Leicester Cough Questionnaire
Introduction[edit | edit source]
Leicester Cough Questionnaire (LCQ) is an English-born self-reporting quality of life measure of chronic cough, developed by S.S. Birring[1]. It consists of 19 items with a 7 point likert response scale (range from 1 to 7), a format example is available here. Each item is developed to assess symptoms during cough and impact of cough on three main domanins: physical, psychological and social. Scores are calculated as a mean of each domain and total score is calculated by adding every domain score. It generally takes about 5 minutes to be completed and it is designed for adults. Since the first development in 2003 LCQ has been translated and validated in several languages (Dutch[2], French[3], Korean[4], Lithuanian[5], Mandarin Chinese[6], Polish[7], Portuguese[8], Spanish[9], Swedish[10], Thai[11]). LCQ has been used as an outcome measure for different respiratory diseases like COPD[3][10][12], Cystic Fibrosis[13], non-CF bronchiectasis[6][14].
Objective[edit | edit source]
This instrument has been developed to detect the effect of chronic cough on health status and consequently on quality of life of chronic respiratory diseases patients. Patients are asked 19 questions reflecting on their cough over the previous two weeks including areas of; chest or stomach pain, sputum, embarrassment, anxiety, sleep disruption and energy.
Clinimetric properties of LCQ[edit | edit source]
The LCQ has been shown to be a valid and reliable health status measure for adults with chronic cough[1]. Concurrent validity measures how much a test correlates well with another measure that has previously been validated.

All data are expressed as r-correlation coefficient between total scores of each instruments listed and are all statistically significant unless specified.
Repeatability or test–retest reliability reflects the agreement between the results of successive measurements of the same "test" or "instrument" that occurs under the same conditions of the previous measurement
