为了在大规模研究中评估家庭食物浪费，以了解家庭之间食物浪费水平的差异，通常采用调查方法。然而，调查措施依赖于人们对自己食物浪费水平的认识，利用他们对食物浪费实例的记忆，并且可能受到社会的欢迎。因此，现有的调查措施可能不是衡量家庭食物浪费的最佳方法。家庭食物垃圾问卷是为了改善这些问题而制定的。它使用预先公告来提高对食物浪费的认识，侧重于短而具体的时间段（即过去一周），并指定详细的产品类别，而以前的调查大多使用一般性问题，没有提及时间段或产品类别。使用家庭食物垃圾问卷估计的家庭食物垃圾数量可能大大低估了实际数量，因此该方法不应用于获得准确的垃圾数量，而应用于区分家庭之间和/或不同时间之间的差异。与现有的调查方法相比，它的优点是：更好地区分食物浪费低水平和高水平的家庭；与家庭食物浪费的其他测量方法（日记、厨房球盒、照片编码）的相关性更高(C) 2019作者。Elsevier B.V.出版
To assess household food waste in large-scale studies with the aim to understand differences in food waste levels between households, surveys are often employed. Yet, survey measures rely on people's awareness of their own food waste levels, draw upon their memory of instances of food waste, and can be subject to social desirability. Therefore, existing survey measures may not be optimal in measuring household food waste. The Household Food Waste Questionnaire has been developed to ameliorate these issues. It uses a pre-announcement to increase awareness of food waste, focuses on a short and specific time period (i.e. the past week), and specifies detailed product categories, whereas previous surveys mostly used general questions without reference to time period or product category. The amount of household food waste estimated using the Household Food Waste Questionnaire is likely to considerably underestimate the actual amount, so the method should not be used to obtain accurate waste amounts, but rather to distinguish differences between households and/or across time. Advantages compared to existing survey methods are that it:Distinguishes better between households with low versus high levels of food wasteCorrelates more highly with other measurements of household food waste (diary, kitchen caddy, photograph coding) (C) 2019 The Authors.
