Earlier scales on mindful eating do not measure mindful eating independent from emotional or external eating, or mindful eating in common situations.
The objective was to develop a new instrument to measure the attention element of mindful eating, the Mindful Eating Behavior Scale (MEBS), and to compute the internal structure, reliabilities, and convergent validity of this scale.
A cross-sectional ancillary study within the Longitudinal Aging Study Amsterdam was conducted between fall 2014 and spring 2015.
PARTICIPANTS/SETTING: Participants were 1,227 Dutch adults aged 55 years and older from the Longitudinal Aging Study Amsterdam.
A selection of 20 items from existing instruments was used to design an initial version of the MEBS.
The internal structure of the MEBS was evaluated using an exploratory structural equation modeling approach on half of the sample and confirmatory factor analysis on the whole sample to develop the final version of the scale. The measurement invariance of the scores was tested with respect to sex, age, and body mass index. Reliabilities of subscales were determined with Cronbach's α. To test convergent validity, the scores of the new scale were correlated with theoretically relevant variables.
Two items were deleted because of low item loadings and one item because of high correlated uniqueness. The final confirmatory factor analysis model with 17 items and four domains (Focused Eating, Hunger and Satiety Cues, Eating with Awareness, and Eating without Distraction) showed good fit (comparative fit index=0.97, Tucker-Lewis index=0.96, and root mean square error of approximation=0.04). Measurement invariance was found for sex, age, and body mass index. Cronbach's α values were medium to high (.70 to .89). Most correlations were in the expected directions, which indicated good preliminary convergent validity.
The MEBS was successfully developed consisting of 17 items and four domains. Because of low interfactor correlations, a total score combining the four domains should not be computed. The MEBS showed good internal consistency and preliminary convergent validity in a sample of Dutch adults aged 55 years and older.
早期的正念饮食量表不能将正念饮食与情绪或外部饮食分开进行测量，也不能在常见情况下进行测量。
旨在开发一种新的量表来测量正念饮食的注意力元素，即正念饮食行为量表（MEBS），并计算该量表的内部结构、信度和收敛效度。
这是一项在阿姆斯特丹纵向老龄化研究中进行的横断面辅助研究，时间为 2014 年秋季至 2015 年春季。
参与者/设置：参与者为来自阿姆斯特丹纵向老龄化研究的 1227 名 55 岁及以上的荷兰成年人。
从现有工具中选择 20 个项目来设计 MEBS 的初始版本。
使用半样本进行探索性结构方程建模方法评估 MEBS 的内部结构，并对整个样本进行验证性因素分析，以开发量表的最终版本。测试了分数的测量不变性，以性别、年龄和体重指数为参照。使用 Cronbach 的 α 确定子量表的可靠性。为了检验收敛效度，将新量表的分数与理论上相关的变量进行了相关分析。
由于项目负荷低，删除了 2 个项目，由于相关独特性高，删除了 1 个项目。最终的验证性因素分析模型包含 17 个项目和 4 个领域（专注进食、饥饿和饱腹感提示、有意识进食和无干扰进食），具有良好的拟合度（比较拟合指数=0.97，Tucker-Lewis 指数=0.96，均方根误差近似值=0.04）。发现性别、年龄和体重指数的测量不变性。Cronbach 的 α 值为中等至较高（0.70 至 0.89）。大多数相关性均在预期方向，表明具有良好的初步收敛效度。
成功开发了由 17 个项目和 4 个领域组成的 MEBS。由于因子间相关性较低，不应计算四个领域的总分。在 55 岁及以上的荷兰成年人样本中，MEBS 显示出良好的内部一致性和初步收敛效度。
