Abstract A sample of (N = 216) certified public accountants was surveyed using modified versions of Rizzo et al.'s (1970) role ambiguity and role conflict questionnaire and Duncan's (1972) perceived environmental uncertainty questionnaire to determine whether these concepts are measurements of distinct constructs. The question of the distinctness of the scales has important implications for the integrity of prior research. The items which comprised each of the questionnaires were examined using latent variable analysis. The results indicated the construct validity of role ambiguity and role conflict, and support was found for the distinctness of role ambiguity, role conflict, and perceived environmental uncertainty.
Gregson et al. (Tue,) studied this question.
