Organizational commitment has been a matter of researchers' and practitioners' interest for a couple of decades, which was expected to increase productivity, to decrease turnover, tardiness, and absenteeism, and to indicate excellent culture of organizations. Recently Allen and Meyer's (1990) Three-Component Commitment Scale has been adopted worldwide and its high reliability and validity were substantiated. As was seen apparently, research attempts to translate original (English) version into other languages, such as, French and Korean, was prevalent. The purpose of this presentation was to develop, validate, and yield the scale and item characteristics of the Japanese version of Allen and Meyer's scale based on Japanese samples by Structural Equation Modeling (SEM) and Item Response Theory (IRT) techniques. Questionnaire assessing three dimensions of organizational commitment, job satisfaction (as correlate variable), workplace vitality, and depression tendency (as dependent variables) was completed by 2,024 employees across a variety of Japanese large-sized companies. Results indicated that the dimensionality of three components (Affective, Continuous, and Normative) of the commitment scale was confirmed with significant level of goodness of fit indices, and further validation with other criteria was also replicated. Scale and item characteristics yielded that affective and continuous commitment subscales functioned well to sensitively distinguish respondents with relatively high level of latent trait for each dimension.
