Improving measurement of child abuse and neglect: A systematic review and analysis of national prevalence studies

Specific effects of cumulative childhood trauma on suicidality among youths

BACKGROUND

Suicidality was very high among individuals who suffered from childhood trauma. The distribution of cumulative childhood trauma among youths remains unclear, as well as the specific effects of cumulative childhood trauma on suicidality. This study attempted to explore the distribution of cumulative childhood trauma and examine the specific effects of cumulative childhood trauma on suicidality.

METHODS

A cross-sectional design was employed in this study, with 117,769 college students recruited from 63 universities in Jilin Province, China. All variables were measured by corresponding self-report questionnaires. The Venn diagram was used to represent the distribution of single and cumulative childhood trauma. ANOVA and chi-square tests were conducted to identify the high-risk suicide groups. Multiple linear regression analysis was performed to examine risk factors for suicidality for overlapping subtypes.

RESULTS

27,671 (23.5%) participants reported suffering from childhood trauma, of which 49.5% were male (Mage = 19.59, SD = 1.76). The "physical neglect" group accounted for the largest proportion (31.5%). Suicidality was the highest in the "overlap of childhood neglect, emotional abuse, and physical abuse" group (2.0%). Depression, obsessive-compulsive disorder, and post-traumatic stress disorder were common risk factors for suicidality.

LIMITATIONS

This study was limited by cross-sectional studies and self-report bias.

CONCLUSIONS

The childhood trauma subtype group with the largest proportion was not necessarily the highest suicidality. Both the largest group and the highest-risk suicide group require special attention to their respective risk factors.

Prevention of child sexual abuse in the United States: Scoping review of United States legislative policies

BACKGROUND

States in the United States (US) have passed and enacted legislation for the purpose of preventing child sexual abuse (CSA) since 2000, but it is unknown whether these legislative policies reduce adult-perpetrated CSA.

OBJECTIVE

Review the literature from 2000 to 2023 to understand which US CSA prevention policies have been evaluated, the effectiveness of these policies, study populations, and barriers and facilitators associated with the implementation of CSA prevention policies.

METHODS

The study protocol was published prior to undertaking the review: PMC10603531. The review follows Joanna Briggs Institute methodology and is reported according to the PRISMA-ScR Checklist. We searched 27 databases, hand searched reference lists of included studies, and sent notice via listserv to other researchers in the field. Articles were included if the content focused on CSA prevention policies and the effects. No limits to methodology were applied. Methodological rigor was assessed.

RESULTS

2209 potentially relevant articles were identified; 20 articles advanced to full-text review, three satisfied the inclusion criteria. Three eligible studies focused on CSA prevention education policies, while the other focused on mandated reporting policies. Effects of these policies were mixed in relation to CSA reporting and substantiation rates. No study considered child demographics.

CONCLUSIONS

Despite decades of legislative action for CSA prevention across the US, only a few studies have assessed the effects of these policies. These findings highlight the need for additional research to ensure that CSA prevention policies such as CSA prevention education in schools and mandated reporting practices are working as intended.

Lifetime victimization experiences, depressiveness, suicidality, and feelings of loneliness in youth in care

BACKGROUND

Research has demonstrated the damaging effects of poly-victimization on the mental health of children and adolescents. However, few studies have been conducted in high-risk youth in care (Y-IC) samples.

OBJECTIVE

The study examines the frequency of lifetime victimization and the association of poly-victimization and victimization types on depressiveness, suicidality, and feelings of loneliness among Y-IC.

PARTICIPANTS AND SETTING

164 participants aged 14 and 21 years (M = 17.39, SD = 1.95), who live in family-based care or residential care.

METHODS

The Juvenile Victimization Questionnaire (JVQ) was used to assess lifetime victimization. The Patient Health Questionnaire (PHQ-9), and the Loneliness Scale-SOEP (LS-S) to measure depressiveness, suicidality, and loneliness. Hierarchical regression models were calculated.

RESULTS

Participants reported on average 12.66 (SD = 6.58) victimization experiences. The female and diverse gender groups reported higher rates of victimization, loneliness, depressiveness, and suicidality than the males. Participants in residential care reported more victimizations and stronger feelings of loneliness than those in family-based care. Poly-victimization was not associated with any of these internalizing symptoms but peer victimization was significantly associated with depressiveness (β = 0.23, p = .002) and loneliness (β = 0.22, p = .006), sexual victimization with depressiveness (β = 0.22, p = .004).

CONCLUSION

Y-IC show high levels of victimization and internalizing symptoms, with higher burden on girls and youth living in residential care. Findings underscore the relevance of social exclusion experiences among peers within Y-IC. Interventions should address multiple forms of victimization, with a special focus on sexual and peer victimization.

Unraveling the Concept of Childhood Adversity in Psychosis Research: A Systematic Review

BACKGROUND

During the last decades, an abundance of studies has investigated childhood adversity in relation to psychosis. This systematic review critically examines the methodologies employed to investigate childhood adversity in psychosis over the past decade, including operational definitions, measurement tools and characteristics, and psychometric properties of instruments used in these studies.

STUDY DESIGN

This systematic review followed the PRISMA guidelines (registration number CRD42022307096), and the search used the following electronic databases: PsychINFO, SCOPUS, Web of Science, African Index Medicus (AIM), LILACS, CINAHL, EMBASE, and MEDLINE. The search included variations and combinations of the terms targeting childhood adversity and psychosis.

STUDY RESULTS

Out of 585 identified studies published between 2010 and 2023, 341 employed a validated instrument to investigate childhood adversity. Our findings show "childhood trauma" being the most frequently examined construct, followed by "child maltreatment" or "child abuse." The short version of the Childhood Trauma Questionnaire was the dominant instrument. Physical abuse, emotional abuse, and sexual abuse were most frequently investigated, and indeed the field appears generally to focus on child abuse and neglect over other adversities. Significant psychometric heterogeneity was observed in the selection and summarization of instrument items, with only 59% of studies documenting original psychometric validation and 22% reporting reliability in their datasets.

CONCLUSION

This review highlights substantial methodological heterogeneity in the field, pointing out biases in the research on childhood adversity and psychosis. These findings underline the need for standardized definitions and high-quality measurement tools to enhance the validity of future research in this area.

Early identification and awareness of child abuse and neglect among physicians and teachers

BACKGROUND

Child abuse and neglect (CAN) causes enormous suffering for those affected.

OBJECTIVE

The study investigated the current state of knowledge concerning the recognition of CAN and protocols for suspected cases amongst physicians and teachers.

METHODS

In a pilot study conducted in Mecklenburg-Western Pomerania from May 2020 to June 2021, we invited teachers and physicians working with children to complete an online questionnaire containing mainly multiple-choice-questions.

RESULTS

In total, 45 physicians and 57 teachers responded. Altogether, 84% of physicians and 44% of teachers were aware of cases in which CAN had occurred in the context of their professional activity. Further, 31% of physicians and 23% of teachers stated that specific instructions on CAN did not exist in their professional institution or that they were not aware of them. All physicians and 98% of teachers were in favor of mandatory training on CAN for pediatric residents and trainee teachers. Although 13% of physicians and 49% of teachers considered a discussion of a suspected case of CAN to constitute a breach of confidentiality, 87% of physicians and 60% of teachers stated that they would discuss a suspected case with colleagues.

CONCLUSION

Despite the fact that a large proportion of respondents had already been confronted with suspected cases of CAN, further guidelines for reporting procedures and training seem necessary. There is still uncertainty in both professions on dealing with cases of suspected CAN.

The burden of prenatal and early life maternal substance use among children at risk of maltreatment: A systematic review

ISSUES

Although maternal substance use is a known risk factor for child maltreatment, evidence on the scale of substance use is needed to inform prevention responses. This systematic review synthesised prevalence estimates of maternal substance use during pregnancy and early life among children at risk of maltreatment. Ovid, Pubmed, CINAHL, PsychInfo and ProQuest databases were searched. We included observational studies that sampled children at risk of maltreatment in high-income countries and reported information on maternal substance use during pregnancy and/or the child's first year of life. We extracted study characteristics and data to calculate prevalence, assessed risk of bias and conducted a narrative synthesis; there were insufficient comparable populations or outcomes to quantitatively synthesise results.

KEY FINDINGS

Thirty five of 14,084 titles were included. Fifteen studies had adequately sized and representative samples to estimate prevalence. Maternal substance use prevalence ranged from 2.4% to 40.6%. Maternal substance use was highest among infants referred to child protection at birth (40.6%) and children in out-of-home care (10.4% to 37.2%). Prevalence was higher when studies defined substance use more broadly and when maternal substance use was ascertained from both child and mother records.

IMPLICATIONS

Supportive, coordinated responses to maternal substance use are needed from health and child protection services, spanning alcohol and other drug treatment, antenatal and postnatal care.

CONCLUSIONS

Prenatal and early life maternal substance use is common among child maltreatment populations, particularly among younger children and those with more serious maltreatment.

Global Prevalence of Childhood Exposure to Physical Violence within Domestic and Family Relationships in the General Population: A Systematic Review and Proportional Meta-Analysis

Efforts to identify and prevent childhood exposure to physical violence within domestic and family relationships must be underpinned by reliable prevalence estimates to ensure the appropriate allocation of resources and benchmarks for assessing intervention efficacy. We conducted a systematic review and meta-analysis of the global prevalence of childhood exposure to physical domestic and family violence separately as a victim or witness. Searches were conducted in Criminal Justice Abstracts, Embase, Scopus, PubMed, PsychInfo, and Google Scholar. Studies were included if they were peer-reviewed, published in English, had a representative sample, unweighted estimates, and were published between January 2010 and December 2022. One-hundred-and-sixteen studies comprising 56 independent samples were retained. Proportional meta-analysis was conducted to calculate the pooled prevalence for each exposure. Pooled prevalence estimates were also stratified by region and sex. The global pooled prevalence of childhood exposure to physical domestic and family violence as a victim or witness was 17.3% and 16.5%, respectively. Prevalence estimates were highest in West Asia and Africa (victim = 42.8%; witness = 38.3%) and lowest for the Developed Asia Pacific region (victim = 3.7%; witness = 5.4%). Males were 25% more likely than females to be the victim of physical domestic and family violence during childhood, while both were equally likely to have witnessed it. These findings suggest that childhood exposure to domestic and family violence is relatively common, affecting around one-in-six people by 18 years of age globally. Regional variations in prevalence estimates may reflect underlying economic conditions, cultural norms, and service availability.

Prevalence of Diverse Genders and Sexualities in Australia and Associations With Five Forms of Child Maltreatment and Multi-type Maltreatment

This study presents the most comprehensive national prevalence estimates of diverse gender and sexuality identities in Australians, and the associations with five separate types of child maltreatment and their overlap (multi-type maltreatment). Using Australian Child Maltreatment Study (ACMS) data (N = 8503), 9.5% of participants identified with a diverse sexuality and .9% with a diverse gender. Diverse identities were more prevalent in the youth cohort, with 17.7% of 16-24 years olds identifying with a diverse sexuality and 2.3% with a diverse gender. Gender and sexuality diversity also intersect - for example, with women (aged 16-24 and 25-44) more likely than men to identify as bisexual. The prevalence of physical abuse, sexual abuse, emotional abuse, neglect and exposure to domestic violence was very high for those with diverse sexuality and/or gender identities. Maltreatment was most prevalent for participants in the youth cohort with diverse gender identities (90.5% experiencing some form of child maltreatment; 77% multi-type maltreatment) or diverse sexualities (85.3% reporting any child maltreatment; 64.3% multi-type maltreatment). The strong association found between child maltreatment and diverse sexuality and gender identities is critical for understanding the social and mental health vulnerabilities of these groups, and informing services needed to support them.

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.

Measuring Violence Against Children: A COSMIN Systematic Review of the Psychometric and Administrative Properties of Adult Retrospective Self-report Instruments on Child Abuse and Neglect

Valid, meaningful, and reliable adult retrospective measures of violence against children (VAC) are essential for establishing the prevalence, risk factors, and long-term effects of VAC. We aim to summarize the available evidence on the psychometric properties of adult retrospective VAC measures and to provide evidence-based recommendations for appropriate measure selection. We searched six electronic databases and gray literature for studies that report on the development, content validity, or psychometric properties of adult retrospective child abuse and neglect measures for this review (PROSPERO: CRD4201706). We used the 2018 Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria to evaluate each included study and measure. We assessed if measures included questions on frequency or severity, the perpetrator, or the location of the violence, and noted the administrative practicalities for each instrument such as length, readability, available translations, and cost to access. We identified 288 studies and 77 measures. The quality of evidence ranged from "low" to "high," depending on the measure and the psychometric properties assessed. The measures with the most robust evidence available across multiple contexts are the: ACE and ACE-IQ; FBQ and FBQ-U; CTQ and CTQ-SF; and ICAST-R. This review shows the strengths and weaknesses of retrospective VAC measures. The substantial evidence presented in this review can be used by researchers to make psychometrically sound decisions for measurement selection which should be supported by extensive piloting and adaptation to the respective local context.

COVID-19 and Caregiver Risk Factors for Child Maltreatment: The Pandemic in Review

The COVID-19 pandemic has fostered an environment for increased risk of child maltreatment (CM) as families experience increased psychosocial and financial burdens and spend unprecedented amounts of time together in the home. This narrative review aimed to summarize empirical findings on existing or new pandemic-related risk factors among caregivers. A combination of search terms related to CM and COVID-19 were used to identify articles published within five databases between February 2020 and July 2022. Literature searches produced 113 articles, of which 26 published across 12 countries met inclusion criteria. Four previously well-established risk factors for CM perpetration continued to persist during the pandemic, including stress, parental mental health, financial concerns, and parental substance use. Of note, inconsistent definitions and measures were used to capture these risk factors. Several additional emerging and understudied risk factors were also identified among limited articles, such as food insecurity and parental education. Findings emphasize the ongoing need for evidence-based interventions to address CM risk during the pandemic, including parent training programs. However, consolidated measures and consistent conceptualization of risk factors are needed to advance the study of CM. Going forward, practitioners and researchers should (a) strengthen the identification process for families at greatest risk for CM, and particularly those vulnerable to pandemic-related stressors; and (b) augment delivery of CM prevention strategies and evidence-based programs to fit the pandemic context.

Child sexual abuse by different classes and types of perpetrator: Prevalence and trends from an Australian national survey

BACKGROUND

Little evidence exists about the prevalence of child sexual abuse (CSA) inflicted by different relational classes of perpetrators (e.g., parents; institutional adults; adolescents), and by individual types of perpetrators (e.g., fathers and male relatives; male teachers and male clergy; known and unknown adolescents).

OBJECTIVE

To generate evidence of the prevalence of CSA by different perpetrators, and trends by victim gender and age group.

PARTICIPANTS AND SETTING

The Australian Child Maltreatment Study collected information about CSA victimisation from a nationally-representative sample of 8503 individuals aged 16 and over.

METHODS

We analysed data about 42 perpetrator types, collapsed into eight classes. We generated national prevalence estimates of CSA inflicted by each perpetrator class and individual perpetrator type, and compared results by victim gender and age group.

RESULTS

Australian CSA prevalence was 28.5%, with the following prevalence by perpetrator classes: other known adolescents (non-romantic): 10.0%; parents/caregivers in the home: 7.8%; other known adults: 7.5%; unknown adults: 4.9%; adolescents (current/former romantic partners): 2.5%; institutional caregivers: 2.0%; siblings: 1.6%; unknown adolescents: 1.4%. Women experienced more CSA by all perpetrator classes except institutional caregivers. Age group comparison showed significant declines in CSA by parents/caregivers, and other known adults; and increases in CSA by adolescents (current/former romantic partners). Individual perpetrator type comparison showed declines in CSA by fathers, male relatives living in the home, non-resident male relatives, and other known male adults; and increases in CSA by known male adolescents, current boyfriends, and former boyfriends.

CONCLUSIONS

CSA by adults has declined, indicating positive impacts of prevention efforts. However, CSA by adolescents has increased. Further declines in CSA by adults are required and possible. Targeted prevention of CSA by adolescents must be prioritised.

Contamination in Observational Research on Child Maltreatment: A Conceptual and Empirical Review With Implications for Future Research

Contamination is a methodological phenomenon occurring in child maltreatment research when individuals in an established comparison condition have, in reality, been exposed to maltreatment during childhood. The current paper: (1) provides a conceptual and methodological introduction to contamination in child maltreatment research, (2) reviews the empirical literature demonstrating that the presence of contamination biases causal estimates in both prospective and retrospective cohort studies of child maltreatment effects, (3) outlines a dual measurement strategy for how child maltreatment researchers can address contamination, and (4) describes modern statistical methods for generating causal estimates in child maltreatment research after contamination is controlled. Our goal is to introduce the issue of contamination to researchers examining the effects of child maltreatment in an effort to improve the precision and replication of causal estimates that ultimately inform scientific and clinical decision-making as well as public policy.

Prevalence of violence against children in the United Kingdom: A systematic review and meta-analysis

BACKGROUND

Violence against children can have extensive, long-term, and far-reaching adverse impacts on survivors and society. There is currently little consensus in the United Kingdom around the prevalence of violence against children: maltreatment, intimate partner violence, sexual violence, bullying, and community violence, and most existing studies focus on only a single or a few forms of violence. This study aims to produce data to highlight the current magnitude of the problem in the UK, to inform policy, drive action and allow for monitoring of progress over time.

OBJECTIVE

To produce weighted prevalence estimates by violence type, as well as gender and age sub-categories, to give as full a picture as possible of the current prevalence of violence against children in the UK.

PARTICIPANTS AND SETTING

The prevalence of violence against children from 23 self-report studies conducted in the United Kingdom was gathered through a systematic review.

METHODS

Databases were searched from inception to 24th June 2022. Studies were reviewed systematically for appropriate data and meta-analyses were conducted to give pooled prevalence data based on a quality effects model.

RESULTS

The most prevalent self-reported experience of childhood violence was community violence at 27.33 % (95 % CI [9.84, 48.97]). Prevalence of bullying was also high at 22.75 % (95 % CI [13.25, 33.86]). The most prevalent forms of child maltreatment were domestic violence exposure at 11.9 % (95 % CI [6.34, 18.84]) and emotional maltreatment at 11.84 % (95 % CI [5.58, 19.89]).

CONCLUSION

National child maltreatment surveys are needed in the UK, using a comprehensive and conceptually robust approach, and valid and reliable instruments, to provide data for researchers and policymakers on the prevalence of all types of violence against children including exposure to multiple types. This allows monitoring of trends over time, can inform strategies for prevention, and can enable monitoring of future progress in reducing violence against children and its associated health and economic burden.

Effectiveness of child sexual abuse prevention programs on knowledge acquisition: A meta-analytical study

BACKGROUND

Child sexual abuse (CSA) is a type of maltreatment considered a global health problem. CSA is a traumatic experience with important consequences for the victim's health. It is essential to report the effectiveness of CSA prevention programs to offer society useful tools to combat this abuse.

OBJECTIVE

We aimed to study the effectiveness of CSA prevention programs on the knowledge acquisition based on comparing pre- and post-treatment changes, and also if their effectiveness is related to program-related and methodological variables.

PARTICIPANTS AND SETTINGS

Standardised mean change (with studies that report pre-post program measures) of the effectiveness of CSA prevention programs published between 2014 and 2021 was carried out.

METHODS

The general effectiveness of these programs and whether the results were influenced by program-related variables (the duration, the target population, participants' age, or the type of intervention) or by methodology-related factors (the agent who taught them, the geographical area where they were carried out or the way the programs were evaluated) were analysed. A total of 43 samples analysing knowledge about CSA as a dependent variable were included.

RESULTS

The results reported a combined effect size considered large (dMR = -0.96, 95 % CI [-1.10, -0.82], p < .001). High inter-study heterogeneity was observed in the meta-analysis, although only the geographic area where the studies were conducted appears as a significant moderator.

CONCLUSIONS

In conclusion, the prevention programs included in this analysis significantly improved the participants' knowledge acquisition.

Different Instruments, Same Content? A Systematic Comparison of Child Maltreatment and Harsh Parenting Instruments

Child maltreatment and harsh parenting both include harmful actions by parents toward children that are physical (e.g., spanking, slapping) or emotional (e.g., threatening, yelling). The distinction between these two constructs, in meaning and measurement, is often unclear, leading to inconsistent research and policy. This study systematically identified, reviewed, and compared parent-reported child maltreatment (N = 7) and harsh parenting (N = 18) instruments. The overlap in parenting behaviors was 73%. All physical behaviors that were measured in harsh parenting instruments (e.g., spanking, beating up) were also measured in child maltreatment instruments. Unique physical behaviors measured in maltreatment instruments include twisting body parts and choking. All emotional behaviors in maltreatment instruments were included in harsh parenting instruments, and vice versa. Our findings suggest similar, but not identical, operationalizations of child maltreatment and harsh parenting. Our findings can help guide discussions on definitions, operationalizations, and their consequences for research on violence against children.

Validity and reliability of the 10-Item Adverse Childhood Experiences Questionnaire (ACE-10) among adolescents in the child welfare system

Introduction

Multiple evidence suggests that the vast majority of children in the Child Welfare System (CWS) are victims of early, chronic, and multiple adverse childhood experiences. However, the 10-item version of the Adverse Childhood Experiences Questionnaire (ACE-10) has never been tested in such a particularly vulnerable population as adolescents living in the CWS. We aimed to assess the psychometric properties of the ACE-10 in a community sample of 240 Hungarian adolescents placed in family style group care (FGC) setting.

Methods

Demographic data, the 10-item version of the Adverse Childhood Experiences Questionnaire (ACE-10), the Strengths and Difficulties Questionnaire (SDQ), and the HBSC Bullying Measure were used.

Results

Our results showed acceptable internal consistency (α = 0.701) and item-total correlations (rpb = 0.25-0.65, p < 0.001). However, our results also reflect that item 6 ("Parental separation/divorce") is weakly correlated with both the cumulative ACE score and the rest of the questionnaire items. When item 6 is removed, the 9-item version of the ACE produces more favorable consistency results (α = 0.729). Strong and significant associations of the cumulative ACE score with emotional and behavioral symptoms and bully victimization confirm the concurrent criterion validity of both versions of the instrument.

Discussion

Our findings suggest that ACE-9 and ACE-10 are viable screening tools for adverse childhood experiences in the CWS contributing to the advancement of trauma-informed care. We recommend considering the use of either the 9-item or the 10- item version in the light of the characteristics of the surveyed population. The implications and limitations are discussed.

[Comparison of Self-Reported Childhood Maltreatment Between East and West Germany]

OBJECTIVE

The socioecological model emphasize the relevance of political, cultural and economic socialization effects for the prevalence of childhood maltreatment, which are analyzed by comparing child maltreatment between East and West German subjects who came of age before the fall of the Berlin Wall.

METHODS

Using an online survey, a representative general population sample with respect to age, gender distribution and income was assessed regarding child maltreatment and current psychological distress using standardized self-report instruments.

RESULTS

Of 507 study participants, 22,5% reported being born and socialized in East Germany. They reported significantly less emotional abuse than the 77,5% who grew up in the FRG. The East and West German subjects did not differ in any other form of abuse.

CONCLUSION

Our findings underline the importance of socialization and enculturation effects on memory, which should be considered when interpreting the results.

PROTOCOL: Psychometric properties of instruments for measuring elder abuse and neglect in community and institutional settings: A systematic review

Background

The psychometric properties of elder abuse measurement instruments have not been well-studied. Poor psychometric properties of elder abuse measurement instruments may contribute to the inconsistency of elder abuse prevalence estimates and uncertainty about the magnitude of the problem at the national, regional, and global levels.

Objectives

The present review will utilise the COSMIN taxonomy on the quality of outcome measures to identify and review the instruments used in measuring elder abuse, assess the instrument's measurement properties, and identify the definitions of elder abuse and abuse subtypes measured by the instrument.

Search Methods

Searches will be conducted in the following online databases: Ageline, ASSIA, CINAHL, CNKI, EMBASE, Google Scholar, LILACS, Proquest Dissertation & Theses Global, PsycINFO, PubMed, SciELO, Scopus, Sociological Abstract and WHO Index Medicus. Relevant studies will also be identified by searching the grey literature from several resources such as OpenAIRE, BASE, OISter and Age Concern NZPotential studies by searching the references of related reviews. We will contact experts who have conducted similar work or are currently conducting ongoing studies. Enquiries will also be sent to the relevant authors if any important data is missing, incomplete or unclear.

Selection Criteria

All quantitative, qualitative (that address face and content validity), and mixed-method empirical studies published in peer-reviewed journals or the grey literature will be included in this review. Studies will be included if they are primary studies that (1) evaluate one or more psychometric properties; (2) contain information on instrument development, or (3) perform content validity of the instruments designed to measure elder abuse in the community or institutional settings. Studies should describe at least one of the psychometric properties, such as reliability, validity and responsiveness. Study participants represent the population of interest, including males and females aged 60 or older in community or institutional settings (i.e., nursing homes, long-term care facilities, assisted living, residential care institutions, and residential facilities).

Data Collection and Analysis

Screening of titles, abstracts, and full texts of the selected studies will be evaluated based on the preset inclusion criteria by two reviewers. Two reviewers will be assessing the quality appraisal of each study using the COSMIN Risk of Bias checklist and the overall quality of evidence of each psychometric property of the instrument against the updated criteria of good measurement properties. Any dispute between the two reviewers will be resolved through discussions or consensus with a third reviewer. The overall quality of the measurement instrument will be graded using a modified GRADE approach. Data extraction will be performed using the data extraction forms adapted from the COSMIN Guideline for Systematic Reviews of Outcome Measurement Instruments. The information includes the characteristic of included instruments (name, adaptation, language used, translation and country of origin), characteristics of the tested population, psychometric properties listed in the COSMIN criteria, including details on the instrument development, content validity, structural validity, internal consistency, cross-cultural validity/measurement invariance, reliability, measurement error, criterion validity, hypotheses testing for construct validity, responsiveness and interoperability. We will perform a meta-analysis to pool psychometric properties parameters (where possible) or summarise qualitatively.

Derivation of probable child maltreatment indicators using prospectively recorded information between 5 months and 17 years in a longitudinal cohort of Canadian children

BACKGROUND

Both prospective and retrospective measures of child maltreatment predict mental and physical health problems, despite their weak concordance. Research remains largely based on retrospective reports spanning the entire childhood due to a scarcity of prospectively completed measures targeting maltreatment specifically.

OBJECTIVE

We developed a prospective index of child maltreatment in the Québec Longitudinal Study of Child Development (QLSCD) using prospective information collected from ages 5 months to 17 years and examined its concordance with retrospective maltreatment.

PARTICIPANTS AND SETTING

The QLSCD is an ongoing population-based cohort that includes 2,120 participants born from 1997-1998 in the Canadian Province of Quebec.

METHODS

As the QLSCD did not have maltreatment as a focal variable, we screened 29,600 items completed by multiple informants (mothers, children, teachers, home observations) across 14 measurement points (5 months-17 years). Items that could reflect maltreatment were first extracted. Indicators were derived across preschool, school-age and adolescence periods and by the end of childhood and adolescence, including presence (yes/no), chronicity (re-occurrence), extent of exposure and cumulative maltreatment. Two maltreatment experts reviewed these items for inclusion and determined cut-offs for possible child maltreatment (n=251 items). Retrospective maltreatment was self-reported at 23 years.

RESULTS

Across all developmental periods, the presence of maltreatment was as follows: physical abuse (16.3-21.8%), psychological abuse (3.3-21.9%), emotional neglect (20.4-21.6%), physical neglect (15.0-22.3%), supervisory neglect (25.8-44.9%), family violence (4.1-11.2%) and sexual abuse (9.5% in adolescence only). The degree of concordance between prospective and retrospective reports for each type of maltreatment was weak (.038-.110), yet significant (ps<.01), except for emotional neglect (p=.148).

CONCLUSIONS

In addition to the many future research opportunities offered by these prospective indicators of maltreatment, this study offers a roadmap to researchers wishing to undertake a similar task.

Measuring Violence Against Children: A COSMIN Systematic Review of the Psychometric Properties of Child and Adolescent Self-Report Measures

Research on violence against children (VAC) requires meaningful, valid, and reliable self-report by children. Many instruments have been used globally and decisions to select suitable measures are complex. This review identifies child and adolescent self-report measures that are most likely to yield valid, reliable, and comparable data in this field. A systematic review (PROSPERO: CRD4201706) was conducted using the 2018 Consensus-based Standards for the selection of health Measurement Instrument (COSMIN) criteria. Six electronic databases and gray literature were searched. Manuscripts published in English and describing the development and psychometric qualities of child/adolescent self-report instruments were included. Thirty-nine original instruments and 13 adaptations were identified in 124 studies. The quality of evidence ranged from "very low" to "high" depending on the measure and the psychometric properties assessed. Most measures were not widely used, and some have been applied in many settings despite limited evidence of their psychometric rigor. Few studies assessed content validity, particularly with children. The ACE, CTQ, CTS-PC, CECA, ICAST, and JVQ have the best psychometric properties. An overview of items measuring frequency, onset, duration, perpetrators, and locations is provided as well as an assessment of the practicalities for administration to help researchers select the instrument best suited for their research questions. This comprehensive review shows the strengths and weaknesses of VAC research instruments. Six measures that have sufficient psychometric properties are recommended for use in research, with the caveat that extensive piloting is carried out to ensure sufficient content validity for the local context and population.

Emotional neglect and parents' adverse childhood events

INTRODUCTION

Emotional neglect means that the child's emotional and developmental needs are not fulfilled by the parents or other caregivers. Adverse childhood events (ACEs) are a risk factor for mental health problems and impaired parenting skills. The objective here was to examine whether parents' ACEs increase the child's risk of experiencing emotional neglect.

METHODS

The participants in the present study were members of the Northern Finland Birth Cohort 1986 (NFBC1986). Emotional neglect experiences were measured in 190 members of this cohort by means of the Trauma and Distress Scale (TADS), and ACEs in both parents were measured with a specific questionnaire. A linear regression model was used to examine the association between parents' ACEs and the children's emotional neglect scores.

RESULTS

The children's mean emotional neglect score was 8.11 on a scale from 5 to 25. There was no significant difference between males (mean 8.01) and females (mean 8.19). Only father's ACEs were associated with child's emotional neglect score. In the linear regression model, the children's emotional neglect scores increased by 0.3 points for father's ACE.

CONCLUSIONS

Our findings suggest that father's ACEs may increase the child's risk of experiencing emotional neglect. It seems that childhood adversities are transferred from parents to children, but larger samples would be needed to confirm these findings.

Differential Pathways from Child Maltreatment Types to Insecure Adult Attachment Styles via Psychological and Social Resources: A Bayesian Network Analysis

Child maltreatment has been linked to insecure adult attachment. However, it is not yet clear how different child maltreatment types are associated with attachment-related anxiety and avoidance in adulthood; and whether resilience against these insecure attachment styles is dependent on risk-specific resources. Therefore, this study explored differential pathways from child maltreatment types to attachment-related anxiety and avoidance in adulthood and examined whether psychological resources (self-esteem) and social resources (perceived social support) show risk-specific effects. An online survey retrospectively assessed experiences of child maltreatment, the level of attachment-related anxiety and avoidance in adulthood, self-esteem, and perceived social support in N = 604 former members of fundamentalist Christian faith communities (mean age = 41.27 years, SD = 12.50; 65.90% female). Cross-sectional data was analyzed using Bayesian network analysis. Only emotional child maltreatment showed direct relationships to insecure adult attachment. Specifically, emotional abuse and emotional neglect were associated with anxious and avoidant adult attachment, respectively. The effects of other child abuse types on adult attachment were mediated through emotional abuse, which indicated patterns of complex traumatization. Self-esteem mediated the effect of emotional abuse on anxious attachment, while perceived social support mediated the effect of emotional neglect on avoidant attachment. Social support was also linked to self-esteem and was therefore also important for individuals with experiences of emotional abuse. This study showed that child maltreatment types and their interactions are meaningfully linked to attachment-related anxiety and avoidance in adulthood. Interventions for survivors of child maltreatment should focus on risk-specific resources to support their resilience.

Current issues and challenges in the definition and operationalization of child maltreatment: A scoping review

BACKGROUND

Studies show considerable variability in the definitions and operationalization of child maltreatment (CM), which limits research, policy formation, surveillance, and cross-country and cross-sector comparisons.

OBJECTIVE

To review the recent literature (2011-2021) to understand current issues and challenges in defining CM, to assist in the planning, testing and implementing of CM conceptualizations.

METHODS

We searched eight international databases. Articles were included if the substantive content was related to issues, challenges, and debates in defining CM, and the article was an original study, review, commentary, report, or guideline. The review followed methodological guidance for the conduct of scoping reviews and was reported in accordance with the PRISMA-ScR checklist. Four experts in CM conducted a thematic analysis to summarize findings. Methodological rigor of the included studies was not formally assessed.

RESULTS

We identified 7372 potentially relevant articles; 55 full-text studies were assessed for eligibility, 25 satisfied the inclusion criteria. We identified three themes: 1) strategies to define CM, including the integration of child and victim perspectives; 2) difficulties in defining specific CM types; and 3) real-world implications for research, prevention and policy.

CONCLUSIONS

Despite longstanding concerns, challenges regarding the definitions of CM persist. A small minority of studies have tested and implemented CM definitions and operationalizations in practice. The findings will inform international multi-sectoral processes to develop uniform definitions of CM, for example by highlighting the need to acknowledge challenges in defining some CM types and emphasizing the importance of considering the perspectives of children and CM survivors.

Psychometric properties of the Adverse Childhood Experiences Questionnaire 10 item version (ACE-10) among Hungarian adolescents

Introduction

Although a number of studies have been conducted since the 1995 initiation of the ACE study to map the effects of adverse childhood experiences, few studies have examined the psychometric properties of the individual versions of the ACE questionnaire.

Aims

The Adverse Childhood Experiences Questionnaire 10 item version (ACE-10) has only been tested in a single study in an adult population, while its applicability in a particularly vulnerable population, the adolescents, has not been investigated yet. Our present study aims to address this gap in an adolescent sample of 792 subjects from a non-representative general population.

Methods

Besides demographic data, the Adverse Childhood Experiences Questionnaire 10 item version (ACE-10), the Strengths and Difficulties Questionnaire (SDQ), and the HBSC Symptom Checklist (HBSC-SCL) were employed.

Results

Our results showed acceptable internal consistency (ɵ = 0.86, α = 0.64) and adequate internal validity (r = 0.28-0.70, p < 0.001). In addition, proper concurrent criterion validity of the questionnaire was found when tested along the SDQ and HBSC-SCL items.

Conclusion

Our results demonstrate that the ACE-10 is suitable for assessing intrafamilial adverse childhood experiences in adolescents.

Adaptation and validation of the Juvenile Victimization Questionnaire-R2 for a national study of child maltreatment in Australia

BACKGROUND

To establish national prevalence of child maltreatment, reliable, valid and contextually appropriate measurement is needed. This paper outlines the refinement, adaptation and testing of child maltreatment sections of the Juvenile Victimization Questionnaire (JVQ)-R2 for use in the Australian context.

METHODS

Three phases were undertaken: 1) Conceptual analysis of the five forms of child maltreatment (physical abuse, sexual abuse, emotional or psychological abuse, neglect, and experience of domestic violence), item mapping and review, item development, and independent expert review; 2) Cognitive testing with members of the general population, and individuals who have experienced maltreatment; and 3) Pilot testing and quantitative psychometric assessment with a random sample of Australians aged 16-65+ years.

RESULTS

The final measure included a total of 17 child maltreatment screener items, assessing Physical Abuse (2 items), Sexual abuse (5 items (including 2 non-contact items and 3 contact items), Emotional Abuse (3 items), Neglect (3 items), and Experience of Domestic Violence (4 items). Screener items were also included on corporal punishment (1 item), and internet sexual victimization (2 items). The final 17-item revised JVQ had high face and conceptual validity and good internal reliability (α = 0.86 and Ω = 0.87). Test re-test reliability was moderate to high for individual screeners ranging from k = 0.45 to 0.89.

CONCLUSIONS

Results indicate the Juvenile Victimization Questionnaire-R2: Adapted Version (Australian Child Maltreatment Study) is a suitable instrument for assessing population-wide prevalence of maltreatment. It is congruent with conceptual models of maltreatment and shows good reliability and validity in this Australian sample.

Examining the Role of Interpersonal Violence in Racial Disparities in Breastfeeding in North Dakota (ND PRAMS 2017-2019)

BACKGROUND

The 2019 overall breastfeeding initiation rate in the US was 84.1%, yet only 76.6% of American Indian (AI) women initiated breastfeeding. In North Dakota (ND), AI women have greater exposure to interpersonal violence than other racial/ethnic groups. Stress associated with interpersonal violence may interfere with processes important to breastfeeding. We explored whether interpersonal violence partially explains racial/ethnic disparities in breastfeeding in ND.

METHODS

Data for 2161 women were drawn from the 2017-2019 ND Pregnancy Risk Assessment Monitoring System. Breastfeeding questions in PRAMS have been tested among diverse populations. Breastfeeding initiation was self-report to "Did you ever breastfeed or pump breast milk to feed your new baby, even for a short period?" (yes/no). Breastfeeding duration (2 months; 6 months) was self-reported how many weeks or months of breastmilk feeding. Interpersonal violence for both 12 months before and during pregnancy based on self-report (yes/no) of violence from a husband/partner, family member, someone else, or ex-husband/partner. An "Any violence" variable was created if participants reported "yes" to any violence. Logistic regression models estimated crude and adjusted odds ratios (OR) and 95% confidence intervals (95% CI) for breastfeeding outcomes among AI and Other Race women compared to White women. Sequential models were adjusted for interpersonal violence (husband/partner, family member, someone else, ex-husband/partner, or any).

RESULTS

AI women had 45% reduced odds of initiating breastfeeding (OR: 0.55, 95% CI: 0.36, 0.82) compared to white women. Including interpersonal violence during pregnancy did not change results. Similar patterns were observed for all breastfeeding outcomes and all interpersonal violence exposures.

DISCUSSION

Interpersonal violence does not explain the disparity in breastfeeding in ND. Considering cultural ties to the tradition of breastfeeding and the role of colonization may provide a better understanding of breastfeeding among AI populations.

The prevalence of child maltreatment in Australia: findings from a national survey

OBJECTIVES

To estimate the prevalence in Australia of each type of child maltreatment; to identify gender- and age group-related differences in prevalence.

DESIGN, SETTING

Cross-sectional national survey; mobile telephone interviews using random digit dialling (computer-generated), Australia, 9 April - 11 October 2021. Retrospective self-report data using validated questionnaire (Juvenile Victimisation Questionnaire-R2 Adapted Version (Australian Child Maltreatment Study).

PARTICIPANTS

People aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16-24 years and 1000 respondents each from five further age groups (25-34, 35-44, 45-54, 55-64, 65 years or more).

MAIN OUTCOME MEASURES

Proportions of respondents reporting physical abuse, sexual abuse, emotional abuse, neglect, and exposure to domestic violence to age 18 years, assessed with the Juvenile Victimization Questionnaire-R2 Adapted Version (Australian Child Maltreatment Study), overall and by gender and age group, and weighted to reflect characteristics of the Australian population aged 16 years or more in 2016.

RESULTS

Complete survey data were available for 8503 eligible participants (14% response rate). Physical abuse was reported by 32.0% of respondents (95% confidence interval [CI], 30.7-33.3%), sexual abuse by 28.5% (95% CI, 27.3-29.8%), emotional abuse by 30.9% (95% CI, 29.7-32.2%), neglect by 8.9% (95% CI, 8.1-9.7%), and exposure to domestic violence by 39.6% (95% CI, 38.3-40.9%). The proportions of respondents who reported sexual abuse, emotional abuse, or neglect were each statistically significantly larger for women than men. The reported prevalence of physical abuse by respondents aged 16-24 years was lower than for those aged 25-34 years, and that of sexual abuse was lower than for those aged 35-44 years, suggesting recent declines in the prevalence of these maltreatment types.

CONCLUSIONS

Child maltreatment is common in Australia, and larger proportions of women than men report having experienced sexual abuse, emotional abuse, and neglect during childhood. As physical and sexual abuse may have declined recently, public health policy and practice may have positive effects, justifying continued monitoring and prevention activities.

The association between child maltreatment and mental disorders in the Australian Child Maltreatment Study

OBJECTIVES

To examine the associations between experiences of child maltreatment and mental disorders in the Australian population.

DESIGN

Population-representative survey conducted by computer-assisted telephone interviewing.

SETTING, PARTICIPANTS

Australian residents aged 16 years and older.

MAIN OUTCOME MEASURES

Mental disorder diagnoses of lifetime major depressive disorder, current alcohol use disorder (mild, moderate and severe), current generalised anxiety disorder and current post-traumatic stress disorder.

RESULTS

More than one in three Australians (3606/8503 surveyed participants; 38.0%; 95% CI, 36.7-39.3%) met the diagnostic criteria for a mental disorder. The prevalence of mental disorders in non-maltreated participants was 21.6% (95% CI, 19.9-23.3%; n = 851). This increased to 36.2% (95% CI, 33.5-38.9%; n = 764) for those who experienced a single type of maltreatment and 54.8% (95% CI, 52.6-56.9%; n = 1991) for participants who experienced multi-type maltreatment. Compared with non-maltreated Australians, maltreated participants had about three times the odds of any mental disorder (odds ratio [OR], 2.82; 95% CI, 2.47-3.22), generalised anxiety disorder (OR, 3.14; 95% CI, 2.48-3.97), major depressive disorder (OR, 3.19; 95% CI, 2.68-3.80) and severe alcohol use disorder (OR, 2.62; 95% CI, 1.83-3.76), and almost five times the odds of post-traumatic stress disorder (OR, 4.60; 95% CI, 3.00-7.07). Associations between experiences of child maltreatment and mental disorders were strongest for sexual abuse, emotional abuse and multi-type maltreatment. The strength of the associations did not differ by gender. Adjustment for childhood and current financial hardship and for current socio-economic status did not significantly attenuate the associations.

CONCLUSIONS

Mental disorders are significantly more likely to occur in individuals who experience child maltreatment, particularly multi-type maltreatment. Prevention of child maltreatment provides an opportunity to substantially reduce the prevalence of mental illness and improve the health of the Australian population.

The Australian Child Maltreatment Study (ACMS), a national survey of the prevalence of child maltreatment and its correlates: methodology

OBJECTIVES

To describe the aims, design, methodology, and respondent sample representativeness of the Australian Child Maltreatment Study (ACMS).

DESIGN, SETTING

Cross-sectional, retrospective survey; computer-assisted mobile telephone interviewing using random digit dialling (computer-generated), Australia, 9 April - 11 October 2021.

PARTICIPANTS

People aged 16 years or more. The target sample size was 8500 respondents: 3500 people aged 16-24 years and 1000 respondents each from five further age groups (25-34, 35-44, 45-54, 55-64, 65 years or more).

MAIN OUTCOME MEASURES

Primary outcomes: Emotional abuse, neglect, physical abuse, sexual abuse, exposure to domestic violence during childhood, assessed with the Juvenile Victimization Questionnaire-R2 Adapted Version (Australian Child Maltreatment Study).

SECONDARY OUTCOMES

selected mental disorder diagnoses (Mini International Neuropsychiatric Interview, MINI), selected physical health conditions, health risk behaviours, health service use.

RESULTS

The demographic characteristics of the ACMS sample were similar to those of the Australian population in 2016 with respect to gender, Indigenous status, region and remoteness category of residence, and marital status, but larger proportions of participants were born in Australia, lived in areas of higher socio-economic status, had tertiary qualifications, and had income greater than $1250 per week. Population weights were derived to adjust for these differences. Associations between the number of calls required to recruit participants and maltreatment rates and health outcomes were not statistically significant.

CONCLUSIONS

The ACMS provides the first reliable estimates of the prevalence of each type of child maltreatment in Australia. These estimates, and those of associated mental health and health risk behaviours reported in this supplement can inform policy and practice initiatives for reducing the prevalence of child maltreatment and its consequences. Our benchmark study also provides baseline data for repeated waves of the ACMS that will assess the effectiveness of these initiatives.

Childhood maltreatment and DNA methylation: A systematic review

Child maltreatment (CM) encompasses sexual abuse, physical abuse, emotional abuse, neglect, and exposure to domestic and family violence. Epigenetic research investigating CM has focused on differential DNA methylation (DNAm) in genes associated with the stress response, but there has been limited evaluation of the specific effects of subtypes of CM. This systematic review of literature investigating DNAm associated with CM in non-clinical populations aimed to summarise the approaches currently used in research, how the type of maltreatment and age of exposure were encoded via methylation, and which genes have consistently been associated with CM. A total of fifty-four papers were eligible for review, including forty-one candidate gene studies, eight epigenome-wide association studies, and five studies with a mixed design. The ways in which the various forms of CM were conceptualised and measured varied between papers. Future studies would benefit from assessments that employ conceptually robust definitions of CM, and that capture important contextual information such as age of exposure and subtype of CM.

Population-Based Estimates of Associations Between Child Maltreatment Types: A Meta-Analysis

Although it is accepted that experiences of child maltreatment are multidimensional and often include several correlated but distinct experiences, many clinical and research decisions regarding exposure and treatment do not consider their potential overlap or potential independence. The purpose of this meta-analysis-using a single retrospective self-report measure, the Childhood Trauma Questionnaire (CTQ), in population-representative samples-was to investigate the magnitude and specificity of associations between forms of child maltreatment. A systematic review of studies available on PubMed, PsycINFO, and Google Scholar was conducted, resulting in the inclusion of nine journal articles, 11 independent samples, and 25,415 participants. Data were converted from Pearson correlations to Z statistics and pooled using a random effects model. All maltreatment types were positively and significantly associated. Effect sizes varied from medium to large, with (1) physical abuse and emotional abuse (Z = 0.72, 95% CI [.48, .96]), (2) physical neglect and emotional neglect (Z = 0.62, 95% CI [.43, .81]), and (3) emotional abuse and emotional neglect (Z = 0.54, 95% CI [.35, .72]) demonstrating the strongest associations. These analyses provide evidence of the associations between types of child maltreatment, indicate the likelihood of shared risk, and point to characteristics that may link different types of maltreatment. These findings have important clinical implications as they may help guide comprehensive screening for associated maltreatment types as well as intervention and prevention efforts. Limitations include the relatively few studies included and those associated with the CTQ-a retrospective, self-report measure that does not account for the concurrence of experiences.

School- and community-level protective factors for resilience among chronically maltreated children in Japan

PURPOSE

Few studies have investigated how school- and community-level modifiable factors might enhance resilience, defined as an ability to recover from and cope with adversity, among chronically maltreated pre-adolescent children. This study aims to investigate school and community factors that can increase children's resilience following maltreatment.

METHODS

We used data from the Adachi child health impact of living difficulty (A-CHILD) Study, a population-based prospective longitudinal study starting with first-grade children in all public elementary schools in Adachi City, Tokyo, Japan in 2015. Children who experienced chronic maltreatment while in 1st and 4th grades and whose resilience scores were available at those grades were included in the analysis (N = 789). Crude and multiple regressions were used to examine associations of child-reported school factors (i.e., school social capital, number of friends to consult with) and community factors (i.e., having a non-parental role model and supportive adult, having a third place, which is defined as a place other than home to spend time after school) with parent-reported resilience at 4th grade. These regressions were also performed stratified by sex.

RESULTS

School social capital and having a non-parental role model at 4th grade were positively associated with resilience after adjusting covariates, including resilience at 1st grade [coefficient = 3.63, 95% confidence intervals (CI) 2.26-4.99; coefficient = 2.52, 95% CI 0.57-4.38, respectively]. Analysis by sex revealed that having a supportive adult, but not a role model, was associated with resilience among girls (coefficient = 5.50, 95% CI 0.20-10.8).

CONCLUSIONS

The findings suggest that school and community factors can promote resilience following child maltreatment, and these factors are different between boys and girls.

The association between abused adults and substance abuse in Taiwan, 2000-2015

OBJECTIVE

To investigate whether adults suffering from violence were at risk of substance abuse and provides insight into the relationship between male and female abusers and substance abuse from 2000 to 2015 in Taiwan.

METHODS

This study used data on outpatient, emergency, and inpatient visits for 2 million people enrolled in universal health insurance from 2000 to 2015. ICD-9 diagnosis codes 995.8 (abused adult) and E960-E969 (homicide and injury purposely inflicted by other persons) were defined in this case study, analyzing first-time violence in adults aged 18-64 (study group). Non-abused patients (control group) were matched in a 1:4 ratio, and the paired variables were gender, age (± 1 year), pre-exposure Charlson Comorbidity Index, and year of medical treatment. SAS 9.4 and Cox regression were used for data analysis.

RESULTS

A total of 8,726 people suffered violence (control group: 34,904 people) over 15 years. The prevalence of substance abuse among victims of violence was 78.3/10⁴, 61.9/10⁴, and 51.5/10⁴ for tobacco use disorder, alcoholism, and alcohol abuse, respectively. The risk (adults, overall) of drug abuse, drug dependence, and alcoholism after exposure to violence (average 9 years) was 7.47, 7.15, and 6.86 times (p < 0.01), respectively, compared with those without violence. The risk (adults, males) of drug abuse, drug dependence, and alcohol abuse after exposure to violence (average 9 years) was 6.85, 6.27, and 6.07 times, respectively, higher than those without violence (p < 0.01). Risks of drug dependence, alcohol abuse and alcoholism (adults, females) after exposure to violence (average 9 years) were 14.92, 12.26, and 11.55 times, respectively, higher than non-abused ones (p < 0.01).

CONCLUSION

The risks of substance abuse, after adult violence, are higher than in those who have not suffered violent injuries.

Child Maltreatment and Long-Term Physical and Mental Health Outcomes: An Exploration of Biopsychosocial Determinants and Implications for Prevention

Child maltreatment rates remain unacceptably high and rates are likely to escalate as COVID-related economic problems continue. A comprehensive and evidence-building approach is needed to prevent, detect and intervene where child maltreatment occurs. This review identifies key challenges in definitions, overviews the latest data on prevalence rates, reviews risk and protective factors, and examines common long-term mental health outcomes for children who experience maltreatment. The review takes a systems approach to child maltreatment outcomes through its focus on the overall burden of disease, gene-environment interactions, neurobiological mechanisms and social ecologies linking maltreatment to mental ill-health. Five recommendations relating to the accurate measurement of trends, research on brain structures and processes, improving the reach and impact of teleservices for detecting, preventing and treating child maladjustment, community-based approaches, and building population-focused multidisciplinary alliances and think tanks are presented.

Childhood Prevalence of Involvement with the Child Protection System in Quebec: A Longitudinal Study

The goal of this study, the first of its kind in Canada, was to estimate the child lifetime prevalence of child protection involvement in Quebec. Using administrative and population data spanning 17 years, we performed a survival analysis of initial incidents of child protection reports, confirmed reports, confirmation of a child's security or development being compromised, and placement outside the home for one day or more. We found that before reaching the age of 18 years, over 18% of children were reported to child protection at least once, one in every ten children (10.1%) in the province had a report that led to the finding of their security or development being compromised, and over 5% were placed outside the home. We found that neglect was a primary concern in close to half (47.6%) of cases. By using a full population dataset, we obtained a more accurate prevalence estimate than studies using synthetic cohort life tables. These findings only captured initial incidents of involvement with child protection, meaning this study does not show the extent of recurrent involvement for some children. The findings reflect prior results showing that neglect is common in initial child protection involvement but less pervasive than has been shown in incidence studies, suggesting that recurrent child protection involvement is more driven by neglect than initial incidents are.

Child Maltreatment Reporting Practices by a Person Most Knowledgeable for Children and Youth: A Rapid Scoping Review

Child maltreatment is a global public health and child rights crisis made worse by the ongoing COVID-19 pandemic. While understanding the breadth of the child maltreatment crisis is foundational to informing prevention and response efforts, determining accurate estimates of child maltreatment remains challenging. Alternative informants (parents, caregivers, a Person Most Knowledgeable-PMK) are often tasked with reporting on children's maltreatment experiences in surveys to mitigate concerns associated with reporting child maltreatment. The overall purpose of this study was to examine child maltreatment reporting practices in surveys by PMKs for children and youth. The research question is: "What is the nature of the evidence of child maltreatment reporting practices in general population surveys by PMKs for children and youth?" A rapid scoping review was conducted to achieve the study's purpose. A search strategy was conducted in nine databases (e.g., MEDLINE, EBSCO, Scopus, Global Health, ProQuest). The findings from this review indicate that most studies involved PMK informants (i.e., maternal caregivers), included representative samples from primarily Western contexts, and utilized validated measures to assess child maltreatment. Half of the studies assessed involved multi-informant reports, including the PMKs and child/youth. Overall, the congruence between PMK-reported and child/youth-reported child maltreatment experiences was low-to-fair/moderate, and children/youth reported more maltreatment than the PMKs.

Adult abuse and poor prognosis in Taiwan, 2000-2015: a cohort study

BACKGROUND

To investigate the risk of poor prognosis regarding schizophrenic disorders, psychotic disorders, suicide, self-inflicted injury, and mortality after adult violence from 2000 to 2015 in Taiwan.

METHODS

This study used data from National Health Insurance Research Database (NHIRD) on outpatient, emergency, and inpatient visits for two million people enrolled in the National Health Insurance (NHI) from 2000 to 2015. The case study defined ICD-9 diagnosis code N code 995.8 (abused adult) or E code E960-E969 (homicide and intentional injury of another). It analyzed first-time violence in adults aged 18-64 years (study group). 1:4 ratio was matched with injury and non-violent patients (control group). The paired variables were sex, age (± 1 year), pre-exposure to the Charlson comorbidity index, and year of medical treatment. Statistical analysis was conducted using SAS 9.4 and Cox regression for data analysis.

RESULTS

In total, 8,726 individuals experienced violence (case group) while34,904 did not experienced violence (control group) over 15 years. The prevalence of poor prognosis among victims of violence was 25.4/10⁴, 31.3/10⁴, 10.5/10,⁴ and 104.6/10⁴ for schizophrenic disorders, psychotic disorders, suicide or self-inflicted injury and mortality, respectively. Among adults, the risks of suicide or self-inflicted injury, schizophrenic disorders, psychotic disorders, and mortality after exposure to violence (average 9 years) were 6.87-, 5.63-, 4.10-, and 2.50-times (p < 0.01), respectively, compared with those without violence. Among males, the risks were 5.66-, 3.85-, 3.59- and 2.51-times higher, respectively, than those without violence (p < 0.01), and they were 21.93-, 5.57-, 4.60- and 2.46-times higher than those without violence (p < 0.01) among females.

CONCLUSION

The risk of poor prognosis regarding schizophrenic disorders, psychotic disorders, suicide, or self-inflicted injury and mortality after adult violence was higher than in those who have not experienced a violent injury. Adults at the highest risk for violent suicide or self-inflicted injuries due to exposure to violent injuries -males were at risk for schizophrenia and females were at risk for suicide or self-inflicted injuries. Therefore, it is necessary for social workers and medical personnel to pay attention to the psychological status of victims of violence.

"What does that mean?": The content validity of the ISPCAN Child Abuse Screening Tool - Child version (ICAST-C) in Romania, South Africa, and the Philippines

BACKGROUND

The International Society for Prevention of Child Abuse and Neglect (ISPCAN) Child Abuse Screening Tool (Children's Version), known as the ICAST-C Version 3, is used widely to assess violence against children, but there is limited psychometric evidence, especially on content validity.

OBJECTIVE

This study aimed to assess the content validity of the ICAST-C with adolescents in Romania, South Africa, and the Philippines.

METHODS

A purposive sample of adolescents (N = 53, 51 % female) were recruited from urban areas in Romania, the Eastern Cape Province of South Africa, and Metro Manila, Philippines. Semi-structured one-on-one in-depth cognitive interviews sought adolescent perspectives on the relevance, comprehensibility, and comprehensiveness of the ICAST-C. Data were analysed using template analysis.

RESULTS

The ICAST-C was broadly perceived to be relevant and comprehensive in measuring violence against children in all study locations. However, there were issues with the comprehensibility of the measure, described at three levels: interpreting items, undertaking coherent elaborations of relevant behaviors and places, and generating a coherent response to the questions.

CONCLUSIONS

Suggestions to revise the ICAST-C include, among others, adding a practice or how-to section on answering the survey, clarifying the intent of questions, especially on neglect and sexual abuse, emphasizing that questions cover all locations, and asking more positive questions. Pilot studies testing the content validity and cultural appropriateness are needed as a matter of practice in large self-report surveys.

Asking youth and adults about child maltreatment: a review of government surveys

OBJECTIVES

In this review we: (1) identify and describe nationally representative surveys with child maltreatment (CM) questions conducted by governments in low-income, middle-income and high-income countries and (2) describe procedures implemented to address respondents' safety and minimise potential distress.

DESIGN

We conducted a systematic search across eight databases from 1 January 2000 to 5 July 2021 to identify original studies with information about relevant surveys. Additional information about surveys was obtained through survey methods studies, survey reports, survey websites or by identifying full questionnaires (when available).

RESULTS

Forty-six studies representing 139 surveys (98 youth and 41 adult) conducted by governments from 105 countries were identified. Surveys implemented a variety of procedures to maximise the safety and/or reduce distress for respondents including providing the option to withdraw from the survey and/or securing confidentiality and privacy for the respondent. In many surveys, further steps were taken such as providing information for support services, providing sensitivity training to survey administrators when interviews were conducted, among others. A minority of surveys took additional steps to empirically assess potential distress experienced by respondents.

CONCLUSIONS

Assessing risk and protective factors and developing effective interventions and policies are essential to reduce the burden of violence against children. While asking about experiences of CM requires careful consideration, procedures to maximise the safety and minimise potential distress to respondents have been successfully implemented globally, although practices differ across surveys. Further analysis is required to assist governments to implement the best possible safety protocols to protect respondents in future surveys.

COVID-19 and family violence: A rapid review of literature published up to 1 year after the pandemic declaration

Background

After the World Health Organization declared COVID-19 a pandemic on March 11, 2020, public health restrictions were introduced to slow COVID-19 transmission and prevent health systems overload globally. Work-from-home requirements, online schooling, and social isolation measures required adaptations that may have exposed parents and children to family violence, including intimate partner violence and child abuse and neglect, especially in the early days of the pandemic. Thus, we sought to: (1) examine the occurrence of family violence; (2) identify factors associated with family violence; and (3) identify relevant recommendations, from COVID-19 literature published up to 1 year after the pandemic declaration.

Methods

This review was registered on PROSPERO (CRD42021241622), employed rapid review methods, and extracted data from eligible papers in medical and health databases published between December 1, 2019 and March 11, 2021 in MEDLINE, PsycINFO, CINAHL, and Embase.

Findings

28 articles including 29 studies were included in the rapid review. While many studies of families/households revealed rises in family violence incidence, official justice, police, and emergency department records noted declines during the pandemic. Parental stress, burnout, mental distress (i.e. depression), difficulty managing COVID-19 measures, social isolation, and financial and occupational losses were related to increases in family violence. Health services should adopt approaches to prevent family violence, treat victims in the context of public health restrictions, and increase training for digital service usage by health and educational professionals.

Interpretation

Globally, restrictions aimed to limit the spread of COVID-19 may have increased the risk factors and incidence of family violence in communities. Official records of family violence may be biased toward under-reporting in the context of pandemics and should be interpreted with caution.

Estimating the changing burden of disease attributable to interpersonal violence in South Africa for 2000, 2006 and 2012

Background. South Africa (SA)’s high rate of interpersonal violence persists as a leading public health problem for the country. The first South African Comparative Risk Assessment Study (SACRA1) in 2000 quantified the long-term mental and physical health burden attributable to interpersonal violence by supplementing the direct injury burden of disease attributable to interpersonal violence injuries with the substantial contribution of mental health, behavioural and reproductive health consequences accruing from exposure to intimate partner violence (IPV) and child sexual abuse. Objectives. To revise and improve these estimates by including the additional burden from other forms of child maltreatment, community violence, sexual violence by non-partners, and bullying victimisation in SA for 2000, 2006 and 2012, and trends over time. Methods. We used comparative risk assessment methods to calculate population attributable fractions (PAFs) for interpersonal violence. This method requires inputs on the prevalence of exposure to the interpersonal violence risk factor subtypes, namely child maltreatment, bullying, IPV, sexual violence by non-partners and other community violence; the burden of related health outcomes (mortality and morbidity); and relative risks of health outcomes in individuals exposed to the risk factor v. those unexposed. We estimated the PAF for the combinations of all interpersonal violence subtypes together to estimate the burden attributable to interpersonal violence overall for 2000, 2006 and 2012. Results. Between 2000 and 2012, there was a decrease in interpersonal violence age-standardised attributable death rates from 100 to 71 per 100 000. In the second South African Comparative Risk Assessment Study (SACRA2), estimates of the attributable disability-adjusted life years (DALYs) for interpersonal violence for the year 2000 were revised, from 1.7 million to 2 million DALYs, taking into account attributable mortality and disability from additional forms of violence. There was a decrease in DALYs attributable to interpersonal violence from 2 million in 2000 to 1.75 million in 2012, accounting for 8.5% of the total burden for SA, ranking second highest, after unsafe sex, among 18 risk factors evaluated in 2012. Conclusion. Overall, interpersonal violence-attributable DALYs decreased substantially but remain high. The reduction in age-standardised attributable death rates indicates that some policy and social intervention aspects are effective. Further strengthening of existing laws pertaining to interpersonal violence, and other prevention measures, are needed to intensify the prevention of violence, particularly gender-based violence. Additional forms of violence included in this analysis have improved our understanding of the interpersonal violence burden, but the attributable burden in males, although exceedingly high, remains an underestimate. There is a need to improve the epidemiological data on prevalence and risks for the different types of interpersonal violence, particularly for males.

Childhood adversities and suicidal thoughts and behaviors among first-year college students: results from the WMH-ICS initiative

PURPOSE

To investigate the associations of childhood adversities (CAs) with lifetime onset and transitions across suicidal thoughts and behaviors (STB) among incoming college students.

METHODS

Web-based self-report surveys administered to 20,842 incoming college students from nine countries (response rate 45.6%) assessed lifetime suicidal ideation, plans and attempts along with seven CAs: parental psychopathology, three types of abuse (emotional, physical, sexual), neglect, bully victimization, and dating violence. Logistic regression estimated individual- and population-level associations using CA operationalizations for type, number, severity, and frequency.

RESULTS

Associations of CAs with lifetime ideation and the transition from ideation to plan were best explained by the exact number of CA types (OR range 1.32-52.30 for exactly two to seven CAs). Associations of CAs with a transition to attempts were best explained by the frequency of specific CA types (scaled 0-4). Attempts among ideators with a plan were significantly associated with all seven CAs (OR range 1.16-1.59) and associations remained significant in adjusted analyses with the frequency of sexual abuse (OR = 1.42), dating violence (OR = 1.29), physical abuse (OR = 1.17) and bully victimization (OR = 1.17). Attempts among ideators without plan were significantly associated with frequency of emotional abuse (OR = 1.29) and bully victimization (OR = 1.36), in both unadjusted and adjusted analyses. Population attributable risk simulations found 63% of ideation and 30-47% of STB transitions associated with CAs.

CONCLUSION

Early-life adversities represent a potentially important driver in explaining lifetime STB among incoming college students. Comprehensive intervention strategies that prevent or reduce the negative effects of CAs may reduce subsequent onset of STB.

Childhood maltreatment and decision-making autonomy in adulthood: The mediating roles of self-esteem and social support

BACKGROUND

Childhood maltreatment (CM) is connected with a large number of maladaptive long-term outcomes. Effective prevention and intervention hinges partly on our understanding of the key mediating mechanisms that help account for the relationship between child maltreatment and its long-term consequences. We know the consequences of CM can extend into adulthood, including the intergenerational transmission of violence, re-victimization, high-risk behavior, and persisting mental health problems. We argue that CM also likely affects decision-making autonomy in adulthood, limiting their independence and exaggerating their risk for other poor outcomes. We suggest that the effects of CM on self-esteem and access to social support mediate this relationship, helping to explain how and why CM impacts autonomy in the long term.

OBJECTIVE

This study aimed to examine these relationships using a cross-sectional sample of currently married women of Bangladesh aged 15-49 years (N = 426).

METHOD

A multi-stage random sampling technique was employed for data collection and a multivariate logistic regression technique was applied for data analysis.

RESULTS

Results from the multivariate logistic regression model revealed a direct effect of a history of CM on limited decision-making autonomy in adulthood and a full mediating effect of self-esteem and social support on the associations between CM and decision-making autonomy in women, even after adjusting for theoretically and empirically relevant covariates.

CONCLUSIONS

The study findings provide insight into the mechanisms by which early childhood experiences impact autonomous decision-making. However, causality cannot be determined because of the cross-sectional design. Finally, our findings suggest that the influence of CM on autonomy could be augmented by self-esteem recovery through social support from family, friends, and peers.

Reporting suspicion of child maltreatment - a 5 yr follow-up of public dental health care workers in Norway

OBJECTIVE

This study examined stability and change of Norwegian dental health care workers' mandated reporting of suspected child maltreatment from 2014 to 2019 as well as the influence on reporting practices from regional, sociodemographic- and attitudinal factors. It was hypothesised that those factors associate independently with reporting practices across the survey period.

METHODS

In 2014 a census of 1542 dental health care workers employed in the public dental health care service (PDHS) were invited to participate in an electronic survey and 1200 (response 77.8%) consented to participation. Corresponding figures in 2019 were 1791 and 1270 (response 70.9%). Of the 1200 participants in 2014, 591 participated in 2019 (follow up 49.3%).

RESULTS

A total of 58% and 25.7% of the dental health care workers confirmed ever reporting and avoidance of reporting in both survey years whereas 24.6% and 17.2% changed the status of ever- and avoiding reporting across time. The likelihood of being a stable reporter was greatest in experienced participants, those living in eastern parts of Norway and confirming professional obligations to report. At the population level, 59.6% and 79.5% confirmed ever reporting of suspected maltreatment in 2014 and 2019. Corresponding figures for confirmed avoidance of reporting were 33.9% and 37.9%.

CONCLUSION

Reporting of suspected child maltreatment is maintained at a relatively high level and varies by socio-demographic and attitudinal concerns.

Associations of anxiety and depression with suicide experiences in individuals with and without childhood trauma: The role of social support

No studies have examined the differences and similarities between individuals with and without experiences of childhood sexual and/or physical abuse in relation to anxiety and depression severity, perceived social support, and suicide experiences. Furthermore, whether the strength of these associations differs between these two groups, and whether the buffering role of perceived social support is equally effective, remain unknown. This study, which was based on 842 British participants, aimed to address these gaps. There were three key findings: i) abused individuals reported significantly more severe depression, anxiety, and suicide experiences, and lower social support, ii) the associations between depression, anxiety, and suicide experiences did not differ between these groups, whereas the association between social support and suicide experiences was more pronounced in abused individuals, and iii) perceived social support acted as a moderator of the association between depression and suicide experiences in both groups. These findings are important because they suggest that for the individuals with childhood trauma perceptions of being less supported by their significant others may lead to suicide acts. Furthermore, perceptions of being socially supported appeared to weaken the association between depression and suicide experiences equally in individuals with and without childhood trauma.

Sexual orientation differences in childhood sexual abuse, suicide attempts, and DSM-5 alcohol, tobacco, other drug use, and mental health disorders in the US

BACKGROUND

Childhood sexual abuse (CSA) contributes to increased risk of substance use and mental health disorders in the general population.

OBJECTIVE

To assess the prevalence and associations of CSA and suicide attempts, substance use, and mental health disorders as a function of sex (female, male) and sexual orientation (lesbian, gay, bisexual, heterosexual-identified with same-sex attraction and/or behavior, heterosexual-identified without same-sex attraction and/or behavior, and unsure).

PARTICIPANTS AND SETTING

Data were collected using structured diagnostic face-to-face interviews in a nationally representative sample of 36,309 US adults.

METHODS

We used descriptive statistics and logistic regression modeling to analyze data from the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC-III).

RESULTS

Childhood sexual abuse was most prevalent among sexual minorities, especially bisexual females. Nearly one-third of bisexual females (30.6%) reported experiencing two or more types of CSA, p < .001. Among all participants, exposure to one or more types of CSA was associated with greater odds of lifetime suicide attempts, Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) alcohol, tobacco or other drug use disorder, and mental health disorders, after adjusting for other childhood adversity/maltreatment and general life stressors.

CONCLUSIONS

Sexual minority females and males in the US are more likely than their heterosexual counterparts to report CSA. Higher risk of suicide attempts and DSM-5 alcohol, tobacco, other drug use, and mental health disorders in adulthood was directly associated with CSA, particularly among bisexual females. Health professionals working with individuals who have experienced CSA should assess these risks and intervene as needed.
