Reliability and Validity of the I,P, and C Scales - A Multidimensional View of Locus of Control.

Abstract

The paper contains a discussion of the modification of Rotter's Internal External Scale into the three scales of Internal, Powerful Others, and Chance orientations. The tripartite, multidimensional view of locus of control was developed because the validity and usefulness of Rotter's lumping expectancies of fate, chance, and powerful others together under the rubric of external control were questioned. Data are provided indicating that the refinement of the Internal External scale is justified. The three predicted orientations emerged in factor analyses, and scores on the scales were differentially related to such variables as philosophy of human nature, involvement, information, activism, psychopathology, and perceived parental upbringing.
