Borderline personality features as a predictor of forms and functions of aggression during middle childhood: examining the roles of gender and physiological reactivity.

The present longitudinal investigation examined borderline personality features as a predictor of aggression 1 year later. Moderation by physiological reactivity and gender was also explored. One hundred ninety-six children (M = 10.11 years, SD = 0.64) participated in a laboratory stress protocol in which their systolic blood pressure, diastolic blood pressure, and skin conductance reactivity to recounting a relational stressor (e.g., threats to relationships or exclusion) were assessed. Teachers provided reports on subtypes of aggressive behavior (i.e., reactive relational, proactive relational, reactive physical, and proactive physical), and children completed a self-report measure of borderline personality features. Path analyses indicated that borderline personality features predicted increases in reactive relational aggression and proactive relational aggression among girls who evinced heightened physiological reactivity to interpersonal stress. In contrast, borderline personality features predicted decreases in proactive physical aggression in girls. Findings suggest that borderline personality features promote engagement in relationally aggressive behaviors among girls, particularly in the context of emotional dysregulation.

Vulnerability to depression: a moderated mediation model of the roles of child maltreatment, peer victimization, and serotonin transporter linked polymorphic region genetic variation among children from low socioeconomic status backgrounds.

Child maltreatment, peer victimization, and a polymorphism of the serotonin transporter gene (5-HTTLPR) were examined as predictors of depressive symptomatology. Children (M age = 11.26, SD = 1.65), including 156 maltreated and 145 nonmaltreated children from comparable low socioeconomic backgrounds, provided DNA samples and self-reports of relational peer victimization, overt peer victimization, and depressive symptoms. Path analysis showed that relational and overt victimization mediated the association between child maltreatment and depressive symptoms. Bootstrapping procedures were used to test moderated mediation and demonstrated that genotype moderated the indirect effects of relational and overt victimization on child depressive symptoms, such that victimized children with the long/long variation were at an increased risk for depressive symptoms compared to victimized children carrying a short allele. Results highlight the utility of examining process models that incorporate biological and psychological factors contributing to the development of depressive symptomatology and provide direction toward understanding and promoting resilience among high-risk youth from a multiple levels of analysis approach.

A cross-lagged structural equation model of relational aggression, physical aggression, and peer status in a Chinese culture.

This short-term longitudinal study examined the associations among relational aggression, physical aggression, and peer status (i.e., acceptance, rejection, and perceived popularity) across three time points, six months apart, in a Taiwanese sample. Participants were 198 fifth grade students (94 girls and 104 boys; Mean age = 10.35 years) from Taipei, Taiwan. Study variables were assessed using peer nomination procedure. Results from the cross-lagged structural equation models demonstrated that there were longitudinal associations between relational aggression and each of the peer status constructs while only one longitudinal association was found for physical aggression such that physical aggression positively predicted subsequent peer rejection. The longitudinal associations did not vary with gender. Results also showed high stabilities of relational aggression, physical aggression, and the three peer status constructs over 1 year as well as high concurrent association between relational and physical aggression. In addition, relational aggression and physical aggression were concurrently related to less acceptance, more rejection, and less perceived popularity, especially at the outset of the study. Findings of this study demonstrated both similarities and differences in relation to previous literature in primarily Western cultures. This study also highlights the bidirectional and complex nature of the association between aggression and peer status, which appears to depend on the form of aggression and on the particular indicator of peer status under study.

Relations of inattention and hyperactivity/impulsivity to preadolescent peer functioning: the mediating roles of aggressive and prosocial behaviors.

This study examined the structural relations of preadolescents' inattention and hyperactivity/impulsivity, aggressive and prosocial behaviors, and peer functioning. There were 739 fourth (n = 239) and fifth (n = 500) graders (52.23% boys) in Taiwan who participated in this study. Preadolescents' inattention and hyperactivity/impulsivity were assessed using parent reports on the Swanson, Nolan, and Pelham IV Rating Scale. Aggressive behaviors, including physical aggression and relational aggression, and prosocial behaviors were assessed using teacher and peer reports. Peer acceptance and the number of reciprocated friendships were obtained through peer nomination administered 6 months later after initial assessment and were combined to assess children's peer functioning. Results of structural equation modeling demonstrated that inattention was indirectly linked to impaired peer functioning through low levels of prosocial behavior, regardless of gender. In addition, inattention was directly related to less optimal peer functioning only for girls. Hyperactivity/impulsivity was neither directly nor indirectly related to impaired peer functioning in boys, although it was related to more physical and relational aggression. However, for girls, a positive and direct path existed between hyperactivity and peer functioning. Further, hyperactivity in girls was associated with more physical aggression, which in turn led to poorer peer functioning. These findings suggested that the processes related to each core domain of ADHD and peer functioning may be varied, depending on the mediating factors (e.g., aggression or prosocial behavior) and gender.

Preliminary Outcomes from an Integrated Pediatric Mental Health Outpatient Clinic.

An estimated 1 in 5 children in the United States meet criteria for a diagnosable mental disorder, yet fewer than 20% receive mental health services. Unmet need for psychiatric treatment may contribute to patterns of increasing use of the emergency department. This article describes an integrated pediatric evaluation center designed to prevent the need for treatment in emergency settings by increasing access to timely and appropriate care for emergent and critical mental health needs. Preliminary results showed that the center provided rapid access to assessment and treatment services for children and adolescents presenting with a wide range of psychiatric concerns.

Relational benefits of relational aggression: adaptive and maladaptive associations with adolescent friendship quality.

Two longitudinal studies examined associations between relational aggression and friendship quality during adolescence. In Study 1, 62 adolescents in Grades 6 (25.8%), 7 (32.3%), and 8 (41.9%) completed assessments of friendship affiliations, relational and overt aggression, and friendship quality at 2 time points, 1 year apart. Results using actor partner interdependence modeling indicated that high levels of relational aggression predicted increases in self-reported positive friendship quality 1 year later. In Study 2, 56 adolescents in Grades 9 (66.7%) and 10 (33.3%) attended a laboratory session with a friend in which their conversations were videotaped and coded for relationally aggressive talk. Target adolescents completed measures of positive and negative friendship quality during the laboratory session and during a follow-up phone call 6 months later. Analyses revealed that high levels of relationally aggressive talk at Time 1 predicted increases in negative friendship quality 6 months later. In addition, among adolescents involved in a reciprocal best friendship, high levels of observed relationally aggressive talk predicted increases in positive friendship quality over time. Taken together, these studies provide support for the idea that relational aggression may be associated with adaptive as well as maladaptive outcomes within the dyadic context of adolescent friendship.
