Evolutionary perspective on indirect victimization in adolescence: the role of attractiveness, dating and sexual behavior

We studied indirect victimization from an evolutionary perspective by examining links between this type of victimization and several indicators of attractiveness (past sexual behavior, dating frequency and physical appearance). Two thousand three hundred and nineteen (56% female) students (ages 13-18) from a region of southern Ontario, Canada, completed self-report measures of indirect victimization, physical appearance, dating frequency, recent sexual behavior (number of partners in previous month) and past sexual behavior (number of lifetime partners minus number of partners in previous month) as well as indexes of depression, aggression and attachment security, which were used to control for psychosocial maladjustment. Consistent with an evolutionary framework, physical appearance interacted significantly with gender, wherein attractive females were at greater risk for indirect victimization, whereas for males physical attractiveness was a protective factor, reducing risk of victimization. Physical appearance also interacted with grade, being inversely related to indirect victimization for younger adolescents and having a nonsignificant association with victimization for older youth. Finally, recent sexual behavior was associated with increased risk of indirect victimization for older adolescents only, which we discussed with regard to peer perceptions of promiscuity and short-term mating strategies. These findings have important implications for the development of interventions designed to reduce peer victimization, in that victims of indirect aggression may represent a rather broad, heterogeneous group, including attractive individuals with no obvious signs of maladjustment.

Peer relationships and internalizing problems in adolescents: mediating role of self‐esteem

This study examined whether self‐esteem mediated the association between peer relationships and internalizing problems (i.e., depression and social anxiety). A total of 7290 (3756 girls) adolescents (ages 13–18 years) completed self‐report measures of peer relationships, including direct and indirect victimization, social isolation, friendship attachment (alienation and trust) and friendship quality (conflict and support), as well as self‐esteem, social anxiety and depression. Regression analyses indicated that self‐esteem partially mediated the relations between social isolation, friendship attachment (alienation) and both depression and social anxiety, whereas friendship attachment (trust) was a partial mediator for depression only. Overall, linkages between peer relationships and depression were more strongly mediated by self‐esteem than those between peer relationships and social anxiety. Theoretical and applied implications of these findings are discussed.

Adolescent Bullying, Dating, and Mating

Traditionally believed to be the result of maladaptive development, bullying perpetration is increasingly being viewed as a potentially adaptive behavior. We were interested in determining whether adolescents who bully others enjoy a key evolutionary benefit: increased dating and mating (sexual) opportunities. This hypothesis was tested in two independent samples consisting of 334 adolescents and 144 university students. The data partly supported our prediction that bullying, but not victimization, would predict dating behavior. The data for sexual behavior more clearly supported our hypothesis that bullying behavior predicts an increase in sexual opportunities even when accounting for age, sex, and self-reports of attractiveness, likeability, and peer victimization. These results are generally congruent with the hypothesis that bullying perpetration is, at least in part, an evolutionary adaptive behavior.

Multiple Pathways to Bullying: Tailoring Educational Practices to Variations in Students’ Temperament and Brain Function

In this chapter we examine the characteristics of children with emotionally dysregulated or callous-unempathic temperaments, making reference to underlying neural models, with a view to illustrating the potential benefits of tailoring classroom management strategies to address different kinds of bullying. Drawing upon research examining parenting children with different temperaments, we suggest ways in which teachers may enhance the self-regulation abilities of emotionally dysregulated children who are prone to reactive aggression, including the use of reasoning and explanation in disciplinary situations, facilitating autonomous decision making and conflict resolution, teaching self-control and relaxation techniques, and modeling effective emotion regulation. Similarly, we use this research as a basis for advocating ways for teachers to prevent children with callous-unempathic temperaments from bullying in a proactive, premediated manner, emphasizing the cultivation of a positive teacher–student relationship and the development problem-solving skills in lieu of appeals to empathy and remorse.

Relations Between Adolescent Ratings of Rothbart's Temperament Questionnaire and the HEXACO Personality Inventory

Conventionally, individual differences have been assessed using temperament measures for infants and children, and personality measures for adults. We chose to explore both temperament and personality to see whether a convergence exists specifically during adolescence. A sample of 225 adolescents completed Rothbarts Early Adolescent Temperament Questionnaire–Revised (EATQ–R), a 4-factor temperament scale, and the HEXACO Personality Inventory–Revised (HEXACO PI–R), a 6-factor personality scale. As hypothesized, we found significant relations between the 2 measures. However, there were some important differences between the 2 measures regarding Honesty–Humility, Openness, and Frustration that highlight the unique contributions of both instruments to understanding and measuring adolescent individual differences. As there is a relatively scant history of measuring temperament or personality in adolescence, it is sometimes difficult for researchers to decide which instrument is most appropriate. The results reported here suggest that either the EATQ–R or the HEXACO PI–R could be appropriate, depending on the specific research questions being asked.

Physical and relational bullying and victimization: Differential relations with adolescent dating and sexual behavior

Taking an evolutionary psychological perspective, we investigated whether involvement in bullying as a perpetrator or victim was more likely if adolescents reported having more dating and sexual partners than their peers, an indication of greater engagement in competition for mates. A total of 334 adolescents (173 boys, 160 girls) between the ages of 12 and 16 years (M = 13.6, SD = 1.3), recruited from community youth organizations, completed self-report measures of physical and relational bullying and victimization, as well as dating and sexual behavior. As predicted, pure physical bullying was positively associated with the number of dating and sexual partners, primarily for adolescent boys. Adolescent girls with more dating partners had greater odds of being relational bully-victims, in line with predictions. Finally, adolescent girls with more sexual partners were at greater risk of being physically victimized by peers, and greater involvement with dating and sexual partners was associated with higher odds of being a physical bully-victim. Results are discussed with respect to evolutionary theory and research in which adolescent boys may display strength and athleticism through physical bullying to facilitate intersexual selection, whereas relational bullying may be employed as a strategy to engage in intrasexual competition with rivals for mates.
