There is no a singleitem global quality of life scale for routine clinical practice for adult patients with cystic fibrosis. We assessed the reliability and validity of a single-item global quality of life scale and compared with the Cystic Fibrosis Quality of Life Questionnaire CF-QOL for adult patients with cystic fibrosis. Method 121 men 66 women 55 adult cystic fibrosis patients self-completed the CF-QOL the Hospital Anxiety Depression Scale and the single item global quality of life scale at the out patient clinic. 33 17 women completed the repeat questionnaires at home within two weeks. Socio-demographic characteristic and lung function data were extracted from the recent medical notes. Results Mean SD age was 29.6 8.9 years and mean SD forced expiratory volume in 1 second was 2.20 0.94 litres. The test-retest reproducibility using the intra-class correlation coefficient ICC for the CF-QOL was 0.83 95 confidence interval 0.68 to 0.91. The single item global quality of life ICC score was 0.78 95 confidence interval 0.59 to 0.88. Concurrent validity of the single-item global quality of life was examined in relation to all items of the CF-QOL frequent episodes of readmission anxiety and depression all p 0.01 were moderately correlated. Conclusion The study provides preliminary evidence that the single-item quality of life scale is acceptable valid and repeatable for adult patients with cystic fibrosis. It is a promising tool .
