1. A meta-analysis of cough PROs would rank the LCQ's internal consistency (Cronbach's alpha) as: → Good to excellent (alpha > 0.70)
2. How does LCQ performance differ in patients with neurogenic cough compared to other chronic cough etiologies? → LCQ scores are similarly reduced, reflecting the severe QoL burden of neurogenic cough
3. How frequently is the LCQ typically administered in a clinical trial to measure treatment outcomes? → Weekly
4. Which theoretical framework most closely guided the domain structure of the LCQ? → Biopsychosocial model of health
5. Which study design provides the strongest evidence for the LCQ's responsiveness to treatment? → Randomized controlled trials demonstrating score changes following effective treatment
6. What measure was used to define a stable population for test-retest reliability assessment? → Patient global impression of change (PGIC)
7. The LCQ was originally validated in which patient population, forming the foundation for its reliability evidence? → Adults presenting to a specialist cough clinic
8. A patient who stops attending religious services because they fear coughing during the service would have this captured in which LCQ domain? → Social domain
9. How does the LCQ compare to the Patient-Reported Outcomes Measurement Information System (PROMIS) tools for chronic cough? → LCQ is cough-specific; PROMIS tools are generic and not optimized for chronic cough QoL
10. What has research shown about the correlation between LCQ scores and objective cough frequency? → Modest-to-moderate correlation, indicating they measure related but distinct constructs
11. Which of the following activities is directly assessed in the LCQ social domain? → Ability to work or carry out daily activities
12. The LCQ has been used to demonstrate that chronic cough in interstitial lung disease (ILD) produces: → Substantial quality of life impairment comparable to or exceeding that in COPD
13. Which LCQ domain is most likely to show improvement earliest following effective antitussive therapy? → Physical
14. In a US chronic cough clinic, which combination of tools is most commonly recommended for comprehensive assessment? → LCQ (QoL) + ambulatory cough monitor (frequency) + VAS (severity)
15. Which of the following domains is NOT part of the LCQ? → Emotional
16. Feeling that coughing has taken over one's life is most likely captured in which LCQ domain? → Psychological domain
17. Which of the following is NOT typically assessed in the physical domain of the LCQ? → Feeling embarrassed in company
18. A patient scores 7 on every social domain item of the LCQ. This indicates: → No social impairment — they never experience cough-related social limitations
19. Can caregivers or proxies complete the LCQ on behalf of a patient? → No — it is a patient-reported outcome tool and requires self-completion
20. Who developed the Leicester Cough Questionnaire? → Birring and colleagues
21. Patients who report feeling that their cough makes them anxious would score closest to which value on relevant LCQ items? → 2 (most of the time)
22. Speech pathology cough suppression therapy (CST) has been shown to improve the LCQ psychological domain. This is primarily because CST: → Reduces anxiety by improving perceived control over coughing
23. How has the LCQ been used in patients with chronic cough secondary to gastroesophageal reflux (GERD)? → To monitor quality of life changes as reflux treatment is adjusted
24. A low score on the LCQ psychological domain in a patient with idiopathic chronic cough should prompt the clinician to consider: → Referring for psychological support or cognitive behavioral therapy
25. How was the initial item pool for the LCQ reduced to the final 19 items? → Item reduction via factor analysis and removal of redundant items
26. Does the LCQ assess the frequency or severity of cough directly? → No — it assesses impact on quality of life, not cough frequency/severity
27. Which of the following best describes what the LCQ psychological domain measures? → Emotional distress attributable to chronic cough
28. Which of the following is an example of a physical domain item on the LCQ? → Feeling tired due to coughing
29. Who developed the Leicester Cough Questionnaire? → Birring et al. at the University of Leicester
30. What is the primary purpose of the Leicester Cough Questionnaire (LCQ)? → To evaluate the impact of cough severity on quality of life in patients with chronic cough
