The validity and reliability of the Turkish version of the Leicester Cough Questionnaire in COPD patients

Background/aim: The reliability and validity of the Turkish version of the Leicester Cough Questionnaire (LCQ) have been evaluatedbefore. This study aimed to validate the Turkish version of the LCQ in chronic obstructive pulmonary disease (COPD) patients withcough.Materials and methods: COPD (GOLD B, C, D) patients over age 40 (n = 75) and healthy volunteers as a control group (n = 75) wereincluded. A sociodemographic data form, the LCQ, the Short Form-36 (SF-36) quality of life questionnaire, and the World HealthOrganization Quality of Life Brief Form for Turkish people were completed. The internal reliability of the LCQ was determined usingthe Cronbach alpha coefficient (>0.6) and its repeatability by the intraclass consistency coefficient (P < 0.05) was accepted as significant.Results: For internal consistency, Cronbach alpha coefficients of all subscales of the LCQ, physical, psychological, and social, were foundas 0.72, 0.86, and 0.83, respectively, with 0.92 for the total index. There was significant internal consistency for all subscales and the totalindex (Cronbach alpha coefficients of >0.6). In test–retest reliability, the correlation coefficient ranged between 0.71 and 0.80 for eachquestion and was calculated as r = 0.89 for total LCQ score (P < 0.001).Conclusion: The Turkish version of the LCQ has been found to have acceptable reliability and validity for use in Turkish COPD patientswith chronic cough.
