Childhood maltreatment, peer victimization, borderline personality feature, suicidal risk in adolescents: Direct and indirect associations among developmental trajectories

Abstract

AbstractIntroductionChildhood maltreatment, peer victimization, and borderline personality traits have all been shown to be linked to suicidal risk. However, there remains a need to illuminate the possible direct and indirect pathways among them from a developmental perspective that could serve as intervention targets. This study thus aimed to investigate the direct and indirect relationships among developmental trajectories of childhood maltreatment, peer victimization, borderline personality feature, and suicidal risk in adolescents.MethodsA total of 1648 Chinese adolescents (48.12% boys; Mage = 13.69; SD = 0.82) in junior middle schools completed self‐report measures on three‐time points across 1 year. Latent growth curve modeling was used to evaluate the direct and indirect relationships among the developmental trajectories of the aforementioned study variables.ResultsThe developmental trajectories of childhood maltreatment, peer victimization, and borderline personality feature were positively and directly related to the developmental trajectory of suicidal risk; and the developmental trajectories of childhood maltreatment, peer victimization were indirectly related to the developmental trajectory of suicidal risk through the mediating effect of the developmental trajectory of borderline personality feature.ConclusionsThe findings elucidated the direct and indirect longitudinal relationships among childhood maltreatment, peer victimization, borderline personality feature, and suicidal risk, highlighting that interventions should target childhood maltreatment, peer victimization, and borderline personality feature to decrease suicidal risk in adolescents with a developmental perspective.
