Sexual abuse of children—Unique in its effects on development?

Different types of childhood adversity often cluster and overlap, underlining the importance of studying likely patterns of adversity co-occurrences and their impact on child functioning. Further sex-specific investigations of adversity co-occurrences and their associations with child mental health are warranted.

To investigate if different sex-specific patterns of childhood adversity exist among at risk-children living in Denmark and to explore if divergent constellations of adversity are differentially associated with externalizing and internalizing problems.

Participants (N = 2198) were a sample of children ages 1–17 who have been in contact with the Danish child protection system due to suspected child abuse. The study included existing data collected as a part of child case procedures.

Latent class analysis was used to identify patterns of adversity co-occurrences among girls and boys, respectively. Inter-class differences on age and child mental health were assessed using ANOVAs.

Greater variation and complexity in adversity exposure was found among girls (5 classes) compared to boys (3 classes). The female classes differed on age (p < .001, η2 = 0.06), internalizing (p < .001, η2 = 0.05), and externalizing problems (p = .002, η2 = 0.02). The male classes differed on internalizing (p < .001, η2 = 0.02) and externalizing problems (p < .001, η2 = 0.04). Overall, classes characterized by multiple adversities displayed higher scores of mental health problems compared to less exposed classes.

Exposure to multiple adversities is common among at-risk children. Information on different sex-specific patterns of adversity co-occurrences can guide intervention planning for affected children.

This study investigated synergy of commonly co-occurring pairs of childhood traumas/adversities to determine: 1) if synergistic pairings differ by gender and/or age grouping; and 2) if some traumas/adversities were more synergistically reactive.

A sample of 10,355 clinic-referred youth (1.5–18 years) from the National Child Traumatic Stress Network Core Data Set was divided by gender and categorized into salient age groups (1.5−5 years, 6−12 years, and 13−18 years). Attributable Proportion (AP), a biomedically relevant metric, was calculated to assess additive synergy for behavior problems on the CBCL.

Overall, only four pairs of adversities were synergistic. Three involved sexual abuse with physical abuse, parental loss, and domestic violence. When the sample was analyzed by Gender X Age group, however, a more complicated picture emerges. Twelve of the twenty-one possible pairings (57 %) show additive synergy in one or more categories. The mean AP accounted for approximately 40 % of outcome variance. Males had more synergistic pairings (16) than females (7). The average synergistic effect was higher for males (42 % of variance) than females (36 % of variance). The vast majority of synergy occurs in the 6−12 and 13−18 age groups. Sexual abuse was the most synergistically reactive trauma, pairing most frequently (16) followed by physical abuse (10) or neglect (9).

Sexual abuse was malignantly synergistic, frequently pairing with other adversities, followed by physical abuse, neglect, and domestic violence. The findings underscore that all ACEs are not equal in their contributions to commonly assessed outcomes. The findings also have considerable implications for prevention, intervention, and future research.

There are specific factors, most that are tragically preventable, involved in the premature violent deaths of people in Australia. This chapter discusses homicide participants, either the victim or perpetrator, who have also been sexually victimised as a child (a child is defined as being under the age of 18 years in this chapter) and will only include deaths perpetrated by adults, not other children. This chapter identifies the causal factors that make survivors of child sexual abuse (CSA) vulnerable to being involved in acts of fatal violence and provide commentary on trends and issues. Discussions of homicide will make reference to the most recent Australia National Homicide Monitoring Program (2012–14) data, and information sourced from national coronial data will provide the three case studies.

The purpose of this study was to evaluate whether childhood maltreatment is associated with smoking behaviors and lifetime nicotine dependence and if associations are moderated by sex. We examined these associations among individuals who ever reported being regular smokers.

Using data from the National Longitudinal Study of Adolescent to Adult Health, we examined relationships between retrospectively self-reported child maltreatment (parent/caregiver-perpetrated emotional, physical, sexual abuse, and neglect; and non-parent/caregiver-perpetrated sexual abuse) and self-reported smoking behaviors among individuals with a history of regular smoking. Outcomes were any current smoking in early adulthood (mean age = 28 years), current smoking in adolescent study waves only, adulthood only, and adolescence and adulthood (n = 3581); and lifetime history of nicotine dependence (n = 3594) per the Fagerstrom scale.

Poly-maltreatment (aRR for 2+ vs. 0 exposures = 1.20, 95% CI: 1.08, 1.34) was associated with lifetime nicotine dependence; associations between nicotine dependence and neglect and non-parent/caregiver sexual abuse by force were only present in women. Neglect and non-parent/caregiver sexual abuse by nonphysical threat were associated with continued smoking, and an association between non-parent/caregiver sexual abuse by physical force and continued smoking was also noted in women only. Women who experienced poly-maltreatment were less likely to report current smoking in adolescence but not adulthood.

These data suggest in a nationally representative sample of ever regular smokers, child maltreatment is associated with outcomes that suggest an inability to quit smoking and some associations may vary by sex.

Child maltreatment is a complex and multifaceted construct in need of advanced statistical techniques to improve its measurement. The current study compared the predictive utility of a cumulative index to a factor analytic approach for constructing a measure of maltreatment. Data were from Waves III and IV of the National Longitudinal Study of Adolescent to Adult Health (Wave III: n = 14,800; Wave IV: n = 12,288). As adults, participants retrospectively reported on their childhood experiences of physical abuse, sexual abuse, emotional abuse, physical neglect, supervisory neglect, and social services investigations. Both the cumulative index and a two-factor solution showed evidence of convergent validity, predicting lifetime incidence of homelessness, being paid for sex, and various measures of running away or living apart from biological parents, and prospectively predicting depression, substance use, and criminal behavior. The latent variables, derived from a factor analytic approach, had greater explanatory power for many outcomes compared to the cumulative index, even when controlling for sociodemographic variables. Results suggest that factor analysis is a better methodology than a cumulative index for measuring maltreatment in large datasets when explanatory power for external outcomes is of greatest concern.

Childhood sexual abuse (CSA) is a worldwide problem with severe long-term consequences. A history of CSA can impact the childbearing experience of mothers and fathers; affecting their mental health, parenting skills and compromising infant development. Nonetheless, the perinatal period offers huge opportunity for intervention and hope. This literature review collates evidence for perinatal psychosocial interventions targeting both mothers and fathers who are survivors of CSA. Publications dating from 1970 to June 2016 were searched using Medline, Maternity and Infant Health, PsychINFO, PsychArticles, PubMed and the International Bibliography of the Social Sciences (IBSS). There were no perinatal interventions that considered the needs of survivor fathers. Sixteen publications on 9 psychosocial perinatal interventions for CSA survivors were identified. However, no sub-analyses specific to CSA survivors were reported. Trauma-specific perinatal interventions drew from a range of theoretical models and varied widely in format. Generally interventions were associated with improvements in maternal mental health, parenting competence, infant attachment security and positive public health outcomes. They were safe and feasible to implement, acceptable to parents and therapist, and therapists were able to implement protocols with adequate fidelity. Yet current data is hampered by small sample size, inconsistent reporting of CSA rates and outcome measures, scarcity of observational data and longer-term follow-up. Intervention modifications are proposed for CSA survivors in view of their unique childbearing experiences.
