Food choice values (FCVs) are factors that individuals consider when deciding which foods to purchase and/or consume. Given the potentially important implications for health, it is critical for researchers to have access to a validated measure of FCV. Though there is an existing measure of FCV, this measure was developed 20 years ago and recent research suggests additional FCVs exist that are not included in this measure. A series of four studies was conducted to develop a new expanded measure of FCV. An eight-factor model of FCV was supported and confirmed. In aggregate, results from the four studies indicate that the measure is content valid, and has internally consistent scales that also demonstrated acceptable temporal stability and convergent validity. In addition, the eight scales of the measures were independent of social desirability, met criteria for measurement invariance across income groups, and predicted dietary intake. The development of this new measure of FCV may be useful for researchers examining FCVs (FCVs) in the future, as well as for use in intervention and prevention efforts targeting dietary choices.
食物选择价值观（FCVs）是个体在决定购买和/或食用哪些食物时所考虑的因素。鉴于其对健康可能具有的重要影响，研究人员能够获取经过验证的FCV测量方法至关重要。尽管现已有一种FCV测量方法，但该方法是20年前开发的，近期研究表明还存在一些未包含在该方法中的其他FCVs。开展了一系列四项研究以开发一种新的扩展版FCV测量方法。一个八因素的FCV模型得到了支持和验证。总体而言，四项研究的结果表明该测量方法具有内容效度，其量表具有内部一致性，同时还表现出可接受的时间稳定性和收敛效度。此外，该测量方法的八个量表不受社会期望性的影响，符合不同收入群体测量不变性的标准，并能预测饮食摄入量。这种新的FCV测量方法的开发可能对未来研究FCVs的研究人员有用，也可用于针对饮食选择的干预和预防工作。
