Coercive Parent-Adolescent Interactions Predict Substance use and Antisocial Behaviors Through Early Adulthood: A Dynamic Systems Perspective

Impact of an 8-Week, Intensive Summer Treatment Program on Improving Coercive Caregiver-Child Interactions Among Children With and Without Callous Unemotional Traits

The coercive process is the primary explanatory mechanism implicated in the maintenance of disruptive behavior disorders (DBDs), and understanding the coercive cycle may be especially important for caregivers with children with elevated callous-unemotional (CU) traits. The purpose of the current pilot study is twofold. First, we assessed whether the Summer Treatment Program (STP), an established intensive behavioral intervention for children with DBDs, reduced coercive caregiver-child interactions using a novel parent-report measure of coercive interactions. We then sought to assess whether the STP improved coercive caregiver-child interactions among children with elevated CU traits (i.e., moderated the effect). Thirty-three caregivers and their children who had been diagnosed with DBDs participated in the STP, which involved the children receiving behavior modification for 9 hours per day and caregivers attending a weekly behavioral parent training group session over the course of 8 weeks. Children (Mage = 8.51 years old, SD = 1.70, range 6-12) were primarily male (78.5%) and Hispanic/Latine (84.8%). A linear multilevel model revealed a statistically significant improvement in caregiver-child coercive interactions from pre- to posttreatment. However, child pretreatment CU traits moderated this effect such that families with children with elevated CU traits did not show improvement in caregiver-child coercive cycles following treatment. Results suggest the benefits of intensive behavioral treatment on the caregiver-child coercive cycle for many families, but the need to modify the intensity or dose of treatments for those with children with DBDs and elevated CU traits.

Serial Cascade Effects of Relative Deprivation and Anger Rumination on the Development of Social Aggression Over 2.5 Years in Emerging Adults

Although the mechanisms of development of aggression have been focused on day by day, the complicated effects of distal and proximal factors on the development of social aggression in emerging adults have not been uncovered. A serial cascade model of aggression was proposed to address this issue. A longitudinal investigation over 2.5 years was conducted to test this model by exploring the serial cascade effects of relative deprivation (a representative of distal factors) and anger rumination (a representative of proximal factors) on the development of social aggression. A total of 1113 Chinese university students (Mage = 18.95 ± 0.96, 63.10% female) from six universities in five areas participated in this study. The results suggest that developmental trajectories and longitudinal changes in anger rumination mediate the relationship between developmental trajectories and longitudinal changes in relative deprivation and social aggression, and developmental trajectories and changes in relative deprivation mediate the longitudinal relationship between anger rumination and social aggression. These findings support the serial cascade effects of distal and proximal factors on the development of aggression and expand upon the general aggression model (GAM).

Introduction to the Special Issue: Novel Insights into the Externalizing Psychopathology Spectrum in Childhood and Adolescence from Intensive Longitudinal Data

Externalizing psychopathology is highly prevalent in children and adolescents. Yet, current understanding of the externalizing psychopathology spectrum is predominantly founded on cross-sectional and conventional longitudinal designs. Compared to these designs, intensive longitudinal data have greater ecological validity and provide insight into within-person fluctuations and short-term developmental dynamics. In this Special Issue, we bring together a selection of 10 innovative and original empirical articles to demonstrate the benefits of intensive longitudinal data for understanding the development of the externalizing psychopathology spectrum during childhood and adolescence, as well as one thoughtful commentary from leaders in the externalizing psychopathology field. In this Introduction to the Special Issue, we describe the articles included in this Special Issue in relation to study designs, timescales, samples, and statistical modeling techniques. We conclude by considering the implications of intensive longitudinal data for informing and enhancing our understanding of externalizing psychopathology with child and adolescent samples, as well as critical future research directions.
