  1. The LCQ has been used to validate new cough assessment tools. This process is called:

    Answer: Criterion or concurrent validity assessment

    Using the LCQ as a gold standard to validate new tools is a form of criterion or concurrent validity assessment, establishing whether new measures agree with the established standard.

  2. In global chronic cough research, the LCQ has been translated into approximately how many languages?

    Answer: More than 15 languages

    The LCQ has been translated and cross-culturally adapted into more than 15 languages, enabling its use in international multicenter trials.

  3. Research has shown that the LCQ can differentiate between patients with refractory chronic cough and those with cough that responds to first-line treatment. This is called:

    Answer: Discriminant validity

    The ability of the LCQ to distinguish between clinically different patient groups (refractory vs. responsive cough) demonstrates discriminant validity.

  4. In studies evaluating speech pathology cough suppression therapy (CST), the LCQ demonstrated improvements primarily in:

    Answer: All three domains — physical, psychological, and social

    Research on CST shows significant improvements across all three LCQ domains, reflecting the broad quality of life benefits of effective cough suppression.

  5. The LCQ's test-retest reliability, assessed in stable patients, is typically reported as an intraclass correlation coefficient (ICC) of:

    Answer: 0.70–1.0, indicating good to excellent reliability

    The LCQ demonstrates good to excellent test-retest reliability with ICC values typically above 0.70 in stable patient populations.

  6. Future research directions for the LCQ include development of a digital ePRO (electronic patient-reported outcome) version. The primary advantage of this would be:

    Answer: Enabling real-time data capture, reducing recall bias and improving trial efficiency

    An ePRO version of the LCQ would allow real-time, ecological momentary data capture, reducing reliance on retrospective recall and improving data quality in clinical trials.
