Effects of Physical and Emotional Child Abuse and Its Chronicity on Crime Into Adulthood

A meta-analysis of childhood maltreatment in relation to psychopathic traits

Psychopathy is a personality disorder characterized by a mix of traits belonging to four facets: affective (e.g., callous/lack of empathy), interpersonal (e.g., grandiosity), behavioral instability (e.g., impulsivity, poor behavioral controls), and social deviance (e.g., juvenile delinquency, criminal versatility). Several scholars have argued that early childhood maltreatment impacts the development of psychopathy, although views regarding its role in the four facets differ. We conducted a meta-analysis including 47 studies comprising a total of 389 effect sizes and 12,737 participants, to investigate the association between psychopathy and four types of child maltreatment: physical abuse, emotional abuse, neglect, and sexual abuse. We found support for a moderate link between overall psychopathy and childhood physical abuse, emotional abuse, and neglect, as well as overall childhood maltreatment. The link between psychopathy and childhood sexual abuse was small, but still statistically significant. These associations were stronger for the behavioral and antisocial facets than for the affective and interpersonal facets of psychopathy, but nearly all associations were statistically significant. Our findings are consistent with recently developed theories on the role of complex trauma in the development of severe personality disorders. Trauma-focused preventive and therapeutic interventions can provide further tests of the trauma-psychopathy hypothesis.

Measurement of Adverse Childhood Experiences: It Matters

INTRODUCTION

Alternative measurement approaches for adverse childhood experiences (i.e., count score versus individual adverse childhood experiences measured dichotomously versus individual adverse childhood experiences measured ordinally) can alter the association between adverse childhood experiences and adverse outcomes. This could significantly impact the interpretation of adverse childhood experiences research.

METHODS

Data were collected in 2018 (analyzed in 2020) via Amazon's Mechanical Turk and from people incarcerated in 4 correctional facilities (N=1,451). Included adverse childhood experience questions measured the following: physical, emotional, and sexual abuse; physical and emotional neglect; household mental illness, substance use, domestic violence, and incarceration; and exposure to community violence before age 18 years. A total of 19 measured outcomes spanned 4 domains of functioning: general functioning, substance use, psychopathology, and criminal behavior.

RESULTS

Regression models using the count score explained the least amount of variance in outcomes, whereas multivariable regression models assessing adverse childhood experiences on a continuum explained the most variance. In many instances, the explained variance increased by 2-5 times across the predictive models. When comparing regression coefficients for multivariable regression models that measured adverse childhood experiences as binary versus ordinal, there were notable differences in the effect sizes and in which adverse childhood experiences predicted outcomes. Disparities in results were most pronounced among high-risk populations that experience a disproportionate amount of adverse childhood experiences.

CONCLUSIONS

Alternative methods of measuring adverse childhood experiences can influence understanding of their true impact. These findings suggest that the deleterious effects of imprecise measurement methods may be most pronounced in the populations most at risk of adverse childhood experiences. For the sake of prevention, the measurement of adverse childhood experiences must evolve.

Psychological maltreatment: An international challenge to children's safety and well being

BACKGROUND

Child psychological maltreatment (PM), also known as emotional abuse and neglect, mental violence, and emotional maltreatment, is the least recognized and addressed of the four major forms of child maltreatment.

OBJECTIVES

This article provides an 1) the history of PM and its relationship to children's rights, 2) an overview of the current state of knowledge, 3) implications of diversity for the topic of PM, 4) an example of a topic-relevant intervention, and 5) a vision for further progress in addressing this form of child maltreatment.

PARTICIPANTS AND SETTINGS

NA.

METHOD

Literature review, intervention description of fabricated or induced illness, and expert opinion.

RESULTS

PM is directly implicated in seven of the articles of the Convention. PM is common, reliable definitions of PM exist and need to be applied to practice and public health surveillance, harmfulness has been empirically established but is not fully appreciated, and countries vary dramatically in terms of incidence.

CONCLUSIONS

PM is a human rights issue that must be addressed through child protection and promotion of child wellbeing. Adoption of reliable definitions of the different aspects of PM for Child Protective Service practice is a top policy goal. The development of empirically supported curricula on PM for training professionals and parents and culturally sensitive interventions to change social norms on the use of psychologically aggressive disciplinary practices and other forms of PM are critical research needs. Well-validated interventions to support quality parent-child relationships and support families exist and need to be widely adopted. Individual child protective measures should be confined to cases of ongoing serious PM when interventions have failed to reduce harm to the child.

First Postpubertal Same-Sex Sex in Kinsey's General and Prison Male Same-Sex Samples: Comparative Analysis and Testing Common Assumptions in Minor-Adult Contacts

Kinsey's prison male same-sex sample (consisting of prisoners who were gay, bisexual, or had had extensive postpubertal same-sex sex regardless of sexual attractions) was compared with Kinsey's general (i.e., non-prison) same-sex sample (previously analyzed by Rind and Welter, 2016) in terms of reactions to and characteristics of first postpubertal same-sex sex, with a focus on minor-adult contacts. Prison participants had a minor-adult contact as their first postpubertal same-sex sex twice as often as general participants, and their experience involved penetration in three-quarters of cases compared to only half the time for general participants, and it was paid for (i.e., prostitution) three times as often. Despite these differences, reactions to these events by prison and general participants were the same, with combined results of 66% positive reactions (i.e., enjoyed it "much") versus 15% emotionally negative reactions (e.g., shock, disgust, guilt). Results added to those from a series of studies done since 2000 using male same-sex samples in showing that minor-adult same-sex sexual experiences in this population do not conform to the child sexual abuse (CSA) model of trauma and harm. Comparing prison and general participants also showed that the CSA-trauma-crime link often claimed (i.e., where minor-adult sex is said to produce trauma that leads to later criminal behavior) did not hold in the Kinsey same-sex samples, because trauma (the middle element) was mostly missing. This null result for the link alerts that trauma needs to be shown rather than assumed when considering this link. The positive reaction profile obtained was discussed in terms of cultural factors dominant in Kinsey's time.

Brain alterations potentially associated with aggression and terrorism

A large proportion of the persons who join terrorist groups as well as lone-acting terrorists have a history of violent behavior or mental disorder that predated their becoming terrorists. This suggests that brain alterations found to occur in violent perpetrators may also be present in a significant percentage of terrorists. After a short delineation of phylogenetically old neuronal networks that are important for the generation of aggressive behavior in inconspicuous brains, this review summarizes structural and functional brain-imaging studies in violent offenders published over the last 10 years. Depending on the subtype of violence (impulsive or instrumental), deviations in structure or function were mainly found in the prefrontal, orbitofrontal, and insular cortex, as well as in temporolimbic structures (e.g., the amygdala, hippocampus, and parahippocampus). These brain areas are essentially responsible for the control of the archaic neuronal generators of aggression located in the hypothalamus and limbic system. This regional distribution of brain alterations also shows a remarkable overlap with those brain regions that are crucial for such prosocial traits as empathy and compassion. Feelings of superiority, dominance, and satisfaction gained by performing violent and terroristic attacks suggest that a hedonistic component via an activation of brain reward systems plays an additional role. In our current debate about the causes of terrorism, aspects of brain dysfunction should receive more attention.

Longitudinal Effects of Early Childhood Maltreatment on Co-Occurring Substance Misuse and Mental Health Problems in Adulthood: The Role of Adolescent Alcohol Use and Depression

OBJECTIVE

This study tested a developmental model in which subtypes of childhood maltreatment were hypothesized to have direct and indirect effects on co-occurring depression, anxiety, and substance misuse in adulthood. Indirect effects involved adolescent alcohol use and depression, which were included as mediators in the tested models.

METHOD

This prospective longitudinal study (N = 332; 52.4% male) followed the participants from childhood (18 months to 6 years of age) to adulthood (31-41 years old, M = 36.21). Maltreatment subtypes included parent-reported physical and emotional abuse and child-reported sexual abuse. Adult outcomes included measures of substance misuse and mental health (i.e., depression and anxiety). Latent class analysis and structural equation models were used to identify classes of substance misuse and mental health co-occurrence and to test mediating effects of adolescent alcohol use and depression.

RESULTS

Three classes were identified: (a) low risk of substance misuse and low mental health symptoms, (b) moderate substance misuse risk and mild depression and anxiety, and (c) moderate substance misuse risk and moderate to high depression and anxiety. Structural models showed that effects of childhood sexual abuse were fully mediated by adolescent alcohol use and depression. Physical abuse increased adolescent depression but did not have direct or indirect effects on adult outcome classes. Emotional abuse had a direct effect on the adult classes.

CONCLUSIONS

Children exposed to severe emotional abuse are at higher risk for comorbid substance misuse, depression, and anxiety into their mid-30s, after taking into account evidence of alcohol use and depression during adolescence. Sexual and physical abuse have more proximal effects on adolescent alcohol use and depression, which then influence the risk of adult problems.
