Cynical hostility is related to various sleep problems and
depression; however, it is not known if hostility relates to sleep independent
of depression. We hypothesized that hostility would negatively relate to
fatigue, as well as sleep quality and duration, but not independently of
depressive symptoms. Participants (62 men, ages 18-30; 55% White)
completed measures of depression (Beck Depression Inventory; Beck,
1987), cynical hostility (Cook-Medley Hostility Scale; Cook & Medley, 1954),
and sleep. Hostility correlated with fatigue, r(60) = .33, p < .01, but this
association did not remain after controlling for the effect of depression,
ΔR2= .24, p < .001, in a hierarchical linear regression analysis. The finding
that depression statistically accounted for the association between hostility
and fatigue suggests that depression is important to consider as a potential
mediator in prospective studies of hostility and sleep.
