Prevalence of depressive symptoms in Japanese male patients with chronic obstructive pulmonary disease.
The objective of this study was to utilize commonly applied tools, the Hospital Anxiety and Depression Scale - Depression subscale (HADS-D) and the Center for Epidemiological Studies Depression Scale (CES-D), to screen for depressive symptoms in patients with stable chronic obstructive pulmonary disease (COPD). Furthermore, we sought to identify whether differences existed in the prevalence of depressive symptoms as assessed by CES-D and HADS-D, and predictors of depressive symptoms. ⋯ 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.
