Outcome study to determine response distribution, internal consistency, and validity of a Modified SRS Outcomes Instrument (MSRSI).
Refinement and validation of the SRS Outcomes Instrument for idiopathic scoliosis.
Experience with the SRS Outcomes Instrument suggested several refinements and the need for validation.
Following experience-based modification, the Modified SRS Outcomes Instrument and Short Form 36 (SF-36) questionnaires were administered to 35 previously surveyed postoperative idiopathic scoliosis patients.
Thirty (86%) patients with an average age of 25 years returned the questionnaires at an average of 10 years postoperative. Distribution of scores was acceptable. Internal consistency utilizing Cronbach's alpha was 0.80, 0.81, 0.77, 0.89, and 0.88 for pain, self-image/appearance, function/activity, mental health, and satisfaction with surgery, respectively. Validity, determined by Pearson correlation coefficients with comparable SF-36 domains, was 0.70 or greater for 13 of the 14 relevant domains between SF-36 and MSRSI (P < 0.001).
The SRS Outcomes Instrument is simple and internally consistent. Based on experience, a number of modifications have been made that improve the instruments scope and internal consistency. Finally, the instrument is valid in comparison to SF-36.
一项结果研究，以确定改良的脊柱侧凸研究学会（SRS）结果量表（MSRSI）的反应分布、内部一致性和有效性。
完善并验证用于特发性脊柱侧凸的SRS结果量表。
使用SRS结果量表的经验提示了一些改进之处以及验证的必要性。
在基于经验进行修改后，向35名之前接受过调查的特发性脊柱侧凸术后患者发放改良的SRS结果量表问卷和简短健康调查问卷（SF-36）。
30名（86%）平均年龄25岁的患者在术后平均10年时返还了问卷。分数分布可接受。疼痛、自我形象/外观、功能/活动、心理健康以及对手术的满意度这几个方面利用克朗巴哈系数得出的内部一致性分别为0.80、0.81、0.77、0.89和0.88。通过与SF-36相应领域的皮尔逊相关系数确定的有效性方面，SF-36与MSRSI之间14个相关领域中的13个领域的相关系数为0.70或更高（P < 0.001）。
SRS结果量表简单且内部一致。基于经验进行了多项改进，这些改进扩大了该量表的范围并提高了其内部一致性。最后，与SF-36相比，该量表是有效的。
