Verbal and Physical Abuse Toward Mothers: The Role of Family Configuration,Environment, and Coping Strategies

This paper focuses on parental maltreatment, a rarely documented phenomenon. We prospectively examine factors that can increase the risk of abusive behavior toward mothers. The purpose of this study is to examine the relationship between a stressful family situation, parental divorce, and verbal and physical aggression toward mothers. We use a large Canadian sample of adolescents who have been followed since kindergarten. At age 15, we assessed verbal and physical abuse toward mothers, as reported by both mothers and their adolescents. Multinomial logit modeling revealed that parental divorce was associated with a greater risk of physical aggression directed toward mothers by adolescents. Family environment and parental coping strategies partially mediated that relationship. Mothers who divorced, and remained divorced, were at greater risk of being assaulted by their adolescent children. A positive family environment, reflecting a better parent–child relationship, partially diminished this risk. However, support-seeking behavior on the part of mothers increased the risk of abuse, concurrent with tyrannical strategies often mobilized by abusive children.     

Do peer group norms moderate the expression of genetic risk for aggression?

Purpose

Using a genetically informed design based on 192 Monozygotic and Dizygotic twin pairs assessed in kindergarten, this study examined whether the expression of genetic risk for physical aggression or for relational aggression varies depending on the peer group’s injunctive behaviour norms.

Methods

Physical aggression and relational aggression, as well as injunctive peer group norms in regard to these behaviours, were measured via peer nominations in the twins’ kindergarten classes.

Results

Peer groups varied considerably in terms of the level of acceptability of both physical and relational aggression. Bivariate Cholesky modeling revealed a significant gene-environment interaction, indicating that a strong genetic disposition for physical aggression was much more likely to be expressed when peer group injunctive norms were favourable to such behaviour. In contrast, genetic factors essentially played no role in explaining inter-individual differences when peer group norms discouraged physical aggression. Relational aggression was generally less explained by genetic influences and more by environmental influences regardless of peer group norms, but environmental influences became even more important when peer group norms favoured such behaviour.

Conclusions

These findings speak to the importance of the peer group in shaping aggression already in young children by either condoning or penalizing such behaviour.     

Risk Factor Models for Adolescent Verbal and Physical Aggression Toward Fathers

Using a French-Canadian population-based longitudinal data set, we examine the impact of socioeconomic factors (paternal education and family structure); inherent individual factors (child gender and developmental trajectories of physical aggression from early to later childhood, problematic substance use), family environment (concurrent parent-child involvement, parental problematic substance use), and prospective and concurrent parenting process variables (mean parental supervision at puberty, concurrent punishment practices) as predictors of adolescent-directed aggression against fathers (in the last 6 months). A childhood behavioral pattern characterized by physical aggression showed the highest risk of adolescent-directed verbal and physical aggression toward fathers, regardless of sex. In terms of parental practices, verbal (and not corporal) punishment in the last 6 months significantly predicted aggression toward fathers. A childhood life-course of violence is likely to culminate in aggression toward fathers during adolescence. Beyond this risk, it seems that harsh verbal punishment by parents builds up the odds of child-directed aggression against fathers.     

Rough-and-Tumble Play and the Development of Physical Aggression and Emotion Regulation: A Five-Year Follow-Up Study

This is a follow-up to a study demonstrating that rough-and-tumble play was related to physical aggression in the preschool years. Fathers reported on the frequency of father-child rough-and-tumble play interactions, and the degree to which fathers were dominant in the play dyad was observed and coded from play interactions. In this follow-up study, school-aged children’s physically aggressive behaviors and emotion regulation abilities were assessed with questionnaires 5 years later. Higher frequencies of father-child rough-and-tumble play in the preschool years were associated with more physical aggression and worse emotion regulation 5 years later for children whose fathers were less dominant, over and above the effects of physical aggression in the preschool years. Rough-and-tumble play was unrelated to these measures among children whose fathers were more dominant during play. This study shows that early rough-and-tumble play continues to be related to children’s psychosocial adjustment over time, and that the effect remains moderated by the quality of the father-child relationship during play.     

Trajectories of Anxiety During Elementary-school Years and the Prediction of High School Noncompletion

Previous research has provided mixed results regarding the effect of anxiety on academic achievement. Building on this body of research, the present longitudinal study pursued two goals. The first goal was to describe trajectories of anxiety during elementary-school years. The second goal was to determine the predictive value of these trajectories on high school noncompletion after controlling for personal (i.e., gender, classroom behaviors, and academic achievement) and familial (i.e., sociofamilial adversity) characteristics. A community sample of 1,817 children (887 boys, 930 girls) participated in this study. Results showed that anxiety tended to fluctuate from kindergarten to Grade 6 for different groups of children. Furthermore, the result of a logistic regression analysis indicated that group membership for anxiety predicted high school noncompletion by age 20. As a whole, these findings suggest that considering heterogeneous developmental patterns of anxiety during elementary-school years appears quite useful for predicting an important outcome such as high school noncompletion.

Early prevention of life-course personal and property violence: a 19-year follow-up of the Montreal Longitudinal-Experimental Study (MLES)

Objectives

This study assessed the impact of a multi-component prevention program on personal and property violence across three developmental periods (early adolescence, mid-adolescence and late adolescence/early adulthood).

Methods

The preventive intervention targeted disruptive kindergarten boys from low socioeconomic status families when they were 7 through 9 years of age. A randomized control trial was conducted to assess the impact of the preventive intervention relative to a control group.

Results

Two different approaches to data analysis were adopted: an intention-to-treat (ITT) approach and an instrumental variable (IV) approach. Results from the ITT analysis showed that the level of property violence for the intervention group was persistently lower across the three developmental periods compared to the control group. However, the intervention group did not differ from the control group on personal violence throughout adolescence and early adulthood. Results from the IV analysis generally confirmed these findings.

Conclusions

The discussion focuses on the differential effects of the prevention program on personal versus property violence.     

Risky Lifestyle as a Mediator of the Relationship Between Deviant Peer Affiliation and Dating Violence Victimization Among Adolescent Girls

Few studies have explored the possible contribution of the peer group to dating violence victimization. The current study tested the hypothesis that a risky lifestyle would mediate the relationship between deviant peer affiliation and dating violence victimization among adolescent girls. The proposed mediation model was derived from lifestyles and routine activities theories. A sample of 550 girls (mean age = 15) drawn from a larger representative community sample in Quebec, Canada, completed a questionnaire on three forms of dating violence victimization (psychological, physical, and sexual). Results revealed that girls with a higher level of affiliation with deviant peers were more likely to endorse a risky lifestyle and reported higher rates of all forms of dating violence victimization. Further analyses showed that, while deviant peer affiliation is associated with dating violence victimization, this relationship may be explained, at least partially for psychological violence, and completely for physical/sexual violence, by the girls’ own risky lifestyle. Future preventive interventions for adolescent dating violence victimization should target deviant peer groups, as well as adolescent girls who display a risky lifestyle.     

Relative Advantages of Person- and Variable-Based Approaches for Predicting Problem Behaviors from Kindergarten Assessments

Kindergarten teacher ratings of physical aggression, hyperactivity,inattention, anxiety, and prosocial behavior were used to predictself-reported delinquency, peer-rated social withdrawal, and schoolplacement in preadolescence (ages 10 to 12 years) in a large longitudinalsample of boys from low socio-economic neighborhoods. Two analyticstrategies were used: person-oriented and variable-oriented approaches. Inthe person approach, eight clusters, based on the kindergarten behaviors,were used to predict delinquency, social withdrawal, and schoolplacement. In the variable approach, the kindergarten behaviors were used asdimensions in logistic regressions. Family adversity was used as the firstpredictor in both approaches; it significantly predicted all the outcomes inpreadolescence. The results obtained using the two approaches were partly inaccordance. In both sets of results, kindergarten teacher-ratedexternalizing behavior problems were most related to later self-reporteddelinquency, and internalizing problems to peer-rated socialwithdrawal. However, the person approach showed that all patterns ofkindergarten behavior problems increased the risk for placement out of anage-appropriate regular classroom, while only inattention and lack ofprosocial behavior were the significant dimensional predictors of thisnegative outcome according to the variable approach. Also, the personapproach showed that the Multiproblem kindergarten boys had the highestpercentage of comorbidity of preadolescent problems. The ROC curvesindicated that prediction of delinquency, social withdrawal, and schoolplacement were equally accurate using the cluster and variableapproaches. Advantages and limits of both approaches are discussed withreference to their usefulness for clinicians.
