The two studies describe the development of three complementary scales to the Food Choice Questionnaire developed by Steptoe, Pollard & Wardle (1995). The new items address various ethical food choice motives and were derived from previous studies on vegetarianism and ethical food choice. The items were factor analysed in Study 1 (N=281) and the factor solution was confirmed in Study 2 (N=125), in which simple validity criteria were also included. Furthermore, test-retest reliability was assessed with a separate sample of subjects (N=36). The results indicated that the three new scales, Ecological Welfare (including subscales for Animal Welfare and Environment Protection), Political Values and Religion, are reliable and valid instruments for a brief screening of ethical food choice reasons.
这两项研究描述了针对Steptoe、Pollard和Wardle（1995年）编制的食物选择问卷开发的三个补充量表的情况。新的项目涉及各种符合道德的食物选择动机，这些动机源自之前关于素食主义和符合道德的食物选择的研究。在研究1（N = 281）中对这些项目进行了因子分析，并在研究2（N = 125）中对因子分析结果进行了验证，研究2还纳入了简单的效度标准。此外，还使用另一组单独的受试者样本（N = 36）评估了重测信度。结果表明，生态福利（包括动物福利和环境保护子量表）、政治价值观和宗教这三个新量表是用于简要筛选符合道德的食物选择原因的可靠且有效的工具。
