Abstract

The PHQ-9 is a standard screening tool for depressive disorders in cancer patients. As for the frequently reported symptom overlap with somatic disease, it has been debated whether somatic items are suitable for identifying depressive disorders in cancer patients. Thus, this study examines the diagnostic accuracy of somatic versus cognitive-emotional PHQ-9 items.
