Developmental trajectories of anger and sadness dysregulation in childhood differentially predict later borderline symptoms.

Difficulties with emotion regulation are integral to borderline personality disorder (BPD) and its hypothesized developmental pathway. Here, we prospectively assess trajectories of emotion processing across childhood, how BPD symptoms impact these trajectories, and whether developmental changes are transdiagnostic or specific to BPD, as major depressive (MDD) and conduct disorders (CD) are also characterized by emotion regulation difficulties. This study included 187 children enriched for those with early symptoms of depression and disruptive behaviors from a longitudinal study.

Preschool Age Predictors of Adolescent Borderline Personality Symptoms.

Objective: Developmental models of borderline personality disorder (BPD) have highlighted the interplay of psychological variables (ie, impulsivity and emotional reactivity) with social risk factors, including invalidating parenting and childhood trauma. Prospective longitudinal studies have demonstrated the association of BPD with social, familial, and psychological antecedents. However, to date, few of these studies have studied the interaction of multiple risk domains and their potential manifestations in the preschool period.
