The 9-item Body Dissatisfaction Subscale (BDS) of the Eating Disorder Inventory is one of the most used tools for assessing thinness-oriented body dissatisfaction in research and clinical practice. However, no validated Arabic version of this scale exists to date. In this study, we sought to validate this instrument in three samples of native Arabic-speaking adolescents, adults, and pregnant women from Lebanon.
A total of 826 adults, 555 adolescents, and 433 pregnant women were included. To examine the factor structure of the BDS, we performed an exploratory factor analysis (EFA), using a principal component analysis via the FACTOR software on the first split-half subsample among Lebanese adults. We used data from the second split-half in the adult sample to conduct a Confirmatory Factor Analysis (CFA) through the SPSS AMOS v.29 software. That verified model was tested via CFA on adolescents and pregnant women.
The EFA showed a bidimensional structure for the BDS, with all 9 items retained and divided into Factor 1 = Body Satisfaction (negatively-worded items) and Factor 2 = Body Dissatisfaction (positively-worded items). The CFA demonstrated invariable goodness-of-fit of the instrument in the three studied populations. McDonald's omega values were also adequate in the three samples, demonstrating its reliability. Moreover, the BDS showed invariance across sex among both adolescents and adults. Finally, higher BDS scores were correlated with more disordered eating, less body appreciation and less functionality appreciation, thus attesting to convergent validity of the scale. In addition, BDS scores correlated positively with depression and anxiety scores, indicating adequate patterns of divergent validity.
In light of our findings, we endorse the use of the BDS by healthcare professionals in Arabic-speaking countries, in order to assess thinness-oriented body dissatisfaction in an appropriate and timely manner and ease early referral to a specialist, thereby preventing the deleterious health-related risks associated with this condition.
《饮食失调量表》中的9项身体不满分量表（BDS）是研究和临床实践中评估以瘦为导向的身体不满最常用的工具之一。然而，迄今为止，该量表尚无经过验证的阿拉伯语版本。在本研究中，我们试图在来自黎巴嫩的以阿拉伯语为母语的青少年、成年人和孕妇的三个样本中验证该工具。
共纳入826名成年人、555名青少年和433名孕妇。为了检验BDS的因子结构，我们进行了探索性因子分析（EFA），通过FACTOR软件对黎巴嫩成年人的第一个对半子样本进行主成分分析。我们使用成人样本中第二个对半子样本的数据，通过SPSS AMOS v.29软件进行验证性因子分析（CFA）。通过CFA在青少年和孕妇中对该验证模型进行测试。
EFA显示BDS具有二维结构，所有9个项目均保留，并分为因子1 =身体满意度（反向计分项目）和因子2 =身体不满（正向计分项目）。CFA表明该工具在三个研究人群中具有不变的拟合优度。麦克唐纳ω值在三个样本中也足够，证明了其可靠性。此外，BDS在青少年和成年人中均显示出性别不变性。最后，较高的BDS得分与更多的饮食失调、更少的身体欣赏和更少的功能欣赏相关，从而证明了该量表的收敛效度。此外，BDS得分与抑郁和焦虑得分呈正相关，表明具有适当的区分效度模式。
根据我们的研究结果，我们支持阿拉伯语国家的医疗保健专业人员使用BDS，以便以适当和及时的方式评估以瘦为导向的身体不满，并便于早期转诊至专科医生，从而预防与这种情况相关的有害健康风险。
