Adolescent idiopathic scoliosis (AIS) is among the most common spinal deformities affecting adolescents. The Scoliosis Research Society-22 questionnaire is commonly used to assess health-related quality of life in AIS patients, including pain. The objective of this study is to verify the psychometric properties of the Scoliosis Research Society-22 French version (SRS-22fv) questionnaire.
A prospective methodological design was used to verify the psychometric properties of the French version of the SRS-22fv. Participants were initially recruited from the orthopaedic scoliosis department at Sainte-Justine Hospital (Montreal, Canada) and completed the SRS-22fv and the SF-12 questionnaire. The SRS-22fv's structure was evaluated through principal component analysis (PCA). Linear regression was used to assess convergent validity between the SRS-22fv and the SF-12.
Data was available from 352 participants with AIS. Most participants were female (87%, = 307), and the average age was 14.3 (SD = 1.8) years. The mean thoracic and lumbar Cobb angles were 27.9° (SD = 3.3) and 23.6° (SD = 9.4), respectively. Overall, 71.4% ( = 252) of the participants presented with spinal pain. About one-third (29%) reported thoracic pain, and almost half (44%) experienced lumbar pain. The PCA identified four redundant items, which resulted in a modified 18-item questionnaire. In comparison to the original questionnaire, the modified version showed higher levels of internal consistency for four of the five factors, explained a greater proportion of the total variance (63.3%), and generated higher inter-item total correlations.
We propose a shorter version of the SRS-22fv, thus the Canadian SRS-18fv, which showed an improved internal consistency and scale structure compared to the original SRS-22fv. We believe that this modified version would be better suited to assess the quality of life of adolescents with idiopathic scoliosis.
青少年特发性脊柱侧凸（AIS）是影响青少年的最常见脊柱畸形之一。脊柱侧凸研究学会-22问卷常用于评估AIS患者与健康相关的生活质量，包括疼痛情况。本研究的目的是验证脊柱侧凸研究学会-22法语版（SRS-22fv）问卷的心理测量特性。
采用前瞻性方法设计来验证SRS-22fv法语版的心理测量特性。参与者最初从圣朱斯坦医院（加拿大蒙特利尔）的骨科脊柱侧弯科招募，并完成SRS-22fv和SF-12问卷。通过主成分分析（PCA）评估SRS-22fv的结构。使用线性回归评估SRS-22fv与SF-12之间的收敛效度。
获得了352名AIS参与者的数据。大多数参与者为女性（87%，n = 307），平均年龄为14.3岁（标准差 = 1.8）。胸段和腰段Cobb角的平均值分别为27.9°（标准差 = 3.3）和23.6°（标准差 = 9.4）。总体而言，71.4%（n = 252）的参与者存在脊柱疼痛。约三分之一（29%）报告有胸段疼痛，近一半（44%）经历过腰段疼痛。主成分分析确定了四个冗余项目，从而形成了一个修改后的18项问卷。与原始问卷相比，修改后的版本在五个因素中的四个因素上显示出更高的内部一致性，解释了总方差的更大比例（63.3%），并产生了更高的项目间总相关性。
我们提出了一个更简短的SRS-22fv版本，即加拿大SRS-18fv，与原始的SRS-22fv相比，它显示出更好的内部一致性和量表结构。我们认为这个修改后的版本更适合评估青少年特发性脊柱侧凸患者的生活质量。
