Social and physical aggression trajectories from childhood through late adolescence: Predictors of psychosocial maladjustment at age 18

Evidence-Based Treatment in Practice: PCIT Research on Addressing Individual Differences and Diversity Through the Lens of 20 Years of Service

Parent-Child Interaction Therapy (PCIT) is an intensive parent support program for caregivers and their children who exhibit difficult-to-manage disruptive behaviors. After more than four decades of research supporting its efficacy for reducing children's disruptive behaviors and improving parent-child relationships, PCIT has become one of the most popular and widely disseminated parenting support programs in the world. The evidence for the efficacy of PCIT can be found in many reviews of randomized clinical trials and other rigorous studies. To add to those reviews, our aim was to provide practical guidance on how PCIT can be part of an evidence-based program for families that depends on practitioner expertise, as well as attention to families' diverse needs. To do this, we describe the evolution of PCIT as practiced in a university-community partnership that has continued for over 20 years, alongside a narrative description of selected and recent findings on PCIT and its use in specific client presentations across four themes. These themes include studies of 1) whether the standard manualized form of PCIT is efficacious across a selection of diverse family situations and child diagnoses, 2) the mechanisms of change that explain why some parents and some children might benefit more or less from PCIT, 3) whether treatment content modifications make PCIT more feasible to implement or acceptable to some families, at the same time as achieving the same or better outcomes, and 4) whether PCIT with structural modifications to the delivery, such as online or intensive delivery, yields similar outcomes as standard PCIT. Finally, we discuss how these directions in research have influenced research and practice, and end with a summary of how the growing attention on parent and child emotion regulation and parents' responses to (and coaching of) their children's emotions has become important to PCIT theory and our practice.

Co-development of aggression in elementary school children: The predictive roles of victimization experiences

Aggression among peers is a common and serious problem in school-age children. Physical, relational, and cyber aggression often occur simultaneously but may exhibit heterogeneous developmental patterns. We aimed to identify heterogeneous co-developmental patterns of physical, relational, and cyber peer aggression and to investigate the contributions of victimization experiences to co-developmental trajectories. Participants were 2869 elementary school students (56.2% boys), initially in fourth grade (M_age  = 10.51 years) in China. Longitudinal data on peer aggression were collected from participants semiannually for 2 years. Data on victimization experiences were collected in the initial measurement wave. Parallel process latent curve growth modeling produced four co-developmental trajectories of peer aggression: High Desisting group, Moderate-Increasing group, Moderate-Physical and Relational Aggression group, and Low Stable group. Multivariate logistic regression analyses revealed that childhood emotional abuse, psychological maltreatment by teachers, as well as physical peer victimization, and cyber peer victimization, served as risk factors for severe co-developmental trajectories. The findings highlight the co-development of physical, relational, and cyber aggression. The identification of risk factors for co-developmental trajectories points to the need for continued monitoring and protection from ongoing victimization experiences in the family and school settings to prevent or ameliorate aggressive behavior.

Childhood parenting and adolescent internalizing and externalizing symptoms: Moderation by multilocus hypothalamic-pituitary-adrenal axis-related genetic variation

Genetic variants that regulate hypothalamic-pituitary-adrenal (HPA) axis function have been demonstrated to moderate the association between parenting and mental health. However, extant research has focused primarily on (i) effects of individual genes or (ii) maternal as opposed to paternal parenting. Using a multilocus genetic profile score (MGPS) approach, the current study is the first to examine the moderation effect of multilocus HPA-axis related genetic variants on the association of both maternal and paternal parenting with adolescent internalizing and externalizing symptoms. In a sample of 772 Chinese Han adolescents (Mage = 16.48 ± 1.40 years; 50.1% girls), a theory-driven MGPS was calculated using six polymorphisms within HPA-axis related genes (CRHR1, NR3C1, NR3C2, FKBP5, COMT, and HT1RA). Results showed that the MGPS interacted with both maternal and paternal parenting in the association with adolescent internalizing symptoms, but not externalizing symptoms. Consistent with the differential susceptibility model, adolescents with high versus low MGPS exhibited not only more internalizing symptoms when exposed to low quality of parenting but also less internalizing symptoms when exposed to high quality of parenting. The current findings highlight the potential value of using a multilocus approach to understanding gene-by-environment interaction (G×E) effects underlying mental health. Within such G×E effects, not only maternal but also paternal parenting should be addressed.

Correlations of impulsivity and aggressive behaviours among adolescents in Shanghai, China using bioecological model: cross-sectional data from Global Early Adolescent Study

OBJECTIVE

To examine the correlations between impulsivity and aggressive behaviours among Chinese adolescents.

DESIGN

A school-based cross-sectional study.

SETTING

Three primary middle schools located in less developed communities of Shanghai.

PARTICIPANTS

1524 adolescents aged 11-16 years.

MEASURES

The impulsivity was measured by Barratt Impulsivity Scale, and the aggressive behaviours were determined by self-reports. Data were collected through computer-assisted self-interview using tablets. Multivariate Firth logistic regression model was conducted to examine correlations between total, attentional, motor, and non-planning impulsivity and aggressive behaviours, respectively.

RESULTS

Totally, 7.48% of participants reported aggressive behaviours toward others during the past 6 months. The proportion of aggressors among boys and girls was 10.60% and 4.18%, respectively. Results of the multivariate regression suggested the risk of aggressive behaviours was significantly increased among those with the highest tertile of total impulsivity (adjusted OR (aOR)_boys=3.14, 95% CI: 1.48 to 6.65; aOR_girls=3.74, 95% CI: 1.10 to 12.76) and motor impulsivity (aOR_boys=2.91, 95% CI: 1.46 to 5.82; aOR_girls=3.57, 95% CI: 1.25 to 10.20.), comparing with those with the lowest tertile, for boys and girls, respectively. Besides, younger age, lower social cohesion and being bullied within 6 months were associated with a higher risk of aggressive behaviours among girls. Less family caring and being bullied within 6 months were associated with the risk among boys.

CONCLUSIONS

The present study indicates a positive association between impulsivity and aggressive behaviours, with a more salient correlation between motor impulsivity subtrait and aggressive behaviour among both boys and girls. Furthermore, adolescents' aggressive behaviours were affected by multiple factors from individuals, family, peers and community. Comprehensive intervention strategies such as controlling the aggressor's impulsivity, helping them better channel their anger, creating a better family, school and neighbourhood environment, and providing support and services for victims of violence are needed.

Listening In: How Parent-Child Communication Relates to Social and Physical Aggression

In this study, we investigated the relations between features of parent-child conversations (neutral talk, positive and negative in-dyad and out-dyad talk) and children's social and physical aggression from ages 9-18. Participants were 297 youth (52% girls) of about 9 years old at Time 1 and their parent. Fifty-two percent of this United States sample identified as White, 20% Black, 20% Hispanic, 8% other races/ethnicities. One hundred eighty-seven parents participated in the parent-child observation task. Ninety four percent of parent participants were mothers. Parent-child conversations were observed in the laboratory during preadolescence, and teachers reported child's aggression. Using multinomial logit analyses, we found that coded observations of communication features predicted membership in linear trajectories of social and physical aggression across nine years of adolescence; trajectories were derived via mixture modeling. Parent and child communication characteristics were related to trajectories of aggression that spanned preadolescence and adolescence; however, not all predicted associations were significant. Children's talk about neutral topics predicted being on a lower social aggression trajectory. Positive out-dyad talk from children was related to being on a lower physical aggression trajectory, as was parent in-dyad positive talk. After controlling for other factors, neither parent nor child in- or out-dyad negative talk was associated with social or physical aggression. These findings highlight the importance of positive communication by youth and toward youth in association with long-term social adjustment.

A systematic review of the factors associated with the course of borderline personality disorder symptoms in adolescence

BACKGROUND

Research on personality pathology in adolescence has accelerated during the last decade. Among all of the personality disorders, there is strong support for the validity of borderline personality disorder (BPD) diagnosis in adolescence with comparable stability as seen in adulthood. Researchers have put much effort in the analysis of the developmental pathways and etiology of the disorder and currently are relocating their attention to the identification of the possible risk factors associated with the course of BPD symptoms during adolescence. The risk profile provided in previous systematic reviews did not address the possible development and course of BPD features across time. Having this in mind, the purpose of this systematic review is to identify the factors that are associated with the course of BPD symptoms during adolescence.

METHODS

Electronic databases were systematically searched for prospective longitudinal studies with at least two assessments of BPD as an outcome of the examined risk factors. A total number of 14 articles from the period of almost 40 years were identified as fitting the eligibility criteria.

CONCLUSIONS

Factors associated with the course of BPD symptoms include childhood temperament, comorbid psychopathology, and current interpersonal experiences. The current review adds up to the knowledge base about factors that are associated with the persistence or worsening of BPD symptoms in adolescence, describing the factors congruent to different developmental periods.

Exploring text messaging as a platform for peer socialization of social aggression

This study examined whether adolescents' social aggression is socialized through exposure to peers' socially aggressive text messaging. Using data on the socially aggressive content of text messages that 221 participants (Mage = 15.02 years; 46.7% female) sent to and received from peers, and teacher ratings of participants' in-person social aggression, this study found that exposure to peers' socially aggressive texting about out-dyad peers predicted positive changes in adolescents' text-based and in-person social aggression. Gender differences were examined, and results were mixed. In ninth grade, girls sent more socially aggressive text messages than boys; however, by 10th grade, these differences disappeared. Gender differences in adolescents' in-person social aggression and their exposure to peers' socially aggressive texting were nonsignificant at both time points. There was no evidence of gender differences in the links between exposure to peers' socially aggressive texting and adolescents' socially aggressive texting. However, marginal differences were found in the associations between exposure to peers' socially aggressive texting and adolescents' in-person social aggression. Results suggest that texting provides an additional platform for peer socialization of adolescents' social aggression. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Relations between Parent Psychological Control and Parent and Adolescent Social Aggression

Parent-child interactions and parenting behavior may be related to social aggression among adolescents, and adolescents' social aggression may relate to parents' social aggression. This study investigated (a) whether parent psychological control predicted future adolescent and parent social aggression in their own peer relationships, (b) whether parents' social aggression was related to their use of psychological control within the parent-adolescent relationship (c) whether adolescents' and parents' social aggression was associated with changes in each other's social aggression over time, and (d) change in psychological control. Participants were 174 racially/ethnically diverse parent-adolescent dyads assessed longitudinally for four years. Adolescents were approximately 15-years-old at the first time point. The adolescent sample was 52% girls and 56% identified as White, 22% as Black or African American, 16% as Hispanic, and 5% as mixed race/ ethnicity. Ten percent of the parent participants were fathers. Parents self-reported their psychological control and social aggression, and their adolescents' teachers reported adolescents' social aggression. Hypotheses were tested using longitudinal structural equation modeling and a latent growth curve analysis. The hypothesized effect of parent's psychological control on parent's future aggression with their own peers was supported. Psychological control positively predicted parent aggression from T2 to T3 (β = .28, p < .05) and from T3 to T4 (β = .37, p < .05). Other hypotheses were not supported. The findings suggest that the parent-child relationship may influence the parent's functioning in their own peer relationships. Parents' peer relations seem to have important implications for their own wellbeing and the parent-child relationship.

Positive Peer Association Among Black American Youth and the Roles of Ethnic Identity and Gender

The study examined whether peer association, a subtype of peer influence that involves the indirect modeling of behaviors, can promote positive development among Black American adolescents living in high-risk neighborhoods. Data were collected during a three-year longitudinal study from a sample of 316 Black American adolescents (M = 11.65 years). As positive peer association increased over time, youth experienced an increase in self-esteem, school connectedness, paternal and maternal closeness, and a decrease in supportive beliefs about aggression. Additionally, lower ethnic identity appeared to account for why some youth experienced a sharper increase in maternal and paternal closeness as positive peer association increased. Future interventions should consider harnessing the ability of prosocial peers to foster healthy development.

Developmental Trajectories of Chinese Adolescents' Relational Aggression: Associations With Changes in Social-Psychological Adjustment

This study investigated the development of relational aggression (RA) in a sample of Chinese youth (N = 2,274, 52% boys) from fourth (M_age  = 10.27 years) to ninth grade. Using latent class growth analysis, four trajectories were identified for both peer- and teacher-rated RA: a no aggression trajectory, a low-increasing trajectory, a moderate-decreasing trajectory, and a chronically high trajectory. Chronically high RA showed a chronicity effect on adolescent peer acceptance, rejection, and rule-breaking behaviors. Adolescents showed worse adjustment as RA increased, but they did not necessarily evidence significant improvement in adjustment even if their RA decreased. Findings reveal the maladaptive nature of RA and highlight the importance of considering cultural context in understanding RA.

Feeling unrestricted by rules: Ostracism promotes aggressive responses

The current research consisted of three studies (overall N = 338; 59 men; mean age = 19.98; SD = 1.75), which aimed to examine whether ostracism promotes aggression through enhanced feelings of rule negligence by adopting a multi-method approach. Participants were undergraduate students in a public university in Hong Kong and they only participated in one of the three studies. The results showed that ostracized participants reported higher levels of rule negligence and aggression than non-ostracized participants (Studies 1 and 2). Moreover, enhanced feelings of rule negligence significantly mediated the relation between ostracism and aggression (Studies 1 and 2). In addition, priming ostracized people with the importance of following social rules weakened the effect of ostracism on aggression (Study 3). In sum, these findings highlight the critical influence of rule negligence in understanding when and why ostracism promotes aggression and how to diminish such an effect. Implications were discussed.
