A Multisource Approach to Assessing Child Maltreatment From Records, Caregivers, and Children

Measurement Models of Child Maltreatment and Associations With Suicidal Ideation Endorsement by Youth in Foster Care: A Multiverse Analytic Approach

Youth suicidal ideation is a prevalent experience, particularly among youth exposed to maltreatment, with a variety of indicators such as youth statements of ideation. To better understand suicidal ideation, and the associations with youth mental health outcomes, a fruitful path may be through the study of the dimensions (e.g., severity, frequency) of maltreatment exposure. While there exists extensive work on methods to best operationalize casefile records of maltreatment, such work has not been undertaken for youth self-reports, which are an important indicator of youth functioning following exposure. To address the lack of clarity of how to best operationalize youth self-reports of maltreatment, a multiverse analytic approach was taken to operationalize severity and frequency in a sample of 471 8- to 17-year-old children in foster care. We examined differences across measurement models and the models' associations with caregiver reports of youth suicidal ideation statements. Results indicate that the operationalizations used to define maltreatment resulted in differing measurement models that further differed in their associations with reports of youth suicidal ideation. This study highlights the importance of how researchers operationalize their data and the role dimensions of maltreatment have in further elucidating differential outcomes for youth exposed to maltreatment.

Annual Research Review: Mapping the multifaceted approaches and impacts of adverse childhood experiences - an umbrella review of meta-analyses

Adverse childhood experiences (ACEs) significantly impact lifelong health and well-being. Despite extensive research, a comprehensive understanding of ACEs' multifaceted impacts continues to be challenging to achieve. This study synthesizes meta-analytic evidence to provide a comprehensive view of ACEs' effects, addressing various approaches to conceptualizing ACEs and their diverse outcomes. Employing an umbrella synthesis methodology, this review integrated findings from 99 meta-analyses involving 592 effect sizes. We examined ACEs through specificity, lumping, dimensional, and child maltreatment-centric approaches, assessing their impact across six domains: biological system dysregulation, neuropsychological impairments, physical health complications, mental health conditions, social and behavioral challenges, and criminal justice involvement. The findings reveal a small to moderate overall effect size of ACEs across outcome domains. Specific ACE approaches exhibited varying impact levels, with notable differences in effects on mental health, social/behavioral issues, and criminal justice involvement. When ACEs were aggregated without distinguishing between different types, but with consideration of their cumulative effects, adverse outcomes were significantly exacerbated. The child maltreatment-centric approach consistently demonstrated substantial effects across all evaluated domains. This review underscores the heterogeneity in ACEs' impacts, influenced by the type of ACE and specific outcomes considered. It highlights the necessity for comprehensive approaches to understanding, preventing, and mitigating the effects of ACEs. These insights are vital for developing targeted interventions and informing policy-making, emphasizing the complexity and varied nature of ACEs' influence on individual development and societal well-being.

From Maltreatment to Psychiatric Disorders in Childhood and Adolescence: The Relevance of Emotional Maltreatment

Different forms of maltreatment are thought to incur a cumulative and non-specific toll on mental health. However, few large-scale studies draw on psychiatric diagnoses manifesting in early childhood and adolescence to identify sequelae of differential maltreatment exposures, and emotional maltreatment, in particular. Fine-grained multi-source dimensional maltreatment assessments and validated age-appropriate clinical interviews were conducted in a sample of N = 778 3 to 16-year-olds. We aimed to (a) substantiate known patterns of clinical outcomes following maltreatment and (b) analyse relative effects of emotional maltreatment, abuse (physical and sexual), and neglect (physical, supervisory, and moral-legal/educational) using structural equation modeling. Besides confirming known relationships between maltreatment exposures and psychiatric disorders, emotional maltreatment exerted particularly strong effects on internalizing disorders in older youth and externalizing disorders in younger children, accounting for variance over and above abuse and neglect exposures. Our data highlight the toxicity of pathogenic relational experiences from early childhood onwards, urging researchers and practitioners alike to prioritize future work on emotional maltreatment.

Children with sexual behavior problems: Ties to child maltreatment, family functioning, and help-seeking

Although the literature on children's sexual behavior problems (SBPs) has indicated that maltreatment and family dysfunction are linked to SBPs, several facets of these factors have remained unexamined. Prior research has largely focused on SBPs more broadly, though interpersonal SBPs (ISBPs) are likely a distinct, more severe SBP subtype. The aim of the current study was to examine potentially relevant, unexplored factors, including the number of types of and total allegations of maltreatment as well as familial characteristics (i.e., parenting attitudes and behaviors, discipline methods, family functioning, and help-seeking) in relation to SBPs and ISBPs. The present study included 8-year-old children (N = 1,011, 51.1% female, 53.8% Black) and their caregivers from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) study. In the model for SBPs, externalizing symptoms, the number of types of maltreatment allegations, maladaptive discipline methods, and help-seeking were associated with SBPs, whereas child's gender, race/ethnicity, internalizing symptoms, total maltreatment allegations, income, family functioning, and parenting attitudes were unrelated, r2 = .23. When ISBPs were examined, only child's gender and externalizing symptoms were tied to ISBPs, r2 = .09. However, child's race/ethnicity and internalizing symptoms, as well as maltreatment experiences, family factors, and help-seeking, were not associated with ISBPs. These findings highlight the importance of broader externalizing symptoms for both SBPs and ISBPs as well as the role of multiple types of maltreatment, parenting behavior, and help-seeking in the context of general SBPs.

Almost 2 years into the COVID-19 pandemic: an update on parental stress, parent mental health, and the occurrence of child maltreatment

Increased parental stress, poorer mental health, and an increase in the occurrence of child maltreatment (CM) have been reported in earlier phases of the COVID-19 pandemic. However, data from later phases of the pandemic are not yet available. We conducted a cross-sectional, representative survey among 1087 parents (48.8% female; mean age 41.72 years, SD = 9.15) in Germany in December 2021. Data were compared to a previous representative sample, assessed in August 2020 (N = 1024), and to normative scores of the outcome measures. Predictors for the occurrence of CM were analyzed by logistic regression. Pandemic-related stress and general stress were higher and physical and mental health were poorer in the December 2021 sample than in the August 2020 sample. Occurrence rates of CM varied between 5 and 56%. Verbal emotional abuse (n = 607, 56%), witnessing domestic violence (n = 446, 41%), and emotional neglect (n = 435, 40%) were most frequently reported. For these subtypes, parental risk for alcohol abuse (OR 2.1-2.7) and parental recent experience of violence (OR 2.1-5.1) were the strongest predictors. Across all subtypes of CM, parents reporting child maltreatment showed poorer scores on all stress outcomes, with medium-large-effect sizes. Results confirm a high burden within the families, almost 2 years into the pandemic. Occurrence rates of a broad spectrum of CM subtypes raise further concerns for the well-being of children. Family-oriented intervention efforts are needed to stabilize families and provide targeted support. Longitudinal studies are needed for a description of families at risk for poorer outcomes.

Subjective and objective experiences of childhood adversity: a meta-analysis of their agreement and relationships with psychopathology

BACKGROUND

Researchers use both subjective self-report and objective measures, such as official records, to investigate the impact of childhood adversity on psychopathology. However, it is unclear whether subjective and objective measures of childhood adversity (a) show agreement, and (b) differentially predict psychopathology.

METHOD

To address this, we conducted a pre-registered meta-analysis to examine the agreement between subjective and objective measures of childhood adversity, and their prediction of psychopathology. We searched in PubMed, PsycINFO and Embase for articles with both subjective measures (self-reports) and objective measures of childhood adversity (comprising official records, or reports from multiple informants unrelated to the target individual), and measures of psychopathology.

RESULTS

We identified 22 studies (n = 18,163) with data on agreement between subjective and objective measures of childhood adversities, and 17 studies (n = 14,789) with data on the associations between subjective and objective measures with psychopathology. First, we found that subjective and objective measures of childhood adversities were only moderately correlated (e.g. for maltreatment, r = .32, 95% CI = 0.23-0.41). Second, subjective measures of childhood adversities were associated with psychopathology, independent of objective measures (e.g. for maltreatment, r = .16, 95% CI = 0.09-0.22). In contrast, objective measures of childhood adversities had null or minimal associations with psychopathology, independent of subjective measures (e.g. r for maltreatment = .06, 95% CI = -0.02-0.13).

CONCLUSIONS

Our findings suggest that the effects of childhood adversity on psychopathology are primarily driven by a person's subjective experience. If this is the case, clinical interventions targeting memories and cognitive processes surrounding childhood adversity may reduce the risk of psychopathology in exposed individuals.

Psychological and Physical Abuse and Cortisol Response to Stress: The Moderating Role of Psychosocial Resources

Child abuse is associated with alterations in the hypothalamic-pituitary-adrenal (HPA) axis functioning. However, the unique effects of psychological and physical abuse and protective factors against these effects remain largely unknown. To close these gaps, the present study examined the unique effects of psychological and physical abuse on cortisol stress response and explored the moderating role of psychosocial resources in these associations among a sample of Chinese preadolescent children (N = 150; aged 9-13 years; M_age = 10.69 years; 51% boys). The results showed that both psychological and physical abuse were associated with blunted cortisol reactivity slopes. Psychological abuse, but not physical abuse, was associated with lower peak cortisol values and flatter cortisol recovery slopes. Further, psychosocial resources moderated the association between abuse and hyporesponsiveness of the HPA axis. The association between psychological abuse and lower peak cortisol values and the association between physical abuse and steeper cortisol recovery slopes (faster cortisol recovery following the stressor) were observed only among children with low levels of psychosocial resources. These findings indicate the differential effects of psychological and physical abuse on various phases of cortisol stress response, and the protective role of psychosocial resources. This study also has practical implications, given that preadolescence serves as a critical period for maximizing benefit of interventions of adversity.

Latent classes of child neglect types and associated characteristics

BACKGROUND

Children who experience neglect typically endure multiple types of neglect and abuse during a single maltreatment incident. However, research on the phenomenology and predictors of neglect types has primarily examined neglect types in isolation.

OBJECTIVE

To advance understanding of neglect incidents that more accurately reflect the experiences of children who have been neglected, we examined latent classes of neglect defined by co-occurring neglect types and multiple forms of abuse. To inform efforts to identify families at-risk for particular classes of neglect, associations between child, parent, and family characteristics and latent classes were examined.

PARTICIPANTS AND SETTING

390 child neglect incidents substantiated at U.S. Army installations.

METHODS

Neglect types and incident severity were coded using the Modified Maltreatment Classification System. Child, parent, and family characteristics were coded using information drawn from case records.

RESULTS

Latent class analysis yielded 5 classes: exposure to violence, failure to provide, supervisory lapses, substance-related endangerment, and non-specific. The exposure to violence and substance-related endangerment classes were characterized as highly severe. High and low severity classes were associated with distinct child, parent, and family characteristics. The latent classes were also differentiated by distal outcomes, including probability of law enforcement investigation, child removal from home, and offender removal from home.

CONCLUSIONS

By identifying the types of neglect and abuse that are likely to occur concomitantly as well as the child, parent, and family characteristics associated with increased risk of latent classes of neglect, results advance knowledge regarding the phenomenology of neglect types and inform prevention efforts.

Discrepancies between children's and caregivers' child maltreatment reporting and their associations with child wellbeing

BACKGROUND

Child maltreatment reporting is critical for case investigation and service disposition. However, reporting discrepancies across informants is a challenge for child welfare services.

METHODS

Using data from the Fragile Families and Child Wellbeing Study (n = 3150), the current study examined child-caregiver discrepancies in reporting the frequencies of psychological and physical maltreatment. Multivariate models were used to examine how caregivers' reports, children's reports, and discrepancies between the two were associated with child anxiety, depression, aggression, and delinquency.

RESULTS

A quarter of the children reported psychological maltreatment at a higher (25.7 %) or lower (23.8 %) frequency than their caregivers' report, respectively; 8.4 % and 8.7 % of the children did so in physical maltreatment reports, respectively. Multivariate models showed that children's maltreatment reports were more closely associated with children's anxiety, depression, and delinquency than caregivers' reports, while caregivers' reports were more closely associated with children's aggression. After accounting for caregivers' reporting and other covariates, children who reported more frequent psychological maltreatment than their caregivers' report had a higher level of anxiety, depression, and delinquency (b = 0.17 to 0.25, p < 0.001), and the opposite was true (b = -0.36 to -0.13, p < 0.001). Similarly, children who reported more frequent physical maltreatment than their caregivers' report had a higher level of all negative outcomes (b = 0.04 to 0.44; p = 0.04 to <0.00), and the opposite was true for aggression (b = -0.08, p = 0.004).

CONCLUSIONS

The findings suggest that in addition to other reporting barriers, children and caregivers may perceive maltreatment differently, and such discrepancies are related to children's wellbeing.

Discrepancies in youth self-report and case file report of maltreatment and association with internalizing and externalizing symptoms

BACKGROUND

Childhood maltreatment is a potential risk factor for the later development of psychopathology (Jaffee, 2017). However, there is no gold standard for identifying victims of child maltreatment, and when multiple informants - such as case files and youth self-report - are used, these sources often disagree (Cooley & Jackson, 2022).

OBJECTIVE

The current study aimed to explore discrepancies between youth self-report and case file report of maltreatment and examine how these discrepancies related to internalizing and externalizing symptoms.

PARTICIPANTS/SETTING

Participants were 470 youth living in foster care between the ages of 8 and 18 and their caregivers.

METHODS

Latent class analysis (LCA) was used to create novel groups based on informant discrepancies.

RESULTS

Agreement between informants was in the poor-to-fair agreement range for all types of maltreatment. Latent class analysis identified a 3-class solution with significant group differences on both externalizing (Χ² (2, N = 470) = 6.16, p = 0.05) and internalizing symptoms (Χ² (2, N = 470) = 6.10, p = 0.05). Specifically, those in the "self-report only" class had significantly higher symptoms than those in the "neither informant/case file only" class for both internalizing and externalizing behavior.

CONCLUSIONS

Case files and youth self-report of maltreatment are discrepant. Youth self-report of maltreatment history may be more closely linked to psychopathology than case file report of maltreatment. Researchers and practitioners should look to youth self-report rather than relying solely on case files when determining risk for psychopathology.

Immediate impact of child maltreatment on mental, developmental, and physical health trajectories

OBJECTIVE

The immediate impact of child maltreatment on health and developmental trajectories over time is unknown. Longitudinal studies starting in the direct aftermath of exposure with repeated follow-up are needed.

METHOD

We assessed health and developmental outcomes in 6-month intervals over 2 years in 173 children, aged 3-5 years at study entry, including 86 children with exposure to emotional and physical abuse or neglect within 6 months and 87 nonmaltreated children. Assessments included clinician-administered, self- and parent-report measures of psychiatric and behavioral symptoms, development, and physical health. Linear mixed models and latent growth curve analyses were used to contrast trajectories between groups and to investigate the impact of maltreatment features on trajectories.

RESULTS

Maltreated children exhibited greater numbers of psychiatric diagnoses (b = 1.998, p < .001), externalizing (b = 13.29, p < .001) and internalizing (b = 11.70, p < .001) symptoms, impairments in cognitive (b = -11.586, p < .001), verbal (b = -10.687, p < .001), and motor development (b = -7.904, p = .006), and greater numbers of medical symptoms (b = 1.021, p < .001) compared to nonmaltreated children across all time-points. Lifetime maltreatment severity and/or age at earliest maltreatment exposure predicted adverse outcomes over time.

CONCLUSION

The profound, immediate, and stable impact of maltreatment on health and developmental trajectories supports a biological embedding model and provides foundation to scrutinize the precise underlying mechanisms. Such knowledge will enable the development of early risk markers and mechanism-driven interventions that mitigate adverse trajectories in maltreated children.

Emotional maltreatment and neglect impact neural activation upon exclusion in early and mid-adolescence: An event-related fMRI study

Child maltreatment gives rise to atypical patterns of social functioning with peers which might be particularly pronounced in early adolescence when peer influence typically peaks. Yet, few neuroimaging studies in adolescents use peer interaction paradigms to parse neural correlates of distinct maltreatment exposures. This fMRI study examines effects of abuse, neglect, and emotional maltreatment (EM) among 98 youth (n = 58 maltreated; n = 40 matched controls) using an event-related Cyberball paradigm affording assessment of both social exclusion and inclusion across early and mid-adolescence (≤13.5 years, n = 50; >13.5 years, n = 48). Younger adolescents showed increased activation to social exclusion versus inclusion in regions implicated in mentalizing (e.g., superior temporal gyrus). Individual exposure-specific analyses suggested that neglect and EM coincided with less reduction of activation to social exclusion relative to inclusion in the dorsal anterior cingulate cortex/pre-supplementary motor area (dACC/pre-SMA) among younger versus older adolescents. Integrative follow-up analyses showed that EM accounted for this dACC/pre-SMA activation pattern over and above other exposures. Moreover, age-independent results within respective exposure groups revealed that greater magnitude of neglect predicted blunted exclusion-related activity in the parahippocampal gyrus, while EM predicted increased activation to social exclusion in the precuneus/posterior cingulate cortex.

Heterogeneity in caregiving-related early adversity: Creating stable dimensions and subtypes

Early psychosocial adversities exist at many levels, including caregiving-related, extrafamilial, and sociodemographic, which despite their high interrelatedness may have unique impacts on development. In this paper, we focus on caregiving-related early adversities (crEAs) and parse the heterogeneity of crEAs via data reduction techniques that identify experiential cooccurrences. Using network science, we characterized crEA cooccurrences to represent the comorbidity of crEA experiences across a sample of school-age children (n = 258; 6-12 years old) with a history of crEAs. crEA dimensions (variable level) and crEA subtypes (subject level) were identified using parallel factor analysis/principal component analysis and graph-based Louvain community detection. Bagging enhancement with cross-validation provided estimates of robustness. These data-driven dimensions/subtypes showed evidence of stability, transcended traditional sociolegally defined groups, were more homogenous than sociolegally defined groups, and reduced statistical correlations with sociodemographic factors. Finally, random forests showed both unique and common predictive importance of the crEA dimensions/subtypes for childhood mental health symptoms and academic skills. These data-driven outcomes provide additional tools and recommendations for crEA data reduction to inform precision medicine efforts in this area.

Informant Discrepancies in Child Maltreatment Reporting: A Systematic Review

Potential informants on child maltreatment include the youth who has experienced the alleged maltreatment, and the youth's caregivers, social workers and case files. When multiple informants are compared, they often disagree about whether or not a youth has experienced maltreatment. Such determinations are critical as endorsement-or lack of endorsement-of maltreatment can have significant consequences on the child's safety, future living arrangements and referral for treatment and services. The current study provides a systematic review of the literature on informant discrepancies in child maltreatment. Three databases-PsychINFO, Web of Science, and PubMed-were used to identify studies for the review and 13 articles met inclusion criteria. Results showed that more youth tend to report physical, sexual and emotional abuse than seen in case files. By contrast, more case files include neglect than reported by youth. Implications and future directions are discussed.

Adverse childhood experiences (ACEs) relate to blunted cardiovascular and cortisol reactivity to acute laboratory stress: A systematic review and meta-analysis

Adverse childhood experiences (ACEs) are associated with poor future mental and physical health. Altered biological reactivity to mental stress may be a possible mechanism linking ACEs to poor health. However, it is not clear if ACEs relate to blunted or exaggerated stress reactivity. This meta-analysis aimed to determine whether exposure to ACEs is associated with cardiovascular and cortisol stress reactivity. A systematic review yielded 37 sources. Random-effects modelling tested the aggregate effects of 83 studies of the association between ACEs and stress reactivity. Exposure to ACEs was associated with relatively blunted cardiovascular and cortisol stress reactivity. Effect sizes did not vary as a function of sample sex or reactivity measure (e.g., heart rate, blood pressure, or cortisol). Meta-regression revealed preliminary evidence of greater blunting in samples of a younger age and samples reporting greater ACE exposure. Subgroup analyses for stress task, ACE measurement instrument, and sample race were not conducted because of a lack of between-study variability. Exposure to ACEs is associated with dysregulation of multiple components of the human stress response system.

Child Abuse Potential in Young German Parents: Predictors, Associations with Self-reported Maltreatment and Intervention Use

Since child maltreatment has highly negative effects on child adjustment, early identification of at-risk families is important. This study focuses on longitudinal risk factors for child maltreatment and associations between abuse risk and occurrence. It also examines whether abuse risk and involvement in early childhood intervention are associated. The sample comprises 197 German caregivers with children under 3 years of age. Data was collected in two waves. The Brief Child Abuse Potential Inventory assessed abuse risk. Socio-demographic, parent, child and family-related risk factors were measured using screening tools. The analysis revealed that parental characteristics (psychopathology, own maltreatment experiences etc.) were associated with concurrent abuse risk. Longitudinal changes in abuse risk were linked to caregiver education and child-related factors. Cumulative risk did not explain more variance than specific risk factors. Significant associations with caregiver-reported abuse were found, and data suggest that some burdened families cannot be reached by early childhood intervention.

Threat-specific maltreatment exposure: Comparison of measurement models and associations with internalizing, externalizing, and PTSD symptoms

BACKGROUND

Child maltreatment is associated with short- and long-term mental health sequelae. Extant research has demonstrated that exposure characteristics (i.e., severity, frequency, duration, onset) are important in the measurement of maltreatment experiences. Emerging research has highlighted the contributions of these characteristics on symptom outcomes.

OBJECTIVE

The current study used multiple exposure characteristics of threat-specific types of maltreatment (i.e., physical abuse, sexual abuse, witnessing domestic violence) to examine three distinct measurement models of maltreatment and their relation to symptoms.

PARTICIPANTS AND SETTING

A racially and ethnically diverse sample of treatment-seeking youth (74 % female) ages 4-17 (N = 348) participated in the study. The majority of the youth (61 %) endorsed experiencing more than one type of threat-specific maltreatment.

METHOD

Using Structural Equation Modeling, we tested one-factor, three-factor, and bifactor models of maltreatment characteristics, and hypothesized that the bifactor model would yield the best fitting model based on prior studies supporting family violence as an underlying factor for child physical abuse and domestic violence.

RESULTS

The bifactor measurement model fit the data better than the three- and one-factor models. In the bifactor structural model that included symptom outcomes, physical abuse was significantly and positively associated with child internalizing and externalizing symptoms, whereas sexual abuse and witnessing domestic violence were associated with externalizing symptoms and PTSD.

CONCLUSION

Our findings support the inclusion of multiple exposure characteristics in the measurement of maltreatment and suggest that specific types of threat-specific maltreatment may have distinct associations with mental health sequelae.

Stress-elicited neural activity in young adults varies with childhood sexual abuse

OBJECTIVE

Childhood physical and sexual abuse are stressful experiences that may alter the emotional response to future stressors. Stress-related emotional function is supported by brain regions that include the prefrontal cortex (PFC), hippocampus, and amygdala. The present study investigated whether childhood physical and sexual abuse are associated with stress-elicited brain activity in young adulthood.

METHODS

Participants (N = 300; Mage = 20.0; 151 female) completed a psychosocial stress task during functional magnetic resonance imaging (fMRI). Measures of physical and sexual abuse were included in a linear mixed effects model to estimate the unique relationship each type of childhood abuse had with stress-elicited brain activity.

RESULTS

Stress-elicited dorsolateral PFC, ventromedial PFC, and hippocampal activity decreased as the frequency of childhood sexual abuse increased. There were no regions in which stress-elicited activation varied with physical abuse.

CONCLUSIONS

The present findings suggest there is a unique relationship between childhood sexual abuse and the stress-elicited PFC and hippocampal activity of young adults that is not observed following childhood physical abuse.

SIGNIFICANCE

These findings may have important implications for understanding the mechanisms by which childhood sexual abuse impacts the development of future psychopathology.

The Family Nurse Partnership to reduce maltreatment and improve child health and development in young children: the BB:2–6 routine data-linkage follow-up to earlier RCT

Background

The short-term effectiveness (to 24 months post partum) of a preventative home-visiting intervention, the Family Nurse Partnership, was previously assessed in the Building Blocks trial (BB:0–2).

Objectives

The objectives were to establish the medium-term effectiveness of the Family Nurse Partnership in reducing maltreatment and improving maternal health (second pregnancies) and child health, developmental and educational outcomes (e.g. early educational attendance, school readiness); to explore effect moderators and mediators; and to describe the costs of enhancing usually provided health and social care with the Family Nurse Partnership.

Design

Children and their mothers from an existing trial cohort were followed up using routine data until the child was 7 years of age.

Setting

This study was set in 18 partnerships between local authorities and health-care organisations in England.

Participants

The participants were mothers [and their firstborn child(ren)] recruited as pregnant women aged ≤ 19 years, in local authority Family Nurse Partnership catchment areas, at < 25 weeks’ gestation, able to provide consent and able to converse in English. Participants mandatorily withdrawn (e.g. owing to miscarriage) from the BB:0–2 trial were excluded.

Interventions

The intervention comprised up to a maximum of 64 home visits by specially trained family nurses from early pregnancy until the firstborn child was 2 years of age, plus usually provided health and social care support. The comparator was usual care alone.

Main outcome measures

The primary outcome measure was child-in-need status recorded at any time during follow-up. The secondary outcomes were as follows: (1) referral to social services, child protection registration (plan), child-in-need categorisation, looked-after status, recorded injuries and ingestions at any time during follow-up; (2) early child care and educational attendance, school readiness (Early Years Foundation Stage Profile score) and attainment at Key Stage 1; and (3) health-care costs.

Data sources

The following data sources were used: maternally reported baseline and follow-up data (BB:0–2), Hospital Episode Statistics data (NHS Digital), social care and educational data (National Pupil Database) and abortions data (Department of Health and Social Care).

Results

There were no differences between study arms in the rates of referral to social services, being registered as a child in need, receiving child protection plans, entering care or timing of first referral for children subsequently assessed as in need. There were no differences between study arms in rates of hospital emergency attendance, admission for injuries or ingestions, or in duration of stay for admitted children. Children in the Family Nurse Partnership arm were more likely to achieve a good level of development at reception age (school readiness), an effect strengthened when adjusting for birth month. Differences at Key Stage 1 were not statistically different, but, after adjusting for birth month, children in the Family Nurse Partnership arm were more likely to reach the expected standard in reading. Programme effects were greater for boys (Key Stage 1: writing); children of younger mothers (Key Stage 1: writing, Key Stage 1: mathematics); and children of mothers not in employment, education or training at study baseline (Key Stage 1: writing). There were no differences between families who were part of the Family Nurse Partnership and those who were not for any other outcome. The differences between study arms in resource use and costs were negligible.

Limitations

The outcomes are constrained to those available from routine sources.

Conclusions

There is no observable benefit of the programme for maltreatment or maternal outcomes, but it does generate advantages in school readiness and attainment at Key Stage 1.

Future work

The trajectory of longer-term programme benefits should be mapped using routine and participant-reported measures.

[Assessment of Maltreatment in Childhood and Adolescence]

Assessment of Maltreatment in Childhood and Adolescence In view of mounting evidence for substantial prognostic relevance of child maltreatment for the future developmental course, assessment of maltreatment in children and adolescents is increasingly gaining attention. At the same time, maltreatment assessment is replete with difficulties, ranging from the definition of maltreatment and establishment of threshold values determining when events meet prognostically relevant criteria, to poor agreement between sources. The aim of this paper is to provide an overview of instruments for assessing maltreatment in children and adolescents. This overview serves as a point of departure to emphasize the importance of various sources for the purpose of assessing maltreatment and to consider the unique role of the child's or young person's perspective. We conclude with preliminary proposals regarding the role of maltreatment assessment in clinical practice.

Association between childhood trauma and brain anatomy in women with post-traumatic stress disorder, women with borderline personality disorder, and healthy women

BACKGROUND

Childhood trauma (CT) is associated with altered brain anatomy. These neuroanatomical changes might be more pronounced in individuals with a psychiatric disorder. Post-traumatic stress disorder (PTSD) and borderline personality disorder (BPD) are more prevalent in individuals with a history of CT.

OBJECTIVE

In this study, we examined limbic and total brain volumes in healthy women with and without a history of CT and in females with PTSD or BPD and a history of CT to see whether neuroanatomical changes are a function of psychopathology or CT.

METHOD

In total, 128 women (N = 70 healthy controls without CT, N = 25 healthy controls with CT, N = 14 individuals with PTSD, and N = 19 individuals with BPD) were recruited. A T1-weighted anatomical MRI was acquired from all participants for Freesurfer-based assessment of total brain, hippocampus, and amygdala volumes. Severity of CT was assessed with a clinical interview and the Childhood Trauma Questionnaire. Group differences in hippocampal and amygdala volumes (adjusted for total brain volume) and total brain volume (adjusted for height) were characterized by analysis of covariance.

RESULTS

Volume of the total brain, hippocampus, and amygdala did not differ between the four groups (p > .05). CT severity correlated negatively with total brain volume across groups (r = -0.20; p = .029).

CONCLUSIONS

CT was associated with reduced brain volume but PTSD or BPD was not. The association between CT and reduced brain volume as a global measure of brain integrity suggests a common origin for vulnerability to psychiatric disorders later in life.

Childhood Adversities as Determinants of Cardiovascular Disease Risk and Perceived Illness Burden in Adulthood: Comparing Retrospective and Prospective Self-Report Measures in a Longitudinal Sample of African Americans

A large body of evidence suggests that exposure to childhood adversities increases risk for poor quality physical health in adulthood. Much of this evidence is based on retrospective measures which are believed to be contaminated by the limitations and biases of autobiographical memory. Using longitudinal data on 454 African Americans (61 percent female) this study examines the corroboration between prospective and retrospective measures of childhood adversities gathered approximately two decades apart, and the relative ability of the measures to predict self-reported illnesses and a biomarker of 30-year cardiovascular disease risk. Comparisons indicated that the retrospective and prospective measures demonstrated weak convergence and did not provide completely equivalent information about self-reported adverse childhood experiences. A series of regression models indicated that the two measures of adversities exhibited similar associations with the cardiovascular disease biomarker but divergent associations with self-reported illnesses. Furthermore, both the prospective and retrospective measures simultaneously predicted cardiovascular disease risk in adulthood. That the prospective measure did not significantly predict perceived illnesses after adjusting for the retrospective measure is evidence that childhood adversities predict self-reported health burden insofar as respondents remember those adversities as adults. The findings provide evidence that retrospective self-report measures of childhood adversities do not closely converge with prospective measures, and that retrospective measures may not provide valid estimates of the association between childhood adversities and perceived illnesses in adulthood.

Intergenerational transmission of child maltreatment using a multi-informant multi-generation family design

In the current study a three-generational design was used to investigate intergenerational transmission of child maltreatment (ITCM) using multiple sources of information on child maltreatment: mothers, fathers and children. A total of 395 individuals from 63 families reported on maltreatment. Principal Component Analysis (PCA) was used to combine data from mother, father and child about maltreatment that the child had experienced. This established components reflecting the convergent as well as the unique reports of father, mother and child on the occurrence of maltreatment. Next, we tested ITCM using the multi-informant approach and compared the results to those of two more common approaches: ITCM based on one reporter and ITCM based on different reporters from each generation. Results of our multi-informant approach showed that a component reflecting convergence between mother, father, and child reports explained most of the variance in experienced maltreatment. For abuse, intergenerational transmission was consistently found across approaches. In contrast, intergenerational transmission of neglect was only found using the perspective of a single reporter, indicating that transmission of neglect might be driven by reporter effects. In conclusion, the present results suggest that including multiple informants may be necessary to obtain more valid estimates of ITCM.

Dimensionality of Early Adversity and Associated Behavioral and Emotional Symptoms: Data from a Sample of Japanese Institutionalized Children and Adolescents

Recent approaches have begun to identify common variance across co-occurring childhood adversities (CAs) and their associations with symptoms of psychopathology. However, few studies have investigated these questions in high-risk samples, and in different cultural contexts. This study examined common variance amongst 18 types of CAs and associated symptomatology in 457 children and adolescents living in 24 residential homes in Japan. Principal component analysis identified four significant components that explained 35.1% of the variance: parental abuse, parental psychosocial risks, parental absence, and parental neglect. Path analysis revealed general as well as differential associations with negative outcomes: parental abuse, parental neglect, and parental psychosocial risks significantly associated with conduct problems, whereas parental abuse uniquely associated with peer problems, and parental neglect with hyperactivity/inattention. As well as confirming prior knowledge, these findings also extended understanding of these associations to a new cultural context. Future studies should take into account the multidimensional nature when assessing CAs.

The genetic and environmental etiology of child maltreatment in a parent-based extended family design

Child maltreatment has been associated with various cumulative risk factors. However, little is known about the extent to which genetic and environmental factors contribute to individual differences between parents in perpetrating child maltreatment. To estimate the relative contribution of genetic and environmental factors to perpetrating maltreatment we used a parent-based extended family design. Child-reported perpetrated maltreatment was available for 556 parents (283 women) from 63 families. To explore reporter effects (i.e., child perspective on maltreatment), child reports were compared to multi-informant reports. Based on polygenic model analyses, most of the variance related to the perpetration of physical abuse and emotional neglect was explained by common environmental factors (physical abuse: c2 = 59%, SE = 12%, p = .006; emotional neglect: c2 = 47%, SE = 8%, p &lt; .001) whereas genetic factors did not significantly contribute to the model. For perpetrated emotional abuse, in contrast, genetic factors did significantly contribute to perpetrated emotional abuse (h2 = 33%, SE = 8%, p &lt; .001), whereas common environment factors did not. Multi-informant reports led to similar estimates of genetic and common environmental effects on all measures except for emotional abuse, where a multi-informant approach yielded higher estimates of the common environmental effects. Overall, estimates of unique environment, including measurement error, were lower using multi-informant reports. In conclusion, our findings suggest that genetic pathways play a significant role in perpetrating emotional abuse, while physical abuse and emotional neglect are transmitted primarily through common environmental factors. These findings imply that interventions may need to target different mechanisms dependings on maltreatment type.

Getting less than their fair share: Maltreated youth are hyper-cooperative yet vulnerable to exploitation in a public goods game

Human cooperative behavior has long been thought to decline under adversity. However, studies have primarily examined perceived patterns of cooperation, with little eye to actual cooperative behavior embedded within social interaction. Game-theoretical paradigms can help close this gap by unpacking subtle differences in how cooperation unfolds during initial encounters. This study is the first to use a child-appropriate, virtual, public goods game to study actual cooperative behavior in 329 participants aged 9-16 years with histories of maltreatment (n = 99) and no maltreatment (n = 230) while controlling for psychiatric symptoms. Unlike work on perceived patterns of cooperation, we found that maltreated participants actually contribute more resources to a public good during peer interaction than their nonmaltreated counterparts. This effect was robust when controlling for psychiatric symptoms and peer problems as well as demographic variables. We conclude that maltreatment may engender a hyper-cooperative strategy to minimize the odds of hostility and preserve positive interaction during initial encounters. This, however, comes at the cost of potential exploitation by others.
