Objective: To evaluate the psychometric properties of the Spanish versions of the child- and parent-report cystic fibrosis questionnaire-revised (CFQ-R).

Methods: A Spanish adaptation of the CFQ-R was performed; 68 children with CF (6-13 years) and their parents completed the child- and parent-report CFQ-R, respectively, and the Revidierter KINDer Lebensqualitätsfragebogen (KINDL) questionnaire. The CFQ-R was completed twice, 7-10 days apart, and its psychometric properties were analyzed.
