What this trial studies

This study aims to develop a validated tool called the Cough Control Questionnaire (CCQ) to assess the control of chronic cough, which affects a significant portion of the population. The research will be conducted in three phases: first, a literature review of existing tools; second, the development of the CCQ through patient focus groups and expert reviews; and third, the validation of the CCQ with patients suffering from chronic cough. The goal is to create a patient-focused measure that can evaluate treatment benefits in clinical and research settings.
