The measurement of locus of control: assessing more than meets the eye?

Ambiguities in the conceptions and measurement of locus of control were investigated in this study. Specifically, some psychometric properties of several widely used measures of perceived behavior-outcome contingency, interpersonal power, and social self-efficacy were assessed. To different degrees, the results indicated that all three measures of perceived behavior-outcome contingency lacked convergent and discriminant validity. Implications for interpreting past research, directions for future investigations, and limitations of the present study are discussed.
