Have we studied, should we study, and can we study the development of commitment? Methodological issues and the developmental study of work-related commitment

Abstract

The study of developmental trajectories involves examining how and why a measure or index of behavior changes over time. Within the huge body of work devoted to different forms of work commitment, very little has directly and explicitly addressed developmental issues. Theory suggests that some forms of work commitment develop prior to actual experience of the focus of the commitment (e.g., normative commitment and work ethic). For affective and continuance commitment, however, it has been hypothesized that experience is essential. In most instances, this experience is gained after entry into the work force and, specifically, into an organization. Therefore, understanding how these types of commitment develop and highlighting the factors related to tenure that cause changes in commitment will not only fill a gap in the empirical work and strengthen commitment theory, but will help managers to optimize the commitment of their employees. This paper outlines the current understanding of changes in commitment with time and describes a research method, taken from the developmental psychology literature, that overcomes some of the problems inherent to the approaches most frequently used to imply developmental change in organizational psychology. It concludes with suggestions for future research incorporating this method.
