Tridimensional Personality Questionnaire scores of sons of alcoholic and nonalcoholic fathers

The authors studied 33 men whose fathers had severe alcohol-related problems and 33 subjects with no family history of alcoholism. The former supplied information about the course of their fathers' alcohol problems; all 66 men answered questions about their own drinking and drug use and completed the Tridimensional Personality Questionnaire. There were no significant relationships between any of the 18 questionnaire scores and a subject's quantity/frequency of drinking or his family history of alcoholism. There was only one significant correlation between the alcoholic fathers' type 2 characteristics, according to the type 1/type 2 theory, and the sons' questionnaire scores. The relevance of these findings to the theory is discussed.
