Relationships between age of onset, antisocial history and general psychopathological traits in Japanese alcoholics.

This study investigated the relationships of age of onset, antisocial history and general psychopathological traits measured by the Minnesota Multiphasic Personality Inventory (MMPI) in Japanese alcoholics (n = 84). A 2 (earlier vs later onset) x 2 (antisocial vs non-antisocial) multivariate analysis of covariance showed that age of onset had a significant correlation with some subscales of the MMPI such as L (lie), Sc (schizophrenia), and Si (social introversion), whereas history of antisocial behavior had no significant correlation with any MMPI clinical subscales. This result indicated that age of onset was a more significant variable than was antisocial history with regard to the current general psychopathological traits on MMPI in Japanese alcoholics.
