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.
