Subscribe/Renew Journal
Background: Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease associated with a high level of disability, the treatment of which is aimed at reducing symptoms, increasing function and improving the quality of life of the patient with lot of emphasis been given to the development of a Health Related Quality Of Life (HRQOL) questionnaire. St. George's Respiratory Questionnaire (SGRQ) is a self administered validated questionnaire used in COPD. The Clinical COPD Questionnaire (CCQ) was developed as a simple tool to help clinicians identify the clinical status of airways in individuals with COPD. Hence there is a need to validate the CCQ to identify the health status of those with COPD in Indian population.
Aims: To measure and compare the scores and time taken with SGRQ and CCQ respectively in COPD subjects.
Methodology: A convenience sample of 35 COPD subjects, were asked to answer the SGRQ and CCQ.
Results: Pearson correlation and Student's t-test were used for statistical analysis and it was found that the three individual components of CCQ correlated with those of the SGRQ (r =0.909, p
Conclusion: CCQ can be considered at par with SGRQ to assess the HRQOL in individuals with COPD in South Indian population.
