Prevalence of depressive symptoms in Japanese male patients with chronic obstructive pulmonary disease

Abstract

The prevalence of depressive symptoms differed when assessed with CES-D and HADS-D. The reasons behind this difference include the fact that HADS-D frequently detected depressive symptoms in patients with mild COPD as well as a tendency for HADS-D to be strongly influenced by education levels. In contrast, the severity of COPD was reflected in CES-D. It is possible that prevalence of depressive symptoms differs in accordance with the applied screening tool.
