Personality factors in drug addiction.

In spite of the fact that past research has not found a unitary concept of an "alcoholic personality," personality factors have been found to be important in the development of alcohol abuse disorders. Personality characteristics measured by the MMPI, particularly the Pd scale and the MAC scale, have been shown to be related to the development of alcohol abuse disorders. Research is currently under way to explore the ability of the revised version of the MMPI to detect and describe problems of alcohol abuse.
