Smoking-Specific Locus of Control

Abstract

A smoking-specific locus of control scale was developed by modifying a drinking-related locus of control scale. The new scale, Rotter's I-E scale, and a smoking questionnaire were administered to 70 subjects. Estimates of reliability indicated that the new scale had reasonably high internal consistency. Scores differed as a function of subjects' reports of their addiction to cigarettes but not as a function of their current smoking status. 15 addicted individuals scored more externally on the new scale than did 24 nonaddicted individuals. There were no differences for scores on the Rotter I-E scale as a function of reported addiction or smoking status. The new scale appears to be a more sensitive measure of locus of control than Rotter's scale. The two locus of control scales were not significantly correlated, indicating their independence. Individuals apparently maintain a distinct locus of control for smoking rather than having a general expectation for control.
