Subjective Expected Utility,Locus of Control,and Behavior1

Although a fundamental assumption of behavior decision theory is that individuals must generally believe they can control their fate if their behavior is to be influenced by subjective expected utility (SEU), the hypothesis that the positive relationship between SEU and behavior is stronger for those with internal locus of control had not been directly tested. That hypothesis was assessed in two separate longitudinal studies of adolescents. The behavior studied in one sample was the initiation of cigarette smoking, and in the other it was the onset of drinking alcohol. The hypothesis received weak support in both studies.
