Psychobiological Consequences of Childhood Sexual Abuse: Current Knowledge and Clinical Implications

Childhood abuse and neglect are differentially related to perceived discrimination and structural change in empathy-related circuitry

Behavioral studies indicate that adverse childhood experiences (ACE) are associated with altered empathic responding, but the neural mechanisms underlying this relationship remain unclear. Given the significance of empathy in contexts marred by historical conflict and systemic inequality, work on these mechanisms is particularly important in such contexts. The current study extends previous work by (1) examining associations of different dimensions of ACE with volumetric change in empathy-related circuitry, (2) distinguishing between trait and state empathy, and (3) including perceived discrimination as an additional psychosocial stressor. Thirty-nine healthy South African adults from the general population (Mage = 40.6 years) underwent 3 T MRI. FreeSurfer v6.0 was used to extract predefined volumes subserving empathy. Results showed that childhood abuse and perceived discrimination were associated with reduced state empathic concern, whereas childhood neglect was associated with reduced trait cognitive empathy. Childhood abuse was furthermore associated with volumetric increases in frontolimbic (hippocampus, anterior cingulate cortex (ACC)) and neocortical (superior frontal and temporal) regions subserving affective and cognitive empathy, and uniquely mediated the relationship between ACC volume and perceived discrimination. The association of ACE with altered empathic responding may thus be underpinned by specific circuitry reflective of adversity type, with childhood abuse contributing to heightened responsivity to socioemotional cues.

Resilience amid Adversity: A Qualitative Narrative Study of Childhood Sexual Abuse Among Bangladeshi Transgender Individuals

Childhood sexual abuse (CSA) is a prevalent form of violence against children, associated with profound negative impacts on survivors' health and well-being. In Bangladesh, sociocultural and economic barriers hinder CSA prevention and intervention, particularly for vulnerable populations such as transgender individuals. This study explores the experiences of CSA among Bangladeshi transgender individuals, focusing on their coping mechanisms and resilience-building strategies. A qualitative narrative approach was employed, using life story-telling interviews with four transgender CSA survivors, and data were analyzed thematically. The findings reveal significant challenges, including social exclusion, humiliation, and lack of family support. Participants reported experiencing physical injuries, mental trauma, and loss of trust due to CSA, while the conservative nature of Bangladeshi society often prevented them from disclosing their abuse or seeking healthcare. These barriers exacerbate health inequalities among gender-minority children. Despite these adversities, participants described engaging in resilience-building strategies such as self-care, personal development, advocacy, and efforts to derive meaning from their experiences, while highlighting the perceived importance of family support. This study provides insights into the unique experiences of transgender CSA survivors in Bangladesh and calls for efforts towards gender-inclusive education, mental health support, and further research to address CSA-related adversity, encourage disclosure, and promote health equity for gender-minority groups.

Examining the burden of mental disorders in Jordan: an ecological study over three decades

BACKGROUND

Mental disorders are a major public health issue, causing 4.9% of global disability-adjusted life years (DALYs). In Jordan, factors like regional conflicts, economic changes, and population growth contribute to this burden. This study examines the trends and risk factors of mental disorders in Jordan from 1990 to 2021 using Global Burden of Disease (GBD) data.

METHODS

We analyzed prevalence, deaths, and DALYs of mental disorders from the GBD 2021 dataset, reporting both all-age numbers and age-standardized rates. Key risk factors, including behavioral risks, bullying, childhood sexual abuse, and substance use, were assessed.

RESULTS

Mental disorder cases in Jordan rose by 279.8%, from 514,234 in 1990 to 1,953,087 in 2021. Anxiety and depression were the most common in 2021. All-age DALYs increased by 649.6%, while age-standardized DALY rates showed a slight 4.3% rise. Females had higher mental disorder prevalence and DALY rates, while males had higher substance use disorder rates. Behavioral risks, bullying, and childhood sexual abuse were major contributors.

CONCLUSION

The burden of mental disorders in Jordan has grown significantly over three decades. Limited resources, stigma, and regional instability worsen the issue. Policies focusing on stigma reduction, mental health integration, and prevention are essential.

Exploring the interplay between mitochondrial dysfunction, early life adversity and bipolar disorder

OBJECTIVE

Mitochondria are essential for energy production and reactive oxygen species (ROS) generation, with changes in ROS levels or energy demands affecting mitochondrial DNA (mtDNA) copy numbers, indicating mitochondrial function. Early life adversity (ELA) affects mitochondrial dynamics, influencing long-term health. Both ELA and mitochondrial abnormalities have been independently associated with bipolar disorder (BD). This study aims to explore the complex interplay between mitochondrial dysfunction, ELA, and BD.

METHODS

The study included 60 participants diagnosed with BD and 66 healthy controls (HCs). Data were collected using the Childhood Trauma Questionnaire (CTQ), and leukocyte mtDNA copy number (MCN) was determined from blood samples.

RESULTS

The results indicated the CTQ sum scores were significantly higher in the BD group, reflecting greater exposure to ELA. In HCs, a marginally significant nonlinear relationship between the square of the CTQ sum score and MCN was found. Further analysis demonstrated a significant interaction between ELA and BD on MCN (p = 0.023), highlighting a critical connection between ELA and mitochondrial dysfunction in BD and reinforcing its biological underpinnings.

CONCLUSIONS

Future treatments for BD might target mitochondrial dysfunctions related to chronic stress, with potential pharmaceuticals designed to address these issues and mitigate the negative effects of chronic stress.

The long-term impact of childhood sexual assault on depression and self-reported mental and physical health

Background

Childhood trauma, including sexual assault (CSA), is a known risk factor for adverse mental health outcomes. This study quantifies the impact of CSA on the likelihood of being diagnosed with depression in adulthood, as well as its influence on poor mental and physical health days.

Methods

We analyzed data from the Behavioral Risk Factor Surveillance System (BRFSS) (2016-2023), comprising 321,106 respondents. The primary exposure was self-reported CSA, while the main outcomes were depression diagnosis, poor mental health days, and poor physical health days. Covariates included race, gender, marital status, employment, age, education, state, year, language spoken at home, metropolitan status, and urban residence. We employed Inverse Probability Weighting (IPW) to estimate the Average Treatment Effect (ATE), controlling for confounders and incorporating state and year fixed effects. Sampling weights ensured national representativeness, and robust standard errors accounted for clustering by state.

Results

In a matched cohort of 15,150 individuals with CSA and 15,150 controls, the CSA group had an average age of 50.3 ± 16.3 years, with most being White (69.3%) and female (76.7%). CSA was significantly associated with an increased risk of depression diagnosis, with a 22.1 percentage-point increase for those with one CSA experience (ATE = 0.221, 95% CI: 0.192-0.250, p < 0.001) and a 24.4 percentage-point increase for those with multiple CSA experiences (ATE = 0.244, 95% CI: 0.222-0.266, p < 0.001). CSA also impacted mental health. Those with a single CSA exposure reported 2.8 more days of poor mental health per month (ATE = 2.829, 95% CI: 2.096-3.398, p < 0.001), while those with multiple exposures reported 4.2 more days (ATE = 4.175, 95% CI: 3.609-4.740, p < 0.001) compared to controls. Regarding physical health, individuals with one CSA exposure reported 1.5 additional poor physical health days (ATE = 1.538, 95% CI: 0.788-2.289), while those with multiple exposures experienced 2.6 additional days (ATE = 2.587, 95% CI: 1.941-3.232).

Conclusion

This study provides robust evidence that CSA significantly increases the likelihood of depression in adulthood and leads to more poor mental and physical health days. The findings underscore the cumulative impact of multiple CSA exposures on health outcomes and emphasize the need for trauma-informed healthcare, early intervention, and public health strategies to mitigate the long-term consequences of CSA.

Complex Intersections Between Adverse Childhood Experiences and Negative Life Events Impact the Phenome of Major Depression

Background

There is evidence that adverse childhood experiences (ACEs) and negative life events (NLEs) are associated with major depression (MDD).

Purpose

To determine whether ACEs affect all features of mild MDD, including suicidal tendencies, brooding, neuroticism, insomnia, cognitive deficits, severity of depression and anxiety, and cognitive deficits, and whether NLEs mediate these effects.

Sample of the Study and Methods

This study examines a cohort of 118 academic students, namely 74 students who satisfied the DSM-5-TR criteria for MDD and 44 normal control students. We assessed brooding, neuroticism, suicidal ideation and attempts, and the severity of depression, anxiety, insomnia, and the Stroop tests.

Results

One validated factor could be extracted from brooding, neuroticism, current suicidal behaviors, and the severity of depression, anxiety, and insomnia, labeled the phenome of depression. A large part of the variance in the phenome of depression (55.0%) was explained by the combined effects of self-, relationships, and academic-related NLEs in conjunction with ACEs, including family dysfunction and abuse and neglect (both physical and emotional). The latter ACEs significantly interacted (moderating effect) with NLEs to impact the depression phenome. Although sexual abuse did not have direct effects on the phenome, its effects were mediated by NLEs. We discovered that increased sexual abuse, physical and emotional abuse and neglect, and ACEs related to family dysfunction predicted 22.5% of the variance in NLEs. Up to 18.5% of the variance in the Stroop test scores was explained by sexual abuse and the phenome of depression. The latter mediated the effects of NLEs and abuse, neglect, and family dysfunction on the Stroop test scores.

Conclusion

Complex intersections between ACEs and NLEs impact the phenome of depression, which comprises neuroticism, brooding, suicidal tendencies, and the severity of insomnia, anxiety, and depression, while sexual abuse together with other ACEs and NLEs may impact cognitive interference inhibition.

Prostitution in the shadow of life-long sexual abuse: Arab women's retrospective experiences

The present study uses the life-course and intersectionality perspectives to explore the meaning that aging Arab women attribute to their lived experiences of life-long sexual abuse in the shadow of engaging in prostitution. Interpretive phenomenological analysis was used to analyze the narratives of 10 older Arab women in Israel who were engaged in prostitution. Four themes emerged: experiencing childhood in the shadow of sexual abuse, becoming a prostitute, being entrapped in prostitution, and settling accounts with the native culture. Women aging in prostitution experience a harsh reality of abuse and loss. The present study points to multiple channels of abuse throughout the life course, from childhood until old age.

Piloting an Alternative Implementation Modality for a School-Based Child Sexual Abuse Prevention Curriculum

BACKGROUND

In the U.S., the most pervasive child sexual abuse (CSA) prevention strategy involves school-based prevention programs; however, the reach of these programs is limited due to implementation constraints, such as budgets or turnover. This is notable as standard delivery of often requires two facilitators in the classroom. Leveraging a natural experiment in the implementation of Safe Touches, the current study sought to explore the feasibility of implementation with a single facilitator using pre-recorded videos compared to the standard in-person delivery.

METHODS

A six-item CSA-related knowledge questionnaire was delivered to (N = 1480) second-graders post-workshop. An independent-samples t-test was used to compare the mean of CSA-related knowledge item responses for each delivery modality. Student-level data were paired with teacher evaluations and an interview with the facilitator.

RESULTS

Across workshops delivered in 25 schools, there was no significant difference in knowledge based on CSA-related questions by workshop modality. Teachers indicated the facilitators responded effectively to the children's questions and comments in both delivery modalities. Input from the facilitator was positive.

CONCLUSIONS

Triangulation of student knowledge, teacher input, and facilitator experience indicates the viability and feasibility of this implementation strategy for Safe Touches, and potentially other school-based CSA prevention programs. To ensure equitable access to the CSA prevention program, the empirical examination of, and investment in, alternative implementation options for school-based CSA preventive programs is encouraged.

A systematic review of the measurement properties of self-report screening tools to detect risk or exposure to child sexual abuse for children under 12

Child sexual abuse (CSA) is a substantial public health issue that is challenging to measure epidemiologically due to the "pact of silence" among those involved. Validated tools could contribute to early recognition or risk detection for CSA. We aimed to systematically assess self-report tools' measurement properties and methodological quality that detect risk or exposure to CSA for children under twelve. The search strategy, selection criteria, data extraction, data analysis, and synthesis followed the COSMIN methodology for systematic reviews (2018). PROSPERO 2021 registration CRD42021278465. MEDLINE, COCHRANE, EMBASE, CINAHL, SCOPUS, and ERIC were searched until August 2021, with an updated search on September 23, 2021, and unlimited by language. The inclusion criteria were: to assess risk or exposure to CSA under twelve years old by objective items and self-report tools; sexual violence risk or exposure in the domestic context; the application context should include health facilities (such as hospital emergency rooms, outpatient clinics, pediatric wards, psychology centers, social services), education (such as schools) and community; no language or date restriction. The exclusion criteria were: non-self-report tools studies, comprehensive articles, comments, editorials, expert opinions, and studies of projective techniques. The COSMIN risk of bias checklist was used to evaluate the methodological quality of the included studies. Feasibility aspects were assessed. This study had no funding source; 29 studies describing eight tools met eligibility criteria. No single instrument reported all nine measurement properties outlined by the COSMIN methodology. The strength of the evidence was moderate to high for six out of eight instruments. ICAST-C and JVQ were the tools that obtained the highest number of rated measurement properties and strength of evidence.

Creating the necessary infrastructure for a trauma-informed system of care for children and youth

Understanding and addressing the impact of adverse life events is an important priority in the design of helping systems. However, creating trauma-informed systems requires efforts to embed effective trauma-informed work in routine practice. This article discusses a model for developing trauma-informed systems using the Transformational Collaborative Outcomes Management (TCOM) framework, a strategy for engineering person-centered care. Person-centered care is naturally congruent with trauma-informed care. We describe the initial stages of implementation of a trauma-informed standardized assessment process to support the sustained evolution of trauma-informed care. Distinguishing between traumatic experiences and traumatic stress is fundamental to an effective trauma-informed system. We describe two sets of analyses-one in a statewide child welfare system and the other in a statewide behavioral health system. These projects found opportunities in the analysis of the detection of traumatic stress based on traumatic experiences to inform practice and policy. Being trauma-informed in child welfare is distinct from being trauma-informed in behavioral health. In child welfare, it appears that a number of children are resilient in the face of traumatic experiences and do not require trauma treatment interventions. However, delayed and missed traumatic stress responses are common. In behavioral health, misses often occur among adolescents, particularly boys, who engage in acting out behavior. Opportunities for the ongoing development of trauma-informed systems using the TCOM framework are discussed.

"I'm in a Bloody Battle without Being Able to Stop It": The Dissociative Experiences of Child Sexual Abuse Survivors

Dissociation in child sexual abuse (CSA) survivors remains under-recognized and diagnosed, partly because of the difficulties involved in identifying dissociative symptoms. Qualitative research can contribute to a better understanding of the lived experiences of dissociation. This study focused on the experiences of dissociation in the context of CSA. In all, 22 female incest survivors, all diagnosed with different dissociative disorders, provided narratives about their experiences of dissociation. The narratives were analyzed using interpretative phenomenological analysis. The narrative analysis revealed four central themes. The first theme deals with reliving the experience of the abuse. The second theme refers to the experience of disconnection from the body, the self, and the surroundings. The third theme covers the lack of coherence in the narrative, and the fourth theme describes the bridge between voluntary controlled and nonvoluntary uncontrolled use of dissociation. The data are discussed in light of several traumagenic constructs, including a lack of self-sense, being entrapped in a victim-aggressor relationship, and distorted time perception. It is suggested that the extent to which participants can control their dissociation and the coherency of their narratives reflects the severity of their dissociation. Clinicians can consider helping clients use dissociation as an adaptive defense mechanism.
