Co-occurrence between marital aggression and parents' child abuse potential: the impact of cumulative stress

Evidence suggests that marital aggression and parent-to-child aggression sometimes occur within the same family, but little is known about why certain families are vulnerable to multiple forms of family aggression. According to family systems theory, negative affect in one family relationship can spread to other family relationships. According to family stress theory, aversive circumstances increase families' vulnerability to disruption and conflict. Based on these theories, the present study tests the hypothesis that cumulative family stresses potentiate the association between marital aggression and parents' child abuse potential. In a series of additive interactional models, husband-to-wife aggression was linked to husbands' and wives' child abuse potential in a context of both high financial stress and high parenting stress but was not linked in a context of low stress. Wife-to-husband aggression was linked to wives', but not husbands', child abuse potential in a context of high stress. These results highlight the potential role of contextual factors in the pervasiveness of aggressive exchanges across multiple family subsystems.     

Family environment and adult attachment as predictors of psychopathology and personality dysfunction among inpatient abuse survivors

The current study explored the role of early family environment and adult attachment style in explaining long-term outcomes among child abuse survivors. Adult patients (N = 80) in a trauma treatment program were assessed for clinical diagnosis and administered a multiscale questionnaire. Hierarchical regression analyses were significant for dissociative identity disorder (DID), substance abuse, anxiety disorder, posttraumatic stress, somatization, and six personality disorder dimensions. Adult attachment styles were significant predictors of most outcome variables. Of particular note was the strong contribution of attachment avoidance to DID. Five family environment scales (Independence, Organization, Control, Conflict, Expressiveness) also contributed to various psychopathological outcomes. Evidence emerged supporting a mediating role for attachment style in the link between family independence and five personality disorder dimensions.     

Adolescent Life Stress and the Cortisol Awakening Response: The Moderating Roles of Attachment and Sex

This longitudinal study investigated how past versus current life stresses relate to adolescents' cortisol awakening response (CAR), an index of hypothalamic–pituitary–adrenal activity. Ninety‐nine adolescents reported previous year life stress at ages 12 and 18. At the second assessment, participants also provided self‐reports of parent and peer attachment and 3 days of cortisol samples. Current stress was associated with heightened CAR for both males and females, whereas past stress was associated with attenuated CAR for males. Attachment to peers buffered the relationship between past stress and attenuated CAR for all adolescents; attachment to parents was a buffer for male adolescents only. Results demonstrate the protective roles of adolescent relationships and highlight sex differences in biopsychosocial development across adolescence.     

Testing differentially methylated regions through functional principal component analysis

DNA methylation is an epigenetic modification that plays an important role in many biological processes and diseases. Several statistical methods have been proposed to test for DNA methylation differences between conditions at individual cytosine sites, followed by a post hoc aggregation procedure to explore regional differences. While there are benefits to analyzing CpGs individually, there are both biological and statistical reasons to test entire genomic regions for differential methylation. Variability in methylation levels measured by Next-Generation Sequencing (NGS) is often observed across CpG sites in a genomic region. Evaluating meaningful changes in regional level methylation profiles between conditions over noisy site-level measurements is often difficult to implement with parametric models. To overcome these limitations, this study develops a nonparametric approach to detect predefined differentially methylated regions (DMR) based on functional principal component analysis (FPCA). The performance of this approach is compared with two alternative methods (GIFT and M3D), using real and simulated data.KEYWORDS: Functional principal component, epigenetics, DNA methylation, next-generation sequencing     

When vocabularies of motive fail: The example of fatal child abuse

Many social theorists emphasize people's capacity for empathic understanding, shared meanings, and forgiveness. They argue that norm violators can achieve social redemption by offering excuses and justifications. The findings from this study show that this is not always true. Evidence from the case records of caretakers accused of killing their children showed that the majority did not try to explain their actions by invoking excuses and justifications. They either pretended they had no idea what happened to the child or constructed a fictional cause of the child's death which made themselves appear innocent. The minority who attempted to explain why they killed a child received little or no forgiveness. These findings show that some norm violations cannot be translated into acceptable vocabularies of motive.I wish to thank Carl J. Couch for his genenous assistance.     

THE "SPONTANEOUS" CESSATION OF MARITAL VIOLENCE: THREE CASE EXAMPLES

Despite general trends for violence in marriage to escalate in frequency and intensity, there are some couples who, through their own efforts, stop being violent. Three such couples are described below, with particular attention given to spouses' reports on the cessation of their violence. Discussion focuses on the implications of these couples' experiences for the treatment of wife battering.     

Trajectories of physical and emotional marital aggression in midlife couples

This study used three-level generalized hierarchical linear modeling to examine trajectories of husbands' and wives' physical and emotional aggression over three assessments and the effects of years since marriage. In this community sample of 118 couples, physical aggression significantly decreased over time (43% per year). Emotional aggression did not significantly change over time, but trajectories significantly differed for husbands (3% increase) versus wives (10% decrease). Longer-duration marriages had lower physical aggression and, for wives only, lower emotional aggression. Aggression trajectories showed considerable variability: 44%-55% of physically aggressive spouses desisted from one assessment to the next; 5%-12% reported start-ups in physical aggression. Discussion addresses the role of gender and type of aggression in aggression trajectories.
