Organizational commitment has been conceptualized and measured in various ways. The two studies reported here were conducted to test aspects of a three‐component model of commitment which integrates these various conceptualizations. The affective component of organizational commitment, proposed by the model, refers to employees' emotional attachment to, identification with, and involvement in, the organization. The continuance component refers to commitment based on the costs that employees associate with leaving the organization. Finally, the normative component refers to employees' feelings of obligation to remain with the organization. In Study 1, scales were developed to measure these components. Relationships among the components of commitment and with variables considered their antecedents were examined in Study 2. Results of a canonical correlation analysis suggested that, as predicted by the model, the affective and continuance components of organizational commitment are empirically distinguishable constructs with different correlates. The affective and normative components, although distinguishable, appear to be somewhat related. The importance of differentiating the components of commitment, both in research and practice, is discussed.

The authors tested the generalizability of J. P. Meyer and N. J. 3-component model of organizational commitment to the domain of occupational commitment. Measures of affective, continuance, and normative commitment to occupation were developed and used to test hypotheses concerning their differential relations with antecedent and consequence variables. Confirmatory factor analyses conducted on data collected from samples of student and registered nurses revealed that the 3 component measures of occupational commitment were distinguishable from one another and from measures of the 3 components of organizational commitment. Results of correlation and regression analyses were generally consistent with predictions made on the basis of the 3-component model and demonstrated that occupational and organizational commitment contribute independently to the prediction of professional activity and work behavior.

To investigate the role of affect and cognitions in predicting organizational citizenship behavior (OCB) and workplace deviance behavior (WDB), data were collected from 149 registered nurses and their coworkers. Job affect was associated more strongly than were job cognitions with OCB directed at individuals, whereas job cognitions correlated more strongly than did job affect with OCB directed at the organization. With respect to WDB, job cognitions played a more important role in prediction when job affect was represented by 2 general mood variables (positive and negative affect). When discrete emotions were used to represent job affect, however, job affect played as important a role as job cognition variables, strongly suggesting the importance of considering discrete emotions in job affect research.
