Cross-sectional mail questionnaire.
Assess the feasibility of translating total and domain scores from Scoliosis Research Society (SRS)-24, SRS-23, and SRS-22 to SRS-22r.
Three successive editions of the original SRS-24 health-related quality-of-life questionnaire have resulted from efforts to improve its psychometric properties and validate its use in patients down to 10 years of age. This resulted in the need to establish, if possible, conversion equations to the last and most thoroughly validated version, SRS-22r.
A consolidated questionnaire of 49 questions that incorporated the various questions in the four questionnaires was mailed to a consecutive series of 235 patients who had received primary posterior or anterior instrumentation and arthrodesis to treat adolescent idiopathic scoliosis. Regression modeling was used to establish conversion equations from the SRS-24, SRS-23, and SRS-22 to the SRS-22r.
One hundred twenty-one of the 235 patients (51%), aged 23.3 ± 4.52 years (range 14.2-34.6 years), returned the questionnaire at 8.6 ± 4.00 years (range 2.3-15.9 years) following surgery. Estimation of SRS-22r questionnaire and nonmanagement domains total scores and mean scores from SRS-22 and SRS-23 scores is excellent (R2 scores of 0.97-0.99) and good for SRS-24 scores (R2 scores of 0.80-0.82, improving to 0.86 and 0.87 after minimal domain reconfiguration). Estimation of SRS-22r individual domain total scores and mean scores from SRS-22 and SRS-23 is good to excellent (R2 scores of 0.81-0.99). Minimal domain reconfiguration improves conversion from SRS-24 pain from R2 = 0.71 to 0.76, which are both fair; SRS-24 function from R2 = 0.69 and 0.74 to 0.83, from poor and fair to good; and SRS-24 satisfaction/dissatisfaction with management from R2 = 0.64 to 0.80, from poor to good. Conversion of SRS-24 self-image is poor (R2 = 0.60) despite the correlation being statistically significant.
With one exception, SRS-24, SRS-23, and SRS-22 questionnaire, nonmanagement domains, and individual domain total scores and mean scores can be translated to SRS-22r scores with fair to excellent accuracy, which is further improved in some instances by minimal domain reconfigurations. The sole exception is SRS-24 self-image, which translates poorly.
横断面邮件问卷调查。
评估将 Scoliosis Research Society（SRS）-24、SRS-23 和 SRS-22 的总分和领域评分转换为 SRS-22r 的可行性。
为了提高原始 SRS-24 健康相关生活质量问卷的心理测量特性并验证其在 10 岁以下患者中的使用，已经进行了三次连续的 SRS-24 版本更新。这导致需要建立，如果可能的话，到最新且经过最彻底验证的版本 SRS-22r 的转换方程。
将包含四个问卷中各种问题的 49 个问题的综合问卷邮寄给连续的 235 名患者，这些患者接受了后路或前路器械和融合术治疗青少年特发性脊柱侧凸。回归建模用于建立从 SRS-24、SRS-23 和 SRS-22 到 SRS-22r 的转换方程。
在手术后 8.6±4.00 年（范围 2.3-15.9 年），235 名患者中有 121 名（51%）返回了问卷，他们的年龄为 23.3±4.52 岁（范围 14.2-34.6 岁）。从 SRS-22 和 SRS-23 分数估计 SRS-22r 问卷和非管理领域总分和平均分数非常好（R2 分数为 0.97-0.99），对于 SRS-24 分数也很好（R2 分数为 0.80-0.82，经过最小的域重构后提高到 0.86 和 0.87）。从 SRS-22 和 SRS-23 估计 SRS-22r 各领域总分和平均分数为良好至优秀（R2 分数为 0.81-0.99）。最小的域重构可改善 SRS-24 疼痛的转换，从 R2=0.71 提高到 0.76，均为中等；SRS-24 功能从 R2=0.69 和 0.74 提高到 0.83，从差和中等提高到良好；SRS-24 对管理的满意度/不满意从 R2=0.64 提高到 0.80，从差提高到良好。尽管相关性具有统计学意义，但 SRS-24 自我形象的转换很差（R2=0.60）。
除了一个例外 SRS-24，SRS-23 和 SRS-22 问卷、非管理领域以及各领域总分和平均分数都可以转换为 SRS-22r 分数，其准确性为中等至优秀，在某些情况下通过最小的域重构可以进一步提高。唯一的例外是 SRS-24 自我形象，其转换效果不佳。
