We aimed to test whether the Liverpool Respiratory Symptom Questionnaire (LRSQ) could distinguish well, pre-school and older children with and without CF,\u00a0whether it could distinguish well and unwell children with CF and, finally, whether LRSQ scores in older children with CF correlated with established measures of disease severity.<\/jats:p><jats:p>20 stable pre-school children with CF had significantly higher total LRSQ scores than 51 pre-school controls, and higher scores in two out of eight domains. Similarly, 21 stable 6- to 12-yr-old children with CF had higher total scores than 97 6- to 12-yr-old controls, and higher scores in seven out of eight domains.<\/jats:p><jats:p>In older children with CF, LRSQ scores correlated negatively with Shwachman score and forced expiratory volume in 1 s (r= -0.58, p&lt;0.001, n=31; and r= -0.46, p&lt;0.010, n=34, respectively). Within the CF group, patients who cultured<jats:italic>Pseudomonas aeruginosa<\/jats:italic>, who used more \u201cback-up\u201d antibiotics or whose school attendance was lower also had higher LRSQ scores.<\/jats:p><jats:p>The LRSQ differentiates well children from those with CF in both pre-school and the 6- to 12-yr-old age group, even at a point of stability. It also differentiates stable from unwell children with CF, and scores correlate with other measures of respiratory disease, highlighting its potential as a clinical monitoring tool in paediatric CF.<\/jats:p>","DOI":"10.1183\/09031936.00070311","type":"journal-article","created":{"date-parts":[[2011,9,2]],"date-time":"2011-09-02T00:59:55Z","timestamp":1314925195000},"page":"899-905","source":"Crossref","is-referenced-by-count":14,"title":["Assessing the Liverpool Respiratory Symptom Questionnaire in children with cystic fibrosis"],"prefix":"10.1183","volume":"39","author":[{"given":"R.","family":"Trinick","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.W.","family":"Southern","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.S.","family":"McNamara","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2011,9,1]]},"reference":[{"key":"2024102020490888000_39.4.899.1","doi-asserted-by":"publisher","DOI":"10.1136\/thx.49.9.860"},{"key":"2024102020490888000_39.4.899.2","doi-asserted-by":"publisher","DOI":"10.1513\/pats.200703-040BR"},{"key":"2024102020490888000_39.4.899.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcf.2009.09.003"},{"key":"2024102020490888000_39.4.899.4","doi-asserted-by":"publisher","DOI":"10.1016\/j.prrv.2008.05.003"},{"key":"2024102020490888000_39.4.899.5","doi-asserted-by":"publisher","DOI":"10.1097\/01.mlr.0000258615.42478.55"},{"key":"2024102020490888000_39.4.899.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcf.2009.04.003"},{"key":"2024102020490888000_39.4.899.7","doi-asserted-by":"publisher","DOI":"10.1093\/jpepsy\/jsg044"},{"key":"2024102020490888000_39.4.899.8","doi-asserted-by":"publisher","DOI":"10.1136\/thorax.55.11.946"},{"key":"2024102020490888000_39.4.899.9","doi-asserted-by":"publisher","DOI":"10.1007\/s10880-009-9179-2"},{"key":"2024102020490888000_39.4.899.10","doi-asserted-by":"publisher","DOI":"10.1378\/chest.08-1190"},{"key":"2024102020490888000_39.4.899.11","doi-asserted-by":"publisher","DOI":"10.1136\/adc.87.5.376"},{"key":"2024102020490888000_39.4.899.12","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.306.6889.1386"},{"key":"2024102020490888000_39.4.899.13","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.20376"},{"key":"2024102020490888000_39.4.899.14","doi-asserted-by":"publisher","DOI":"10.1016\/S1569-1993(02)00141-8"},{"key":"2024102020490888000_39.4.899.15","doi-asserted-by":"publisher","DOI":"10.1378\/chest.128.4.2347"},{"key":"2024102020490888000_39.4.899.16","unstructured":"Nunnally J Bernstein I , eds.
