An Abbreviated Measure of Internal-External Locus of Control

Summary Summary An abbreviated scale of internal-external locus of control (I-E) was administered to a national probability sample of 4,330 males ranging from 16 to 26 years of age. Psychometric properties (distributional characteristics, scale reliability, and item-test correlations) of the abbreviated scale were found to be similar to the full 29-item Rotter I-E scale. Comparable factor structures were obtained for both black and white respondents. A significant race difference indicated that blacks gave more external responses than whites.
