Idiopathic scoliosis (IS) can significantly alter the quality of life of adolescents. Some of the available questionnaires in French measuring the quality of life in this population show weak psychometric properties. The newly developed Italian Spine Youth Quality of Life (ISYQOL) questionnaire promises better properties.To provide a French-Canadian version of the ISYQOL and to verify its psychometric characteristics.Prospective validation of a cross-cultural adaptation of the ISYQOL questionnaire.A total of 111 participants with idiopathic scoliosis (77.5% female, 10-18 years old, mean Cobb angle=28°) were included in the study.The French-Canadian version of the Italian Spine Youth Quality of Life (ISYQOL-F) questionnaire.The ISYQOL was translated into French using a forward-backward approach. We then verified the understanding of the translated items with two scoliosis experts and 10 adolescents. Afterward, 111 adolescents with IS were recruited by convenience at the scoliosis clinic and they completed the ISYQOL on three occasions (before seeing the specialist, 1 week, and 2 weeks after). Cronbach's alpha, intra-class (ICC), and Pearson correlation coefficients were used to respectively determine internal consistency, test-retest reliability, and concurrent validity with the SRS-22r and SF-12. The standard error of measurement (SEM) and 95% confidence minimal detectable change (MDCThe ISYQOL-F showed good internal consistency with a Cronbach alpha of 0.81 and 0.85 respectively for items 1-13 (n=55; ISYQOL-F mean score ± SD = 63.9±13.5) and 1-20 (n=56; ISYQOL-F mean score ± SD=60.7±10.3). Test-retest reliability was excellent (ICCThe internal consistency and reliability of ISYQOL-F are good. The total score correlates moderately with the SRS-22r and SF-12. Unlike SRS-22r, the ISYQOL-F does not appear to have a ceiling effect. The ISYQOL-F may thus be suitable to assess quality of life in a population of French-Canadian adolescents with IS.
