Child Maltreatment, Abuse, and Neglect: An Umbrella Review of Their Prevalence and Definitions

Childhood psychological maltreatment subtypes and depression among Chinese college students: the role of self-compassion and perceived negative attention bias

BACKGROUND

Research on childhood psychological maltreatment lags behind that on other forms of childhood maltreatment. While it has been identified as a significant predictor of depression, the specific underlying mechanisms linking its subtypes (emotional abuse and emotional neglect) to depression remain unclear. This study aimed to examine the association between childhood psychological maltreatment and its subtypes and depression from both emotional factors (self-compassion) and cognitive factors (perceived negative attention bias), as well as the gender differences.

METHODS

Using a questionnaire survey, a total of 587 college students completed the self-report questionnaires, including childhood psychological maltreatment and its subtypes, self-compassion, perceived negative attention bias, and depression. This study used structural equation models to examine the serial mediating role and gender differences by Amos 24.0.

RESULTS

Childhood psychological maltreatment and its subtypes positively predicted depression. Self-compassion played a mediating role between childhood psychological maltreatment and its subtypes and depression. Perceived negative attention bias played a mediating role between childhood psychological maltreatment and emotional abuse and depression, but not significantly between emotional neglect and depression. Self-compassion and perceived negative attention bias played a serial mediating role between childhood psychological maltreatment (including its subtypes) and depression. There were no gender differences in the mediating role.

CONCLUSION

Self-compassion and perceived negative attention bias played distinct roles in the association between childhood psychological maltreatment, its subtypes, and depression. A serial mediating role of self-compassion and perceived negative attention bias was observed in the associations between overall psychological maltreatment, emotional abuse, and depression. In contrast, in the case of emotional neglect, only self-compassion served as a mediator. These findings enlighten us that psychological interventions enhancing self-compassion and reducing negative attention bias may help mitigate depression in college students exposed to childhood psychological maltreatment, particularly emotional abuse. Conversely, interventions focused on increasing self-compassion may be more effective in reducing depression in those exposed to emotional neglect.

Defining child maltreatment for research and surveillance: an international, multi-sectoral, Delphi consensus study in 34 countries in Europe and surrounding regions

Child maltreatment is a complex public health issue that has consequences across the life-course. Studies to quantify child maltreatment and identify interventions and services are constrained by a lack of uniform definitions. We conducted a European Delphi study to reach consensus on types and characteristics of child maltreatment for use in surveillance and research. Statements were developed following a scoping review and identification of key concepts by an international expert team (n = 19). A multidisciplinary expert panel (n = 70) from 34 countries completed three rounds of an online survey. We defined consensus as ≥70% agreement or disagreement with each statement after the final round. Consensus was reached on 26/31 statements (participant retention rate 94%). From the statements, we propose a unified definition of child maltreatment to improve measurement and surveillance in Europe. Concerted efforts are now required to test and refine the definition further prior to real-world operationalisation.

A Multidisciplinary Approach to Nonepileptic Events

OBJECTIVE

This article provides a guide for neurologists managing nonepileptic events (NEEs), a complex intersection of neurology and psychiatry. It covers risk factors, pathophysiology, current treatment approaches, and prognosis, with specific management strategies for challenging scenarios such as patients with intellectual disabilities and comorbid epilepsy.

LATEST DEVELOPMENTS

An emphasis on strong communication and coordinated care among health care specialists improves patient outcomes and reduces unnecessary medical consultations and procedures. This approach is now recognized as essential for addressing the complex presentation and comorbidities associated with NEEs.

ESSENTIAL POINTS

NEEs are prevalent and highly disabling, and multiple pathophysiologic mechanisms for these events have been proposed. Mortality is comparable with that of patients with treatment-refractory epilepsy, and prognosis is better for children than adults. Achievable treatment goals for adults include improved quality of life and reduced frequency and severity of events, even if complete remission of NEEs is not achieved. Enhanced communication and coordinated care through multidisciplinary care teams enable the efficient use of individual expertise at different treatment stages to address the presentation, risk factors, and comorbidities associated with NEEs, resulting in a better quality of life for patients.

PROTOCOL: Risk and protective factors for child sexual abuse and interventions against child sexual abuse: An umbrella review

This is the protocol for a Campbell Collaboration systematic review. Our objective is to conduct an umbrella review to synthesize published and unpublished systematic reviews focused on risk and protective factors for child sexual abuse and effectiveness of interventions against child sexual abuse perpetration and victimization. Specific research questions are: (i) what are the risk and protective factors for child sexual abuse victimization, and what are their relative strength and/or magnitude for predicting child sexual abuse victimization? (ii) what are the risk and protective factors for child sexual abuse perpetration, and what are their relative strength and/or magnitude for predicting child sexual abuse perpetration? (iii) are interventions aimed at reducing and/or preventing child sexual abuse effective? (iv) what are the moderators that increase or decrease effectiveness of the interventions? Efforts to decrease child sexual abuse need to be based on research, but more accessible evidence regarding the breadth of risk and protective factors and effectiveness of interventions to reduce child sexual abuse needs to be provided to policymakers. This will be the first umbrella review that comprehensively synthesizes findings of the previous systematic reviews that focus on risk and protective factors for child sexual abuse and interventions to prevent or reduce child sexual abuse. The results will be able to inform enhanced prevention policy and programs, and regulatory measures for specific contexts of child sexual abuse.

Psychometric Properties of the Detachment and Compartmentalization Inventory (DCI) in an Italian Community Sample

The Detachment and Compartmentalization Inventory (DCI) is a valid and reliable self-report instrument that assesses these two distinct forms of dissociative symptoms. However, there is limited research on the cross-cultural validation of the DCI. Therefore, this study aimed to develop an Italian translation of the DCI and examine its internal structure and psychometric properties (including internal consistency, convergent validity, and test-retest reliability) within an Italian-speaking community sample. The sample consisted of 1276 adults (887 females; mean age: 29.57 ± 10.96 years), who completed the DCI and other self-report measures evaluating dissociative experiences and childhood trauma. Confirmatory factor analyses supported the original two-factor model (χ2169 = 1312.80, RMSEA = 0.073, 95%CI 0.069-0.077; CFI = 0.94; TLI = 0.94; SRMR = 0.04). Additionally, the DCI exhibited good internal consistency, test-retest reliability, and convergent validity with another measure of dissociation. The study also confirmed the association between DCI scores and the severity of childhood trauma. Finally, a Receiver Operating Characteristic (ROC) curve analysis demonstrated that the DCI effectively distinguishes individuals who screened positively for dissociative disorders. Overall, these findings indicate that the Italian translation of the DCI possesses satisfactory psychometric properties, suggesting its utility as a screening tool for assessing detachment and compartmentalization experiences.

Childhood Trauma, Mentalization and Obsessive Compulsive Symptoms in a Non-Clinical Sample: A Mediation Analysis Study

Objective

Obsessive and compulsive symptoms (OCS) are cross-cutting psychopathological manifestations frequently detected in a variety of clinical and non-clinical samples. It has been suggested that impaired mentalization abilities and traumatic experiences during childhood may be relevant etiopathogenetic factors in the development of OCS. The purpose of the current study was to cross-sectionally assess these variables in a non-clinical sample, testing the mediational role of mentalization abilities in the association between childhood trauma (CT) and OCS.

Method

667 participants (488 females; mean age= 29.76 ± 11.87 years; age range: 18-80) answered a survey including the Childhood Trauma Questionnaire, the Mentalization Questionnaire and the Obsession-Compulsion subscale of the Brief Symptom Inventory.

Results

The mediation model was significant for the total effect (p< .001), showing that CT was positively associated with OCS (95% CI: .006; .019) and that this association was mediated by reduced levels of mentalization capacity (95% CI: .003; .009). Such results were significant controlling for potential sociodemographic and clinical confounding variables.

Conclusions

The findings contribute to elucidate the complex relationships between CT, mentalization capacity, and OCS, supporting the possibility that mentalization impairments, arising from CT, may affect top-down control mechanisms thus contributing to the development of OCS.

Altered EEG Patterns in Individuals with Disorganized Attachment: An EEG Microstates Study

Over the past years, different studies provided preliminary evidence that Disorganized Attachment (DA) may have dysregulatory and disintegrative effects on both autonomic arousal regulation and brain connectivity. However, despite the clinical relevance of this construct, few studies have investigated the specific alterations underlying DA using electroencephalography (EEG). Thus, the main aim of the current study was to investigate EEG microstate parameters of DA in a non-clinical sample (N = 50) before (pre) and after (post) the administration of the Adult Attachment Interview (AAI). Two EEG eyes-closed Resting State (RS) recordings were performed before and after the AAI, which was used for classifying the participants [i.e., Disorganized/Unresolved (D/U) or Organized/Resolved (O/R) individuals] and to trigger the attachment system. Microstates parameters (i.e., Mean Duration, Time Coverage and Occurrence) were extracted from each recording using Cartool software. EEG microstates clustering analysis revealed 6 different maps (labeled A, B, C, D, E, F) in both groups (i.e., D/U and O/R individuals) and in both conditions (i.e., pre-AAI and post-AAI). In the pre-AAI condition, compared to O/R individuals, D/U participants showed a shorter Mean Duration and Time Coverage of Map F; in the post-AAI condition, a significant reduction in the Mean Duration of Map E was also observed in D/U individuals. Finally, in the "within" statistical analysis (i.e., pre-AAI vs. post-AAI), only the D/U group exhibited a significant increase in Time Coverage of Map F after the AAI. Since these maps are associated with brain networks involved in emotional information processing and mentalization (i.e., Salience Network and Default Mode Network), our result might reflect the deficit in the ability to mentalize caregiver's interaction as well as the increased sensitivity to attachment-related stimuli typically observed in individuals with a D/U state of mind.

Genetic evidence for the causal relations between metabolic syndrome and psychiatric disorders: a Mendelian randomization study

Emerging evidence reveals associations between metabolic syndrome (MetS) and psychiatric disorders (PDs), although causality remains uncertain. Consequently, we conducted Mendelian randomization (MR) to systematically evaluate the causality between MetS and PDs. Linkage disequilibrium score regression estimated the heritability of PDs and their genetic correlations with MetS. In primary analyses, the main model employed inverse variance weighting method, with sensitivity analyses using various MR models to ensure robustness. Replication MR analyses, involving cohorts distinct from those in the primary analyses, were performed to validate the generalizability of the findings. Multivariable MR analyses were carried out to account for genetically predicted body mass index (BMI). As a result, genetic correlations of MetS with attention-deficit/hyperactivity disorder(ADHD), anorexia nervosa(ANO), major depressive disorder(MDD), and schizophrenia were identified. Causal effects of MetS on ADHD (OR: 1.59 [95% CI:1.45-1.74]), ANO (OR: 1.42 [95% CI:1.25-1.61]), MDD(OR: 1.23 [95% CI: 1.13-1.33]), and the effects of ADHD (OR: 1.03 [95% CI: 1.02-1.04]) and ANO (OR: 1.01 [95% CI: 1.01-1.02]) on MetS were observed in primary analyses. Results from sensitivity analyses and replication analyses were generally consistent with the primary analyses, confirming the robustness and generalizability of the findings. Associations between MetS and ADHD, as well as ANO persisted after adjusting for BMI, whereas the statistical significance of the association between MetS and MDD was no longer observable. These results contribute to a deeper understanding of the mechanisms underlying PDs, suggesting potential modifiable targets for public prevention and clinical intervention in specific PDs related to metabolic pathways.

Impact of COVID-19 pandemic on characteristics, extent and trends in child maltreatment in 34 Euro-CAN COST Action countries: a scoping review protocol

INTRODUCTION

While the factors commonly associated with an increased risk of child maltreatment (CM) were found to be increased during COVID-19, reports of actual maltreatment showed varying trends. Similarly, evidence regarding the impact of COVID-19 on CM within the European Cooperation on Science and Technology and Network Collaborative (COST) Action countries remains inconsistent. This scoping review aims to explore the extent and nature of evidence pertaining to CM within the countries affiliated with the Child Abuse and Neglect in Europe Action Network (Euro-CAN), funded by the COST.

METHODS AND ANALYSIS

Key electronic databases were searched to identify eligible papers, reports and other material published between January 2020 and April 2023: PubMed, EMBASE, PsycINFO, Social Policy and Practice, Scopus and Web of Science. To cover the breadth of evidence, a systematic and broad search strategy was applied using a combination of keywords and controlled vocabulary for four concepts: children, maltreatment, COVID-19 and Euro-CAN countries, without restrictions on study design or language. Grey literature was searched in OpenGrey and Google Scholar. Two reviewers will independently screen full-text publications for eligibility and undertake data extraction, using a customised grid. The screening criteria and data charting will be piloted by the research team.The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) extension for scoping reviews will be followed to present the results. Results will be summarised in a tabular form and narratively.

ETHICS AND DISSEMINATION

This review will identify and summarise publicly available data, without requiring ethical approval. The findings will be disseminated to the Euro-CAN Network and reported to the COST Association. They will also be published in a peer-reviewed journal. This protocol is registered on Open Science Framework.
