This is the first CF-specific health-related quality of life (HRQOL) measure validated in a Muslim country. Methods: Fifty-one children aged 6-13 years treated at four centers in Turkey and 30 parents participated in this cross-sectional study. Demographic characteristics and disease severity parameters were recorded for all participants. All participants completed the parent or child versions of CFQ-R and KINDL questionnaires at enrollment. Reliability and construct validity analysis were carried out. Results: Both children and parents endorsed a range of responses, with no evidence of floor or ceiling effects. Item-to-total correlations indicated that most items were more highly correlated with their intended scale than competing scales. Good internal consistency was found for majority of child and parent scales. CFQ-R scales correlated significantly with clinical indices of disease severity. Good evidence of convergent validity with a generic HRQOL scale was found. Conclusion: Turkish versions of CFQ-R Child and Parent instruments have demonstrated adequate reliability and validity and can be utilized in clinical trials or integrated into clinical evaluation and follow-up of Turkish children with CF. © 2012 Springer Science+Business Media B.V.EnglishAdolescentChildCross-Sectional StudiesCystic FibrosisFemaleHealth StatusHumansLanguageMaleParentsPsychometricsQuality of LifeQuestionnairesReproducibility of ResultsSickness Impact ProfileSocioeconomic FactorsTranslatingTurkeyadolescentarticlechildcross-sectional studycystic fibrosisfemalehealth statushumanlanguagemaleparentpsychological aspectpsychometryquality of lifequestionnairereproducibilitySickness Impact Profilesocioeconomicsstatisticstranslating (language)Turkey (republic)cystic fibrosisparentpsychologypsychometrystatistics and numerical dataTurkeyArticle10.1007/s11136-012-0152-4
