This study examines the relationship between employee attitudes toward training and feelings of organizational commitment among a sample of 337 registered nurses from five hospitals. Using social exchange theory as a framework for investigating the relationship, the researcher found that perceived access to training, social support for training, motivation to learn, and perceived benefits of training are positively related to organizational commitment. Using a three-component model of organizational commitment, the strongest relationships appear with the affective form of commitment. The relationship between perceived access to training opportunities and the affective form of organizational commitment is moderated by job satisfaction but not job involvement. The findings are discussed for their theoretical and practical application to HRD, for the management of HRD in health care settings, and for researchers interested in outcomes of HRD.
