Accounting for Occupational and Organizational Commitment

Using longitudinal data collected from a subsample (N = 92) of subjects surveyed five years earlier by Shoemaker et al. (1977), the present study assesses the relative utility of two distinctly different approaches to the study of occupational and organizational commitment. The first is the structural investments or side-bet approach made famous by Becker (1960); the second, the attitudinal or social psychological perspective used by Ritzer and Trice (1969), among others. Based on regression analyses of data, for the two time periods studied and for changes across time, structural variables appear to be slightly better predictors of commitment than do attitudinal variables. Of particular note, however, are the changes in predictive power of each approach, relative to both occupational and organizational commitment, when comparing two distinct stages in the worker career of employees represented by the five-year span of the study.
