Abstract

Child maltreatment is a robust risk factor for suicidal ideation and behaviors during adolescence. Elevations in internalizing and externalizing symptomology have been identified as two distinct developmental pathways linking child maltreatment and adolescent risk for suicide. However, recent research suggests that the co-occurrence of internalizing and externalizing symptomology may form a distinct etiological pathway for adolescent risk behaviors. Using the Longitudinal Studies on Child Abuse and Neglect (LONGSCAN) sample (N = 1,314), the present study employed a person-centered approach to identify patterns of concurrent change in internalizing and externalizing psychopathology over five time points from early childhood to adolescence in relation to previous experiences of child maltreatment and subsequent suicidal ideation and behaviors.

RESULTS indicated four distinct bivariate externalizing and internalizing growth trajectories. Group membership in a heightened comorbid internalizing and externalizing symptom trajectory mediated the association between childhood abuse and adolescent suicidal ideation and suicidal behaviors. These findings suggest that the concurrent development of externalizing and internalizing symptoms in childhood and adolescence may constitute a unique developmental trajectory that confers risk for suicide-related outcomes.
