what specific dimensions of these complex constructs cause this positive influence. Here, further studies are necessary, which focus on the partial dimensions in detail. In summary, Table 2 provides a comprehensive overview of the state of research on empirically confirmed statistically significant determinants and their dimensions on the respective characteristic levels. This table summarizes the identified significant results and makes clear what really matters in regard to the support of transfer of training. Overall, our analysis shows for the organizational level of the work environment, that transfer of training indicates positive relationships. The two most important determinants of the transfer within this level are social support and structural and organizational circumstances in the workplace. The focus of previous research was on the determinant of social support, however. Numerous studies confirm the positive influence of social support from colleagues and from supervisors, particularly in regard to the role played by feedback. Only a single study indicates an inconsistency in research findings regarding the determinant of support by supervisors. Further studies should investigate in detail which specific dimensions of support, beyond feedback, cause this positive influence. This also applies to the variables of structural and organizational circumstances in the workplace, identified in previous research. Only a handful of studies have investigated these, thus far. The dimensions of the determinant of organizational culture have already been partially incorporated in research.
