LCQ LCQ Research and Comparative Studies 3

Question 1

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

Accepted Answer

Criterion or concurrent validity assessment

Answer

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.

Question 2

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

Accepted Answer

More than 15 languages

Answer

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

Question 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:

Accepted Answer

Discriminant validity

Answer

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

Question 4

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

Accepted Answer

All three domains — physical, psychological, and social

Answer

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

Question 5

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

Accepted Answer

0.70–1.0, indicating good to excellent reliability

Answer

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