Scoliosis significantly impacts Quality of Life (QOL). Current quality of life questionnaires for adolescents with idiopathic scoliosis (AIS) have limitations. A new questionnaire for measuring QOL in AIS called the Italian Spine Youth Quality of Life (ISYQOL) has been developed to address these limitations but the English translation has not yet been validated. To determine the ceiling and floor effects, and the convergent validity of the ISYQOL questionnaire against established QOL questionnaires and Cobb angle in AIS. One hundred consecutive females with AIS, (10–18 years old), treated non-operatively. The English translation of the ISYQOL was compared to the following established questionnaires: Scoliosis Research Society-22r and the Spinal Appearance Questionnaire. The participants were 100 females (13.89+/-1.8 years) with 28.75+/-13.9° curve angles. The convergent validity of the ISYQOL score (60.3+/-12.44) was supported by significant correlation with the SRS-22r total score, function, pain, self-image, and mental health scores (r = 0.70, 0.54, 0.57, 0.52 and 0.50, respectively), and with the SAQ general, waist, and expectations domains (r = -0.6. -.52, and -0.56, respectively). Correlation with the Cobb angle was (r = -.37)(see Table 1). No ceiling effect was observed in the ISYQOL. Ceiling effects were observed for the SRS-22r and the SAQ. The ISYQOL demonstrated evidence of convergent validity. This study supports its suitability for QOL research in AIS. ISYQOL appears more likely to detect changes in evaluative studies than the SRS- 22r and the SAQ.
