| Abstract: | ABSTRACt The purpose was to investigate the relationship between autonomy support by managers and co-workers and employees' work motivation and self-efficacy in two studies. In Study 1, a sample of 343 Swedish workers completed surveys, and in Study 2, we followed up with a subsample of 98 workers one year later. As in previous studies, managers' support of autonomy was significantly positively related to workers' outcomes. However, the results of Study 1 also showed that co-worker autonomy support was related to these outcomes over and above the effects of manager support. Study 2 showed that changes in autonomy support from co-workers during one year significantly predicted motivation and self-efficacy one year later, while change in support from managers was unrelated to outcomes later. These findings provide evidence for the importance of both vertical and horizontal sources of support. |
