Childhood psychological abuse and relational aggression among adolescents: A moderated chain mediation model

Dimensional model of adolescent personality pathology, reflective functioning, and emotional maltreatment

Introduction

Childhood emotional abuse (CEA) is a recognized risk factor for adolescent mentalizing challenges. However, there's limited understanding about how CEA might influence personality development and elevate the risk of adolescent personality pathology. A deeper grasp of these pathways is crucial, given that adolescence is a pivotal developmental phase for identity integration, personality consolidation, and the emergence of personality disorders. As the emphasis shifts to dimensional perspectives on adolescent personality pathology, the spotlight is increasingly on adolescents' evolving personality organization (PO). Within this framework, personality disorder manifestations stem from inherent vulnerabilities in PO. A comprehensive understanding of how CEA leads to these inherent vulnerabilities in PO can inform enhanced interventions for at-risk adolescents. Nonetheless, our comprehension lacks insight into potential pathways to PO, especially those involving external factors like maltreatment and individual traits like mentalizing. This study sought to bridge these gaps by employing latent factor analysis and structural equation modeling to explore connections between emotional maltreatment, adolescent mentalizing, and PO.

Methods

A community-based cohort of 193 adolescents (aged 12-17) took part in self-report assessments: the Childhood Experience of Care and Abuse Questionnaire (CECA.Q), the Reflective Functioning Questionnaire for Youth (RFQ-Y), and the Inventory for Personality Organization for Adolescents (IPO-A).

Results

The structural equation model revealed a significant direct influence of CEA on both RFQ-Confusion and PO, and a noteworthy direct effect of RFQ-Confusion on PO. Remarkably, the model accounted for 76.9% of the PO variance. CEA exhibited a significant indirect impact on PO through RFQ-Confusion, which was accountable for 52.3% of the CEA effect on PO, signifying a partial mediation by mentalizing.

Discussion

These insights carry substantial clinical implications, especially for devising integrated, trauma-informed strategies for adolescents with personality pathologies. This is particularly relevant for enhancing mentalizing and bolstering personality consolidation among adolescent CEA survivors.

Developmental Pathway from Childhood Abuse to Adolescent Peer Victimization: The Role of Rejection Sensitivity and Aggression

Despite the well-established relationship between early experiences of victimization and later re-victimization, little is known about the exact mechanism of this cycle of victimization. The present study examined whether the route from rejection sensitivity to aggression mediates the associations between different forms of childhood abuse and later peer victimization longitudinally. A total of 3525 adolescents (56.6% male; Mage = 13.21 ± 0.85) participated in this three-wave study, with a 6-month lag and a 9-month lag respectively. The results indicated that the association between childhood emotional abuse and peer victimization were independently mediated by aggression, and sequentially mediated by rejection sensitivity and aggression in both sexes. Sex differences existed regarding the association between childhood physical abuse and aggression, such that only in adolescent boys did physical abuse show significant effect on aggression, resulting in later peer victimization. In general, these findings suggest that maladaptive social-cognitive processes and behavioral patterns are crucial for understanding the mechanism of the vicious cycle of victimization, and sex differences must be considered when examining different types of childhood abuse.
