Supervisor support, peer support and transfer motivation have been identified as important predictors of training transfer. Transfer motivation is thought to mediate the support-training transfer relationship. Especially after team training interventions that include all team members (i.e. whole-team training), individual perception of these factors might be shared among team members. However, an integration of the team level in the training transfer process is rare, yet still needed. Analyzing 194 employees from 34 teams in the context of whole-team training interventions, we found similar relationships and processes at both levels of analysis: social support enhances transfer motivation at the individual and team levels. Furthermore, motivation to transfer increases training transfer and serves as a connecting mechanism in the social support-training transfer link. The results underline the importance of: (1) considering multiple levels in theories and research about the training transfer process; and (2) ensuring the practice of individual-directed support and a shared, supportive climate within teams.
