Childhood Precursors of Adult Borderline Personality Disorder Features A Longitudinal StudyCramer, Phebe PhDThe Journal of Nervous and Mental Disease: July 2016 - Volume 204 - Issue 7 - p 494–499 doi: 10.1097/NMD.0000000000000514 Original Articles Buy Abstract Author InformationAuthors Article MetricsMetrics This study identifies childhood personality traits that are precursors of adult Borderline Personality Disorder (BPD) features. In a longitudinal study, childhood personality traits were assessed at age 11 (N = 100) using the California Child Q-set (CCQ: Block and Block, 1980). A number of these Q-items were found to be significantly correlated (p < 0.001) with a prototype-based measure of BPD features at age 23. Factor analysis of these Q-items suggested that they could be characterized by two underlying personality dimensions: Impulsivity and Nonconformity/Aggression. The findings thus provide evidence that childhood personality traits predict adult BPD features. Identifying such childhood precursors provides an opportunity for early intervention.
