To translate, culturally adapt, validate, and investigate the reliability of Arabic version of Bournemouth questionnaire (BQ) for patients with low back pain.
Thirty experts (three panels) and 70 low back pain patients (37.5 ± 13.9 years) were involved in this study. Test-retest as well as internal consistency analyses were used to assess reliability. Intraclass correlation coefficient (95% confidence interval) was used to assess test-retest analysis, whereas Cronbach alpha value was calculated to assess the internal consistency. BQ Arabic version validity was evaluated in forms of face, content, internal, and external construct validity. Internal construct validity was evaluated with factor analysis, and external construct validity was tested by the correlation between the Arabic version of BQ and short-form (36) health survey (SF-36) questionnaire.
Factor analysis revealed that BQ had a single factor. BQ has a very good correlation with SF-36 questionnaire (r = .74). Arabic version of BQ has a high internal consistency reliability where Cronbach alpha value was 0.889 at baseline and 0.911 after 1 week. The test-retest analysis was between 0.87 and 0.96 and for the BQ total score was 0.95 (p < .0001) indicating that test-retest results are highly correlated.
The Arabic version of BQ is a valid, reliable, and feasible scale for assessment of low back patients. It is short, easy-to-apply, need short time to complete and comprehensive scale. So it may be considered as a preferable scale for clinical assessment of Arabic speaking patients with low back pain.
翻译、文化调适、验证并研究腰痛患者简体中文版伯恩茅斯问卷（BQ）的信度。
本研究纳入了 30 名专家（分为三组）和 70 名腰痛患者（37.5±13.9 岁）。采用重测信度和内部一致性分析来评估可靠性。采用组内相关系数（95%置信区间）评估重测分析，采用 Cronbach α 值评估内部一致性。BQ 阿拉伯文版本的有效性通过表面效度、内容效度、内部结构效度和外部结构效度进行评估。内部结构效度通过因子分析进行评估，外部结构效度通过 BQ 阿拉伯文版与简短健康调查 36 项问卷（SF-36）之间的相关性进行测试。
因子分析显示 BQ 具有单一因素。BQ 与 SF-36 问卷具有非常高的相关性（r=.74）。BQ 阿拉伯文版具有很高的内部一致性信度，基线时 Cronbach α 值为 0.889，1 周后为 0.911。重测分析在 0.87 到 0.96 之间，BQ 总分的重测信度为 0.95（p<.0001），表明重测结果相关性较高。
BQ 阿拉伯文版是一种评估腰痛患者的有效、可靠和可行的量表。它简短、易于应用、完成时间短、内容全面。因此，它可以被认为是评估阿拉伯语腰痛患者的一种首选量表。
