There are specific questionnaires that assess physical activity fatigue in children, Children Sport Fatigue Questionnaire (CSFQ) and Short Fatigue Questionnaire (SFQ).Objective: To validate the Spanish version of both questionnaires in healthy sportive children and to measure the sensitivity of both tools on children with CF that follow regular physical activity.Methodology: After the questionnaires translation and retro-translation, they were applied in 44 healthy sportive children twice. Sensitivity was measured in 20 children with CF and the results were compared with the Cystic Fibrosis Questionnaire Revised (CFQ-R).Results: Healthy children: age (12±2.6 years), BMI (19±2.7 kg/m2). Cronbach index showed good consistency, 0.86 to 0.78, CSFQ and SFQ and intraclass correlation coefficient showed: 0.85 and 0.83, CSFQ and SFQ, respectively. CF children: age (13±3.8 years), BMI (18±2.7 kg/m2). Significant correlations were obtained between CFQ-R and CSFQ: Physical 0.76, Body 0.66 and Role 0.85 for CFQ-R14+; Digestive 0.34 and Treatment 0.33 for CFQ-R Child. Correlations between CFQ-R and SFQ: Physical 0.53 and Role 0.54 for CFQ-R14+, and Treatment 0.40 for CFQ-R Child.Conclusion: The CSFQ and SFQ questionnaires are valid and reliable for assessing the fatigue caused by physical activity and being suitable for use in CF children that follow regular physical activity such us pulmonary rehabilitation.Sponsored by: Proyecto AVANZA, TSI-020110-2009-431.
