Convergent and Discriminant Validity of the Locus of Control Construct.
Borich, Gary D.; Paver, Sydney W.
Eighty undergraduates were administered four self-report locus of control inventories, in order to evaluate the convergent and discriminant validity of four categories common to these inventories: chance, fate, personal control, and powerful others. The four inventories were: (1) Internal, Powerful Others and Chance scales; (2) James Internal External Locus of Control Scale; (3) Nowicki Strickland Locus of Control Scale; and (4) Rotter Internal External Locus of Control Scale. Pearson correlations were computed between methods (inventories), and traits (categories), to construct a multitrait-multimethod matrix, following the Campbell and Fiske model. Validity was evaluated by observing intercorrelations among cells in the matrix. Convergent validity was consistently demonstrated for only one category--fate; discriminant validity was not evident for any comparison category across the four instruments. Rates of validity over all comparisons were 66.6% for convergent and 12.5% for discriminant. One explanation for inconsistent findings across locus of control studies is that the multitrait-multimethod matrix accounts for more variability than the categories measured. (The appendix lists items in each instrument which measure chance, fate, personal control, and powerful others.) (CP)
