Development of a Scale to Measure Motivation for Part-Time Employment of International Students in Japan

Abstract

The purpose of this study, which was based on the self-determination theory, was to develop a scale to measure motivation for part-time employment among international students in Japan. In Part I of this study, we asked for responses to 40 items selected in a preliminary survey. The results of a factor analysis indicated that the scale was composed of the following five factors: intrinsic, integrated, identified, introjected, and external regulation. In addition, the correlation analysis among the factors confirmed that the correlation coefficients were highest for types of motivation that were theoretically closest to one another. Furthermore, correlation coefficients for the job satisfaction scale were highest for motivation types with the highest level of self-determination. Part II of this study showed that test-retest reliability was adequate. These results showed that the scale had sufficient reliability and validity and that its score could predict job satisfaction.
