饮食模式的异常构成了巨大的公共卫生负担。以计算机为基础的范例，测量对食物的图像的反应是潜在的有用的工具，用于评估食物的态度和饮食行为的特点。特别是，食物选择任务试图直接探索个人关于吃什么的决定的各个方面。在食物选择任务中，参与者每次对一种食物的健康和美味进行评分。接下来，参与者为每种食物选择他们是否更喜欢吃该食物，而不是中立评级的参考食物。本研究的目的是评估食物选择任务随着时间的推移和重复测试的稳定性和可靠性。二次分析是使用两项独立研究中健康志愿者的数据进行的，这些研究在两个时间点进行任务，间隔几天或大约一个月。使用组内相关系数评估多次给药的食物选择任务的总体可靠性，使用Kappa系数评估单个食物项目评级的可靠性。结果表明，食物选择任务在健康志愿者中的重测信度在较短和较长的重测间隔下均较高。此外，个别食品项目评级的可靠性是好的大部分项目。在这两项研究中，健康志愿者选择高脂肪食物的比例并没有随着时间的推移而改变。因此，食物选择任务适用于测量具有多个评估点的研究中的食物选择。特别是，该任务可能非常适合评估限制性饮食，这是一种在实验环境中难以评估的结构。
Aberrations in eating patterns constitute a substantial public health burden. Computer-based paradigms that measure responses to images of foods are potentially useful tools for assessing food attitudes and characteristics of eating behavior. In particular, food choice tasks attempt to directly probe aspects of individuals’ decisions about what to eat. In the Food Choice Task participants rate the healthiness and tastiness of a variety of food items presented one at a time. Next, participants choose for each food item whether they prefer to eat the item vs. a neutrally rated reference food item. The goal of the current study was to assess the stability and reliability of this Food Choice Task over time and with repeated testing. Secondary analyses were conducted using data from healthy volunteers in two separate studies that administered the task at two time points, separated either by several days or about a month. The overall reliability of the Food Choice Task across multiple administrations was assessed using intra-class correlation coefficients and the reliability of ratings of individual food items was assessed using kappa coefficients. The results indicated that test-retest reliability of the Food Choice Task in healthy volunteers was high at both shorter and longer test-retest intervals. In addition, the reliability of individual food item ratings was good for a majority of items. The proportion of healthy volunteers’ high-fat food choices did not change over time in either of the two studies. Thus, the Food Choice Task is suitable for measuring food choices in studies with multiple assessment points. In particular, the task may be well suited to assess restrictive eating, a construct which it has been difficult to assess in experimental settings.
