Previous studies of the Scoliosis Research Society (SRS) 22 discriminative validity have lacked sufficiently matched study groups and were limited to a comparison with three or fewer subgroups of disease severity.
To evaluate the discriminative validity of SRS-22 by assessing the questionnaire's ability to discriminate among five groups of pretreatment adolescent idiopathic scoliosis (AIS) patients with increasing curve severity.
Retrospective review of prospectively administered surveys.
Two hundred eighty-six SRS-22 questionnaires were issued to two AIS pretreatment patient populations: 67 nonoperative and 219 preoperative. Study subjects were separated into five subgroups depending on the major Cobb angle (nonoperative 0°-19° and 20°-40° and preoperative 41°-50°, 51°-60°, and >60°). Each group (n=31) was matched for age (within 1 year) and sex (23 females and 8 males), resulting in a total of 155 study subjects. Analysis of variance was used to determine statistically significant differences (p<.05) between the five subgroups' domains and total scores.
Significant differences between study groups were found within two of the four domains (pain and image) and the total score. Both nonoperative groups (0°-19° and 20°-40°) demonstrated significantly less pain than the preoperative group (41°-50°) and significantly better self-image than all three preoperative groups. Both nonoperative groups' total scores were significantly higher than all three preoperative groups' scores, with the exception of the 20° to 40° subgroup versus the >60° subgroup. No significant differences were found between groups within the same planned treatment category.
The SRS-22 questionnaire demonstrated good discriminative validity between small nonoperative curves and larger surgical curves within the pain, image, and total domains. However, SRS-22 lacked the ability to differentiate between small intervals of curve magnitude, suggesting a limitation to the questionnaire's discriminative capacity. The discriminative validity of the Scoliosis Research Society (SRS) 22 has not been clearly defined. Our analysis of 155 adolescent idiopathic scoliosis patients evaluates the instrument's discriminative validity among five age- and sex-matched curve-severity subgroups. The SRS-22 questionnaire lacked the ability to differentiate between small intervals of curve magnitude, suggesting a limit to the questionnaire's discriminative capacity.
先前关于脊柱侧凸研究协会（SRS）22 项区分效度的研究缺乏足够匹配的研究组，并且仅限于与 3 个或更少的疾病严重程度亚组进行比较。
通过评估问卷区分 5 组青少年特发性脊柱侧凸（AIS）患者术前治疗的能力来评估 SRS-22 的区分效度，这些患者的曲线严重程度逐渐增加。
前瞻性管理调查的回顾性审查。
向两个 AIS 术前患者群体发放了 286 份 SRS-22 问卷：67 例非手术和 219 例术前。根据主要 Cobb 角（非手术 0°-19°和 20°-40°和术前 41°-50°、51°-60°和>60°），将研究对象分为五个亚组。每个组（n=31）在年龄（1 年内）和性别（23 名女性和 8 名男性）方面进行匹配，总共 155 名研究对象。方差分析用于确定五个亚组的域和总分之间的统计学显着差异（p<.05）。
在四个域（疼痛和形象）和总分中，研究组之间存在显着差异。两个非手术组（0°-19°和 20°-40°）的疼痛明显低于术前组（41°-50°），自我形象明显好于所有三个术前组。两个非手术组的总分均显着高于所有三个术前组的分数，除了 20°到 40°组与>60°组。在同一计划治疗类别内，组之间未发现显着差异。
SRS-22 问卷在疼痛，形象和总分域中，在小的非手术曲线和较大的手术曲线之间表现出良好的区分效度。然而，SRS-22 缺乏区分曲线幅度小间隔的能力，表明问卷的区分能力有限。脊柱侧凸研究协会（SRS）22 的区分效度尚未明确界定。我们对 155 例青少年特发性脊柱侧凸患者的分析评估了该工具在五个年龄和性别匹配的曲线严重程度亚组之间的区分效度。SRS-22 问卷缺乏区分曲线幅度小间隔的能力，表明问卷的区分能力有限。
