Cross-cultural adaptation and validation of the Body Image Disturbance Questionnaire-Scoliosis OBJECTIVE.: The purpose of this study was to evaluate the reliability and validity of an adapted Korean version of the Body Image Disturbance Questionnaire-Scoliosis version (BIDQ-S).
A modified version of the BIDQ instrument has been validated in adolescent idiopathic scoliosis (AIS) to assess the perception of spinal appearance and psychological disturbance. However, there is no culturally adapted, reliable, and validated BIDQ-S for the Korean population.
Translation/retranslation of the English version of the BIDQ-S was conducted, and all steps of the cross-cultural adaptation process were performed. The Korean version of the BIDQ-S (K-BIDQ-S) and the previously validated appearance domain of the Korean version of the Scoliosis Research Society-22 Outcomes questionnaire (K-SRS-22) and Spinal Appearance Questionnaire (K-SAQ) were mailed to 152 patients with AIS. Reliability assessments were conducted using κ statistics to assess item agreements, and intraclass correlation coefficients (ICCs) and Cronbach α values were calculated. Convergent validity was evaluated by comparing the scores of the K-BIDQ-S, K-SAQ, and K-SRS-22 appearance domain and discriminant validity by analyzing relationships between K-BIDQ-S score and patient characteristics.
All items of the K-BIDQ-S had κ values of agreement >0.6. The K-BIDQ-S showed excellent test/retest reliability with an ICC of 0.912. Internal consistency of the K-BIDQ-S was found to be very good (α = 0.880). Convergent validity testing demonstrated good correlations between the K-BIDQ-S and K-SAQ (r = 0.617), and between the K-BIDQ-S and K-SRS-22 (r = -651). The correlation between the K-BIDQ-S and major curve magnitude was significant (r = 0.688). Discriminant validity was confirmed by significant differences in K-BIDQ-S scores among patients requiring observation, bracing, or surgery.
The K-BIDQ-S showed satisfactory reliability and validity, and thus, is considered suitable for the evaluation of spinal deformity appearance in Korean-speaking patients with AIS.
脊柱侧凸体像障碍问卷的跨文化适应性和验证目的：本研究旨在评估经改良的韩国版体像障碍问卷-脊柱侧凸版（BIDQ-S）的可靠性和有效性。
一种改良版的 BIDQ 工具已在青少年特发性脊柱侧凸（AIS）中得到验证，用于评估脊柱外观和心理障碍的感知。然而，目前还没有针对韩国人群的文化适应性强、可靠且经过验证的 BIDQ-S。
对 BIDQ-S 的英文版本进行翻译/重新翻译，并进行了跨文化适应过程的所有步骤。将 BIDQ-S 的韩国版（K-BIDQ-S）以及先前经过验证的韩国版 Scoliosis Research Society-22 结果问卷（K-SRS-22）的外观域和 Spinal Appearance Questionnaire（K-SAQ）寄给 152 名 AIS 患者。使用κ统计评估可靠性，以评估项目一致性，计算组内相关系数（ICC）和 Cronbach α 值。通过比较 K-BIDQ-S、K-SAQ 和 K-SRS-22 外观域的得分来评估聚合效度，并通过分析 K-BIDQ-S 得分与患者特征之间的关系来评估判别效度。
K-BIDQ-S 的所有项目的一致性κ值均>0.6。K-BIDQ-S 具有极好的测试/重测可靠性，ICC 为 0.912。K-BIDQ-S 的内部一致性被发现非常好（α=0.880）。聚合效度测试表明 K-BIDQ-S 与 K-SAQ 之间存在良好的相关性（r=0.617），以及 K-BIDQ-S 与 K-SRS-22 之间的相关性（r=-0.651）。K-BIDQ-S 与主曲线幅度之间的相关性显著（r=0.688）。通过 K-BIDQ-S 评分在需要观察、支具或手术的患者之间的显著差异，确认了判别效度。
K-BIDQ-S 显示出令人满意的可靠性和有效性，因此，被认为适合评估讲韩语的 AIS 患者的脊柱畸形外观。
