Searching for a developmental typology of personality and its relations to antisocial behavior: a longitudinal study of a representative sample of men.

The search for an empirically based personality typology has regained the interest of researchers. To date, however, the empirical inquiries were mainly cross-sectional. In this study, an empirically based developmental typology of personality was identified using data from a prospective longitudinal study of a representative sample of men assessed on four occasions from adolescence to midlife. Cluster analyses were performed on measures of Disinhibition, Negative Emotionality, and Extraversion. Four developmental types of personality were identified. The first was characterized by average scores in the three traits in adolescence that decreased rapidly until midlife (38%). The second was similar, but, instead, displayed increases in Extraversion during adulthood (32%). The third type showed high scores in Disinhibition and Negative Emotionality in adolescence that decreased progressively until midlife (23%). The fourth type was characterized by average scores in the three traits during adolescence followed by important increases in Negative Emotionality and decreases in Extraversion during adulthood (7%). These four developmental types of personality seemed to be related to known antisocial behavior trajectories.
