Abstract

BACKGROUND

There are relatively few data about the association between locus of control and weight loss in Arabic populations. A tool does exist, the Dieting Belief Scale (DBS), that was designed to measure individuals' beliefs regarding their ability to control their body weight. The aim of this study was to translate this tool into Arabic and to evaluate its psychometric properties.

METHODS

The forward translation of the DBS from English to Arabic was completed by two professional bilingual translators, while the back translation from Arabic to English was independently performed by another two different professional bilingual translators. An online survey using the tool was then completed by 245 participants, fully aware of the study's purpose. Psychometric analyses were subsequently conducted to assess the reliability and validity of the Arabic DBS.Internal consistency was examined using Cronbach's α and McDonald's ω coefficients. Test-retest reliability was also assessed. Confirmatory factor analysis was employed to evaluate the fit of a three-factor model, with indices including Comparative Fit Index (CFI), Tucker Lewis Index (TLI), Root Mean Square Error of Approximation (RMSEA), and Standardized Root Mean Square Residual (SRMR). Convergent validity was assessed by examining the correlation between the Arabic DBS and the Eating Attitude Test (EAT-26) previously translated into Arabic, the latter identifying attitudes, feelings and behaviors related to eating.

RESULTS

The Arabic translated DBS scale demonstrated high translation accuracy and content validity estimates. Cronbach's α and McDonald's ω reliability coefficients for the translated scale were approximately 0.91. Test-retest reliability was 0.96. The three-factor model showed an acceptable fit (CFI = 0.93, TLI = 0.92, RMSE = 0.08, SRMR = 0.06). The Arabic version of the DBS was found to have good convergent validity, as evidenced by the significant correlation between the EAT-26 and DBS questionnaires ( = 0.53, p < 0.01).

CONCLUSION

The Arabic version of the DBS is highly reliable and has sufficient content validity to measure belief about personal ability to control one's weight.

摘要

背景

关于阿拉伯人群中控制点与体重减轻之间关联的数据相对较少。确实存在一种工具，即节食信念量表（DBS），其设计目的是测量个体对自身控制体重能力的信念。本研究的目的是将该工具翻译成阿拉伯语并评估其心理测量特性。

方法

DBS从英语到阿拉伯语的正向翻译由两位专业双语翻译完成，而从阿拉伯语到英语的反向翻译则由另外两位不同的专业双语翻译独立进行。然后，245名完全知晓研究目的的参与者完成了使用该工具的在线调查。随后进行了心理测量分析，以评估阿拉伯语DBS的信度和效度。使用克朗巴哈α系数和麦克唐纳ω系数检验内部一致性。还评估了重测信度。采用验证性因素分析来评估三因素模型的拟合度，指标包括比较拟合指数（CFI）、塔克·刘易斯指数（TLI）、近似均方根误差（RMSEA）和标准化均方根残差（SRMR）。通过检查阿拉伯语DBS与先前翻译成阿拉伯语的饮食态度测试（EAT - 26）之间的相关性来评估收敛效度，后者用于识别与饮食相关的态度、感受和行为。

结果

阿拉伯语翻译的DBS量表显示出较高的翻译准确性和内容效度估计值。翻译后量表的克朗巴哈α系数和麦克唐纳ω信度系数约为0.91。重测信度为0.96。三因素模型显示出可接受的拟合度（CFI = 0.93，TLI = 0.92，RMSE = 0.08，SRMR = 0.06）。DBS的阿拉伯语版本具有良好的收敛效度，EAT - 26问卷与DBS问卷之间的显著相关性证明了这一点（= 0.53，p < 0.01）。
