Abstract
Aim: of the study was to validate the Turkish version of Leicester Cough Questionnaire and use for Turkish patients with cough.
The questionnaire was translated into Turkish by using appropriate translation steps. The lettered patients over 18 years old who had no psychological diseases included into the study.The patients social-demographic data were recorded. After clinical examination,Turkish questionnaire had been applied to the patients.For reliability analysis, internal consistency and test-retest method were used. Cronbach alpha coefficent and item-total statistics were calculated for each question and subscales.The questionnaire had been applied to 100 patients twice with the interval of two weeks to quantify test-retest reliability.For validation the questionnaire is compared withSF-36 andWHOQOL-BREF-TR which were validated before in Turkish.
58 female,42 male total 100 chronic cough patients who had been followed at Celal Bayar University Chest Disease Department and 100 control group were included into the study between July 2013-July 2014.Mean age of patients was 44,7±16,4 years.For internal consistency,cronbach alpha coefficients of all subscales ranged between 0,73-0,89and calculated as 0,92 for total index. In test-retest reliabilty, the correlation coefficient ranged between 0,598-0,788 for each question and calculated as r=0,905 for total LCQ score. (p<0,001) For validity analysis, relationship betweeen mean LCQ and SF-36 and WHOQOL-BREF-TR scores were searched and a strong statistical correlation coefficient was found(p<0,05).
Our study indicates that the Turkish version of LCQ has been found to have acceptable reliability and validity for use in Turkish patients with cough.
