Childhood Maltreatment and Impulsivity: A Meta-Analysis and Recommendations for Future Study

Parent Physical and Psychological Aggression and Youth Dating Violence: A Latent Class Analysis Approach

Adolescent dating violence is a national public health issue and research suggests that aggressive parenting may predict the likelihood that a child will subsequently experience abuse. The purpose of this study is to examine the effect of parent physical and psychological aggression on adolescent dating violence perpetration and victimization. Data derived from the Future of Families and Child Wellbeing Study resulted in a racially and ethnically diverse sample of adolescents in dating relationships at the age of 15 years (N = 952). Utilizing both parent and adolescent data which assessed parenting practices at ages 3, 5, 9, and 15, and adolescent dating violence victimization and perpetration at age 15, we analyzed the data using a latest class analysis. Youth were typologized into three classes: the non-physically aggressive parenting, nonaggressive dating class (Class 1; 16% of youth), the aggressive parenting, nonaggressive dating class (Class 2; 76% of youth), and the aggressive parenting, aggressive dating class (Class 3; 8% of youth). Parents across all three classes utilized high levels of psychologically aggressive parenting. An important finding from this study is that parents' use of both physically and psychologically aggressive parenting only predicted subsequent dating violence victimization and perpetration among a small portion of adolescents. Findings suggest that additional risk factors, including household income and adolescent impulsivity, may help to elucidate pathways to adolescent dating violence. There is also a need to further explore the resiliency factors at play for youth who, despite having experienced both psychologically and physically aggressive parenting across the lifespan, did not experience dating violence victimization or perpetration.

Does Childhood Trauma Predict Impulsive Spending in Later Life? An Analysis of the Mediating Roles of Impulsivity and Emotion Regulation

We sought to investigate whether adverse childhood experiences increase impulsive spending in later life, and whether emotion dysregulation and impulsivity mediate this association. Limited research has examined associations between these factors, and examining the mechanisms involved may inform interventions for impulsive spending. This study used a cross-sectional, correlational design including 189 adult participants who completed an online survey assessing childhood trauma, adverse childhood experiences, impulsive spending, impulsivity, and emotion dysregulation. Greater adverse childhood experiences and childhood trauma were positively correlated with impulsive spending, as well as general impulsivity and emotion dysregulation. Mediation analyses indicated that emotion dysregulation and greater impulsivity accounted for the positive relationship between childhood trauma and impulse spending. Adverse childhood experiences and childhood trauma are associated with increased risk of impulse spending in adulthood via elevated general impulsivity and emotion dysregulation.

Child maltreatment and psycho-social impairments among child laborers in rural Bangladesh

PURPOSE

The current study focused on exploring the impact of maltreatment of child laborers on their psychosocial health condition from the views of their parents.

METHODS

A total of 100 parents of child laborers were recruited using snowball sampling. The structured questionnaire comprised two validated scales including ISPCAN Child Abuse Screening Tool (ICAST-P), and Paediatric Symptom Checklist (PSC) were used for the survey. Factor analysis and multivariable linear regression analysis were performed to examine the data using SPSS version 26, and Stata version 16.1.

RESULTS

A three-factor model consisting of internalizing, externalizing, and attention associated psycho-social impairments of child laborers were derived from the 35-item scale of PSC tool and represented a good fit to the data. A mean estimate of maltreatment indicates that a majority of child laborers are maltreated psychologically, followed by physical maltreatment and neglect. The factor analysis resulted that maltreated child laborers are highly prone to exhibit internalized psycho-social difficulties, followed by externalized and attention-associated emotional and behavioral difficulties among child laborers. The regression model further depicts that child laborers, who had been physically and psychologically maltreated, are significantly more likely to be affected by internalized and attention-related psycho-social impairments.

CONCLUSIONS

The study concluded that victimized child laborers exhibited significant internalized, as well as attention-related problems. These findings may be useful for future studies that examine emotional and behavioral problems among maltreated child laborers and, therefore, for developing prevention strategies.

Child sexual abuse and its determinants among children in Addis Ababa Ethiopia: Systematic review and meta-analysis

Child sexual abuse is a significant public health concern and a breach of basic human rights affecting millions of children each year globally. It is typically not reported by victims, hence it remains usually concealed. Except for single studies with varying reports, there is no national studies conducted on child sexual abuse in Ethiopia. Therefore, this review determined the pooled magnitude and determinants of sexual abuse among children in Ethiopia. Potential articles were searched from PubMed, Science Direct, Scopus, and Web of science using relevant searching key terms. The Joanna Briggs Institute (JBI) critical appraisal checklist was used to evaluate the quality of all selected articles. Data were analyzed using STATA Version 14 software. Publication bias was checked using Egger's test and funnel plot. Cochran's chi-squared test and I2 values were used to assess heterogeneity. A random-effects model was applied during meta-analysis. The pooled prevalence of sexual abuse among 5,979 children in Ethiopia was 41.15% (95% CI: 24.44, 57.86). Sex of children (OR: 2.14, 95%CI: 1.12, 4.06), smoking (OR: 4.48, 95%CI: 1.26, 76.79), khat chewing (OR: 3.68, 95%CI: 1.62, 21.93), and alcohol use (OR: 4.77, 95%CI: 2.22, 10.25) were the determinants of child sexual abuse. The main perpetrators of sexual abuse against children were neighbors, boy/girlfriends, family members, school teachers, and stranger person. Child sexual abuse commonly took place in the victim's or perpetrator's home, school, and neighbor's home. This review revealed that the magnitude of child sexual abuse in Ethiopia was relatively high and multiple factors determined the likelihood of sexual violence against children. Thus, policy-makers and concerned stakeholders should strengthen comprehensive sexual and reproductive health education to reduce the magnitude and consequences of child sexual abuse. Moreover, support with special attention should be given to children with mental illness and physical disabilities.

A hamster model for stress-induced weight gain

This review addresses the translational relevance of animal models of stress and their effects on body weight. In humans, stress, whether chronic or acute, has often been associated with increased food intake and weight gain. In view of the current obesity epidemic, this phenomenon is especially relevant. Such observations contrast with reports with commonly used laboratory animals, especially rats and mice. In these species, it is common to find individuals gaining less weight under stress, even with potent social stressors. However, there are laboratory species that present increased appetite and weight gain under stress, such as golden hamsters. Furthermore, these animals also include metabolic and behavioral similarities with humans, including hoarding behavior which is also enhanced under stress. Consequently, we propose that our comparative perspective provides useful insights for future research on the development of obesity in humans as a consequence of chronic stress exposure.

Serial mediating effects of childhood trauma and conduct behaviors on the impact of family history among patients with alcohol use disorder

Family history (FH) of alcoholism increases the risk of alcohol use disorder (AUD); however, the contribution of childhood trauma (CT) in this respect remains unclear. This study investigated the relationship between FH and AUD-related clinical characteristics (social onset, antisocial tendency, and severity of problematic alcohol consumption) through the mediating effects of childhood trauma (CT) and conduct behaviors (CB) in a Korean male population with AUD. A total of 304 patients hospitalized for AUD at 16 psychiatric hospitals completed standardized questionnaires, including self-rated scales. Mediation analyses were performed using the SPSS macro PROCESS. Individuals with positive FH (133, 44%) had greater CT and CB and more severe AUD-related clinical characteristics than those without FH (171, 56%). In the present serial mediation model, FH had significant direct and indirect effects on AUD-related clinical characteristics through CT and CB. Indirect effects were 21.3% for social onset, 46.3%, antisocial tendency, and 37.9% for problematic drinking. FH directly contributed to AUD-related clinical characteristics, and CT and CB played mediating roles. This highlights the importance of careful intervention and surveillance of adverse childhood experiences and conduct disorder to prevent and mitigate alcohol-related problems in individuals with FH of AUD.

Childhood emotional maltreatment and sensitivity to social rejection in emerging adults

BACKGROUND

Enhanced responsiveness to social rejection may be a transdiagnostic mechanism through which childhood emotional maltreatment predisposes individuals to interpersonal and mental health problems. To investigate this mechanism, as a first step, more detailed investigations are needed regarding the assumed association of childhood emotional maltreatment with rejection sensitivity in later life.

OBJECTIVE

The present work examines the hypothesis that among different subtypes of childhood maltreatment, in particular forms of emotional maltreatment (emotional abuse and neglect) relate to rejection sensitivity in emerging adults.

PARTICIPANTS AND SETTING

In study 1, 311 emerging adults (18-25 years) participated in a retrospective cross-sectional assessment. In study 2, 78 emerging adults (18-25 years) were included in an experiment (O-Cam paradigm) which involved the experience of social rejection (vs. inclusion).

METHODS

Study 1 investigates whether intensities of childhood emotional abuse and neglect have unique associations with trait rejection sensitivity, when considering all maltreatment subtypes (emotional abuse, sexual abuse, physical abuse, emotional neglect, physical neglect) simultaneously. Study 2 examined whether childhood emotional abuse and neglect moderate the experience of social rejection in terms of need depletion, sadness and anger after social rejection (vs. inclusion).

RESULTS

Study 1 indicates that emotional abuse and neglect have unique associations with rejection sensitivity. Study 2 results show that only a higher intensity of emotional abuse has extensive effects on need depletion and sadness after social rejection (vs. inclusion).

CONCLUSIONS

In particular, experiences of childhood emotional abuse may relate to rejection sensitivity in young adulthood.

Dimensional model of adolescent personality pathology, reflective functioning, and emotional maltreatment

Introduction

Childhood emotional abuse (CEA) is a recognized risk factor for adolescent mentalizing challenges. However, there's limited understanding about how CEA might influence personality development and elevate the risk of adolescent personality pathology. A deeper grasp of these pathways is crucial, given that adolescence is a pivotal developmental phase for identity integration, personality consolidation, and the emergence of personality disorders. As the emphasis shifts to dimensional perspectives on adolescent personality pathology, the spotlight is increasingly on adolescents' evolving personality organization (PO). Within this framework, personality disorder manifestations stem from inherent vulnerabilities in PO. A comprehensive understanding of how CEA leads to these inherent vulnerabilities in PO can inform enhanced interventions for at-risk adolescents. Nonetheless, our comprehension lacks insight into potential pathways to PO, especially those involving external factors like maltreatment and individual traits like mentalizing. This study sought to bridge these gaps by employing latent factor analysis and structural equation modeling to explore connections between emotional maltreatment, adolescent mentalizing, and PO.

Methods

A community-based cohort of 193 adolescents (aged 12-17) took part in self-report assessments: the Childhood Experience of Care and Abuse Questionnaire (CECA.Q), the Reflective Functioning Questionnaire for Youth (RFQ-Y), and the Inventory for Personality Organization for Adolescents (IPO-A).

Results

The structural equation model revealed a significant direct influence of CEA on both RFQ-Confusion and PO, and a noteworthy direct effect of RFQ-Confusion on PO. Remarkably, the model accounted for 76.9% of the PO variance. CEA exhibited a significant indirect impact on PO through RFQ-Confusion, which was accountable for 52.3% of the CEA effect on PO, signifying a partial mediation by mentalizing.

Discussion

These insights carry substantial clinical implications, especially for devising integrated, trauma-informed strategies for adolescents with personality pathologies. This is particularly relevant for enhancing mentalizing and bolstering personality consolidation among adolescent CEA survivors.

Non-offending caregivers reflections on the use of a film encompassing child sexual abuse perpetrator's testimonies for potential child protection initiatives in South Africa

BACKGROUND

Child sexual abuse (CSA) remains a challenge in South Africa, despite various legislative developments to address child abuse. Despite non-offending caregivers (NOC) playing a critical role in child safeguarding, and supporting disclosure and recovery, very little research has focused on understanding what works in assisting them in supporting child victims in South Africa.

OBJECTIVES

The study examines the exposure of NOC who watched a short film based on the testimonies of four CSA perpetrators in therapy, with a view to exploring whether this film could be useful for CSA prevention, disclosure and support initiatives.

PARTICIPANTS AND SETTING

A convenience sample of eight NOC attending a community support service in KwaZulu-Natal, South Africa.

METHODS

After viewing the film, the NOC completed a questionnaire, and were asked to discuss usefulness of film content based on perpetrator testimonials in sensitizing NOC around disclosure of sexual abuse and support of the child. Thematic data analysis combined their perceptions of sexual abuse experienced by their children/grandchildren and the effect that content of the film had on their perceptions.

RESULTS

Five themes emerged; Awareness of CSA and available child protection programs; Views toward CSA disclosure; Emotive responses; Lessons learnt for identification of CSA and child protection; and Recommendations for future programs.

CONCLUSIONS

The process of viewing and discussing the film stimulated a shift for NOC to identify risk, facilitate disclosure of CSA, and become more supportive toward child victims. The study highlights the potential of using film to guide NOC targeted child protection and safeguarding initiatives.

Childhood maltreatment and adulthood victimization: An evidence-based model

There is ample evidence showing that childhood maltreatment increases two to three fold the risk of victimization in adulthood. Various risk factors, including posttraumatic stress disorder (PTSD) symptoms, dissociation, self-blame, and alcohol abuse are related to revictimization. Although previous research examined associations between risk factors for revictimization, the evidence is limited and the proposed models mostly include a handful of risk factors. Therefore, it is critical to investigate a more comprehensive model explaining the link between childhood maltreatment and adulthood (re)victimization. Accordingly, this study tested a data-driven theoretical path model consisting of 33 variables (and their associations) that could potentially enhance understanding of factors explaining revictimization. Cross-sectional data derived from a multi-wave study were used for this investigation. Participants (N = 2156, age mean = 19.94, SD = 2.89) were first-year female psychology students in the Netherlands and New Zealand, who responded to a battery of questionnaires and performed two computer tasks. The path model created by structural equation modelling using modification indices showed that peritraumatic dissociation, PTSD symptoms, trauma load, loneliness, and drug use were important mediators. Attachment styles, maladaptive schemas, meaning in life, and sex motives connected childhood maltreatment to adulthood victimization via other factors (i.e., PTSD symptoms, risky sex behavior, loneliness, emotion dysregulation, and sex motives). The model indicated that childhood maltreatment was associated with cognitive patterns (e.g., anxious attachment style), which in turn were associated with emotional factors (e.g., emotion dysregulation), and then with behavioral factors (e.g., risky sex behavior) resulting in revictimization. The findings of the study should be interpreted in the light of the limitations. In particular, the cross-sectional design of the study hinders us from ascertaining that the mediators preceded the outcome variable.

Maltreatment of child labourers in Bangladesh: Prevalence and characteristics of perpetrators

Background

Child labourers are highly prone to maltreatment mostly perpetrated by members of their immediate family as well as employers and co-workers. This maltreatment is considered to be a serious public health issue. However, little is known about this form of violence.

Purpose

This study aimed to explore the views of key informants on the prevalence and attributes of perpetrators of the maltreatment of child labourers in Bangladesh.

Methods

The key experts were paediatricians, journalists, academics, and government bureaucrats such as policy makers and Non-Government Organisation employees working in the area of child abuse or labour relations. Interviews were purposefully conducted via TEAMS with 17 expert participants. A thematic analysis using NVivo was used to analyse the data.

Results

The key informants were of the opinion that the prevalence of the maltreatment of child labourers was unknown. However, they were of the view that physical maltreatment of child labourers occurred between 70% and 100% of the time, while emotional abuse and neglect was estimated to be 100% followed by 50% for financial exploitation. Child maltreatment is more likely to occur in informal workplace environments. Biological and foster parents were considered the primary perpetrators, while employers and adult co-workers were considered secondary perpetrators. Perpetrators of child labour maltreatment were often characterized as having a history of childhood maltreatment themselves, a lack of knowledge of social awareness and parenting, and suffer from economic difficulties.

Conclusion

The finding also calls into question the validity of key informant interviewing. Only the journalists, academics and medical experts had first-hand knowledge of the maltreatment of child labourers with experts in the NGO sector and government policy makers lacking detailed knowledge of the field.

Exploring the impact of childhood maltreatment and BPD on impulsivity in crimes of passion

Background

Crimes of passion, characterized as unpremeditated impulsive aggression, have garnered increasing attention in recent years. Impulsivity, a major factor in crimes of passion, is also a common feature of various health conditions, including Borderline Personality Disorder (BPD). Childhood maltreatment is considered a significant precursor to BPD and is closely related to impulsivity. Although prior research has affirmed the relationship between impulsivity, childhood maltreatment, BPD, and criminal behavior, few studies have examined these variables' interconnections within the context of crimes of passion. This study seeks to explore the relationship between childhood maltreatment, BPD, and impulsivity in crimes of passion, assessing the former's impact on the latter.

Method

Our research examined 133 crimes of passion offenders and 149 other offenders from the Shenzhen male prison in China. All 282 participants completed The Abbreviated Version of The Barratt Impulsiveness Scale (ABIS), The UPPS Impulsivity Scale (Urgency, Premeditation, Perseverance, Sensation Seeking), The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), and The Childhood Trauma Questionnaire (CTQ).

Results

Our findings indicated that (1) crimes of passion offenders scored significantly higher in emotional neglect, physical neglect, and overall childhood maltreatment than did other offenders, and childhood maltreatment scores were notably higher in the high BPD trait group. (2) Crimes of passion offenders demonstrated significantly elevated impulsivity in attention and nonplanning scales compared to other offenders. Impulsivity scores across all scales were also significantly higher in the high BPD trait group. (3) Emotional neglect was found to significantly influence the urgency scale in crimes of passion offenders. An interaction effect was noted between physical abuse and high BPD traits, leading to increased impulsivity in crimes of passion offenders.

Conclusion

This study underscores the predictive roles of childhood maltreatment and BPD in determining impulsivity within the context of crimes of passion.

Preliminary Reporting Patterns of Suicide Ideation and Attempt Among Native American Adolescents in Two Samples

OBJECTIVE

Native American adolescents are disproportionately burdened by suicidality. Here, we examine patterns of reporting of suicide ideation and suicide attempt among Native American youth compared to those from other ethnoracial backgrounds, as this data is important for grounding commonly subscribed to frameworks of suicide risk (e.g., ideation-to-action).

METHOD

Data are from the Youth Risk Behavior Surveillance Survey (N = 54,243; grades 9-12; 51.0% female) and Minnesota Student Survey (N = 335,151; grades 8, 9, 11; 50.7% female). Comparing Native American youth to peers from other ethnoracial backgrounds, we examined two suicide reporting patterns: 1) odds of reporting suicide attempt among those who reported ideation and 2) odds of reporting suicide ideation among those who reported an attempt.

RESULTS

Across both samples, when reporting suicide ideation, youth from other ethnoracial backgrounds were 20-55% less likely than Native American youth to also report attempt. While few consistent differences were observed between Native American youth and those from other racial minority backgrounds in patterns of co-reporting suicide ideation and attempt across samples, White youth were between 37% and 63% less likely than Native American youth to report a suicide attempt without also reporting ideation.

CONCLUSIONS

The increased odds of engaging in a suicide attempt with or without reporting ideation question the generalizability of widely held frameworks of suicide risk to Native American youth and have important implications for suicide risk monitoring. Future research is needed to illuminate how these behaviors unfold over time and the potential mechanisms of risk for engaging in suicide attempts in this disproportionately burdened group.Abbreviations: YRBSS: Youth Risk Behavior Surveillance Survey; MSS: Minnesota Student Survey.

Childhood attachment security mediates the effect of childhood maltreatment chronicity on emotion regulation patterns in emerging adulthood

This study uses a 2-wave, longitudinal design to evaluate mother-child attachment security (child-reported) and emotion regulation capacities (wave 1, age 10-12) as mediators linking childhood maltreatment chronicity and emotion regulation (ER) patterns in emerging adulthood (wave 2; N = 399; 48.1% male; 77.2% Black/African-American, 11.3% White, 7.8% Hispanic, 3.8% other race). Children from families eligible for public assistance with and without maltreatment exposure participated in a summer research camp (wave 1) and were recontacted in emerging adulthood (wave 2). SEM results showed that greater maltreatment chronicity predicted lower childhood attachment security, which in turn predicted membership in ER profiles marked by emotion dysregulation and limited access to ER strategies. Greater attachment security predicted membership in adaptive ER profiles in emerging adulthood. Results suggest that insecure attachment is one process by which childhood maltreatment disrupts adaptive ER across development, whereas greater attachment security in childhood can promote multiple forms of adaptive emotion regulation.

The effects of childhood maltreatment on adolescent non-suicidal self-injury behavior: mediating role of impulsivity

Background

Non-suicidal self-injury (NSSI) severely challenges mental health in adolescents. Childhood maltreatment experience acts as high-risk factor for adolescents to engage in NSSI behaviors. On the other hand, impulsivity or loss of control sets the threshold for NSSI execution. Here we examined the effects of childhood maltreatment on adolescent NSSI-related clinical outcomes and the potential role of impulsivity.

Methods

We assessed the clinical data of 160 hospitalized NSSI adolescents and recruited 64 age-matched healthy subjects as a control group. The clinical symptoms of NSSI are expressed by the NSSI frequency, depression, and anxiety measured by the Ottawa Self-Injury Inventory, the Beck Depression Inventory, and the Beck Anxiety Inventory. Childhood maltreatment and impulsivity were assessed with Childhood Trauma Questionnaire and Barratt Impulsiveness Scale.

Results

The results showed that when compared to HC group, NSSI group is more likely to experience childhood maltreatment. Notably, NSSI group with Childhood maltreatment accompanies higher trait impulsivity and exacerbated clinical outcomes, such as NSSI frequency, depression and anxiety symptoms. Mediation analyses indicated that the association between childhood maltreatment and NSSI-related clinical outcomes was partially explained by impulsivity.

Conclusion

We found that NSSI adolescents have a higher proportion of childhood maltreatment. Impulsivity plays a mediating role between childhood maltreatment and NSSI behaviors.

Patterns of childhood maltreatment predict emotion processing and regulation in emerging adulthood

Childhood maltreatment is a potent interpersonal trauma associated with dysregulation of emotional processes relevant to the development of psychopathology. The current study identified prospective links between patterns of maltreatment exposures and dimensions of emotion regulation in emerging adulthood. Participants included 427 individuals (48% Male; 75.9% Black, 10.8% White, 7.5% Hispanic, 6% Other) assessed at two waves. At Wave 1, children (10-12 years) from families eligible for public assistance with and without involvement with Child Protective Services took part in a research summer camp. Patterns of child maltreatment subtype and chronicity (based on coded CPS record data) were used to predict Wave 2 (age 18-24 years) profiles of emotion regulation based on self-report, and affective processing assessed via the Affective Go/No-Go task. Results identified associations between task-based affective processing and self-reported emotion regulation profiles. Further, chronic, multi-subtype childhood maltreatment exposure predicted difficulties with aggregated emotion dysregulation. Exposure to neglect with and without other maltreatment subtypes predicted lower sensitivity to affective words. Nuanced results distinguish multiple patterns of emotion regulation in a sample of emerging adults with high exposure to trauma and socioeconomic stress and suggest that maltreatment disrupts emotional development, resulting in difficulties identifying emotions and coping with emotional distress.

Do Coping Motives and Perceived Impaired Control Mediate the Indirect Links from Childhood Trauma Facets to Alcohol-Related Problems?

INTRODUCTION

The Self-Medication Hypothesis suggests that individuals drink to alleviate undesirable affective states. Behavioral Economics Theory states that individuals deprived of resources (i.e., physically neglected) consume more reinforcing substances when they are available than others. Childhood trauma may indirectly increase impaired control over alcohol (IC; drinking beyond one's own intentions) and thereby increase alcohol use and problems through the employment of coping-motives.

METHOD

A structural equation model that included sex as a covariate examined mediated paths with 612 university students.

RESULTS

Men were less likely to be emotionally abused and were more likely to use greater amounts of alcohol than women did. Physical neglect was directly linked to both more IC and alcohol use. Emotional and sexual abuse were directly linked to more coping motives. Both emotional and sexual abuse were indirectly linked to more alcohol use and its related problems through increased coping motives and IC.

CONCLUSIONS

Consistent with Behavioral Economics Theory, there was a direct link between physical neglect and IC. We also found partial support for the Self-Medication Hypothesis regarding the emotional and sexual abuse trauma dimensions; they indirectly contributed to alcohol use and its related problems via the mediating mechanisms of more coping motives and IC. Our findings suggest coping motives could be a therapeutic target for intervention among those sexually or emotionally abused.

Personality functioning and the pathogenic effect of childhood maltreatment in a high-risk sample

BACKGROUND

While the psychopathological sequalae of childhood maltreatment are widely acknowledged, less is known about the underlying pathways by which childhood maltreatment might lead to an increased risk for mental health problems. Recent studies indicated that impaired personality functioning might mediate this relationship. The aim of the present paper was to extend the current literature by investigating the mediating effect of impaired personality functioning between different types of childhood maltreatment and self-reported mental health problems in a high-risk sample.

METHODS

Overall, 173 young adults (mean age = of 26.61 years; SD = 3.27) with a history of residential child welfare and juvenile justice placements in Switzerland were included in the current study. The Childhood Trauma Questionnaire (CTQ-SF), Semi-structured Interview for Personality Functioning DSM-5 (STiP-5.1) and the self-report questionnaires of the Achenbach System of Empirically Based Assessment scales (ASEBA) were used. Mediation analyses were conducted through structural equation modeling.

RESULTS

Overall, 76.3% (N = 132) participants indicated at least one type of childhood maltreatment, with emotional neglect being most commonly reported (60.7%). A total of 30.6% (N = 53) participants self-reported mental health problems. Emotional abuse (r = 0.34; p < .001) and neglect (r = 0.28; p < .001) were found to be most strongly associated with mental health problems. In addition, impaired personality functioning was fond to be a significant mediator for overall childhood maltreatment (β = 0.089; p = 0.008) and emotional neglect (β = 0.077; p = 0.016). Finally, impaired self-functioning was found to be a significant mediator when both self-functioning and interpersonal functioning were included as potential mediators in the relationship between overall childhood maltreatment (β1 = 0.177, p1 = 0.007) and emotional neglect (β1 = 0.173, p1 = 0.003).

CONCLUSION

Emotional neglect may be particularly important in the context of childhood maltreatment, personality functioning, and mental health problems and, therefore, should not be overlooked next to the more "obvious" forms of childhood maltreatment. Combining interventions designed for personality functioning with trauma-informed practices in standard mental health services might counteract the psychopathological outcomes of maltreated children and adolescents.

Childhood maltreatment and impulsivity in offenders: Examining the mediating roles of self-compassion and cognitive reappraisal

BACKGROUND

The higher impulsivity of offenders in prison is a challenge for prison intervention. Childhood maltreatment, one of the factors closely related to the generation and development of impulsivity, is also prevalent in offenders. Therefore, it is critical to investigate the underlying paths that generate impulsivity in offenders who have experienced childhood abuse.

OBJECTIVE

Targeting positive protective factors, this study aimed to probe the mediating roles of self-compassion and cognitive reappraisal in the relationship between childhood maltreatment and impulsivity in offenders.

METHODS

The participants included 2643 offenders, 1534 males and 1109 females. Each participant completed the appropriate questionnaires to measure childhood maltreatment, impulsivity, self-compassion, and cognitive reappraisal. The PROCESS macro was used to perform the mediation analysis and hypothesis testing.

RESULTS

The findings showed that childhood maltreatment indirectly affected offenders' impulsivity through self-compassion and cognitive reappraisal, and the mediating effect of self-compassion was stronger than that of cognitive reappraisal. Further analyses found that sexual abuse indirectly affected impulsivity through self-compassion, and the remaining types of childhood maltreatment were associated with impulsivity in indirect pathways through self-compassion and cognitive reappraisal.

CONCLUSIONS

The results suggest that reinforcing practical training in self-compassion and cognitive reappraisal, especially the former, might facilitate the reduction of impulsive symptoms among offenders with backgrounds of childhood maltreatment.

Childhood emotional abuse and motor impulsiveness among male violent inmates with antisocial personality disorder

This study aimed to explore the relationship among childhood maltreatment, impulsiveness and antisocial personality through a questionnaire survey of violent male inmates. We found that the scores of inmates with Antisocial Personality Disorder (ASPD) in Childhood Trauma Questionnaire-28 item Short Form (CTQ-SF) and Barratt Impulsive Scale-11 (BIS-11) were higher than those in the Non-Antisocial personality group, and there was a significant correlation between the scores of CTQ-SF and BIS-11. We found that the interaction between impulsivity and childhood abuse predicts ASPD levels. Moreover, motor and non-planning impulsiveness played important roles in the observed differences in antisocial personality scores among the inmates who had experienced childhood maltreatment; motor impulsiveness was mainly related to emotional abuse, physical abuse, and sexual abuse, while non-planning impulsiveness was mainly related to emotional neglect and physical neglect. These findings suggest that identifying and providing timely intervention for inmates with high impulsiveness who experienced maltreatment in childhood may also contribute to the prevention of violent behavior and to better prison management.

It Is Not What Happens to You But How You React to It That Matters: PTSD as a Moderator of the Association Between Trauma and Impulsive Behaviors

ABSTRACT

We examined the moderating role of posttraumatic stress disorder (PTSD) in the association between trauma and impulsive behaviors. Adult women ( N = 97) with a history of childhood sexual abuse (CSA; n = 26), rape in adulthood ( n = 21), both CSA and adult rape ( n = 25), or no history of sexual trauma ( n = 25) completed self-report questionnaires. PTSD symptoms were positively associated with self-harm and with stealing and accident proneness, but not with sexual impulsivity. Trauma group had no independent associations with impulsive behaviors. PTSD reexperiencing symptoms interacted with trauma group such that reexperiencing symptoms were positively associated with self-harm for the two trauma groups that included CSA but not for the control and adult rape-only groups. Overall, results indicate that PTSD symptoms-more so than the occurrence of trauma itself-associate with impulsive behavior. Results highlight the importance of assessing posttraumatic symptomatology, and not just trauma occurrence, when aiming to prevent or treat impulsive behaviors.

Impulsivity as a mediator between childhood maltreatment and suicidal behavior: A systematic review and meta-analysis

Childhood maltreatment is a known risk factor for the development of suicidal behavior. Possible mediators of the association between childhood maltreatment and suicide have been analyzed. Some studies have considered impulsivity as one of these mediators, but there are no previous reviews on this topic. We, therefore, present a systematic review and mediation meta-analysis of the literature summarizing the evidence on impulsivity as a mediator of the relationship between childhood maltreatment and lifetime suicidal behavior. This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The review was registered in the PROSPERO database. We searched PubMed, PsycINFO, WebOfScience, and EMBASE databases up to February 2021 to identify studies exploring the association between childhood maltreatment and suicide through impulsivity. Fourteen articles met the selection criteria and were included in the review. Seven articles could be included in the mediation meta-analysis. Impulsivity was a significant mediator of the relationship between childhood maltreatment and suicidal behavior in ten of the fourteen included studies. This result was confirmed using mediation meta-analysis (β = .06, 95% CI 0.03-0.10). Studies suggest that exposure to traumatic situations in childhood affects the proper neurobiological, cognitive, and affective development of individuals. This may increase impulsivity, which in turn would be related to an increased risk of suicide. The effects of childhood maltreatment and impulsivity may be both therapeutic targets of interest to reduce suicide rates.

In young women, a link between childhood abuse and subliminal processing of aversive cues is moderated by impulsivity

BACKGROUND

Childhood maltreatment is a serious public health concern. The association between child maltreatment, adverse behaviors, mental health outcomes, and alterations to brain function and structure have begun to be characterized. Less is known about the specific associations of maltreatment subtypes with cue-response to evocative cues and the moderating effects of confounding mental health/behavioral variables.

METHODS

Fifty-four emerging adult women (aged 18-24) completed assessments for behaviors, mental health, and childhood maltreatment. They participated in a fMRI task featuring passive viewing of evocative (33 ms) cues presented by "backward masking" to prevent conscious processing. Correlations of abuse/neglect scores, behavioral/mental health factors, and brain function were assessed. Follow-up analyses investigated the moderating effects of behavioral/mental health factors on maltreatment and brain relationships.

RESULTS

Greater frequency of childhood abuse and neglect were correlated with higher scores of impulsivity, depressive symptoms, and anxious attachment. Childhood abuse was positively associated with increased medial orbitofrontal cortical (mOFC) response to aversive (vs. neutral) cues. Among the behavioral/mental health variables, only impulsivity appeared to have a moderating effect on the relationship between childhood abuse and brain response to aversive cues.

CONCLUSIONS

The link between childhood abuse and a heightened mOFC response to "unseen" aversive stimuli, moderated by impulsivity, adds to the growing literature on the impact of prior adversity on brain function. These findings offer further understanding for the way in which childhood maltreatment affects the brain processing of negative stimuli, helping to explain the well-documented link between childhood maltreatment and a variety of adverse outcomes in adulthood.

Enduring effect of abuse: Childhood maltreatment links to altered theory of mind network among adults

Childhood maltreatment (CM) confers a great risk of maladaptive development outcomes later in life, however, the neurobiological mechanism underlying this vulnerability is still unclear. The present study aimed to investigate the long-term consequences of CM on neural connectivity while controlling for psychiatric conditions, medication, and, substance abuse. A sample including adults with (n = 40) and without CM (n = 50) completed Childhood Trauma Questionnaire (CTQ), personality questionnaires, and resting-state functional magnetic resonance imaging scan were recruited for the current study. The whole-brain functional connectivity (FC) was evaluated using an unbiased, data-driven, multivariate pattern analysis method. Relative to controls, adults with CM suffered a higher level of temperament and impulsivity and showed decreased FC between the insula and superior temporal gyrus (STG) and between inferior parietal lobule (IPL) and middle frontal gyrus, STG, and dorsal anterior cingulate cortex (dACC), while increased FC between IPL and cuneus and superior frontal gyrus (SFG) regions. The FCs of IPL with dACC and SFG were correlated with the anxious and cyclothymic temperament and attentional impulsivity. Moreover, these FCs partially mediated the relationship between CM and attentional impulsivity. Our results suggest that CM has a significant effect on the modulation of FC within theory of mind (ToM) network even decades later in adulthood, and inform a new framework to account for how CM results in the development of impulsivity. The novel findings reveal the neurobiological consequences of CM and provide new clues to the prevention and intervention strategy to reduce the risk of the development of psychopathology.

ANKK1 and TH gene variants in combination with paternal maltreatment increase susceptibility to both cognitive and attentive impulsivity

Recent scientific findings suggest that dopamine exerts a central role on impulsivity, as well as that aversive life experiences may promote the high levels of impulsivity that often underlie violent behavior. To deepen our understanding of the complex gene by environment interplay on impulsive behavior, we genotyped six dopaminergic allelic variants (ANKK1-rs1800497, TH-rs6356, DRD4-rs1800955, DRD4-exonIII-VNTR, SLC6A3-VNTR and COMT-rs4680) in 655 US White male inmates convicted for violent crimes, whose impulsivity was assessed by BIS-11 (Barratt Impulsiveness Scale). Furthermore, in a subsample of 216 inmates from the whole group, we also explored the potential interplay between the genotyped dopaminergic variants and parental maltreatment measured by MOPS (Measure of Parental Style) in promoting impulsivity. We found a significant interaction among paternal MOPS scores, ANKK1-rs1800497-T allele and TH-rs6356-A allele, which increased the variance of BIS-11 cognitive/attentive scores explained by paternal maltreatment from 1.8 up to 20.5%. No direct association between any of the individual genetic variants and impulsivity was observed. Our data suggest that paternal maltreatment increases the risk of attentive/cognitive impulsivity and that this risk is higher in carriers of specific dopaminergic alleles that potentiate the dopaminergic neurotransmission. These findings add further evidence to the mutual role that genetics and early environmental factors exert in modulating human behavior and highlight the importance of childhood care interventions.

Adolescent Sexual Behavior Patterns, Mental Health, and Early Life Adversities in a British Birth Cohort

This study tested adolescent sexual behavior patterns at age 14, their association with mental health at age 17 (psychological well-being, substance use, and self-harm attempts), and the influence of early life adversities upon this association. A British birth cohort (5,593 boys and 5,724 girls from the Millennium Cohort Study) was used. Latent class analysis suggested five subgroups of adolescent sexual behaviors: a "no sexual behavior" (50.74%), a "kisser" (39.92%), a "touching under clothes" (4.71%), a "genital touching" (2.64%), and an "all sexual activities" class (1.99%). Adolescents from the "kisser," "touching under clothes," "genital touching," and "all sexual activities" classes reported significantly more substance use and self-harm attempts compared to adolescents from the "no sexual behavior" group. The associations became weaker after controlling for early life adversities (reducing around 4.38% to 37.35% for boys, and 9.29% to 52.56% for girls), and reduced to a smaller degree after further controlling for mental health variables at 14. The associations between sexual behaviors and psychological well-being became non-significant after controlling for early life adversities. Adolescents who have engaged in low-intensity sexual activities at early age may have poorer reported mental health, a pattern that is stronger for girls and early life adversity may partially explain this association.

Patterns of Child Maltreatment and the Development of Conflictual Emerging Adult Romantic Relationships: An Examination of Mechanisms and Gender Moderation

Individuals who experienced child maltreatment are at heightened risk for involvement in conflictual romantic relationships. The aim of this study was to examine the effect of patterns of child maltreatment on the development of maladaptive romantic relationships in emerging adulthood (EA), as well as to determine whether childhood physical aggression and disinhibition mediate this risk. Utilizing a longitudinal sample of emerging adult participants (N = 398 emerging adults; M_age = 19.67 years) who took part in a summer research camp as children (M_age = 11.27 years), we employed a combination of person-centered and variable-centered methods to test study aims. Significant differences in child behavior and developmental pathways emerged not only between those who experienced maltreatment and those who did not, but also among maltreated individuals with different constellations of maltreatment experiences. Specifically, childhood aggression was a robust mechanism underlying the risk associated with chronic/multi-subtype maltreatment, and the risk associated with neglect only, for involvement in dysfunctional EA romantic relationships. Together, these findings highlight the utility of person-centered methods for conceptualizing maltreatment, identify childhood aggression as a pathway of risk, and the underscore the criticality of prevention and early intervention to interrupt the intergenerational transmission of high conflict and aggression within families.

Examining the roles of emotion dysregulation and impulsivity in the relationship between psychological trauma and substance abuse among women with bulimic-spectrum pathology

Individuals with bulimia nervosa report elevated rates of childhood maltreatment, which appears to increase risk for co-occurring substance use problems and negatively impact clinical course. The current study sought to examine the mechanistic pathways by which specific forms of childhood maltreatment may give rise to substance use problems among individuals with bulimic-spectrum pathology. Women with bulimic-spectrum disorders (N = 204) completed measures of childhood trauma, emotion dysregulation, impulsivity, and substance use. Path analysis was used to examine emotion dysregulation and impulsivity as mediators of the relationship between distinct forms of childhood trauma (physical abuse, physical neglect, emotional abuse, emotional neglect, and sexual abuse) and the presence of problematic alcohol/drug use. In the full path model, significant pathways from childhood emotional abuse to emotion dysregulation, childhood emotional neglect to impulsivity, and emotion dysregulation to problematic substance use emerged. Further, emotion dysregulation significantly mediated the relationship between emotional abuse and substance use. Results indicate that emotion dysregulation may be an important mechanism linking a history of childhood emotional maltreatment to later eating and substance use problems, and therefore may be an important treatment target among individuals with co-occurring eating and substance use concerns.Childhood emotional abuse was related to greater emotion dysregulation.Childhood emotional neglect was related to greater impulsivity.Emotion dysregulation was related to greater problematic substance use.Emotional abuse may impact substance use through emotion dysregulation.Creating emotion dysregulation may improve substance and eating disorder symptoms.

Impact of childhood maltreatment and resilience on behavioral and neural patterns of inhibitory control during emotional distraction

Exposure to childhood maltreatment (CM) may disrupt typical development of neural systems underlying impulse control and emotion regulation. Yet resilient outcomes are observed in some individuals exposed to CM. Individual differences in adult functioning may result from variation in inhibitory control in the context of emotional distractions, underpinned by cognitive-affective brain circuits. Thirty-eight healthy adults with a history of substantiated CM and 34 nonmaltreated adults from the same longitudinal sample performed a Go/No-Go task in which task-relevant stimuli (letters) were presented at the center of task-irrelevant, negative, or neutral images, while undergoing functional magnetic resonance imaging. The comparison group, but not the maltreated group, made increased inhibitory control errors in the context of negative, but not neutral, distractor images. In addition, the comparison group had greater right inferior frontal gyrus and bilateral frontal pole activation during inhibitory control blocks with negative compared to neutral background images relative to the CM group. Across the full sample, greater adaptive functioning in everyday contexts was associated with superior inhibitory control and greater right frontal pole activation. Results suggest that resilience following early adversity is associated with enhanced attention and behavioral regulation in the context of task-irrelevant negative emotional stimuli in a laboratory setting.

Preventing E-cigarette use among high-risk adolescents: A trauma-informed prevention approach

Exposure to childhood trauma increases the risk of tobacco use during adolescence. Recent studies have also reported potentially increased vulnerabilities to electronic cigarette (e-cigarette) use among youth with a history of childhood trauma. While empirical evidence supporting the relationship between childhood trauma and adolescent e-cigarette use is emerging, few effective preventive interventions are available to curb e-cigarette use among adolescent victims of childhood trauma. This article reviews current evidence with respect to how childhood trauma could increase risk for nicotine dependence and e-cigarette use in adolescent populations. Furthermore, this paper describes the development, design, and implementation of Rise Above (RA), a randomized, controlled trial of a trauma-informed, e-cigarette preventive intervention. Lessons learned are also discussed, including the challenges of implementing evidence-informed prevention work within communities vulnerable to traumatic events.

Childhood trauma and cardiometabolic risk in severe mental disorders: The mediating role of cognitive control

Background

Cardiometabolic risk is increased in severe mental disorders (SMDs), and there appears to be a relationship between childhood trauma and cardiometabolic risk, possibly related to adverse health behavior. The current study examined the association between childhood trauma and serum lipids and adiposity in SMDs and the potential mediating role of cognitive and personality characteristics.

Methods

Participants with schizophrenia and bipolar spectrum disorders (N = 819) were included, cardiometabolic risk factors (serum lipids, body mass index, and waist circumference) were measured, and history of childhood trauma was assessed by the Childhood Trauma Questionnaire. Cognitive and personality characteristics were available in subsamples, with assessments of cognitive control, impulsiveness, self-esteem, and affective lability. Linear regressions and mediation analyses with Hayes’ PROCESS were performed, adjusting for age, sex, antipsychotic agent propensity of metabolic side-effect, and diagnostic group.

Results

Experience of three or more subtypes of childhood trauma was positively associated with waist circumference in patients with SMDs (p = 0.014). There were no other significant associations between trauma variables and lipid or adiposity measures in the total sample. Cognitive control was a significant mediator between experience of one or two subtypes of childhood trauma and waist circumference.

Conclusions

The results indicate childhood trauma as a predisposing factor for increased waist circumference in individuals with SMDs. Poorer cognitive control, suggestive of adverse health behavior, might be a mediating factor of the association, and the findings indicate the potential importance of increased focus on these factors in prevention and treatment regimens targeting cardiometabolic health.

Childhood attention problems mediate effects of child maltreatment on decision-making performance in emerging adulthood

Decision-making impairments during emerging adulthood confer risk for challenges in social and occupational roles and may increase the odds of developing health problems. Childhood maltreatment is related to maladaptation in cognitive and affective domains (e.g., executive functioning, emotion regulation) implicated in the development of decision-making capacities. This study investigates childhood maltreatment and subsequent childhood attention problems as developmental antecedents of decision making performance in emerging adulthood. At Wave 1, equal numbers of maltreated and non-maltreated children (Mage = 11.28, SD = .97; 51.5% female; mean family income: $22,530/year) were recruited to take part in a research summer camp. The current study includes a subset of participants (n = 379) from Wave 1 who completed the Cambridge Gambling Task (CGT) at Wave 2 (Mage = 19.68, SD = 1.12; 77.3% Black/African American, 11.1% White, 7.7% Hispanic, 4.0% Other race). The CGT measured decision-making performance by assessing betting behavior across trials that differed in probability of winning. ANOVA results showed that emerging adults who experienced maltreatment in childhood placed higher bets and less sensitively adjusted bets across trials varying in level of risk. Longitudinal structural equation modeling results indicated significant relationships between number of maltreatment subtypes and greater childhood inattention, controlling for IQ. In turn, greater attention problems in childhood predicted worse risk adjustment, or ability to modify betting based on the probability of winning on CGT trials. This mediated path shows one process by which maltreatment negatively affects decision making and risk taking processes in emerging adulthood.

The Effects of Childhood Maltreatment on Non-Suicidal Self-Injury in Male Adolescents: The Moderating Roles of the Monoamine Oxidase A (MAOA) Gene and the Catechol-O-Methyltransferase (COMT) Gene

(1) Background: Numerous studies suggest strong associations between childhood maltreatment and nonsuicidal self-injury (NSSI); this is also true for the roles of dopaminergic genes in the etiology of some psychopathologies related to NSSI. Investigating the interactions of environments and genes is important in order to better understand the etiology of NSSI. (2) Methods: Within a sample of 269 Chinese male adolescents (Mage = 14.72, SD = 0.92), childhood maltreatment and NSSI were evaluated, and saliva samples were collected for MAOA T941G and COMT Val158Met polymorphism analyses. (3) Results: The results revealed no primary effects attributable to MAOA T941G and COMT Val158Met polymorphism on NSSI. However, there was a significant three-way interaction between MAOA, COMT, and child abuse (β = −0.34, p < 0.01) in adolescent NSSI. Except for carriers of the T allele of MAOA and the Met allele of COMT, all studied male adolescents displayed higher NSSI scores when exposed to a higher level of child abuse. A similar three-way interaction was not observed in the case of child neglect. (4) Conclusions: The results indicate that the MAOA gene and COMT gene play moderating roles in the association between child abuse and NSSI of male adolescents and suggest the polygenic underpinnings of NSSI.

Non-offending caregiver support in cases of child sexual abuse: An examination of the impact of support on formal disclosures

BACKGROUND

Childhood sexual abuse (CSA) is a highly prevalent issue, impacting a substantial number of children globally (12 %; Stoltenborgh et al., 2011). Past research has found many children who have been sexually abused will delay their disclosure until adulthood, if they disclose at all (McElvaney, 2015; Reitsema & Grietens, 2016). This is often likely because of the adverse impact that reporting abuse can have for the child and their families (especially when committed by an intrafamilial perpetrator). Non-offending caregiver support has evidenced promise in increasing rates of disclosure (Cyr et al., 2014).

OBJECTIVE

It was hypothesized that higher levels of caregiver support would result in shorter delays of disclosure and that less support is given when the abuser is closely related to the child.

PARTICIPANTS AND SETTING

CSA cases (n = 164) were pulled from the RCMP database of reported crimes for the greater Okanagan Area, British Columbia, Canada.

METHODS

Cases were coded for non-offending caregiver behaviors that indicated support and for relation to perpetrator.

RESULTS

Higher levels of non-offending caregiver support were found to lead to shorter delays of disclosure. Non-offending caregivers were significantly less supportive when the abuser was more closely related.

CONCLUSIONS

Caregiver support acted as a protective factor against delays of disclosure. However, this support decreased significantly when the abuser was closely related. The current study provides evidence for the need to support caregivers of children who have been abused with educational programs and resources so they can properly support the child impacted.

Childhood Maltreatment in Bipolar Disorders

In this chapter, we will focus on childhood maltreatment and its role in the vulnerability to BD.We will review how childhood maltreatment and trauma not only predispose to the development of BD but also to a more unstable, pernicious, and severe clinical expression of the disorder. This environmental risk factor is suggested to be part of a multiple hit model of vulnerability, involving not only early stressors (prenatal and postnatal ones) but also interactions with the genetic background of individuals and with other stressors occurring later in life. We will also review how childhood maltreatment and trauma may modify the brain functioning and circuits and alter some biological pathways in BD, hence leading to psychopathology. Finally, we will briefly discuss the implications for clinical practice and treatment.

Maltreatment exposure across childhood and low-grade inflammation: Considerations of exposure type, timing, and sex differences

Links between child maltreatment and low-grade inflammation in adulthood are well documented, but these studies often rely on adults to report retrospectively on experiences of childhood abuse. Furthermore, these findings raise questions about whether exposure to childhood maltreatment needs time to "incubate," only giving rise to nonresolving inflammation in adulthood, or whether heightened inflammation may be observable in childhood, closer in time to the maltreatment exposure. The present study examined this question in a sample of 155 low-income children (ages 8-12), half of whom had been exposed to maltreatment. Trained coders evaluated case reports to classify maltreatment based on timing and exposure type. Blood samples from children assessed C-reactive protein and cytokines, which were used to form a composite of low-grade inflammation. Analyses revealed a marginally significant Maltreatment Exposure × Sex interaction, which suggested that maltreatment exposure was associated with higher inflammation for girls but not boys. Additionally, analyses focused on the accumulation of maltreatment experiences (through multiple forms of maltreatment or across multiple time points) revealed that girls with greater diversity in their maltreatment experiences and those who experienced maltreatment at multiple time points were at greatest risk. Finally, examination of timing of first onset of maltreatment suggested that girls whose exposures occurred before the age of 5 had the highest low-grade inflammation. These findings add new evidence linking maltreatment to inflammation in childhood, which could increase the risk for mental and physical health problems across the lifespan.

Childhood neglect and suicidal behavior: Findings from the National Comorbidity Survey Replication

BACKGROUND

Although child neglect is common, there has been comparatively little research on it or its specific forms and their effects on mental health in adulthood.

OBJECTIVE

This study aimed to examine the association between exposure to different forms of childhood neglect and lifetime suicidal behavior among a nationally representative sample of adults in the U.S. general population.

METHODS

Data were analyzed from 5665 adults that were drawn from the National Comorbidity Survey Replication (NCS-R). Information was obtained on 'care', 'supervisory' and 'medical' neglect in childhood and lifetime suicidal behavior (ideation, plan, attempt). Lifetime psychiatric disorders were based on the World Mental Health - Composite International Diagnostic Interview. Logistic regression analysis was used to examine the associations.

RESULTS

In fully adjusted models, any neglect was associated with significantly increased odds for all forms of suicidal behavior (suicidal ideation, odds ratio [OR]: 1.80, 95 % confidence interval [CI]: 1.42-2.29; plan, OR: 2.27, 95 % CI: 1.78-2.91; attempt, OR: 2.05, 95 % CI: 1.63-2.59, all p < 0.001). In unadjusted analyses all individual forms of neglect were significantly associated with all forms of suicidal behavior. However, when all forms of neglect were included together in the fully adjusted models, care neglect was no longer significantly associated with any form of suicidal behavior.

CONCLUSION

Different forms of childhood neglect are associated with suicidal behavior in adults independent of common mental disorders. Future studies should focus on childhood neglect subtypes in order to better understand the effects of neglect on adult mental health.

Long-term outcomes of childhood sexual abuse: an umbrella review

BACKGROUND

Although many meta-analyses have examined the association between childhood sexual abuse and subsequent outcomes, the scope, validity, and quality of this evidence has not been comprehensively assessed. We aimed to systematically review existing meta-analyses on a wide range of long-term psychiatric, psychosocial, and physical health outcomes of childhood sexual abuse, and evaluate the quality of the literature.

METHODS

In this umbrella review, we searched four databases (PsycINFO, PubMed, Cumulative Index to Nursing and Allied Health Literature, and Global Health) from inception to Dec 31, 2018, to identify meta-analyses of observational studies that examined the association between childhood sexual abuse (before 18 years of age) and long-term consequences (after 18 years). We compared odds ratios (ORs) across different outcomes. We also examined measures of quality, including heterogeneity between studies and evidence for publication bias. This study is registered with PROSPERO, CRD42016049701.

FINDINGS

We identified 19 meta-analyses that included 559 primary studies, covering 28 outcomes in 4 089 547 participants. Childhood sexual abuse was associated with 26 of 28 specific outcomes: specifically, six of eight adult psychiatric diagnoses (ORs ranged from 2·2 [95% CI 1·8-2·8] to 3·3 [2·2-4·8]), all studied negative psychosocial outcomes (ORs ranged from 1·2 [1·1-1·4] to 3·4 [2·3-4·8]), and all physical health conditions (ORs ranged from 1·4 [1·3-1·6] to 1·9 [1·4-2·8]). Strongest psychiatric associations with childhood sexual abuse were reported for conversion disorder (OR 3·3 [95% CI 2·2-4·8]), borderline personality disorder (2·9 [2·5-3·3]), anxiety (2·7 [2·5-2·8]), and depression (2·7 [2·4-3·0]). The systematic reviews for two psychiatric outcomes (post-traumatic stress disorder and schizophrenia) and one psychosocial outcome (substance misuse) met high quality standards. Quality was low for meta-analyses on borderline personality disorder and anxiety, and moderate for conversion disorder. Assuming causality, population attributable risk fractions for outcomes ranged from 1·7% (95% CI 0·7-3·3) for unprotected sexual intercourse to 14·4% (8·8-19·9) for conversion disorder.

INTERPRETATION

Although childhood sexual abuse was associated with a wide range of psychosocial and health outcomes, systematic reviews on only two psychiatric disorders (post-traumatic stress disorder and schizophrenia) and one psychosocial outcome (substance misuse) were of a high quality. Whether services should prioritise interventions that mitigate developing certain psychiatric disorders following childhood abuse requires further review. Higher-quality meta-analyses for specific outcomes and more empirical studies on the developmental pathways from childhood sexual abuse to later outcomes are necessary.
