背景技术背景：青少年特发性脊柱侧凸患者的外观问题可能导致日常功能障碍或身体形象障碍。体像障碍问卷（BIDQ）是一种自我报告的七个问题的工具，用于测量一般人群的体像障碍;没有研究专门研究青少年特发性脊柱侧凸患者的体像障碍。本研究旨在验证青少年特发性脊柱侧凸人群中BIDQ的修改版本，并通过比较手术和非手术治疗患者与正常对照组的反应来建立判别效度。（平均年龄，14岁; 37名女性）患有青少年特发性脊柱侧凸，以验证BIDQ-脊柱侧凸版本（BIDQ-S）。参与者完成了BIDQ-S、脊柱侧凸研究协会（SRS）-22、儿童抑郁指数（CDI）和青少年和成人身体自尊量表（BESAA）问卷。计算描述性统计量和Pearson相关系数。在第二阶段，98例青少年特发性脊柱侧凸患者（平均年龄15.7岁; 75名女性）与98名健康青少年在年龄和性别上相匹配，被纳入一项单中心研究，以评估BIDQ-S的判别效度。受试者在治疗前填写BIDQ-S和人口统计表。独立样本t检验和Pearson相关系数进行了计算。结果：BIDQ-S是内部一致的（Cronbach α = 0.82），校正项目总相关系数范围为0.47至0.67。BIDQ-S与SRS-22的每个领域和总分（r = -0.50至-0.72，p ≤ 0.001）、CDI（r = 0.31，p = 0.03）和BESAA（r = 0.60，p < 0.001）显著相关。BIDQ-S评分在患者（1.50）和对照组（1.06，p < 0.005）之间差异显著，建立了判别validity.CONCLUSIONS：在脊柱侧凸人群中，BIDQ-S是一种与SRS-22、CDI和BESAA结果工具相关的内部一致性结果工具。与健康对照组相比，脊柱侧凸患者的评分显示更大的背部相关的身体形象障碍。据我们所知，这种用户友好的工具是第一个检查青少年特发性脊柱侧凸的身体形象障碍，它提供了一个全面的评估脊柱侧凸相关的外观问题如何影响社会心理和日常功能。
BACKGROUND: Appearance concerns in individuals with adolescent idiopathic scoliosis can result in impairment in daily functioning, or body image disturbance. The Body Image Disturbance Questionnaire (BIDQ) is a self-reported, seven-question instrument that measures body image disturbance in general populations; no studies have specifically examined body image disturbance in those with adolescent idiopathic scoliosis. This study aimed to validate a modified version of the BIDQ in a population with adolescent idiopathic scoliosis and to establish discriminant validity by comparing responses of operatively and nonoperatively treated patients with those of normal controls.METHODS: In the first phase, a multicenter study of forty-nine patients (mean age, fourteen years; thirty-seven female) with adolescent idiopathic scoliosis was performed to validate the BIDQ-Scoliosis version (BIDQ-S). Participants completed the BIDQ-S, Scoliosis Research Society (SRS)-22, Children's Depression Index (CDI), and Body Esteem Scale for Adolescents and Adults (BESAA) questionnaires. Descriptive statistics and Pearson correlation coefficients were calculated. In the second phase, ninety-eight patients with adolescent idiopathic scoliosis (mean age, 15.7 years; seventy-five female) matched by age and sex with ninety-eight healthy adolescents were enrolled into a single-center study to evaluate the discriminant validity of the BIDQ-S. Subjects completed the BIDQ-S and a demographic form before treatment. Independent-sample t tests and Pearson correlation coefficients were calculated.RESULTS: The BIDQ-S was internally consistent (Cronbach alpha = 0.82), and corrected item total correlations ranged from 0.47 to 0.67. The BIDQ-S was significantly correlated with each domain of the SRS-22 and the total score (r = -0.50 to -0.72, p ≤ 0.001), with the CDI (r = 0.31, p = 0.03), and with the BESAA (r = 0.60, p < 0.001). BIDQ-S scores differed significantly between patients (1.50) and controls (1.06, p < 0.005), establishing discriminant validity.CONCLUSIONS: The BIDQ-S is an internally consistent outcomes instrument that correlated with the SRS-22, CDI, and BESAA outcomes instruments in a scoliosis population. The scores of the patients with scoliosis indicated greater back-related body image disturbance compared with healthy controls. To our knowledge, this user-friendly instrument is the first to examine body image disturbance in adolescent idiopathic scoliosis, and it provides a comprehensive evaluation of how scoliosis-related appearance concerns impact psychosocial and daily functioning.
