Two hundred persons arrested for driving under the influence (DUI), 30 social drinkers, 30 depressed patients, 30 incarcerated criminals, and 30 alcoholics completed the Hogan Personality Inventory (HPI) and Court Reporting Network (CRN) interview. A cluster analysis of HPI scores for the DUI group revealed 5 personality types: Impulsive-Extravert, Normal, Neurotic-Introvert, Neurotic-Hostile, and Unassertive-Conformist. The types differed predictably on demographic variables, drinking behavior, and driving records as assessed by the CRN. The Impulsive-Extravert and Normal types had HPI profiles similar to social drinkers. The Neurotic-Introvert type most resembled depressed patients, and the Neurotic-Hostile type most resembled incarcerated criminals. Results clarify previous findings on DUI personality types and establish a basis for tailoring therapeutic treatments to different types of DUI offenders.
