Child sexual abuse and the development of psychiatric disorders: a neurobiological trajectory of pathogenesis

Child maltreatment and behavioral health outcomes in child welfare: Exploring the roles of severity and polyvictimization

BACKGROUND

Child maltreatment and polyvictimization are known risk factors for long-term detrimental health and development outcomes, including behavioral health challenges. However, effects from specific types and combinations of maltreatments are unclear. This study examined the association between maltreatment or polyvictimization and behavioral health in a child welfare sample.

PARTICIPANTS AND SETTING

Medical records of children with child welfare involvement with at least one behavioral health condition (i.e., mental, behavioral or neurodevelopmental disorder, ICD-10 F01-F99) between 1/1/2018-12/31/2021 were extracted from a large, academic hospital system.

METHODS

Behavioral health complexity was categorized as non-chronic, non-complex chronic, or complex chronic using the Pediatric Medical Complexity Algorithm. Partial proportional logistic regression models adjusted for age, sex, race/ethnicity, caregiver type, and physical health complexity generated odds of behavioral health complexity by maltreatment type (physical abuse, sexual abuse, neglect) and maltreatment combinations.

RESULTS

The analytic sample included 3992 participants (mean age 7.6 (Standard Deviation, 5.0) 44 % female, 29 % white, 32 % black, 22 % Hispanic). Participants who experienced physical abuse (Odds Ratio [OR]: 1.79, 95 % Confidence Interval [CI]: 1.10-2.91), or neglect (OR: 1.69, 95 % CI: 1.38-2.07) were more likely to have increasing behavioral health complexity versus those without maltreatment. Participants with both physical abuse and neglect were over twice as likely (OR: 2.44, 95 % CI: 1.88-3.16) to have increasing behavioral health complexity versus those who did not experience maltreatment.

CONCLUSION

Results emphasize the differential impacts of maltreatment and polyvictimization exposures on behavioral health complexity among children with child welfare involvement that can guide risk assessment and clinical care.

An Unusual Presentation of Syphilis in the Context of Child Sexual Abuse

A 13-year-old presented with a genital lesion, which helped in guiding a diagnosis of child sexual abuse. The patient disclosed unprotected penile-vaginal penetration by a 20-year-old male neighbor. On exam, her left labia minora had a single 2-cm hypopigmented fleshy non-tender mass, and laboratory studies revealed positive Treponemal IgG IgM antibody (>8) and rapid plasma reagin titer of 1:128, indicating syphilis infection. Given the resolution of the labial mass with treatment of syphilis, this lesion was most consistent with condyloma lata. Genital exams are an important component of pediatric evaluations. Condyloma lata can vary in appearance (papules, nodules, or wart-like lesions) and color and may present as a single lesion or multiple lesions. Our patient had one 2-cm lesion, and therefore, clinicians should assume that an anogenital lesion is condyloma lata in the setting of positive syphilis testing.

Child sexual abuse, mental health, and legislation in India and Thailand: A cross-country comparison

INTRODUCTION

Child sexual abuse (CSA) is a serious public health issue in India and Thailand. To identify potential barriers for addressing CSA in these countries, it is necessary to explore and compare research, laws, and policies in these two countries.

MATERIAL AND METHODS

The Scopus and PubMed databases were searched for published literature on "Child Sexual Abuse" AND "India" OR "Thailand" concerning research focus, prevalence, factors, and policies or interventions on CSA. Main legislations related to CSA were compared using a predefined outline. Additionally, authors compared and analysed current legislation in relation to the United Nations Convention on the Rights of the Child (UNCRC).

RESULTS

Published literature (n = 64) included original articles (n = 26), reviews (n = 36), editorials or letters to the editor (n = 2). No collaboration on CSA between the two countries was found. Several differences in the main legislation (e.g., punishment, services) of India and Thailand were observed, both between countries and in relation to the UNCRC.

CONCLUSION

Our findings suggest that CSA is mostly under-researched in both countries in terms of services, policy and legislation. There is a need for cross-country, multidisciplinary, and collaborative research on CSA in both India and Thailand.

How parents experience their adolescent's disclosure of previous sexual abuse: a qualitative study

INTRODUCTION

Parents whom adolescents disclose sexual abuse face both a personal traumatic experience, and the need to support their child who is going through a grueling period and needs them. Many quantitative studies exploring the psychological impact of disclosure on parents have been conducted, but few have used qualitative methods. The objective of this study is to explore parents' experiences of their adolescent's disclosure of sexual abuse during psychiatric care, identify the possible beneficial factors and shortcomings, share this knowledge, and improve interventions for these families.

METHODS

We conducted semi structured interviews with parents whose children disclosed sexual abuse during their psychiatric care in Paris and analyzed these interviews using a phenomenological framework (interpretative phenomenological analysis).

RESULTS

This study analyzed 13 semi structured interviews of 9 mothers and 4 fathers whose children were then aged 14 to 17 years. Qualitative analysis uncovered three themes: (1) Parents: alerts and search for support; (2) Between parents and adolescents: a disruption in relationships linked to the disclosure and its legal consequences; (3) Disclosure at the family level: the possible reactivation of a traumatic past and the search for a new equilibrium.

CONCLUSIONS

Considering the parental experience is essential in caring for adolescent patients after they disclose sexual abuse. The need for parental or family psychological support should be systematically assessed. Possible resurgence of parental trauma requires psychiatrists' careful consideration.

The experience of childhood sexual abuse: An exploratory description of psychological and adaptive functioning in Canadian men

BACKGROUND

Childhood sexual abuse (CSA) affects a number of men yet knowledge gaps remain around comprehensively describing psychological and adaptive outcomes for this population.

OBJECTIVE

Examine how a Canadian sample of men with and without CSA histories compares on broader areas of psychological and adaptive functioning.

PARTICIPANTS AND SETTING

This exploratory study included 109 adult men aged 25-60 years who were grouped according to whether they experienced CSA (n = 69) or not (n = 40). Participants were recruited from Ottawa, Ontario, Canada.

METHOD

Using a multi-method approach, we conducted an exploratory and comprehensive examination of how CSA contributes to various areas of psychological (e.g., depression, anxiety, stress, dissociation, anger, PTSD) and adaptive functioning (e.g., friendship quality, employment) using self-report and clinician-administered measures.

RESULTS

CSA men were an average of 8.5 years old at abuse onset. Most (62.3 %) had disclosed their CSA experience, waiting an average of 13.6 years before disclosure. After controlling for covariates (i.e., other types of maltreatment, non-maltreatment adversities, education, income), results indicated a significant association between CSA and men's psychological functioning, but not their adaptive functioning.

CONCLUSIONS

Findings highlight the importance of broadening our understanding of how the experience of CSA, controlling for important covariates, can contribute to the well-being of men in order to better respond to their psychological needs.

Anxiety and Depression Symptoms among Youth Survivors of Childhood Sexual Abuse: A Network Analysis

BACKGROUND

Previous studies have frequently reported a high prevalence of co-occurring anxiety and depression among people who experienced stressful events in childhood. However, few have noted the symptomatic relationship of this comorbidity among childhood sexual abuse (CSA) survivors. Therefore, this study's objectives were as follows: (1) to examine the relationship across symptoms between anxiety and depression among CSA survivors; (2) to compare differences between male and female network structures among CSA survivors.

METHODS

A total of 63 Universities and Colleges in Jilin Province, China, covered 96,218 participants in this study, a sub-set data of which met the criteria of CSA was analyzed with the network analysis. The Childhood Trauma Questionnaire-Short Form (CTQ-SF), measured CSA. Anxiety was measured by the seven-item Generalized Anxiety Disorder Scale (GAD-7), and depression was measured by the Patient Health Questionnaire (PHQ-9). The sex difference between anxiety and depression among CSA survivors was compared.

RESULTS

3,479 college students reported the experience of CSA (CTQ-SF total scores ≥ 8), with a prevalence of 3.62% (95% CI: 3.50-3.73%). Among CSA survivors, control worry, sad mood, and energy were central and bridge symptoms of the anxiety and depression network. Meanwhile, male CSA survivors appeared to have a stronger correlation between guilt and suicide, but female CSA survivors seemed to have a stronger correlation between control worry and suicide. Moreover, the edge of control worry-relax-afraid was stronger in the male network, while the edge of restless-relax was stronger in the female network.

CONCLUSION

Control worry, sad mood, and energy are crucial to offer targeted treatment and to relieve anxiety and depression symptoms for CSA survivors. Guilt needs more attention for male CSA survivors, while control worry remains more important for female CSA survivors to reduce suicidal ideation and suicide attempts.

Examining the attitudes of sexually abused and non-abused individuals towards marriage in terms of ambivalent sexism

The research aims to examine the attitudes of individuals who are victims of abuse and those who are not towards marriage in terms of ambivalent sexism. The research study group consists of 718 individuals between the ages of 18-48. Research data were collected with the Inonu Marriage Attitude Scale and Ambivalent Sexism Inventory. As a result of the correlation analysis, it was concluded that the marriage attitude was positively and significantly correlated with hostile and protective sexism. However, since the relationship between hostile sexism and attitudes towards marriage is lower than that of protective sexism, hostile sexism was not included in the model as a control variable. In the covariance analysis, it is seen that protective sexism and sexual abuse predict the attitude towards marriage at a statistically significant level. In addition, when the effect of sexual abuse on the attitude towards marriage was examined by controlling the protective sexism variable, it was found that it was statistically significant without the effect of sexism. According to the findings, it was determined that individuals who were not victims of sexual abuse had higher attitudes towards marriage than those who were victims.

"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.

Association between the experience of sexual violence and insomnia in a national sample of French adults

PURPOSEL

The experience of sexual violence has been associated with sleeping disorders; however, few studies have examined this association using a large sample of the general population. This study investigates whether lifetime experience of sexual violence and childhood experience of sexual violence are associated with insomnia.

METHODS

Our study is based on data from the 2017 French Health Barometer, a general population phone cross-sectional survey, which included 25 319 adults aged 18-75 years in 2017. Questions regarding sleep quality were asked to 12 560 participants, and insomnia was defined according to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). We conducted adjusted Log-binomial regressions to examine the association between the experience of sexual violence and insomnia by calculating adjusted Prevalence Ratios (PRa; 95% CI).

RESULTS

The weighted prevalence of insomnia was 13.5%, with women more affected than men (17.9% vs 9.6%). The prevalence of lifetime experience of sexual violence was around 3 times higher among those who suffer from insomnia (12.3%) compared to those who do not (4.5%). The adjusted associations between lifetime experience of sexual violence and insomnia, as well as between childhood experience of sexual violence and insomnia were both statistically significant (PRa = 1.79; 95% CI: 1.59-2.02; and PRa = 1.42; 95% CI: 1.23-1.64 respectively).

CONCLUSIONS

Sexual violence could explain the substantial sex-difference in insomnia. Our findings reiterate the importance of systematically screening for sexual violence among patients suffering from sleep disorders to propose adequate trauma-informed interventions.

Parenting Stress in Non-Offending Caregivers of Sexually Abused Children

The non-offending caregiver (NOC) population is under studied despite their role in the recovery of child victim-survivors of sexual abuse. Research suggests that NOCs experience significant distress following a child's disclosure of sexual abuse. Trauma has been demonstrated to negatively impact the caregiver-child relationship. This study informs about common NOC stress reactions in response to child sexual abuse (CSA) disclosures and has clinical implications for treating families affected by CSA. Participants included 66 NOCs (age 23-66, M = 41.09, SD = 10.26) who participated in clinical intakes at a CSA treatment program and completed a self-report measure of parenting stress. Depending on the child's age, NOCs were administered either the Parenting Stress Index-fourth edition, Short Form (PSI-4-SF) or the Stress Index for Parents of Adolescents (SIPA). NOCs reported higher than average parenting stress. Statistically significant differences between the clinical and normative samples were found on all PSI-4-SF domains and on majority of SIPA domains. High to Clinically Significant scores were reported by 42% of NOCs for Parent-Child Dysfunctional Interaction. Stress related to their child's social withdrawal was reported by 56% of NOCs. This study provides comparison data for evaluations of NOCs. NOCs may require treatment and family-based approaches are implicated.

Determinants of Sexual Abuse Prevention Knowledge among Children’s Schools in West Java Indonesia: A Cross-Sectional Study

Child sexual abuse (CSA) is a severe problem in Indonesia. Adequate knowledge in children about CSA prevention is essential so that children do not become victims. Lack of adequate children’s knowledge of the prevention of CSA may put them at risk for experiencing CSA. This cross-sectional study explores the association factors between knowledge and characteristics regarding the prevention of CSA. The study was conducted in Bandung Regency, West Java, Indonesia. Students from grades two to nine at two elementary schools were eligible for the study. Results showed that as sources of information associated with better knowledge of CSA prevention (p = 0.00), teachers and parents significantly contributed to CSA information. Multivariate analysis showed that teachers (OR: 33.479, 95% (CI: 4.467–250.912)) and parents (OR: 45.336, 95% (CI: 10.886–188.807)) significantly contributed as a source of CSA information among students. The findings are essential important implications for interventions intended at preventing CSA. Sexual education programs should be officially applied at schools for children with the support of their parents and teachers.

Disclosing Child Sexual Abuse to a Health Professional: A Metasynthesis

Objective

Sexual abuse is a major public health problem. Its disclosure to a health professional could help to reduce its impact on survivors' lives. The objective of this metasynthesis, combining a systematic review and an analysis of the qualitative studies, was to explore the qualitative literature concerning the experience of a survivor disclosing sexual violence experienced in childhood to a health professional, from the perspective of both.

Methods and Data Sources

We used four databases and two journals (Medline, PsycINFO, EMBASE, and SSCI, and the Journal of Sexual Abuse and Child Abuse and Neglect) to identify studies concerning this disclosure of sexual abuse to healthcare professionals from the point of view of the survivors and the health professionals. After assessing the methodological quality of the articles with the "Critical Appraisal Skills Program (CASP)," we conducted a thematic analysis of the data extracted during the review.

Results

This review includes 20 articles, covering the data of 612 participants: 291 who were adults at the time of the study but abused in childhood, 152 minors, 14 parents of adolescents, and 155 healthcare professionals. Two themes emerged from the analysis: (1) the disclosure as experienced by the professionals, and (2) the disclosure as experienced by the survivors.

Conclusion

Our results show that survivors had a diachronic approach to the experience of disclosure. They suggest a change over time in how survivors experience disclosure: relief and release were seen only among the adult participants, at a distance from - long after - the disclosure. This study made it possible to identify new perspectives for research in the field of child psychiatry and to formulate concrete clinical proposals, in particular, by applying the principle of patient experts to involve now-adult survivors in training and increase the awareness of the healthcare professionals concerned.

Recognizing the importance of childhood maltreatment as a critical factor in psychiatric diagnoses, treatment, research, prevention, and education

Childhood maltreatment is the most important preventable risk factor for psychiatric disorders. Maltreated individuals typically develop psychiatric disorders at an earlier age, have a more pernicious course, more comorbidities, greater symptom severity, and respond less favorably to treatments than non-maltreated individuals with the same primary DSM-5 diagnosis. Furthermore, maltreated individuals have alterations in stress-susceptible brain regions, hypothalamic-pituitary-adrenal response, and inflammatory marker levels not discernible in their non-maltreated counterparts. Hence, maltreated and non-maltreated individuals with the same primary DSM-5 diagnoses appear to be clinically and neurobiologically distinct. The failure to embody this distinction in DSM-5 has interfered with our ability to discover novel treatments, to recommend currently available treatments most likely to be efficacious, and has been a largely unrecognized confound that has thwarted our ability to identify the biological basis for major psychiatric disorders. Incorporating this distinction into DSM will help transform this sign and symptom-based classification system to a more etiologically informed nosology. We discuss several diagnostic alternatives and recommend the inclusion of a Developmental Trauma Disorder diagnosis for severely dysregulated individuals, of all ages, with numerous comorbidities, who experienced interpersonal victimization and disruptions in attachment, such as emotional maltreatment or neglect. For less severely affected maltreated individuals, we suggest using conventional diagnostic categories, such as major depression, but with an essential modifier indicating a history of childhood maltreatment, or early life stress, to delineate the ecophenotypic variant. Implementing this strategy should improve our ability to effectively diagnose and treat individuals with psychiatric disorders and to accelerate discovery.

Associations between PTSD symptoms and other psychiatric symptoms among college students exposed to childhood sexual abuse: a network analysis

Background: Childhood sexual abuse (CSA) is one of the prevalent forms of trauma experienced during childhood and adolescence. Previous research underscores its associations with depression, anxiety, post-traumatic stress disorder (PTSD), and psychosis. Objective: This study examined symptom connections between depression, anxiety, PTSD, and psychosis while simultaneously investigating whether these connections differed by gender among CSA survivors. Methods: A large-scale, cross-sectional study among 96,218 college students was conducted in China. Participants' CSA was measured by the Childhood Trauma Questionnaire-Short Form (CTQ-SF). Participants' PTSD, psychosis, depression, and anxiety were measured by the Trauma Screening Questionnaire (TSQ), the Psychosis Screener (PS), the nine-item Patient Health Questionnaire (PHQ-9), and the 7-item Generalized Anxiety Disorder Scale (GAD-7), respectively. Network analysis was used to explore the potential associations between these symptoms and to compare the sex differences in the symptoms model. Results: Among participants who suffered from CSA, females were more likely from left-behind households, while males were more likely from households with a high annual income (P < .001, Cohen's W = 0.07). In addition, compared to male victims, female victims were more likely to report depression, anxiety, and PTSD (P < .001, Cohen's d≈0.2), while male victims were more likely to report psychosis (P < .001, Cohen's d = 0.36). Results from network estimation showed that psychosis, depression, anxiety, and PTSD symptoms were positively correlated. Moreover, psychosis had a stronger connection with PTSD symptoms, including hypervigilance, intrusive thoughts, and physiological and emotional reactivity. Conclusions: The current study explores the associations between PTSD symptoms and psychiatric symptoms among college students exposed to CSA using a network analysis approach. These crucial symptoms of PTSD may have potential connections to psychosis. Target intervention and strategy should be developed to improve mental health and quality of life among these CSA victims. Furthermore, longitudinal studies are warranted to advance our understanding of PTSD and psychosis.

Prevalence of adult sexual abuse in men with mental illness: Bayesian meta-analysis

BACKGROUND

Sexual abuse is a broad category of traumatic experiences that includes rape and any unwanted sexual contact with a body part or foreign object, whether penetrative, oral or otherwise. Although patients with mental illness have a higher risk of becoming victims of sexual abuse in adulthood, few studies investigate the proportion of male victims in this population. Their underrepresentation in research is a barrier to understanding the negative outcomes associated with sexual abuse in men.

AIMS

We estimated the prevalence of recent (past year) and adulthood sexual abuse perpetrated by any perpetrator and separately by intimate partners in males diagnosed with a mental illness.

METHOD

To model the prevalences and heterogeneity arising from reports, we used Bayesian multilevel models. Prevalences were estimated for mixed-diagnosis, substance misuse, intellectual disability and post-traumatic stress disorder samples, and studies reporting specifically on intimate partner violence. This review was registered through PROSPERO (CRD42020169299).

RESULTS

Estimated adult sexual abuse was 5.3% (95% Credibility Interval 1.6-12.8%) for past-year abuse and 14.1% (95% Credibility Interval 7.3-22.4%) for abuse in adulthood. There was considerable heterogeneity of prevalence between studies and diagnosis groups.

CONCLUSIONS

Our analyses show that the prevalence of sexual abuse of males diagnosed with a mental illness was much higher than for men in the general population. This has important implications regarding the proportion of undetected or untreated sexually abused men in clinical practice.

Relationship between childhood trauma, personality, social support and depression in women attending general medical clinics in a low and middle-income country

BACKGROUND

Associations between childhood trauma, personality, and Major Depressive Disorder (MDD) have been well established in studies conducted in high-income countries. However, there are limited studies on these associations in low and middle-income countries (LMICs), where MDD is highly prevalent. We assessed the relationships between childhood trauma, personality, and MDD in women in Karachi, Pakistan.

METHOD

In this cross-sectional study of 455 female patients attending general medical outpatient clinics, a diagnosis of MDD was confirmed using the Structured Clinical Interview for DSM-IV (SCID); retrospective reports of childhood trauma were collected using the childhood trauma questionnaire (CTQ); and Big Five personality traits were assessed using the NEO Personality Inventory Revised (NEO PI-R). Other measures included the Life Events Questionnaire (LEQ) and the Multidimensional Scale of Perceived Social Support (MSPSS). Factors independently associated with MDD were determined using logistic regression analyses.

RESULTS

Of the 455 women recruited between August 1, 2011 and July 31, 2013, 242 (53%) had a diagnosis of MDD. Women with MDD were significantly more likely to be separated, had more stressful life events and higher CTQ scores. Higher perceived social support, conscientiousness and extraversion were independently associated with significantly reduced odds of MDD. There were no significant associations between CTQ scores and any of the NEO PI-R subscales.

LIMITATIONS

Ratings of childhood trauma were based on retrospective recall.

CONCLUSION

MDD and a history of childhood trauma were highly prevalent in Pakistani women attending general medical clinics. Interventions to prevent childhood trauma and promote social support in women may improve public mental health in LMICs like Pakistan.

A history of childhood trauma and allostatic load in patients with psychotic disorders with respect to stress coping strategies

Elevated allostatic load (AL) index, which is a cumulative measure of biological dysregulations associated with stress exposure, has been demonstrated in patients with psychosis. However, it remains unknown whether a history of childhood trauma (CT) might contribute to elevated AL index in psychosis. Therefore, we aimed to investigate the association between AL index, a history of CT and coping styles in patients with psychotic disorders. Participants were 65 patients with schizophrenia-spectrum disorders and 56 healthy controls (HCs). The AL index was computed based on percentile distributions of 15 biomarkers in HCs. The AL index was significantly higher in patients with psychosis. A history of parental antipathy was associated with elevated AL index in both groups of participants. A history of any categories of CT and sexual abuse were associated with higher AL index only in patients with psychosis. Social diversion (seeking social interactions in case of stressful experiences) mediated the association between sexual abuse and the AL index in the group of patients. There was a significant direct effect of sexual abuse on the AL index (this specific CT was associated with higher AL index). However, indirect effect of sexual trauma on AL through social diversion was opposite to direct effect. Childhood adversities, especially sexual abuse and parental antipathy, might contribute to elevated AL index in patients with psychosis. The effect of sexual abuse on the AL index might be specific to psychosis. Engagement in social interactions in case of stressful situations might alleviate biological dysregulations associated with CT.

Psychological evaluation of children victims of sexual abuse: development of a protocol

Sexual abuse (SA) is associated with significant psychological problems in childhood, making it increasingly important to develop evaluation protocols. This study examined clinical aspects and cognitive measures of 49 children (24 with SA history and 25 controls). It employed a SA assessment questionnaire, clinical evaluations of posttraumatic stress disorder, risk indicators and neuropsychological tests in order to elaborate a specific forensic psychological evaluation protocol for this population. Conflicting couples (80%), separated parents (68%) and parents' alcohol/drug abuse (76%) were revealed as major risk factors. Fathers represented the primary perpetrator (24%). The main cognitive complaint was difficulty concentrating. Regarding the association between clinical and cognitive variables, it was observed that children who were anxious or referred to having fear, difficulties with operational memory and difficulty sleeping, had more trouble performing tasks that required attention and memory (operational, immediate and late). Children with SA history demonstrated inferior performance in visual attention/task switching and memory; with an emphasis in the loss of set in the Wisconsin test. The findings suggest the possibility of a primary attention deficit in children with SA history, possibly influencing the performance of other cognitive functions.

Child abuse interacts with hippocampal and corpus callosum volume on psychophysiological response to startling auditory stimuli in a sample of veterans

Child abuse (CA), which is linked to posttraumatic stress disorder (PTSD), has been associated with a reduction in both hippocampal and corpus callosum (CC) volume. However, few studies have explored these relationships on psychophysiological variables related to trauma exposure. Therefore, we assessed whether the interaction between CA and hippocampal and CC volume were associated with enhanced fear potentiated psychophysiological response patterns in a sample of Veterans. 147 Veteran participants who were part of a larger study of Gulf War Illness were exposed to startling sounds in no, ambiguous, and high threat conditions and also provided MRI data. The Clinician Administered PTSD Scale and Trauma History Questionnaire were used to measure PTSD and CA respectively. Psychophysiological response was measured by EMG, SCR, and heart rate. Repeated-measures mixed linear models were used to assess the significance of CA by neural structure interactions. CA interacted with both hippocampal and CC volume on psychophysiological response magnitudes, where participants with CA and smaller hippocampal volume had greater EMG (p < 0.01) and SCR (p < 0.05) magnitudes across trials and over threat conditions. Participants with CA and smaller CC volume had greater SCR magnitudes across trials and over threat conditions (p < 0.01). Hippocampal and genu volume mediated CA and psychophysiological response magnitude. CA may impact psychophysiological response via a reduction in hippocampal and CC volume. Volumetric reduction in these structures may indicate a neurofunctional, CA-related increase in threat sensitivity, which could portend increased PTSD susceptibility and adverse interpersonal and social consequences across the lifespan.

Psychiatric Impact of Organized and Ritual Child Sexual Abuse: Cross-Sectional Findings from Individuals Who Report Being Victimized

Organized and ritual child sexual abuse (ORA) is often rooted in the child’s own family. Empirical evidence on possible associations between ORA and trauma-related symptoms in those who report this kind of extreme and prolonged violence is rare. The aim of our study was to explore socio-demographic and clinical characteristics of the individuals reporting ORA experiences, and to investigate protective as well as promotive factors in the link between ORA and trauma-related symptom severity. Within the framework of a project of the Independent Inquiry into Child Sexual Abuse in Germany, we recruited 165 adults who identified themselves as ORA victims via abuse- and trauma-specific networks and mailing lists, and they completed an anonymous online survey. We used variance analyses to examine correlations between several variables in the ORA context and PTSD symptoms (PCL-5) as well as somatoform dissociation (SDQ-5). Results revealed a high psychic strain combined with an adverse health care situation in individuals who report experiences with ORA. Ideological strategies used by perpetrators as well as Dissociative Identity Disorders experienced by those affected are associated with more severe symptoms (η²_p = 0.11; η²_p = 0.15), while an exit out of the ORA structures is associated with milder symptoms (η²_p = 0.11). Efforts are needed to improve health care services for individuals who experience severe and complex psychiatric disorders due to ORA in their childhood.

Child sexual abuse in India: A systematic review

Objective

Child Sexual Abuse (CSA) is a pressing human right issue and public health concern. We conducted a systematic review of quantitative and qualitative studies published in the past decade on CSA in India to examine the distribution of the prevalence estimates for both genders, to improve understanding of the determinants and consequences of CSA and identify gaps in the current state of research.

Methods

For this systematic review, we searched electronic literature databases (PubMed, POPLINE, and PsycINFO) for articles published in English on Child Sexual Abuse in India between January 1, 2006 and January 1, 2016 using 55 search terms. Data were extracted from published articles only.

Findings

Fifty-one studies met inclusion criteria for the review. The review indicates that prevalence rates of CSA is high among both boys and girls in India. Due to heterogeneity of study designs and lack of standardised assessments, reported prevalence estimates varied greatly among both genders in different studies. There is a need to conduct representative studies using a validated instrument to obtain valid epidemiological estimates. Commercial sex workers, men who have sex with men, and women with psychiatric disorders were at higher risks for sexual abuse during childhood. In addition, the synthesis of qualitative data across studies included in the review suggests that exposure and perpetration of CSA is a multifaceted phenomenon grounded in the interplay between individual, family, community, and societal factors. The review indicates poor physical, behavioural, social, and mental health outcomes of CSA in India. We conclude with a research agenda calling for quantitative and qualitative studies to explore the determinants and perpetration of child sexual abuse in India from an ecological lens. This research agenda may be necessary to inform the development of a culturally tailored primary prevention and treatment strategy for CSA victims in India.
