COPD Assessment Test Can Predict Depression

COPD Assessment Test Can Predict Depression

The frequency of depression in COPD patients are substantial and early detection and prevention of depression is critical.

Recently, COPD assessment test (CAT) was developed and validated to assess the impact of COPD on patients' quality of life.

In this prospective study, we will investigate the predictive utility of CAT for predicting depression in COPD patients.

This study is aimed to investigate the association between the COPD Assessment Test (CAT) and depression in stable COPD patients. Stable COPD patients will be enrolled from the tertiary hospitals. All patients will undergo lung function tests. The Korean versions of the CAT (COPD assessment test) and Patient Health Questionnaire-9 (PHQ-9) will be used to assess COPD symptoms and depressive disorder, respectively.

We will compare the depresssion frequency among GOLD classifications of airway limitation and among the four CAT groups. And. we will also investigate which items of the CAT are the strongest indicators of depression.

Inclusion Criteria:

• COPD patients who aged > or = 40 years

Exclusion Criteria:

• acute exacerbation within 3 months
