This study expanded upon Green (2014)’s study and examined the unique contributions of fatigue, pain, and functional limitation to future depression (depression measured at a later point in time) in cancer survivors. The findings demonstrate that functional impairment and fatigue are both strongly associated with subsequent depression. These findings follow from and are consistent with Green’s (2014) study, and demonstrate that functional impairment and fatigue strongly impact ongoing and future depression, with higher levels of functional impairment and fatigue being associated with higher levels of future depression. As a whole, the findings of this study are commensurate with prior research. This study extends these findings to survivors of cancer, and demonstrates the need for further research related to the development and progression of depression in cancer patients and provided additional empirical support for fatigue management training among cancer survivors.
