The Motivation at Work Scale (MAWS) was developed in accordance with the multidimensional conceptualization of motivation postulated in self-determination theory. The authors examined the structure of the MAWS in a group of 1,644 workers in two different languages, English and French. Results obtained from these samples suggested that the structure of motivation at work across languages is consistently organized into four different types: intrinsic motivation, identified regulation, introjected regulation, and external regulation. The MAWS subscales were predictably associated with organizational behavior constructs. The importance of this new multidimensional scale to the development of new work motivation research is discussed. (Contains 5 tables.)
