Application of the Tridimensional Personality Questionnaire to a population of alcoholics and other substance abusers.
To assess its construct validity and application, Cloninger's Tridimensional Personality Questionnaire (TPQ) was administered to 267 inpatient substance abusers. One hundred seventy-two of the patients were alcoholic, 47 abused stimulants, and 48 abused other drugs, primarily benzodiazepines, marijuana, or were polysubstance abusers. Of the sample 33.8% were female. Analyses were conducted to (1) determine whether TPQ scores could be used to classify alcoholics as either Cloninger Type I or Type II; (2) examine the intercorrelations of TPQ scales and identify differences in these patterns due to drug of choice; (3) replicate previously obtained gender differences on the TPQ. The results indicate that (1) TPQ scores did not classify the alcoholics into the expected frequencies for Type I and Type II; (2) the scales were not independent and did not give rise to any differences among drug user groups, but (3) did confirm previously reported gender differences. These results indicate that Cloninger's model and the TPQ must be subjected to careful empirical study prior to their widespread acceptance.
