The purpose of this study was to develop a scale measuring multi-faceted work motivations in
Japanese organizations. It also sought to verify the scale’s validity and reliability. In study 1, items of the
scale were developed based on Barrick, Stewart, and Piotrowski’s (2002) work on a prior scale, and
included additional content on motivational aspects of learning. These items were further elaborated and
examined in preliminary investigation to determine whether each reflected three core dimensions:
directivity, persistence, and strength. In study 2, web surveys comprising the items were administered to
600 Japanese employees whose responses were later analyzed. An exploratory factor analysis was
performed to ascertain the scale’s validity and reliability, which revealed 4 factors: accomplishment,
competition, cooperation, and learning-oriented motivation. In study 4, a longitudinal survey was
administered to 300 Japanese employees to determine test –retest reliability and relationship between
work motivation and job performance. The results generally supported the reliability and validity of the
multi-faceted work motivations.
