Abstract

Purpose: The Spinal Appearance Questionnaire (SAQ) is a widely validated tool for assessing perceptions of spinal deformity in adolescent idiopathic scoliosis (AIS) patients. This study aimed to develop and validate a Greek version of the SAQ (GR-SAQ).

Methods: A cross-cultural adaptation of the SAQ following international guidelines was performed. Internal consistency and test-retest reliability were evaluated. Convergent validity was assessed by correlating the GR-SAQ with the Appearance domain of Scoliosis Research Society-22 (SRS-22) and the Cobb angle with the Trunk Shift domain of GR-SAQ. Divergent validity was examined through the relationship between GR-SAQ, patient characteristics, and clinical measures including Cobb angle, DIERS Formetric 4D angle, and scoliometer readings.

Results: The study included 61 AIS patients (52 females, 13.91 ± 2.57 years, 25.33 ± 10.14° Cobb angle). GR-SAQ exhibited good internal consistency (Cronbach's α = 0.794) and excellent test-retest reliability (ICC = 0.931, 95%CI: 0.880-0.960). Correlations between GR-SAQ and SRS-22 showed a low-to-moderate negative correlation (r = -0.351, p = 0.006). The Trunk Shift domain moderately correlated with the Cobb Angle (r = 0.393, p = 0.002). Divergent validity analyses did not demonstrate statistical significance (p > 0.05).

Conclusion: The GR-SAQ is a valid and reliable tool for evaluating spinal deformity perception in Greek AIS patients.

希腊语版青少年特发性脊柱侧凸患者脊柱外观问卷（SAQ）的跨文化适应性、可靠性和有效性。

目的：脊柱外观问卷（SAQ）是一种经过广泛验证的工具，用于评估青少年特发性脊柱侧弯症（AIS）患者对脊柱畸形的看法。本研究旨在开发并验证希腊语版的SAQ（GR-SAQ）：方法：根据国际指南对 SAQ 进行了跨文化改编。评估了内部一致性和重复测试可靠性。通过将 GR-SAQ 与脊柱侧弯研究协会-22（SRS-22）的外观领域以及 Cobb 角度与 GR-SAQ 的躯干移位领域相关联，对收敛效度进行了评估。通过GR-SAQ、患者特征和临床测量（包括Cobb角、DIERS Formetric 4D角和脊柱侧弯测量仪读数）之间的关系来检验发散有效性：研究共纳入 61 名 AIS 患者（52 名女性，13.91 ± 2.57 岁，25.33 ± 10.14° Cobb 角）。GR-SAQ具有良好的内部一致性（Cronbach's α = 0.794）和出色的测试-再测可靠性（ICC = 0.931，95%CI：0.880-0.960）。GR-SAQ和SRS-22之间的相关性呈中低度负相关（r = -0.351，p = 0.006）。躯干偏移域与柯布角呈中度相关（r = 0.393，p = 0.002）。发散有效性分析未显示统计学意义（p > 0.05）：结论：GR-SAQ 是评估希腊 AIS 患者脊柱畸形感知的有效而可靠的工具。
