摘　　要：目的建立简体中文版脊柱外观问卷(spinal appearance questionnaire,SAQ)并测验其用于评价青少年特发性脊柱侧凸患者外观的信度和效度。方法根据国际标准化指南对英文版SAQ问卷进行翻译和文化调适后建立简体中文版SAQ。共纳入95例青少年特发性脊柱侧凸患者完成简体中文版SAQ问卷与SRS-22问卷,随机选取50例患者间隔7 d完成第二次简体中文版SAQ问卷并计算组内相关系数(intraclass coefficient correlation,ICC)、Bland-Alt-man一致性以评价重测信度。对95例患者各维度内的条目得分进行Spearman相关分析评价维度内一致性;对SAQ总分与SRS-22外观维度得分进行Pearson相关分析完成聚合效度评价,通过对SAQ总分与最大Cobb角的Pearson相关分析,以及不同角度组、不同治疗组间的SAQ总分差异的方差分析完成区分效度评价。结果 SAQ各条目间一致性系数范围为0.521～0.792(P<0.01),重测ICC为0.965,Bland-Altman一致性测验显示良好的测量一致性。聚合效度分析提示SAQ总分与SRS-22外观维度的相关系数为r=-0.326(P<0.01);区分效度分析提示SAQ总分与最大Cobb角的相关系数为0.779(P<0.01),SAQ总分在不同最大Cobb角亚组间、不同推荐治疗组间差异有统计学意义(P<0.01)。结论简体中文版SAQ对于测量中国青少年特发性脊柱侧凸患者外观具有良好的信度与效度。Objective To develop a simplified Chinese version of spinal appearance questionnaire（SAQ） and assess its reliability and validity among patients with adolescent idiopathic scoliosis（AIS）.Methods The SAQ was translated and cross-culturally adapted into simplified Chinese according the international guideline.A total of 95 AIS patients were recruited to finish the simplified Chinese SAQ and SRS-22.In order to assess the test-retest reliability,50 AIS patients were randomly selected to re-complete the SAQ at a time interval of 7 d.Internal consistency coefficient（ICC） was calculated and the Bland-Altman plot was made.Convergent validity was assessed by Pearson correlation analysis between the simplified Chinese SAQ with the simplified chinese SRS-22 appearance domain,and discriminant validity by analyzing the relationship between simplified Chinese SAQ scores and the severity of deformity and different scheduled treatments.Results Internal consistency for the SAQ was satisfactory with intra-domain correlation coefficients ranging 0.521-0.792（P0.01）.The test-retest reliability for the SAQ was excellent with intra-class correlation coefficient being 0.965 and good Bland-Altman agreement.Convergent validity test demonstrated a moderate correlation between the overall SAQ and SRS-22 appearance domain with r=-0.326（P0.01）.Correlation between the overall SAQ and the major Cobb＇s angle was significant with r =0.779（P0.01）.Discriminant validity was confirmed by significant differences of SAQ total scores among the 3 subgroups categorized by the major Cobb＇s angle（P0.001） and among patients who required exercise,bracing,or surgery（P0.01）.Conclusion Our simplified Chinese SAQ has satisfactory reliability and validity in evaluating spinal deformity appearance in Chinese AIS.
