Approximately how long does it take a patient to complete the LCQ?
Answer: Less than 5 minutes
The LCQ takes approximately 3–5 minutes to complete, making it practical for routine clinical use.
Why is the LCQ considered superior to generic quality of life tools such as the SF-36 for cough patients?
Answer: It is disease-specific, capturing cough-relevant impacts not measured by generic tools
Disease-specific tools like the LCQ capture cough-specific impacts with greater sensitivity to change than generic measures like the SF-36.
The LCQ has been translated into multiple languages. What process is recommended for producing a valid translation?
Answer: Forward-translation, back-translation, cognitive debriefing, and cultural adaptation
Rigorous cross-cultural adaptation requires forward-translation, back-translation, reconciliation, and cognitive debriefing to ensure equivalence.
Which regulatory body's guidelines have recognized patient-reported outcome tools like the LCQ as acceptable endpoints in clinical trials?
Answer: FDA
The FDA's 2009 PRO guidance recognizes patient-reported outcome measures like the LCQ as valid endpoints for demonstrating treatment benefit in clinical trials.
What characteristic of the LCQ allows it to detect responsiveness to treatment over time?
Answer: Its 7-point Likert scale providing sufficient response variance
The 7-point Likert scale on each item provides sufficient variance to detect clinically meaningful changes in response to treatment.
The development of the LCQ was motivated in part by the lack of:
Answer: Validated patient-reported outcome measures specific to chronic cough
At the time of its development, there were no validated chronic-cough-specific patient-reported outcome measures, which the LCQ was created to address.
