Abstract:Chronic Obstructive Pulmonary Disease (COPD) is often caused by years of smoking. The consequences range from shortness of breath to total disability. Since the treatment of COPD is aiming for an improvement of health related quality of life (HRQL), it is important to accurately measure both the improvement and deterioration of the HRQL. The Saint George Respiratory Questionnaire (SGRQ) owns the status of the legacy questionnaire in the HRQL research of COPD patients. The objectives of this study were to assess the experiences of COPD patients while completing the Saint George Respiratory Questionnaire for COPD patients (SGRQ-C) and to suggest whether to include items of the SGRQ-C into the item bank of a CAT measuring the quality of life for COPD patients. Twenty COPD patients from the Medisch Spectrum Twente (MST) participated in the study. We applied the Three Step Test Interview (TSTI) to explore misinterpretations and other problems in answering the SGRQ-C items. Respondents had major problems with the interpretation of terms like ‘physical exercise’, ‘sports’, ‘games’ and ‘housework’ used in items 25, 35 and 38. Respondents asked for a third response option between the two response choices ‘true’ and ‘not true’, which were used for 31 items. Moreover, respondents did not read the questions instructions properly and therefore produced a lot of missing data. Overall, respondents were satisfied with the SGRQ-C items. The problems that were found might have been avoided by using the TSTI method during the development of the SGRQ and SGRQ-C. All items except for items 25, 32 and 39 can be included into the item bank of the CAT, after small adjustments.
