This study examined the impact of organizational commitment and valence on training motivation and, in turn, the impact of training motivation on posttraining self-efficacy. Data were collected from 264 part-time university athletic department employees both prior to and following a mandatory training session. Structural equation modeling indicated that organizational commitment (beta = .53, p < .001) and valence (beta = .26, p < .001) held positive associations with training motivation, accounting for 45% of the variance. Additionally, training motivation held a significant association with posttraining self-efficacy (beta = .37, p < .001), accounting for 13% of the variance. The results demonstrate (a) salient antecedents of training motivation, and (b) the importance of training motivation in realizing training outcomes within the context of university athletic departments.
