The purpose of this study was to compare differences in role conflict, self efficacy, job satisfaction, and job involvement perceived by school nutrition teachers and dietitians. A total of 335 female school nutrition teachers and dietitians from Incheon area were surveyed by a self-report questionnaire in November 2010. Collected data were processed using SPSS 15.0. The reliability of the questionnaire was tested and differences between the two groups were analyzed using the Student's t-test, the chi-square test, and a two-way analysis of variance (ANOVA). The job satisfaction level of nutrition teachers was higher than that of dietitians. The effect of role conflict and job satisfaction for nutrition teachers and dietitians was different according to age. In addition, self-efficacy, job satisfaction, and job involvement of nutrition teachers and dietitians were influenced by their annual salaries. The frequency of meals served also affected role conflict, job satisfaction, and job involvement of the nutrition teachers and dietitians, and the effect of job involvement by the nutrition teachers and dietitians was different according to meal service type. Therefore, it is necessary to establish strategies for resolving role conflicts among school foodservice specialists and improve their self-efficacy for enhancing consumer's satisfaction with the general quality of school food service. These efforts may contribute to job satisfaction and job involvement of food service specialists and ultimately to the productivity of food service and the establishment of food service specialist roles.
