The COR theory contends that individuals with more resources can protect themselves
from experiencing strains (Hobfoll, 2001). Under these circumstances, such individuals
are likely to be confronted with less depressive symptoms. A recent empirical study
demonstrated that conscientiousness strengthened the negative relationship between
positive affectivity and strain variables (i.e. exhaustion, depersonalization, and job
tension) (Zellars et al., 2006). Similarly, this study posits that positive affectivity,
coupled with intrinsic motivation, can make employees control their work environment
and cope with emotional exhaustion and depression better. Assessing such
relationships is significant, since empirical evidence in the relevant literature
pertaining to the joint effects of two personal resources on strains and depression is
meager (see Zellars et al., 2006).
