Food addiction is increasingly being recognised as a contributory factor in overweight and obesity. Management of eating compulsivity, a key component of food addiction, may assist greatly in the successful treatment of obesity. Measurement of food addiction and its core characteristic of eating compulsivity is fundamental to increasing understandings of the concept of food addiction, its prevalence among people with and without obesity and its utility within a treatment context. The current study describes the development and initial validation of a brief measure of eating compulsivity that can be used within clinical and research settings to establish a person's level of eating compulsivity. Sixty five participants with a BMI ≥30 (mean BMI 38.1) were recruited from a general population sample within Christchurch, New Zealand. Participants completed the test version of the Measure of Eating Compulsivity (MEC) and the Yale Food Addiction Scale (YFAS) as well as providing self-reported measures of height and weight. The 10-item MEC was developed. This measure was shown to have excellent internal consistency (Cronbach's alpha =.946), based on a single factor accounting for 67.4% of the variance and excellent test-retest reliability (r =.923). MEC10 score was strongly predictive of being categorised as having food addiction based on the YFAS, although not associated with BMI. This brief tool is likely to have high utility in clinical and research settings and requires further validation with a range of populations including those with and without obesity, binge eating disorder and other eating disorders.
食物成瘾日益被视为超重和肥胖的一个促成因素。饮食强迫行为是食物成瘾的关键组成部分，对其进行管理可能会极大地有助于肥胖症的成功治疗。测量食物成瘾及其饮食强迫行为的核心特征，对于增进对食物成瘾概念的理解、其在肥胖者和非肥胖者中的患病率以及其在治疗背景下的效用至关重要。当前的研究描述了一种简短的饮食强迫行为测量方法的开发和初步验证，该方法可用于临床和研究环境，以确定一个人的饮食强迫行为水平。从新西兰克赖斯特彻奇的普通人群样本中招募了65名BMI≥30（平均BMI 38.1）的参与者。参与者完成了饮食强迫行为测量量表（MEC）的测试版本和耶鲁食物成瘾量表（YFAS），并提供了自我报告的身高和体重测量值。开发了10项的MEC。该测量方法基于一个解释67.4%方差的单一因素，显示出极好的内部一致性（克朗巴哈系数=0.946）和极好的重测信度（r=0.923）。根据YFAS，MEC10得分强烈预测被归类为患有食物成瘾，尽管与BMI无关。这个简短的工具在临床和研究环境中可能具有很高的效用，并且需要在包括肥胖者和非肥胖者、暴饮暴食症和其他饮食失调者在内的一系列人群中进行进一步验证。
