To assess the psychometric properties of the Mindful Eating Questionnaire (MEQ).
A total of 15 mindfulness experts evaluated the content of the 28 items and 5 factors of the MEQ. A sample of 1,067 Italian adults (61.4% women) completed the MEQ and other measures; 62 participants completed a 4-week test-retest.
Content analysis reduced the MEQ to 20 items. Exploratory and confirmatory factor analyses supported a 2-factor model based on awareness and recognition of hunger and satiety cues. Factors showed adequate internal consistency (α = .75 and .83, respectively) and test-retest reliability (intraclass correlation coefficient = 0.73 and 0.85, respectively), and were associated in expected ways, although with small to moderate effect sizes, with general mindfulness, meditation experience, yoga practice, not being on a diet plan, and body mass index categories.
Findings provided evidence of validity and reliability for the 20-item MEQ and support its use by clinicians and researchers for addressing eating-related issues.
评估正念饮食问卷(MEQ)的心理测量特性。
共有15位正念专家对MEQ的28个项目和5个因子的内容进行了评估。1067名意大利成年人(61.4%为女性)的样本完成了MEQ及其他测量;62名参与者完成了为期4周的重测。
内容分析将MEQ缩减至20个项目。探索性和验证性因子分析支持了基于对饥饿和饱腹感线索的意识与识别的两因子模型。各因子显示出足够的内部一致性(分别为α = 0.75和0.83)和重测信度(组内相关系数分别为0.73和0.85),并且以预期的方式与一般正念、冥想经验、瑜伽练习、未遵循饮食计划以及体重指数类别相关,尽管效应大小为小到中等。
研究结果为20项MEQ的有效性和可靠性提供了证据,并支持临床医生和研究人员使用该问卷来解决与饮食相关的问题。
