As concern over illegal drugs and drug-related behavior is a relatively recent phenomenon, there are little data available on the correlates and/or determinants of drug-related attitude-behaviors. The research done generates confused and often conflicting results, largely due to failure to specify level of attitude-behavior measured. This project develops a scale of attitude-behavior toward drug users according to the Guttman Facet Theory. Measured variables determined to be potential predictors and/or correlates of drug-related attitude-Behaviors are: (1) demographic status; (2) socio-psychological status; (3) contact with drug users; and (4) political activism. An attitude-behavior questionnaire and a personal data questionnaire were administered to 666 individuals in five groups selected for their known range of attitudes toward drug users. Results suggest that political activism and efficacy do not consistently predict attitude behavior. Factors which appear to account for significant portions of the variance are: (1) voting behavior; (2) participation in rallies; (3) contact with drug users; and (4) efficacy. The attitude behavior scale developed in this study may be of help in future research relating different predictors of drug-related attitude behavior to different subgroups. (Author/NMF)
