Leicester Cough Questionnaire

The Leicester Cough Questionnaire (LCQ) is a validated tool designed to assess the impact of chronic cough on patients' quality of life. It evaluates physical, psychological, and social domains through 19 items.

The severity score for the LCQ is derived from the total score, which ranges from 3 to 21. Higher scores indicate a less severe impact of the cough on the patient’s quality of life.

To score the LCQ, patients rate each of the 19 items on a 7-point Likert scale. Scores for each domain (physical, psychological, social) are averaged, and then summed to create the total score.
