It is noteworthy that the interaction of intrinsic motivation and positive affectivity
lessens depression. Intrinsic motivation and positive affectivity appear to be the two
personal resources that work together to shield employees from experiencing elevated
levels of depression. That is, employees with more personal resources can control their
work environment and protect themselves from experiencing depression. This is
consistent with the COR theory (Hobfoll, 2001) and the findings of a similar study (see
Zellars et al., 2006).
