Searching for a developmental typology of personality and its relations to antisocial behaviour: a longitudinal study of an adjudicated men sample.
The search for an empirically based personality typology has regained the interest of researchers. To date, however, empirical inquiries have mainly been cross-sectional. In this study, an empirically based developmental typology of personality was identified using data from a prospective longitudinal study of a sample of men adjudicated during their adolescence and assessed on four occasions until 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 linearly until midlife (39%). The second type displayed very high scores in disinhibition and negative emotionality in adolescence that decreased rapidly during early adulthood (24%). The third type was characterized by very high scores in disinhibition and negative emotionality that remained stable until midlife, while extraversion was average during adolescence and then decreased rapidly until midlife (17%). The fourth type was characterized by high scores in disinhibition and negative emotionality in adolescence that was followed by cycles of decreases and increases until midlife (20%). These four developmental types of personality seemed to be related to known antisocial behaviour trajectories.
