Review
Resting-state functional connectivity (rsFC) has the potential to shed light on how childhood abuse and neglect relates to negative psychiatric outcomes. However, a comprehensive review of the impact of childhood maltreatment on the brain's resting state functional organization has not yet been undertaken. We systematically searched rsFC studies in children and youth exposed to maltreatment. Nineteen studies (total n = 3079) met our inclusion criteria. Two consistent findings were observed. Childhood maltreatment was linked to reduced connectivity between the anterior insula and dorsal anterior cingulate cortex, and with widespread heightened amygdala connectivity with key structures in the salience, default mode, and prefrontal regulatory networks. Other brain regions showing altered connectivity included the ventral anterior cingulate cortex, dorsolateral prefrontal cortex, and hippocampus. These patterns of altered functional connectivity associated with maltreatment exposure were independent of symptoms, yet comparable to those seen in individuals with overt clinical disorder. Summative findings indicate that rsFC alterations associated with maltreatment experience are related to poor cognitive and social functioning and are prognostic of future symptoms. In conclusion, maltreatment is associated with altered rsFC in emotional reactivity, regulation, learning, and salience detection brain circuits. This indicates patterns of recalibration of putative mechanisms implicated in maladaptive developmental outcomes.

Meta-Analysis Review
Childhood emotional abuse (CEA) and childhood emotional neglect (CEN) are the least well-studied forms of childhood maltreatment due to challenges in their definition and in detection. However, the available evidence suggests associations with multiple adulthood mental health problems in clinical and non-clinical populations. This systematic review and meta-analysis (PROSPERO registration number CRD42020197833) explored the associations between CEA and CEN and a range of adulthood mental health problems based on systematic searches of eight databases. In total, 79 English and 11 Chinese studies met our inclusion criteria. Results suggested that CEA and CEN had positive associations with various adulthood mental health problems ( = 0.02-1.84), including depression, anxiety, substance abuse, suicidal ideation or attempts, personality disorders, eating disorders, and other psychological symptoms in the general population and across different geographic regions. Furthermore, findings suggested that compared with the non-clinical population, individuals in clinical populations were more likely to have experienced emotional abuse and neglect during childhood. The review highlights the need for more research on emotional abuse and emotional neglect. Furthermore, future research should include more populations from non-western countries and non-college populations. They further underline the importance of addressing issues related to CEA/CEN experiences in the prevention and treatment of mental health issues in adulthood.

Review
PURPOSE
To investigate whether (1) depression is associated with increased risk of past-year intimate partner violence (IPV) perpetration, disaggregated by sex, after controlling for potential confounders; (2) observed associations are mediated by alcohol misuse or past-year IPV victimisation.
METHODS
Systematic review and individual participant data (IPD) meta-mediation analysis of general population surveys of participants aged 16 years or older, that were conducted in a high-income country setting, and measured mental disorder and IPV perpetration in the last 12 months.
RESULTS
Four datasets contributed to meta-mediation analyses, with a combined sample of 12,679 participants. Depression was associated with a 7.4% and 4.8% proportion increase of past-year physical IPV perpetration among women and men, respectively. We found no evidence of mediation by alcohol misuse. Among women, past-year IPV victimisation mediated 45% of the total effect of depression on past-year IPV perpetration. Past-year severe IPV victimisation mediated 60% of the total effect of depression on past-year severe IPV perpetration. We could not investigate IPV victimisation as a mediator among men due to perfect prediction.
CONCLUSIONS
Mental health services, criminal justice services, and domestic violence perpetrator programmes should be aware that depression is associated with increased risk of IPV perpetration. Interventions to reduce IPV victimisation might help prevent IPV perpetration by women. Data collection on mental disorder and IPV perpetration should be strengthened in future population-based surveys, with greater consistency of data collection across surveys, as only four studies were able to contribute to the meta-mediation analysis.

Review
Adolescent dating and relationship violence (DRV) is widespread and associated with increased risk of subsequent poor mental health outcomes and partner violence. Shifting social norms (i.e., descriptive norms of perceived behavior and injunctive norms of acceptable behavior among a reference group of important others) may be important for reducing DRV. However, few DRV studies assess norms, measurement varies, and evidence on measure quality is diffuse. We aimed to map and assess how studies examining DRV measured social norms concerning DRV and gender. We conducted a systematic review of DRV literature reporting on the use and validity of such measures among participants aged 10-18 years. Searches included English peer-reviewed and grey literature identified via nine databases; Google Scholar; organization websites; reference checking; known studies; and expert requests. We identified 24 eligible studies from the Americas ( = 15), Africa ( = 4), and Europe ( = 5) using 40 eligible measures of DRV norms (descriptive: = 19; injunctive: = 14) and gender norms (descriptive: = 1; injunctive: = 6). No measure was shared across studies. Most measures were significantly associated with DRV outcomes and most had a defined reference group. Other evidence of quality was mixed. DRV norms measures sometimes specified heterosexual relationships but rarely separated norms governing DRV perpetrated by girls and boys. None specified sexual-minority relationships. Gender norms measures tended to focus on violence, but missed broader gendered expectations underpinning DRV. Future research should develop valid, reliable DRV norms and gender norms measures, and assess whether interventions' impact on norms mediates impact on DRV.

Review
BACKGROUND
In recent years, the prevalence of childhood emotional abuse has surpassed other forms of maltreatment. Childhood verbal abuse (CVA) is a key attribute of emotional abuse, yet CVA is not recognized as its own form of maltreatment and thus, has not received adequate attention. Clear terminology, definitions, and measures are needed to aid in assessing the occurrence and impact of CVA for its recognition and prevention.
OBJECTIVE
We aim to synthesize the evidence on the terms, definitions, and measurements of CVA and identify outcomes associated with CVA.
PARTICIPANTS AND SETTING
A systematic review focused on adult perpetration of CVA among children and adolescents using clinical, community-based, and population-based samples.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed and four databases were utilized in May 2022: PsycINFO, MEDLINE, EMBASE, and ProQuest. A total of 149 quantitative and 17 qualitative studies were identified.
RESULTS
Across studies reviewed, the most common perpetrators of CVA were parents, mothers, and teachers. Definitional themes for CVA included negative speech volume, tone, and speech content, and their immediate impact. The most frequent measures cited were Adverse Childhood Experiences Study (ACE) Questionnaire and the Conflict Tactics Scale (CTS); 50 % used self-created measures. CVA was associated with a range of internalizing and externalizing outcomes across the lifespan.
CONCLUSIONS
Recognizing CVA as a form of maltreatment will be a starting point for its identification and prevention. Primary prevention of CVA using trauma-informed approaches must include adult training on the importance of safety, support, and nurturance during verbal communication with children.

Review
Efforts to prevent or respond to intimate partner violence (IPV) and violence against children (VAC) are still disparate worldwide, despite increasing evidence of intersections across these forms of violence. We conducted a systematic review to explore interventions that prevent or respond to IPV and VAC by parents or caregivers, aiming to identify common intervention components and mechanisms that lead to a reduction in IPV and VAC. 30 unique interventions from 16 countries were identified, with 20 targeting both IPV and VAC. Key mechanisms for reducing IPV and VAC in primary prevention interventions included improved communication, conflict resolution, reflection on harmful gender norms, and awareness of the adverse consequences of IPV and VAC on children. Therapeutic programmes for women and children who were exposed to IPV facilitated engagement with IPV-related trauma, increased awareness of the effects of IPV, and promoted avoidance of unhealthy relationships. Evidence gaps in low-income and middle-income countries involved adolescent interventions, post-abuse interventions for women and children, and interventions addressing both prevention and response to IPV and VAC. Our findings strengthen evidence in support of efforts to address IPV and VAC through coordinated prevention and response programmes. However, response interventions for both IPV and VAC are rare and predominantly implemented in high-income countries. Although therapeutic programmes for parents, caregivers, and children in high-income countries are promising, their feasibility in low-income and middle-income countries remains uncertain. Despite this uncertainty, there is potential to improve the use of health services to address IPV and VAC together.

BACKGROUND
Violence against children (VAC) is a global public health issue. In the context of limited resources, the United Nations Development Programme has coined the concept of a Sustainable Development Goals (SDG) accelerator for preventing and responding to VAC. An 'accelerator' is a provision that simultaneously leads to progress across multiple SDGs targets and goals.
OBJECTIVES
This systematic review synthesizes the literature on violence prevention evaluation studies using robust methods according to the SDG accelerator framework for children aged 0-18 in Western Europe and Central and West Africa. It also provides a lens for analyzing research inequities between the global North and South, examining the challenges and differences undermining knowledge production across regions, particularly in research output.
METHOD
We systematically searched 30 electronic databases and grey literature in English and French. The quality of included studies was assessed using the Cochrane Risk of Bias tool.
RESULTS
Nine evaluation studies related to four SDG goals and ten targets were included in the analysis. As a result, no intervention was identified as an accelerator for children in West and Central Africa. In contrast, three promising interventions were identified as accelerators in Western Europe. Two school-based interventions reduce bullying, depression, and substance abuse and improve psychological well-being; and one home-based intervention reduces child abuse, the severity of neglect, and mental health problems and improves school attendance. Moreover, this review also uncovered a lack of research from the Global South that points to serious disadvantages for authors and institutions and global violence prevention efforts, as it hinders the flow of knowledge and innovative practices.
CONCLUSIONS
The results highlight the need for future VAC prevention trials to integrate the SDG accelerators concept further. Additionally, more effort should be made to support scholars in the global South to address knowledge inequities and to enhance understanding of how accelerators work in different field settings and conditions. This effort will ensure that interventions accelerate SDG goals and impact the world's most vulnerable children.

Meta-Analysis
BACKGROUND/AIMS
Domestic violence (DV) encompasses a series of abusive behaviors, perpetrated in a family environment, against individuals of all ages and genders. Injuries to the head, neck, and face are frequent findings among victims of abuse, negatively impacting their quality of life. Although oral and maxillofacial injuries (OMFI) and traumatic dental injuries (TDI) are commonly diagnosed among DV victims, their prevalence is still unknown. This systematic review was aimed to assess the prevalence of OMFI and TDI among victims of DV.
METHODS
The protocol of the review was registered in PROSPERO (CRD42023424235). Literature searches were performed in eight electronic databases, up to August 7th, 2023. Observational studies published in the Latin-roman alphabet and reporting the prevalence of OMFI and/or TDI were included. The Joanna Briggs Institute's critical appraisal tool, checklist for prevalence studies, was used for quality assessment. Results were presented as qualitative and quantitative syntheses.
RESULTS
Seventeen studies, totaling 12,375 victims of domestic violence, were included. Meta-analyses showed an overall prevalence of 29% (95% CI: 15%-48%, I = 99%) and 4% (95% CI: 1%-10%, I = 98%) for OMFI and TDI, respectively. Higher pooled prevalence for OMFI (41%, 95% CI: 13%-46%, I = 99%) was demonstrated in samples with only women. OMFI was less prevalent (20%) among DV victims under 18, while TDI was lower among adults (1%). Hospital samples presented higher pooled prevalence of OMFI (32%), and forensic data from fatal victims presented higher prevalence of TDI (8%).
CONCLUSION
The overall prevalence of OMFI and TDI in DV victims was 29% and 4%, respectively. Women victims of DV presented higher rates of OFMI (41%) and TDI (6%).

Review
OBJECTIVE
To explore the technology-based tools available for supporting the identification of victims of domestic abuse and modern slavery in remote services and consider the benefits and challenges posed by the existing tools.
METHODS
We searched six academic databases. Studies were considered for inclusion if they were published in English between 2000 and 2023. The QuADS quality appraisal tool was used to assess the methodological quality of included studies. A narrative synthesis was conducted using the convergent integrated approach.
RESULTS
Twenty-four studies were included, of which two were professional guidelines; each reported on a distinct technology-based tool for remote services. All tools related to domestic abuse and 21 focused on screening for intimate partner violence among young and mid-life women (18-65) in high-income countries. The review did not identify tools that support the identification of victims of modern slavery. We identified eight common themes of tool strengths, highlighting that the remote approach to screening was practical, acceptable to victims, and, in some circumstances, elicited better outcomes than face-to-face approaches. Five themes pointed to tool challenges, such as concerns around privacy and safety, and the inability of computerised tools to provide empathy and emotional support.
CONCLUSIONS
Available technology-based tools may support the identification of victims of domestic abuse by health and social care practitioners in remote services. However, it is important to be mindful of the limitations of such tools and the effects individuals' screening preferences can have on outcomes. Future research should focus on developing tools to support the identification of victims of modern slavery, as well as empirically validating tools for screening during remote consultations.

Meta-Analysis Review
Child abuse is an important factor for Internet addiction. Despite numerous researches had observed there was a positive correlation between child abuse and Internet addiction, the strength of this association differed considerably in the previous studies. This study aims to obtain reliable estimates for effect sizes and investigate the potential moderator of the association between child abuse and Internet addiction. Thirty-one studies reported the association between child abuse and Internet addiction (273 effect sizes and 55,585 participants) through a systematic literature search. Based on Preferred Reporting Items for Systematic Review and Meta-Analysis approach, a three-level model was employed to conduct a three-level meta-analysis. The current meta-analysis found that child abuse was significantly positively correlated with Internet addiction. Besides, the study found that the type of child abuse and publication year had significant moderating effects on the association between child abuse and Internet addiction. This study suggested child abuse was a risk factor for Internet addiction. Moreover, child abuse is an essential factor should be considered when strengthening interventions for individuals' Internet addiction.
