研究设计.确定脊柱侧凸研究协会-22（SRS-22）健康相关生活质量（HRQL）量表的反应分布、内部一致性、重复性和同时有效性的结果研究。特发性脊柱侧凸HRQL问卷的进一步完善。背景资料总结。以前的经验与原始和修改SRS HRQL问卷建议需要进一步完善和更完整的验证。将SRS-22和简明健康状况调查问卷（SF-36）邮寄给83名既往接受调查的术后特发性脊柱侧凸患者。58名（70%）患者返回了第一组问卷。他们手术时的平均年龄为14.6岁，手术后的平均随访时间为10.8年。58人中有51人（88%）在平均28天后返回了第二组问卷。工具的心理测量属性具有可比性：分数分布，SRS-22 56.9%上限和1.7%下限，SF-36 79.3%上限和1.7%下限;内部一致性（Cronbach α），SRS-22 0.92 ~ 0.75，SF-36 0.91 ~ 0.36;和重现性（组内相关系数），SRS-22 0.96至0.85，SF-36 0.92至0.61。SRS-22和SF-36领域的Pearson相关系数测定的同时效度为0.70或更高（P
Study Design. Outcome study to determine response distribution, internal consistency, reproducibility, and concurrent validity of the Scoliosis Research Society-22 (SRS-22) health-related quality-of-life (HRQL) questionnaire.Objectives. Further refinement of an HRQL questionnaire specific for idiopathic scoliosis.Summary of Background Data. Previous experience with the original and modified SRS HRQL questionnaires suggested a need for further refinement and more complete validation.Methods. The SRS-22 and Short Form 36 (SF-36) HRQL questionnaires were mailed to 83 previously surveyed postoperative idiopathic scoliosis patients.Results. Fifty-eight (70%) patients returned the first set of questionnaires. Their average age at surgery was 14.6 years, and their average follow-up interval since surgery was 10.8 years. Fifty-one (88%) of the 58 returned the second set of questionnaires an average of 28 days later. The psychometric attributes of the instruments were comparable: score distribution, SRS-22 56.9% ceiling and 1.7% floor, SF-36 79.3% ceiling and 1.7% floor; internal consistency (Cronbach alpha), SRS-22 0.92 to 0.75, SF-36 0.91 to 0.36; and reproducibility (intraclass correlation coefficient), SRS-22 0.96 to 0.85, SF-36 0.92 to 0.61. Concurrent validity, determined by Pearson Correlation Coefficients between SRS-22 and SF-36 domains, was 0.70 or greater (P
