There is growing evidence that manifestations of personality pathology are traceable in early years of life. Nevertheless, the existing diagnostic nomenclature contains little recognition of childhood antecedents of adult personality disorders (PD). The current paper suggests that these childhood antecedents are more readily recognized to the extent that the personality disorders are themselves understood as configurations of extreme Five-Factor Model personality traits. From this dimensional perspective, we propose the Dimensional Personality Symptom Itempool (DIPSI), an age-specific model for describing child and adolescent trait pathology. We suggest that the DIPSI represents a comprehensive conceptualization of childhood PD antecedents and may contribute to the understanding of the developmental course of personality disorders. Issues and concerns to further elaborate this life-span perspective on personality disorders are discussed.
