Families With Violence Exposure and the Intergenerational Transmission of Somatization

A biomarker of brain arousal mediates the intergenerational link between maternal and child post-traumatic stress disorder

This study examined whether there is a biological basis in the child's resting brain activity for the intergenerational link between maternal interpersonal violence-related posttraumatic stress disorder (IPV-PTSD) and child subclinical symptoms. We used high-density EEG recordings to investigate the resting brain activity in a sample of 57 children, 34 from mothers with IPV-PTSD, and 23 from mothers without PTSD. These children were part of a prospective, longitudinal study focusing on the offspring of mothers with and without IPV-PTSD, reporting how the severity of a mother's IPV-PTSD can impact her child's emotional regulation and risk for developing mental illness. However, we had not yet looked into potential EEG biomarkers during resting state that might mediate and/or moderate effects of maternal IPV-PTSD severity on child mental health, and in particular the risk for PTSD. The alpha band spectral power as well as the aperiodic exponent of the power spectrum (PLE; power-law exponent) were examined as mediators of maternal IPV-PTSD and child PTSD. While there was no difference in alpha spectral power between the two groups, PLE was significantly reduced in children of mothers with IPV-PTSD compared to control children, indicating cortical hyper-arousal. Interestingly, child PLE was negatively correlated with the severity of maternal IPV-PTSD, suggesting an intergenerational interaction. This interpretation was reinforced by a negative correlation between child PLE and child PTSD symptoms. Finally, causal analyses using structural equation modelling indicated that child PLE mediated the relationship between maternal PTSD severity and child PTSD. Our observations suggest that maternal IPV-PTSD has an intergenerational impact on the child neurobehavioral development through a correlated abnormal marker of brain arousal (i.e. child PLE). These findings are potentially relevant to psychotherapy research and to the development of more effective psycho-neurobehavioral therapies (i.e. neurofeedback) among affected individuals.

The Impact of Maternal Interpersonal Violent Trauma and Related Psychopathology on Child Outcomes and Intergenerational Transmission

PURPOSE OF REVIEW

This review aims to outline some consequences that maternal history of trauma with and without related psychopathology, such as posttraumatic stress symptoms (PTSS), can have on their children's development and functioning. It then addresses mechanisms through which intergenerational transmission of interpersonal violence (IPV) and related psychopathology may occur.

RECENT FINDINGS

Findings include the effects of maternal IPV experience and related psychopathology on child social-emotional and biologically-based outcomes. This includes increased developmental disturbances and child psychopathology, as well as physiological factors. Secondly, the review focuses on psychobiological mechanisms by which maternal experience of IPV and related psychopathology likely trigger intergenerational effects. Maternal IPV and related psychopathology can have a negative impact on several areas of their child's life including development, interactive behavior, psychopathology, and physiology. This transmission may partially be due to fetal and perinatal processes, genetic and epigenetic effects, and interactions with their parents.

Somatic and Posttraumatic Stress Symptoms in Children and Adolescents in France

Importance

Somatic symptoms are a major concern among the pediatric population because of frequency and burden. The association between adverse childhood experiences and somatic symptoms in adults is well established but less is known concerning somatic symptoms in young people.

Objective

To explore the frequency and intensity of somatic symptoms in children and adolescents exposed to traumatic events.

Design, Setting, and Participants

This cross-sectional study was conducted from January 1 to December 31, 2021, at the Nice Pediatric Psychotrauma Referral Center in Nice, France. Participants included pediatric outpatients, aged 7 to 17 years, who were referred to the center. Statistical analysis was performed in January 2022.

Exposure

All participants experienced at least 1 traumatic event during life.

Main Outcome and Measure

Somatic and posttraumatic stress symptoms were assessed using the Patient Health Questionnaire-13 (PHQ-13) and Child PTSD Checklist (CPC). Posttraumatic stress disorder (PTSD) and non-PTSD groups were defined based on CPC symptoms severity score. In the hypothesized association between somatic symptoms and posttraumatic stress symptoms (PTSS), PTSD and non-PTSD groups were compared, correlations between PTSS and severity of CPC were analyzed, and a regression model was performed.

Results

There were 363 participants included (mean [SD] age, 13.58 [0.25] years; 174 [47.9%] female, 189 [52.1%] male). Compared with the non-PTSD group, the PTSD group presented with a higher mean (SD) number of somatic symptoms (7.0 [2.5] vs 4.0 [2.5] symptoms; t360 = 11.7; P < .001), and higher mean (SD) intensity (10.4 [4.6] vs 4.8 [3.7] points; t360 = 12.6; P < .001). Most of the explored somatic symptoms positively correlated with the intensity of PTSS and their functional alterations (eg, PTSS intensity correlated with stomach pain symptoms [r = .30; P < .001]; and with headaches symptoms [r = .44; P < .001]). In the regression model, the combination of migraines, palpitation, nausea, tiredness, and sleep disorders explained 6.5% of the variance in the PTSD group. (F1,341 = 22.651; P < .001).

Conclusions and Relevance

In this cross-sectional study, somatic symptoms were positively correlated with PTSS both in frequency and intensity among youths. These results suggest that the systematic screening for somatic symptoms in youths with traumatic exposure should be a routine evaluation procedure.

Role of history of traumatic life experiences in current psychosomatic manifestations

OBJECTIVES

Although the relationship between traumatic experiences (TEs) and psychosomatic manifestations (pain, somatization, somatosensory amplification [SSA], and alexithymia) has been widely described, very few studies have investigated how these variables correlate with each other and with a history of TEs. The aim of this study was to investigate whether and how current psychosomatic manifestations are correlated with major and minor adult- and childhood TEs.

METHODS

One hundred and forty-six patients (91 with pain) from the Pisa Gift Institute for Integrative Medicine Psychosomatics Lab., Italy, were assessed for pain, history of TEs (divided into major and minor based on whether or not they meet the DSM-5 Criterion A for post-traumatic stress disorder), alexithymia, somatization, and SSA.

RESULTS

TEs were positively correlated with age, the sensorial dimension and intensity of pain, somatization, psychopathology index, SSA, and alexithymia. Using the somatization score (controlled for age) as a covariate, the previous correlations between psychosomatic dimensions and TEs lost their statistical significance: SSA (total TEs: from r = 0.30, p = 0.000 to r = -0.04, p = 0.652); alexithymia (total TEs: from r = 0.28, p = 0.001 to r = 0.04, p = 0.663); sensorial dimension of pain (total TEs: from r = 0.30, p = 0.015 to r = 0.12, p = 0.373); and pain intensity (total TEs: from r = 0.38, p = 0.004 to r = -0.15, p = 0.317). Interestingly, the tendency to report more intense pain was mainly predicted by minor TEs in childhood (β = 0.28; p = 0.030).

CONCLUSIONS

The number of lifetime TEs is positively correlated with the sensorial dimension and intensity of pain but not its affective and cognitive dimensions. However, the former relationship depends on the presence of somatization. The intensity of pain is associated with minor rather than major TEs, especially when they occur in childhood.

Attachment Anxiety and Dissociation Mediate Associations Between Polytrauma and Somatization in Kenyan Adolescents

The experience of several potentially traumatic events (PTE) is a risk factor for higher somatization symptoms severity among adolescents. Attachment orientations and dissociation may influence the link between exposure to PTE and somatization symptoms severity. We analyzed the associations between direct exposure to PTE and somatization symptoms in Kenyan adolescents and explored the mediating role of attachment orientations and dissociation symptoms in the associations between direct exposure to PTE with somatization symptoms severity. A sample of 475 Kenyan adolescents completed validated self-report questionnaires. Serial multiple mediation models were tested by conducting a structural equation modeling employing Preacher and Hayes' procedures (2008). Attachment anxiety and dissociation symptoms mediate the association between direct exposure to traumatic events and somatization symptoms. Higher exposure to traumatic events was significantly associated with higher attachment anxiety levels, which was associated with higher levels of dissociation symptoms, which was then associated with higher somatization symptoms severity. High levels of attachment anxiety and dissociation might aggravate somatization symptoms differently according to sex, which might be seen as a psychological distress mechanism subsequent to exposure to multiple PTE in African adolescents.

Does Childhood Experience of Interparental Abuse Shape Women's Attitude Toward Intimate Partner Violence in Their Adult Life? Evidence From 31 Developing Countries

A significant amount of literature exists on the lasting effects of interparental abuse on children's psychological health as adults. However, evidence on how children's childhood experience of interparental violence shapes their attitude toward partner violence in adult intimate relationships is limited. Given the existing evidence that women's acceptance of partner violence as a social norm increases the risk of partner violence, we analyzed the effect of girls' witnessing interparental abuse (where a father is a perpetrator) on their attitude toward partner violence in their intimate relationships as adults. We used data from the Demographic and Health Surveys for 31 low and middle-income countries in Asia and Africa. Aggregating information about women's attitudes toward partner violence into a binary "intimate partner violence acceptance" variable, we found that a woman who witnessed her father beat her mother was 1.62 times more likely to justify partner violence than a woman who did not experience such interparental abuse (adjusted odds ratio [AOR] = 1.62, 95% CI [1.57, 1.66], p < .001). Additionally, using individual components of acceptance as response variables, we found that a woman who witnessed interparental abuse was significantly more likely to justify partner violence if she went out without telling her husband (OR = 1.49, 95% CI [1.45, 1.54], p < .001), neglected children (OR = 1.53, 95% CI [1.49, 1.58], p < .001), argued with the husband (OR = 1.49, 95% CI [1.45, 1.53], p < .001), refused sex with the husband (OR = 1.35, 95% CI [1.31, 1.39], p < .001), or burned food (OR = 1.36, 95% CI [1.31, 1.41], p < .001). This study highlights the need to put in place children-specific social policies to limit the intergenerational transmission of the adverse effects of intimate partner violence.

"No matter what, we just work with the trauma…": Mental Health Therapists' Care of Diverse Sexual and Gender Identity Citizens in Cambodia

The convergence of trauma symptomatology, mental health symptoms, family and social difficulties, and intersectionality of diverse sexual and gender minority (SGM) individual issues is complex, multi-faceted, and challenging for the individuals in Cambodia who suffer them and for the therapists in Cambodia who meet individuals in treatment. We documented and analyzed the perspectives of mental health therapists in the context of a randomized control trial (RCT) intervention within the Mekong Project in Cambodia. The research questions explored perceptions of therapists' care of mental health clients, therapist wellbeing, and experiences of navigating within a research environment in which SGM citizens with mental health concerns receive treatment. The larger study enrolled 150 Cambodian adults, among which 69 identified as SGM. Three key patterns emerged across our interpretations. Clients seek help when symptoms interfere with daily life, therapists care for clients and themselves, and integrated research and practice is integral yet sometimes paradoxical. Therapists did not identify differences in terms of how they work with SGM clients compared with non-SGM clients. Future studies are warranted to examine a reciprocal academic-research partnership in which we examine therapists' work alongside rural community members, evaluate the process of embedding and fortifying peer supports within educational systems, and study the wisdom of traditional and Buddhist healers to address the discrimination and violence that citizens who identify as SGM disproportionately suffer.
