LCQ LCQ Scoring and Calculation 3

Question 1

What response scale does each LCQ item use?

Accepted Answer

7-point Likert scale

Answer

Each LCQ item uses a 7-point Likert scale ranging from 1 (all of the time) to 7 (none of the time).

Question 2

What time frame does the LCQ ask patients to reflect upon when answering?

Accepted Answer

Past 2 weeks

Answer

The LCQ asks patients to consider their cough-related experiences over the past 2 weeks.

Question 3

If a patient answers '1' on every LCQ item, what does this represent?

Accepted Answer

Cough impacts present all of the time — worst quality of life

Answer

A response of 1 means 'all of the time,' so scoring 1 on every item reflects the maximum cough burden and worst quality of life.

Question 4

When computing an LCQ domain score, what happens if a patient skips one item in that domain?

Accepted Answer

The mean is calculated from the completed items only

Answer

Standard scoring guidelines allow computing the domain mean from completed items when a small number of items are missing.

Question 5

Which score on the LCQ total scale suggests a clinically severe cough quality of life impairment?

Accepted Answer

Score below 11

Answer

Lower LCQ total scores indicate greater impairment; scores below 11 generally reflect severe cough-related quality of life burden.
