Purpose: This study aimed to translate the Leicester Cough Questionnaire (LCQ) into Urdu language and to test the validity, and reliability of the LCQ into Urdu version called LCQ-U, in those patients who have chronic respiratory conditions.

To test reliability, the LCQ-U was repeated after 2 weeks. The cough severity was also assessed by using the Cough visual analogue scale.
Results: Analysis of concurrent validity showed that LCQ has a strong negative correlation with the Cough Visual Analogue Scale (r = - 0.89, P>0.05). The LCQ-U indicated a strong correlation (r = 0.965, P
