The Italian Spine Youth Quality of Life (ISYQOL) is a validated health-related quality of life (HRQOL) questionnaire for teenagers with adolescent idiopathic scoliosis (AIS). We culturally-adapted ISYQOL to traditional Chinese (ISYQOL-TC) and then recruited 133 conservatively treated teenagers with AIS to complete the ISYQOL-TC and the Chinese version of the Scoliosis Research Society-22 revised (SRS-22r) questionnaire, nine-item Patient Health Questionnaire (PHQ-9), seven-item Generalized Anxiety Disorder scale (GAD-7), and numeric pain rating scale (NPRS). They repeated ISYQOL-TC two weeks later. The internal consistency, unidimensionality, and test-retest reliability were measured using the Cronbach's alpha, Rasch measurement models, and intra-class correlation coefficients (ICC3,1), respectively. The concurrent validity of the ISYQOL-TC with SRS-22r, and its construct validity with other questionnaires were evaluated using Spearman correlation coefficients. The ISYQOL-TC demonstrated good internal consistency (Cronbach's alpha 0.90 and 0.89 for items 1-13 and items 1-20), and excellent test-retest reliability (ICC3,1 = 0.95-0.96). The Rasch analysis supported the unidimensionality of all 20 items in ISYQOL-TC. The ISYQOL-TC percentage scores were positively correlated with SRS-22r total scores (r = 0.65; < 0.05), but were negatively related to PHQ-9, GAD-7, and NPRS scores (r = -0.46 to -0.39; < 0.01). Collectively, the ISYQOL-TC is a reliable and valid instrument for evaluating HRQOL in Chinese teenagers with AIS.
意大利青少年脊柱生活质量问卷（ISYQOL）是一份经过验证的、用于青少年特发性脊柱侧凸（AIS）患者的健康相关生活质量（HRQOL）问卷。我们对ISYQOL进行了文化调适，使其适用于繁体中文（ISYQOL-TC），然后招募了133名接受保守治疗的AIS青少年，让他们完成ISYQOL-TC以及中文版脊柱侧弯研究学会-22修订版（SRS-22r）问卷、九项患者健康问卷（PHQ-9）、七项广泛性焦虑症量表（GAD-7）和数字疼痛评分量表（NPRS）。两周后，他们再次填写ISYQOL-TC。分别使用克朗巴哈系数、拉施测量模型和组内相关系数（ICC3,1）来测量内部一致性、单维度性和重测信度。使用斯皮尔曼相关系数评估ISYQOL-TC与SRS-22r的同时效度，以及它与其他问卷的结构效度。ISYQOL-TC显示出良好的内部一致性（第1 - 13项和第1 - 20项的克朗巴哈系数分别为0.90和0.89），以及出色的重测信度（ICC3,1 = 0.95 - 0.96）。拉施分析支持ISYQOL-TC所有20项的单维度性。ISYQOL-TC的百分比得分与SRS-22r总分呈正相关（r = 0.65；P < 0.05），但与PHQ-9、GAD-7和NPRS得分呈负相关（r = -0.46至-0.39；P < 0.01）。总体而言，ISYQOL-TC是评估中国AIS青少年HRQOL的可靠且有效的工具。
