The Expanded Sense of Mission Scale was developed to identify the association between the “expanded sense of mission” and stress reactions. We developed 44 items concerning the expanded sense of mission. Workers (N=313) responded to these items, as well as to the Japanese version of the Utrecht Work Engagement Scale, and the Brief Job Stress Questionnaire. Results of factor analyzing the responses to the items on the expanded sense of mission extracted four factors: “Contribution to society,” “Contribution to colleagues,” “Upskilling-oriented nature of work” and “Directions for developing new businesses.” These factors consisting of 19 items were included in the new Expanded Sense of Mission Scale. Moreover, the reliability and the criterion-related validity of the Expanded Sense of Mission Scale was confirmed.
