these outcomes have not been well-studied. Therefore, this study investigates the relationship between trauma exposure with substance use tendency, depression, and suicidal thoughts, with the mediating role of peritraumatic dissociation and experiential avoidance. METHODS: The descriptive-correlational approach was employed in this study. The participants were people who had experienced the Kermanshah earthquake in 2017. A total of 324 people were selected by convenient sampling method. The Traumatic Exposure Severity Scale, the Peritraumatic Dissociative Experiences Questionnaire, the Acceptance and Action Questionnaire, the Iranian Addiction Potential Scale, Beck's Depression Inventory [BDI-II], and Beck's Suicidal Thoughts Scale were used to collect data. The gathered data was analyzed| using structural equation modeling in |SPSS Ver. 24 and LISREL Ver. 24. RESULTS: The study findings indicated that the intensity of the trauma exposure is directly and significantly associated with depression symptoms, peritraumatic dissociation, and experiential avoidance. The severity of exposure to trauma had a significant indirect effect on the tendency to use substances through experiential avoidance. This is while the severity of the trauma experience did not directly correlate with substance use and suicidal thoughts. In addition, peritraumatic dissociation did not act as a mediator in the relationship between the severity of trauma exposure with substance use, depression, and suicidal thoughts. CONCLUSIONS: The severity of exposure to the earthquake was associated with symptoms of depression and these findings indicate the importance of experiential avoidance in predicting the tendency to use drugs. Hence, it is essential to design and implement psychological interventions that target experiential avoidance to prevent drug use tendencies and to establish policies that lower depression symptoms following natural disasters.

The relationship between peritraumatic distress, mental health symptoms, and functioning impairment in healthcare workers during the COVID-19 emergency.

OBJECTIVE: Healthcare workers (HCWs) were considered a population at risk for developing psychiatric symptoms during the COVID-19 pandemic, such as anxiety, depression, and post-traumatic stress disorder (PTSD). Peritraumatic distress is associated with post-traumatic psychopathological symptoms; however, little is known about how it may affect functioning. The study aimed at evaluating the level of peritraumatic distress in a sample of HCWs during the first wave of the COVID-19 pandemic and at examining the relationship between peritraumatic distress, mental health symptoms, and functioning impairment. METHODS: A sample of 554 frontline HCWs were consecutively enrolled in major university hospitals and community services in Italy. The PDI, IES-R, PHQ-9, and GAD-7 were used to assess peritraumatic distress, symptoms of PTSD, depression, and anxiety, respectively, and the WSAS to investigate functioning impairment. PDI scores were higher among females, community services, physicians, and nurses. Furthermore, the PDI correlated significantly with the GAD-7, PHQ-9, IES-R, and WSAS. RESULTS: In a mediation analysis, the direct effect of PDI on WSAS and the indirect effects through the PHQ-9 and IES-R were statistically significant (P < .001). CONCLUSION: Peritraumatic distress reported by HCWs was associated with symptoms of PTSD, depression, and anxiety, but the association with reduced functioning may be only partially mediated through symptoms of depression and PTSD.

Effects of peritraumatic reactions on post-traumatic stress among Kahramanmaras earthquake survivors.

PURPOSE: Peritraumatic reactions play a crucial role in the development of mental health problems, including depression and post-traumatic stress disorder. Therefore, this study sought to examine the influence of the peritraumatic reactions, including peritraumatic dissociation, peritraumatic distress, mental defeat, and tonic immobility, on post-traumatic stress disorder and major depressive disorder in earthquake survivors. MATERIALS AND METHODS: A total of 261 adult participants aged between 18 and 65 (Mage=29.20, SD = 28.06, 162 were female, and 99 were male) who were exposed to the Kahramanmaras earthquake in February 2023 were recruited in the study. Data were collected between April 10 and 18 2023, two months after the earthquake. Participants completed questionnaires, including The International Trauma Questionnaire, The International Depression Questionnaire, The Mental Defeat Questionnaire, The Tonic Immobility Scale, and The Peritraumatic Dissociative Experiences Questionnaire. RESULTS: Two-step multiple linear regression analyses indicated all peritraumatic reactions predicted both post-traumatic stress disorder and depression. Dominance analysis results showed that the contribution of peritraumatic dissociation in predicting PTSD and depression was higher among other peritraumatic reactions. CONCLUSION: The findings of the study revealed a robust association between peritraumatic reactions and both depression and PTSD, shedding light on the underlying processes in the development of trauma-related disorders. Early assessment of peritraumatic reactions may be useful in identifying individuals at risk of developing PTSD and depression.

Peripartum dissociation, sense of control, postpartum posttraumatic stress disorder and emotional adjustment to motherhood in adult survivors of childhood maltreatment.

Survivors of childhood maltreatment (CM) may experience difficulties in the peripartum period and in adjustment to motherhood. In this study we examined a model wherein CM is associated with maternal self-efficacy and maternal bonding three months postpartum, through mediation of peripartum dissociation and reduced sense of control during childbirth and postpartum-posttraumatic-stress disorder (P-PTSD). Women were recruited in a maternity ward within 48 h of childbirth (T1, N = 440), and contacted three-months postpartum (T2, N = 295). Participants completed self-report questionnaires: peripartum dissociation, sense of control (T1), and CM, P-PTSD, postpartum-depression, maternal self-efficacy and bonding (T2). Obstetrical data were collected from medical files. Structural equation modeling was conducted to test the hypothesized model, controlling for mode of delivery and postpartum-depression. Reported CM included child emotional neglect (CEN; 23.5%), child emotional abuse (CEA; 16.3%), child sexual abuse (CSA; 12.9%) and child physical abuse (CPA; 7.1%). CM was positively associated with peripartum dissociation and P-PTSD (p < .001). Peripartum dissociation was positively associated with P-PTSD (p < .001). P-PTSD was negatively associated with maternal self-efficacy (p < .001) and maternal bonding (p < .001). Association between CM and maternal self-efficacy and bonding was serially mediated by peripartum dissociation and P-PTSD, but not by sense of control. Findings remained significant after controlling for mode of delivery and postpartum-depression. CM is a risk factor for adjustment to motherhood, owing to its effects on peripartum dissociation and P-PTSD. Implementation of a trauma-informed approach in obstetric care and recognition of peripartum dissociative reactions are warranted.

Knowledge, Concerns, and Psychological Distress Among Caregivers of Patients Seeking Emergency Medical Care for Non-COVID-19-Related Illness During the COVID-19 Pandemic: A Cross-Sectional Study.

Introduction During the active phase of the COVID-19 pandemic, the global healthcare system failed to meet the increased demand for healthcare resources, infrastructures, and facilities. The brunt of the healthcare crisis was faced not only by COVID-19 victims; a large majority of non-COVID patients were deprived of routine and emergency care. Factors that possibly affected resource utilization, healthcare-seeking behavior, service delivery patterns, and national health systems' priority during the pandemic were the knowledge and attitudinal concerns related to the COVID-19 disease and its control measures. Here, we evaluated the knowledge, concern, and psychological distress among the caregivers of the patients attending the emergency department at a tertiary healthcare center in India.​ Methodology We conducted a survey-based study using a pre-validated questionnaire on the caregivers of the patients visiting the emergency department (ED) from June to September 2020 (during the first wave of the COVID-19 pandemic). The demographic details and responses of the participants were documented in the semi-structured proforma. A pre-validated COVID-19 Peritraumatic Distress Index (CPDI) questionnaire was used to assess psychological stress. Results Out of 1014 participants interviewed, the majority were male attendants (72%), aged 18-45 (82%), and seeking medical attention for patients with chronic illnesses (76%). Acute onset emergencies like stroke, myocardial infarction, trauma, etc. were the ED presentation in only one-fifth of patients. COVID-19-related knowledge was adequate for questions related to age groups at risk for the viral infection (97% agreed that all age groups were at risk), mode of transmission (75-90% were aware of the common modes of transmission), and >65% knew the common symptoms of COVID-19 infection. However, only 38.5% knew about frequent handwashing as a protective measure. More than half of the participants considered the COVID-19 vaccine as the sole ray of hope and disregarded the effectiveness of alternative medicines such as Ayurvedic/homeopathic/allopathic medicines as preventive options. One-third were first-time visitors to the hospital, while two-thirds of all participants were afraid to visit any hospital during the COVID-19 pandemic. The majority (84%) faced difficulty in accessing the index tertiary care center due to transport, socioeconomic support, or lockdown-related restrictions. In comparison, 60% reported some form of discrimination at almost all levels of healthcare settings due to COVID-19-related priority changes. Nearly half (48%) of all enrolled caregivers reported experiencing mild-to-moderate distress (CPDI score=28-51), and 15.7% felt severe distress (CPDI score >51) while seeking treatment for the non-COVID-19 illness of their patient. Age and socioeconomic status were significantly associated with COVID-19-related psychological distress levels (p<0.001 in logistic regression), while gender, education, and residence showed no significant associations. Conclusion Most of the patient caregivers visiting the emergency department during the COVID-19 pandemic had an adequate understanding of risk factors and preventive measures. The major barriers to accessing healthcare facilities were transport, financial issues, and lockdown-related restrictions. Almost two-thirds of the caregivers revealed mild-to-moderate to severe psychological distress due to the pandemic and lockdown-related concerns.

Peritraumatic Pain in Child Maltreatment: A Systematic Literature Review.

Extensive research has been conducted on the link between trauma, child maltreatment (CM), and chronic pain. Although the risk of suffering from chronic pain among CM survivors has been established, much less is known about the experience of pain during CM incidents or whether such peritraumatic pain sensations are associated with later chronic pain. This scoping review was conducted to synthesize the existing literature on pain during and a short time following CM (i.e., peritraumatic pain). Utilizing the preferred reporting items for systematic reviews and meta-analyses guidelines, the current review included 11 manuscripts, which met the following criteria: (a) refer to physical pain experienced during or a short time after CM, (b) were published in peer-reviewed journals, and (c) were written in English. The review demonstrated that most of the included studies were not intentionally focused on peritraumatic pain, the majority used qualitative research methods, and all were cross-sectional. Furthermore, although validated questionnaires are available, most of the studies did not utilize such measures. Those that intentionally reported pain demonstrated its high intensity and prevalence in CM incidents, indicating that pain is inherently embedded in the experience of maltreatment. The findings spotlight an underdeveloped research realm on a phenomenon that may hold significant empirical, clinical, and legal implications. Research endeavors should initiate interdisciplinary bodies of knowledge to establish well-validated research methodologies that properly quantify peritraumatic pain in trauma and CM.

Peritraumatic physical symptoms and the clinical trajectory of PTSD after a terrorist attack: a network model approach.

Introduction: Following a mass casualty event, such as the Paris terrorist attacks of 13 November 2015, first responders need to identify individuals at risk of PTSD. Physical peritraumatic symptoms involving the autonomic nervous system may be useful in this task.Objective: We sought to determine the trajectory of physical response intensity in individuals exposed to the Paris terrorist attacks using repeated measures, and to examine its associations with PTSD. Using network modelling, we examined whether peritraumatic physical symptom associations differed by PTSD status.Methods: Physical reactions were assessed using the Subjective Physical Reactions Scale at three time points: peritraumatic by retrospective recall, then current at one year (8-18 months) and three years (30-42 months) after the attacks. Interaction networks between peritraumatic physical reactions were compared according to PTSD status.Results: On the one hand, the reported intensity of physical reactions was significantly higher in the PTSD group at all time points. On the other hand, using the dynamic approach, more robust positive interactions between peritraumatic physical reactions were found in the PTSD group one and three years after the attacks. Negative interactions were found in the no-PTSD group at one year. Peritraumatic physical numbness was found to be the most central network symptom in the PTSD group, whereas it was least central in the no-PTSD group.Discussion: Network analysis of the interaction between peritraumatic physical subjective responses, particularly physical numbness, may provide insight into the clinical course of PTSD. Our knowledge of the brain regions involved in dissociation supports the hypothesis that the periaqueductal grey may contribute to the process leading to physical numbing.Conclusions: Our findings highlight the role of peritraumatic somatic symptoms in the course of PTSD. Peritraumatic physical numbness appears to be a key marker of PTSD and its identification may help to improve early triage.

Physical numbness was found to be a central symptom in people developing PTSD in our study examining peritraumatic physical symptoms related to the 2015 Paris terrorist attacks.

Experiencing racial discrimination increases vulnerability to PTSD after trauma via peritraumatic dissociation.

Background: Racial discrimination is a traumatic stressor that increases the risk for posttraumatic stress disorder (PTSD), but mechanisms to explain this relationship remain unclear. Peritraumatic dissociation, the complex process of disorientation, depersonalization, and derealization during a trauma, has been a consistent predictor of PTSD. Experiences of frequent racial discrimination may increase the propensity for peritraumatic dissociation in the context of new traumatic experiences and contribute to PTSD symptoms. However, the role of peritraumatic dissociation in the relationship between experiences of discrimination and PTSD has not been specifically explored.Objective: The current study investigated the role of peritraumatic dissociation in the impact of racial discrimination on PTSD symptoms after a traumatic injury, and the moderating role of gender.Method: One hundred and thirteen Black/African American individuals were recruited from the Emergency Department at a Level I Trauma Center. Two weeks after the trauma, participants self-reported their experiences with racial discrimination and peritraumatic dissociation. At the six-month follow-up appointment, individuals underwent a clinical assessment of their PTSD symptoms.Results: Results of longitudinal mediation analyses showed that peritraumatic dissociation significantly mediated the effect of racial discrimination on PTSD symptoms, after controlling for age and lifetime trauma exposure. A secondary analysis was conducted to examine the moderating role of gender. Gender was not a significant moderator in the model.Conclusions: Findings show that racial discrimination functions as a stressor that impacts how individuals respond to other traumatic events. The novel results suggest a mechanism that explains the relationship between racial discrimination and PTSD symptoms. These findings highlight the need for community spaces where Black Americans can process racial trauma and reduce the propensity to detach from daily, painful realities. Results also show that clinical intervention post-trauma must consider Black Americans' experiences with racial discrimination.

Peritraumatic dissociation operates as a mechanism through which racial discrimination predicts posttraumatic symptoms in an adult trauma sample.Racial discrimination functions as a stressor that increases the risk for trauma-related symptoms.The lived experiences of Black Americans elicit the use of emotional detachment strategies that may mitigate effects of racial discrimination but increase the risk for peritraumatic dissociation.

The effect of resource loss on depression and peritraumatic distress during the early period of the COVID-19: considering the pandemic-situational and social context.

BACKGROUND: The public experienced loss of resources, including their health and property during the COVID-19 pandemic. The Conservation of Resources (COR) theory is a useful tool to explain the effect of resource loss on mental health. This paper examines the effect of resource loss on depression and peritraumatic distress considering the situational and social context of the COVID-19 pandemic applying COR theory. METHODS: An online survey was conducted for Gyeonggi residents when the second wave of COVID-19 in South Korea declined (5 October to 13 October 2020); 2,548 subjects were included in the hierarchical linear regression analysis. RESULTS: COVID-19 infection-related experiences, resource losses (e.g., financial burden, deterioration of health, and decline of self-esteem), and fear of stigma were related to elevated levels of peritraumatic distress and depression. Risk perception was associated with peritraumatic distress. Reduced income or job loss were related to depression. Social support was a protective factor for mental health. CONCLUSIONS: This study suggests that we need to focus on COVID-19 infection-related experiences and loss of daily resources in order to understand mental health deterioration during the COVID-19 pandemic. Moreover, it is important to monitor the mental health of medically and socially vulnerable groups and those who have lost resources due to the pandemic and to provide them with social support services.

Psychological Well-Being of Cancer Patients before and during the Pandemic: The Impact of COVID-19 Peritraumatic Distress.

BACKGROUND: This study aimed to evaluate the psychological impact of the COVID-19 pandemic on cancer patients. METHODS: Ninety cancer patients undergoing chemotherapy with antiblastics were recruited from a tertiary medical center and completed a battery of standardized questionnaires to assess anxiety, depression, peritraumatic stress, and quality of life before and during the pandemic. RESULTS: Quality of life worsened significantly during the pandemic compared with the pre-pandemic period. Anxiety and depression levels also increased significantly during the pandemic. COVID-19 peritraumatic distress significantly predicted lower quality-of-life scores during the pandemic. CONCLUSIONS: COVID-19 distress affected the overall quality of life of patients who already had lower levels of quality of life before the pandemic and who had advanced cancers. Cancer patients must receive adequate support from psychiatrists and psychologists to mitigate the psychological distress related to the pandemic.

The Victim-Perpetrator Relationship and Peritraumatic Schemas as a Result of Sexual Trauma.

The development of posttraumatic stress symptoms (PTSS) due to sexual trauma is complex. Various mechanisms have been studied to explain the relationship between sexual trauma and PTSS. Other studies have looked at the impact of the victim-perpetrator relationship on the relationship between sexual trauma and PTSS with mixed results. Lacking from the literature is the possible mediating effect of peritraumatic schemas for the relationship between sexual trauma and PTSS. Additionally, the impact of the type of victim-perpetrator relationship may have on the development of peritraumatic schemas has also been unaddressed. This study seeks to close the gap in the literature by asking if peritraumatic schemas mediate the relationship between sexual trauma, specifically attempted and completed rape, and PTSS. The moderating role of the victim-perpetrator relationship on the association between sexual trauma and peritraumatic schemas was also examined. Using a college student sample that had endorsed experiencing at least one sexual trauma in their life, this study examined path analysis model explaining the mediating effects of peritraumatic schemas and the moderating effects of the victim-perpetrator relationship. Results indicated that peritraumatic schemas partially mediated the relationship between attempted rape and PTSS when controlling for completed rape. This effect was not found for the relationship between completed rape and PTSS when controlling for attempted rape. The interaction between attempted rape and the acquaintance perpetrator relationship was significant, indicating that peritraumatic schemas increased more severely for those that experienced attempted rape by an acquaintance. Recognizing that PTSS partially results from the peritraumatic schemas experienced, which are impacted by the victim-perpetrator relationship, helps increase understanding of the experience of attempted rape.

Peritraumatic distress across the lifespan: Clinical implications of age differences during the COVID-19 pandemic.

The Peritraumatic Distress Inventory (PDI) is a well-known self-report questionnaire indexing the distress experienced during and shortly after a most stressful or traumatic event. Although sociodemographic factors contributing to peritraumatic distress have been previously investigated, no research has examined the nature and severity of peritraumatic distress reactions in a non-clinical, community sample as a function of age. An international sample of 5621 adult participants were grouped according the World Health Organization's age stratification protocol. Mean scores and item endorsement on the PDI were compared across groups with respect to their worst experience of the COVID-19 pandemic. A significant between-group difference was found, F(55,615) = 30.74, p < 0.001, n2  = 0.027 whereby participants aged 18-39 years old reported the highest levels of peritraumatic distress. This group also endorsed a higher proportion of items on the PDI's two main factors (emotional distress and physical reactions), and were more likely to endorse feelings of helplessness, than older participants. It appears that severity of peritraumatic distress during the pandemic has affected younger people the most. Results are discussed in light of clinical implications.

Dissociation as a Distinct Peritraumatic Coping Response: A Preliminary Analysis.

Research examining physiological responses to trauma cues in PTSD has identified a subset of "nonresponders" showing suppressed physiological reactivity. The defense cascade model posits that individuals respond to stressors by progressing through a series of defensive reactions, with nonresponders having advanced to a shutdown response. It remains unclear whether dissociation is at the end of a continuum of passive behavior, indicating full shutdown, or if it comprises a distinct response. The present study aimed to address this uncertainty, using EFA to compare a two-factor (active, passive) and three-factor (active, passive, dissociative) model of defensive responding. Eighty-nine female physical and sexual assault survivors reported their peritraumatic reactions within 1 month of their assault, which were entered into the EFA. The three-factor model was superior, suggesting dissociation is a distinct category of peritraumatic coping. Peritraumatic use of both passive and dissociative coping strategies were each significantly associated with ongoing use of passive coping and increased PTSD symptoms 1-month posttrauma; surprisingly, the use of passive peritraumatic coping strategies was a better indicator than peritraumatic dissociation. The inclusion of depression as a covariate removed the association of passive (but not dissociative) coping with PTSD symptom severity. Active coping use was not significantly associated with any outcome, suggesting that the presence of shutdown responses is more informative than the presence or absence of any active coping. These findings highlight the importance of differentiating peritraumatic coping responses and the need for increased attention to the comparatively neglected topic of passive coping.

Muito além do trauma: uma investigação sobre o papel das reações peritraumáticas sobre o transtorno de estresse pós-traumático / Beyond the trauma: an investigation of the role of peritraumatic reactions on posttraumatic stress disorder

O Transtorno de Estresse Pós-Traumático (TEPT) é uma condição debilitante que impacta significativamente a qualidade de vida dos seus portadores. Dentre vários fatores de risco para o TEPT, as reações peritraumáticas (RP), como a imobilidade tônica peritraumática (ITP), dissociação (DP) e reações físicas de pânico (RFP), estão entre as mais investigadas. No entanto, a maioria dos estudos avaliou essas RP separadamente, e o elo entre elas e o TEPT ainda não foi bem compreendido. Portanto, essa tese teve como objetivos: (i) estimar simultaneamente o efeito das três RP sobre o TEPT utilizando um instrumento validado; e (ii) avaliar se há efeito indireto da ITP sobre o TEPT mediado pelo sentimento de culpa/vergonha. Utilizamos modelagem de equações estruturais para analisar dados de 3211 participantes do Rio de Janeiro e de São Paulo. Tratamos as RP como variáveis latentes, selecionando desconfundidores específicos para cada reação. Nossas exposições foram as RP, sendo TEPT o desfecho. Calculamos odds ratios e intervalos de confiança de 95%. Utilizamos o Bayesian Information Criterion para comparar o ajuste de modelos não aninhados. Quando analisadas separadamente, todas as RP alcançaram significância estatística. No entanto, apenas DP (ORDP=1,8; IC95%:1,3-2,4) e RFP (ORRFP=2,5; IC95%:1,8-3,4) permaneceram estatisticamente significativas quando incluímos as três reações em um modelo com seus respectivos desconfundidores e correlações entre elas. Os resultados sugeriram um possível efeito da ITP sobre o TEPT (ORITP=1,4; IC95%:1,0-1,9). As interações entre as RP não foram estatisticamente significativas. Ao investigarmos o sentimento de culpa/vergonha como mediador entre ITP e TEPT, o efeito indireto alcançou apenas significância estatística limítrofe (ORITP(TNIE)=1,1; IC95%:1,0-1,2). Os efeitos direto (ORITP(PNDE)=1,3; IC95%: 0,8-1,8) e total (ORITP(TE)=1,4; IC95%:0,9-1,9) para ITP perderam significância quando todas as RP, seus desconfundidores e correlações entre elas fizeram parte do mesmo modelo. As demais RP, no entanto, permaneceram estatisticamente significativas (ORDP=1,7; IC95%:1,3-2,3 e ORRFP=2,5; IC95%:1,8-3,4). Nossos resultados mostraram que a DP e as RFP aumentaram o risco de TEPT mesmo quando consideradas em conjunto. A ITP pode ter efeito sobre o risco de TEPT, mas esse achado deve ser interpretado com cautela devido a significância limítrofe dessa RP em nosso modelo final. Também não identificamos uma mediação significativa entre ITP e TEPT pelos sentimentos de culpa/vergonha. Contudo, a significância limítrofe encontrada para o efeito indireto demanda investigações adicionais. Nossos achados reforçam a ideia de que as reações peritraumáticas devem ser analisadas e compreendidas como ocorrências simultâneas. Também seria oportuno que estudos envolvendo culpa/vergonha, ITP e TEPT focalizassem traumas caracterizados por aprisionamento e impossibilidade de escapar, dado que estas experiências são apontadas como mais susceptíveis para desencadear a ITP.

Posttraumatic stress disorder (PTSD) is a debilitating condition that greatly impacts quality of life. Among several PTSD risk factors, peritraumatic reactions (PR) such as peritraumatic tonic immobility (PTI), dissociation (PD) and physical panic reactions (PPR) are some of the most investigated. However, several studies have assessed these PR separately, and the pathway connecting them to PTSD is not well understood. Therefore, this thesis aimed to: (i) simultaneously estimate the effect of the three PR on PTSD using a validated instrument; and (ii) assess if there is an indirect effect of PTI on PTSD mediated by feelings of guilt/shame. We used structural equation modelling to analyse data from 3211 participants from Rio de Janeiro and São Paulo. We treated the PR as latent variables and selected specific confounders for each reaction. Our exposures were the PR, and PTSD was the outcome. We calculated odds ratios and 95% confidence intervals for each analysis. We also employed the Bayesian Information Criterion to compare the goodness of fit between non-nested models. Separately, all PR achieved statistically significant results. However, only PD (ORPD=1.8; 95%CI:1.3-2.4) and PPR (ORPPR=2.5; 95%CI:1.8-3.4) remained statistically significant when all three were included in a model with their respective confounders and correlations among all PR. Our findings suggested a possible effect of PTI on PTSD (ORPTI=1.4; 95%CI:1.0-1.9). Interactions between the PR were not statistically significant. When we investigated feelings of guilt/shame as the mediator between PTI and PTSD, the indirect effect achieved a borderline statistical significance (ORPTI(TNIE)=1.1; 95%CI:1.0-1.2). Direct (ORPTI(PNDE)=1.3; 95%CI:0.8-1.8) and total (ORPTI(TE)=1.4; 95%CI:0.9-1.9) effects lost their significance when all PR, their confounders and correlations were included in the same model. The other PR remained statistically significant (ORPD=1.7; 95%CI:1.3-2.3 and ORPPR=2.5; 95%CI:1.8-3.4). Our findings showed PD and PPR to increase the risk of PTSD even when considered in tandem. PTI could have an effect on PTSD, but this must be considered cautiously, as this PR only reached borderline significance in our final model. Feelings of guilt/shame did not significantly mediate PTI's effect on PTSD. However, a borderline statistical significance in the indirect effects warrants further investigation. Our findings reinforce the hypothesis that peritraumatic reactions should be analysed and understood as simultaneous occurrences, not as separate entities. It would also be appropriate for studies concerning guilt/shame, PTI and PTSD to focus on traumas characterized by imprisonment and feelings of inescapability, given that these experiences are allegedly more likely to trigger PTI.

Peritraumatic distress in Southern Indian inhabitants during second wave COVID-19 pandemic: A community-level survey.

Introduction: As coronavirus disease 2019 (COVID-19) is a new disease which has ruining and dismantling the harmony of people internationally, its development and spread, creates turmoil, nervousness and dread among worldwide. Aim: To evaluate seriousness of peritraumatic problems among southern Indian inhabitants during the COVID-19 pandemic. Methodology: A referral sampling technique was continued until a sufficient sample size was reached, while this self-administered survey catches insights about depression, fears, psychological change, evasion cognitive change, and collectively quantifies the stress on a scale of 0-60. Expressive factual examinations were utilized to sum up clear cut information and inferential measurable investigations included Chi-square tests and Pearson's correlations were done. Results: The study included only those participants who understood English and had access to the internet. Inconsequential outcomes were found among gender in which both male and female members frequently showed apprehension and nervousness about COVID-19. 44.8% tried not to watch the news on COVID-19 as they were excessively frightened and make frenzy to family members. 90.9% of participants with lower education levels were more stressed over the thought of getting COVID-19 when showing manifestations related with the novel corona virus, which was statistically significant. Conclusion: The current assessment shows that almost all the study participants have felt restless, uncomfortable and terrified of watching the news whilst stressed over appearances related with COVID-19 due to their greater access to information.

"Not understanding but feeling guilty at the same time": The peritraumatic responses of CSA survivors from the Muslim Arab community in Israel.

BACKGROUND: Studies on child sexual abuse (CSA) have greatly contributed to theoretical and empirical developments, advancing policy and practice. However, studies on CSA in closed societies are still scarce. OBJECTIVE: The current study focuses on CSA in the Muslim Arab community in Israel while delving into the peritraumatic responses of survivors to CSA. PARTICIPANTS AND SETTING: Twenty-eight Muslim Arab survivors of CSA provided written testimonies for an independent inquiry. METHODS: The exploration of the Muslim Arab survivors' peritraumatic responses to CSA, according to their testimonies, was guided by an inductive thematic analysis and Braun and Clarke's (2006) six steps of analysis. RESULTS: The results indicated that, as most of the abusive incidents were committed by an extended family member, the survivors experienced an inability to understand what had happened to them while simultaneously feeling guilt and self-blame. Furthermore, the survivors discussed feeling trapped by all of the systems and social expectations in their lives, leaving them feeling extremely lonely and with the understanding that seeking help and disclosing the abuse was not relevant for them. CONCLUSION: The discussion addresses the developments in the research on peritraumatic responses that require further examination. This includes top-down processes that might explain survivors' peritraumatic responses, which are not merely instinctual. In addition, when perpetrators are family members, survivors are expected to stay in contact with them, which demands enormous resources and survival strategies from the survivors.

Prevalence and prediction of PTSD and depression in mothers of children surviving a motor vehicle crash.

Introduction: Few studies have examined the psychopathological consequences for parents of children who were survivors of a motor vehicle crash (MVC). This study assessed the impact of dissociation and peritraumatic distress on the severity of PTSD and post-traumatic major depressive episode (MDE) symptoms in mothers during the first years after the MVC and the role that cortisol response might play in this association. Methods: 125 mothers were included. Peritraumatic distress and dissociation were assessed. Morning salivary cortisol was tested at the baseline. Participants were assessed for a probable diagnosis of PTSD and MDE at 5 weeks, 6 months and 12 months. Results: At 5 weeks, 12 (13.6%) mothers exhibited probable PTSD. During the first year, the PCL score was higher when the (i) Peritraumatic Distress Inventory (PDI) score increased and (ii) the Peritraumatic Dissociation Experience Questionnaire (PDEQ) score increased. Cortisol levels were lower when the PDI score increased. Conclusion: This is the first study to assess the mothers of MVC survivors for one year following the trauma. We confirm that peritraumatic responses are useful for predicting the severity of PTSD symptoms. These results could encourage the implementation of follow-up programmes not only for survivors but also for their mothers. HIGHLIGHTS Mothers of children involved in motor vehicle accident are at risk for developing PTSD.Peritraumatic responses (distress and dissociation) are associated to the severity of PTSD symptoms.Low salivary cortisol levels were associated with high peritraumatic distress.

Antecedentes: Pocos estudios han examinado las consecuencias psicopatológicas para los padres de niños que fueron sobrevivientes de un accidente automovilístico (MVC, por sus siglas en inglés).Objetivo: Este estudio evaluó el impacto de la disociación y la angustia peritraumática en la gravedad del TEPT y los síntomas del episodio depresivo mayor (EDM) postraumático en las madres durante los primeros años después del MVC y el papel que podría desempeñar la respuesta del cortisol en esta asociación.Métodos: Se incluyeron 125 madres. Se evaluó la angustia peritraumática y la disociación. El cortisol salival matutino se analizó al inicio del estudio. Los participantes fueron evaluados para un diagnóstico probable de TEPT y EDM a las 5 semanas, 6 meses y 12 meses.Resultados: A las 5 semanas, 12 (13,6%) madres exhibieron TEPT probable. Durante el primer año, la puntuación PCL (lista de chequeo para TEPT) fue mayor cuando i) aumentó la puntuación del Inventario de angustia peritraumática (PDI, por sus siglas en inglés) y ii) aumentó la puntuación del Cuestionario de experiencias de disociación peritraumática (PDEQ, por sus siglas en inglés). Los niveles de cortisol fueron más bajos cuando aumentó la puntuación PDI.Conclusión: Este es el primer estudio que evalúa a las madres de sobrevivientes de MVC un año después del trauma. Confirmamos que las respuestas peritraumáticas son útiles para predecir la gravedad de los síntomas del TEPT. Estos resultados podrían incentivar la implementación de programas de seguimiento no solo para las sobrevivientes sino también para sus madres.
