A comparative investigation of three measures of role ambiguity

Abstract

Examined the psychometric properties of 3 measures of role ambiguity (J. R. Rizzo et al, 1970; T. F. Lyons 1971; T. A. Beehr, 1976). Data relevant to both the psychometric equivalence and the validity of the 3 measures were gathered from 101 workers in the production department of a large midwestern organization. Results show that no single ambiguity measure was superior to the other measures. In addition, the 14 items comprising the 3 ambiguity measures were combined into a composite scale. Although this longer composite scale was psychometrically stronger than the shorter ambiguity measures, results raise doubts about the validity of all of the role ambiguity measures.
