The purpose of this research was to study the relationship between role ambiguity and conflict and job satisfaction as perceived by dietitians in the United States. Role ambiguity scores for all dietitians were consistently low. Generalist dietitians, however, scored significantly higher in role ambiguity than dietitians who were heads of departments and dietitians who were in the other/private practice group. Role conflict scores were considerably higher for all dietitian groups than scores for role ambiguity. Yet, for most groups, role conflict scores were only slightly higher than mid-point. Generalist dietitians scored significantly higher in role conflict than did six other groups of dietitians. There were no significant correlations between role ambiguity or conflict and job satisfaction.
