Peritraumatic dissociation predicts posttraumatic stress disorder symptoms via dysfunctional trauma-related memory among war-affected children

Peri-Traumatic Dissociation and Tonic Immobility as Severity Predictors of Posttraumatic Stress Disorder After Rape

Some individuals show abnormal reactions to extreme fear and life-threatening situations, including tonic immobility (TI) and peri-traumatic dissociation (PTD). We aimed to investigate the association of TI and PTD with posttraumatic stress disorder (PTSD) in women who experienced sexual violence and the risk factors for PTD occurrence. We compared PTSD severity in 86 young adult women with PTSD after a sexual violence exposure grouped according to the presence of PTD and TI. In addition, we investigated whether PTD is associated with depression and anxiety symptoms and assessed potential risk factors for PTD reaction. We found a significant positive correlation between PTSD severity and PTD occurrence (R² = .132; p = .001). PTD was also positively correlated with all clusters of PTSD symptoms except the Clinician-Administered PTSD Scale avoidance cluster (p = .058). PTD was strongly correlated with anxiety (R² = .619; p < .001) and depressive symptoms (R² = .547; p < .001). Multiple logistic regression showed that history of physical abuse (odds ratio [OR]: 1.386; p = .011) and sexual abuse (OR: 1.947; p = .004) during childhood were associated with PTD occurrence. Other risk factors for PTD were having less years of study (OR: 0.216; p = .016) and lower income (OR: 7.403; p = .028). TI measures were available for a subsample of 29 women. We found no association between TI and PTSD severity. PTD, but not TI, is significantly associated with more severe PTSD, depressive, and anxiety symptoms. Less-educated women with a history of childhood abuse and a lower income are at risk of PTD occurrence during a sexual violence episode.

Breaking the cycles of violence with narrative exposure: Development and feasibility of NETfacts, a community-based intervention for populations living under continuous threat

BACKGROUND

Interpersonal violence damages mental health and frequently leads to aggressive defence strategies. If survivors are subsequently blamed for the events, both consequences worsen. Stigma flourishes, especially when survivors are silenced so that details of the trauma remain unknown. Breaking the secrecy both at the individual and collective level is key to enable the healing and reconciliation of individuals and communities living under continuous threat.

METHOD

The NETfacts health system is a stepped care model with three components: (1) Narrative Exposure Therapy (NET), an evidence-based trauma therapy that includes survivor testimony (2) NET for Forensic Offender Rehabilitation (FORNET) acknowledges that perpetrators are frequently also victims and assists in reducing aggression and the attraction to violence, and (3) a community intervention disseminating and discussing Facts derived from NET treatment (NETfacts) to challenge the collective avoidance of atrocities and other traumatic material. The intervention was piloted in a community with 497 adult residents in Eastern Democratic Republic of Congo. The willingness of clients to consent to sharing their anonymised testimonies (with a focus on sexual violence survivors and ex-combatants) was investigated, together with other components of feasibility including security and clinical safety, extent of support of respected local authorities and participation rates. As secondary outcomes, clinical and social measures were assessed before and post NETfacts among 200 village residents of whom 160 self-enrolled and 40 had not participated in any form of treatment.

RESULTS

Implementation was feasible with 248 clients from a partner project giving consent to use their testimonies and high support of respected local authorities and participation rates (56% of residents self-enrolled in NETfacts). Immediate beneficial effects were shown for posttraumatic stress and rejection of rape myths among NETfacts participants who experienced multiple traumatic events in their own past. Attitudes towards ex-combatants improved and the perceived lack of social acknowledgement after trauma increased independent from participation. No significant change was observed for depressive symptoms.

CONCLUSION

NETfacts is a feasible and promising approach to challenge the culture of secrecy surrounding trauma, suppression and social exclusion. Long term effectiveness requires further evaluation.

The war next-door-A pilot study on Romanian adolescents' psychological reactions to potentially traumatic experiences generated by the Russian invasion of Ukraine

Introduction

Romania shares the longest UE border with Ukraine, and since the Russian invasion of Ukraine began, many have been involved in helping the refugees. Consequently, children and adolescents might be directly and indirectly exposed to war-related trauma. In the present exploratory research, we investigated Romanian adolescents' potential risk and protective factors related to the psychological outcomes of war exposure. Our cross-sectional study was conducted shortly after February 24th (i.e., the first invasion day).

Methods

The sample included 90 Romanian adolescents aged 11 to 15 (M = 12.90, SD = 1.17), residents in Iași, Romania (i.e., 205,7 km from the Ukrainian border). Participants completed self-reported measures of peritraumatic dissociative experiences, knowledge about the conflict in Ukraine, personal, school, and family implications in volunteering/helping behavior, discussions about the conflict, threat perception (self and perceived parental threat), anxiety, social media engagement, resilience, and moral elevation.

Results

The main findings suggested that participants involved in helping behaviors toward Ukrainian refugees present higher peritraumatic dissociative experiences, anxiety symptoms, and higher moral elevation than boys and participants not involved in these behaviors. Moreover, anxiety symptoms were positively associated with threat perception, peritraumatic dissociation, and social media engagement and negatively related to resilience.

Discussions

Finally, we discuss the implications of our findings concerning their practical utility in managing peritraumatic exposure to war by using interventions designed to increase adolescents' resilience during difficult times.

Psychological Functioning of Adolescents from Violent Families

Objective. The aim of the study was to determine the association of family violence with the functioning of the family system, psychological functioning and development of specific characteristics of the adolescents who grew up in a violent families.

Methods. The study was carried out on a sample of 308 adolescents, aged 15–18, divided in a FV group of adolescents coming from dysfunctional families (n=68) adolescents who grew up inviolent families and were exposed to family violence, which was reported and processed, and a control group (n=240) adolescents from families in which according to the CPRS-R Questionnaire there was not found any form of violence, alcoholism or any other psychosocial pathology. FACES III Scale and Questionnaire for the examination of psychosocial characteristics of the adolescents and family (Revised CPRS-R) were used for measuring dimensions of family functioning, Cybernetic model of personality dimensions (CON-6) for conative functioning of the adolescents, Теst for reasoning images (TRI) for measuring intellectual development and the Scale of Latent Maturity (SLM) for determining the level of psychological maturity. The data were processed by using linear regression analysis.

Results. Family functioning disorders caused by family violence were significantly and highly associated with psychological functioning of the adolescents: concern about family relationships (β =-.968), need for professional help (β =-.873), cooperation with people (β =.523), orientation towards the future (β =.669), latent maturity (β =.618), psychosomatic reactions (β =-.509), dissociative reactions (β =-.591), excused absence from school (β =.618), unexcused absence from school (β =-.824), memory disorders (β =-.541), night fears (β =−722), running away from home (β =-.569), breaking rules and getting punished at school (β =-.569), conflicts with peers (β =−.460). Conative functioning of the adolescents exposed to a violent family environment showed a pathological form of functioning in dissociative, anxiety reactions and social adaptability.

Conclusion. Exposure of adolescents to a violent family environment was associated with changes in psychological functioning, development of specific personality characteristics and risk of developing internalized and externalized symptoms when it came to socialadaptation, anxiety and dissociative reactions. The mediators between family violence and psychological functioning and development of the adolescents was family cohesion and disorders within the marital dyad.

Mental imagery in adolescent PTSD patients after child abuse: a comparison with matched healthy controls

BACKGROUND

Intrusive mental imagery (MI) plays a crucial role in the maintenance of posttraumatic stress disorder (PTSD) in adults. Evidence on the characteristics of MI in adolescents suffering from PTSD is sparse. The aim of this study was to thoroughly assess MI in an adolescent sample suffering from PTSD after the experience of childhood sexual abuse and/or childhood physical abuse (CA).

METHODS

Thirty-two adolescents with a primary diagnosis of PTSD after CA and 32 adolescents without any mental disorder and without a history of CA, matched for age and gender, completed questionnaires assessing the characteristics of negative and positive MI, as well as images of injury and death that lead to positive emotions (ID-images).

RESULTS

The PTSD group reported significantly more frequent, more vivid, more distressing and more strongly autobiographically linked negative MI compared to the control group. Although positive MI was highly present in both groups (PTSD: 65.6%; controls: 71.9%), no significant differences emerged between the two groups regarding the distinct characteristics of positive MI. The frequency of the ID-images did not significantly differ between the two groups (PTSD: 21.9%; controls: 9.4%), although the ID-images were more vivid in the PTSD group.

DISCUSSION

Negative MI appears to be crucial in adolescent PTSD, whilst positive MI are unexpectedly common in both the PTSD and the control group. The role of positive MI as well as that of ID-images remain unclear. Specific interventions for changing negative MI that are tailored to the developmental challenges in adolescents with PTSD should be developed.

TRIAL REGISTRATION

Some of the PTSD patients in this study were also part of a randomized controlled trial on Developmentally adapted Cognitive Processing Therapy (D-CPT). This trial was registered at the German Clinical Trial Registry (GCTR), DRKS00004787 , 18 March 2013.

Human (in)security and psychological well-being in Palestinian children living amidst military violence: A qualitative participatory research using interactive maps

BACKGROUND

Research has widely evidenced the effects of war and political violence on the functioning of children, with a great accord in diagnosing children's psychological burdens related to their exposure to violence. Yet, within this literature, the influence of the chronic sense of insecurity on their psychological functioning during and after hostilities remains unexplored.

METHODS

The present study aimed at exploring interrelated relationships between the perceived insecurity and the children's psychological well-being and their adjustment to trauma. Based on drawings and walk-along interviews with 75 Palestinian children, residents of both the West Bank and Gaza Strip, we offer an analysis of human security-related risks and protective factors that contribute to either promoting or undermining the child's psychological functioning in a context characterized by chronic instability and political violence.

RESULTS

A complex network of sources of security and insecurity emerged from the narratives depicting an ecological portrait encompassing the determinants of children's mental health and psychological functioning. The TCA led to the identification of eight main themes: school and associativism; social relations and house as a source of security/insecurity; military occupation as a source of insecurity; national and political identity as a source of safety; mosque and spirituality as a source of safety/unsafety; environment as a source of security/insecurity; and mental health.

DISCUSSION

An approach encompassing human security as an explicative model can help in exhaustively portraying the complexity of the Palestinian children's suffering and their competence in adjusting to their traumatic reality. The study draws attention to social, political, environmental and economic determinants of children psychological well-being.

Children's Reactions to War, Armed Conflict and Displacement: Resilience in a Social Climate of Support

PURPOSE OF REVIEW

The aim of this review was to unravel recent evidence for children's reactions to war and armed conflict focusing on resilience factors mitigating adverse psychological and psychiatric consequences.

RECENT FINDINGS

Three categories of mitigating resilience factors emerged from the literature - personal, family, and community factors. In addition, a unifying model of moderating resilience factors emerged, proposing a higher-tier environmental dimension conceptualized here as social climate of support. Wars and armed conflict affect children both by direct exposure to threats, and by disruption of the social fabric supporting development. The notion of producing a climate of social support can direct policy toward service provision and resilience-based programs that both build individual capacities and encompass development of the resources of families, schools, community, and societal structures supportive of children's adjustment and wellbeing. Future research should shift toward systems thinking within a socio-ecological nesting of individual, familial, community, and societal systems.

Validation of the Italian version of the peritraumatic distress inventory: validity, reliability and factor analysis in a sample of healthcare workers

Background: Peritraumatic distress as assessed by the Peritraumatic Distress Inventory (PDI), has been consistently shown to predict the development of Posttraumatic Stress Disorder (PTSD) after the exposure to a potentially traumatizing event. Objective: The present study aims to validate the Italian version of the PDI in a sample of Healthcare Workers (HCWs) exposed to COVID-19 related potentially traumatizing events. Method: N = 265 HCWs who repeatedly experienced the deaths of patients during COVID-19 emergency in Italy, were enrolled from the Azienda Ospedaliero-Universitaria Pisana (Pisa, Italy). They completed the PDI, Impact Event Scale - revised (IES-R) and the reactions to losses or upsetting events Trauma and Loss Spectrum - Self Report (TALS-SR) domain. Results: Internal consistency was good with a Cronbach's alpha coefficient was .874. The PDI correlated strongly with measures that was conceptually close (TALS-SR reactions to losses or upsetting events domain; r = .723, p < .001). Participants who scored above the cut-off for PTSD reported significantly higher PDI scores than those who did not (6.47 ± 5.25 vs. 19.11 ± 8.291, p < 0.001). The one-month test-retest reliability (n = 21) was excellent (ICC = .997). Finally, factor analyses revealed that the PDI exhibited a single-factor structure. Conclusions: the Italian version of the PDI showed good psychometric proprieties and may be used to detect those at risk for developing PTSD.

NETfacts: a community intervention integrating trauma treatment at the individual and collective level

The aim of this article is to present a research-based rationale for NETfacts, a newly developed integrated approach at the individual and the community level in order to mitigate the mental and social sequelae of war and crisis. To this end, we provide a selective review of relevant literature from neuroscience, clinical psychology, and social science. In psychotraumatology, individual avoidance describes the effort to prevent exposure to trauma reminders. Among patients with post-traumatic stress disorder (PTSD), this becomes pathological, exacerbating distress and preventing recovery. This silence resonates in traumatized communities and consequently taboo builds - ultimately to the advantage of the perpetrators. The resulting collective avoidance leads to a fragmented collective memory about trauma or human rights violations in the community so that a shared account of the group's history becomes impossible. The deficient collective memory promotes ambiguous truths and anxiety, enabling a reactive construction of safety based on selective information that leads to an endorsement of extreme opinions. Ongoing insecurity, violence and crime lead to increasing anxiety and fear. The self-interest of the perpetrators and the abnormal behaviour of survivors leads to an escalation in stigma and social exclusion resulting in the prevention or limitation of community exposure to traumatic material, i.e., to reduce tension and protect the construction of safety. The exposure to and recognition of traumatic facts subject to avoidance is key to a coherent collective memory and sense of communion, and to prevent further cycles of violence. The NETfacts health system combines individual and community-based intervention to treat the structure of memory at both the individual and collective levels.

The effects of trauma on brain and body: A unifying role for the midbrain periaqueductal gray

Post-traumatic stress disorder (PTSD), a diagnosis that may follow the experience of trauma, has multiple symptomatic phenotypes. Generally, individuals with PTSD display symptoms of hyperarousal and of hyperemotionality in the presence of fearful stimuli. A subset of individuals with PTSD; however, elicit dissociative symptomatology (i.e., depersonalization, derealization) in the wake of a perceived threat. This pattern of response characterizes the dissociative subtype of the disorder, which is often associated with emotional numbing and hypoarousal. Both symptomatic phenotypes exhibit attentional threat biases, where threat stimuli are processed preferentially leading to a hypervigilant state that is thought to promote defensive behaviors during threat processing. Accordingly, PTSD and its dissociative subtype are thought to differ in their proclivity to elicit active (i.e., fight, flight) versus passive (i.e., tonic immobility, emotional shutdown) defensive responses, which are characterized by the increased and the decreased expression of the sympathetic nervous system, respectively. Moreover, active and passive defenses are accompanied by primarily endocannabinoid- and opioid-mediated analgesics, respectively. Through critical review of the literature, we apply the defense cascade model to better understand the pathological presentation of defensive responses in PTSD with a focus on the functioning of lower-level midbrain and extended brainstem systems.
