Understanding factors that influence food choice may help improve diet quality. Factors that commonly affect adults' food choices have been described, but measures that identify and assess food choice factors specific to college students are lacking. This study developed and tested the Food Choice Priorities Survey (FCPS) among college students. Thirty-seven undergraduates participated in two focus groups ( n = 19; 11 in the male-only group, 8 in the female-only group) and interviews ( n = 18) regarding typical influences on food choice. Qualitative data informed the development of survey items with a 5-point Likert-type scale (1 = not important, 5 = extremely important). An expert panel rated FCPS items for clarity, relevance, representativeness, and coverage using a content validity form. To establish test-retest reliability, 109 first-year college students completed the 14-item FCPS at two time points, 0-48 days apart ( M = 13.99, SD = 7.44). Using Cohen's weighted κ for responses within 20 days, 11 items demonstrated moderate agreement and 3 items had substantial agreement. Factor analysis revealed a three-factor structure (9 items). The FCPS is designed for college students and provides a way to determine the factors of greatest importance regarding food choices among this population. From a public health perspective, practical applications include using the FCPS to tailor health communications and behavior change interventions to factors most salient for food choices of college students.
了解影响食物选择的因素可能有助于改善饮食质量。虽然已描述了通常影响成年人食物选择的因素,但缺乏识别和评估大学生特有的食物选择因素的措施。本研究开发并测试了针对大学生的食物选择优先级调查(FCPS)。37名本科生参加了两个焦点小组(n = 19;11人参加仅男性组,8人参加仅女性组)以及关于食物选择的典型影响因素的访谈(n = 18)。定性数据为采用5点李克特式量表(1 = 不重要,5 = 极其重要)的调查项目的开发提供了依据。一个专家小组使用内容效度表对FCPS项目的清晰度、相关性、代表性和涵盖范围进行了评分。为了建立重测信度,109名大学一年级学生在两个时间点完成了14项的FCPS,间隔0 - 48天(M = 13.99,SD = 7.44)。使用科恩加权κ系数对20天内的回答进行分析,11个项目显示出中等一致性,3个项目具有高度一致性。因子分析揭示了一个三因素结构(9个项目)。FCPS是为大学生设计的,提供了一种方法来确定该人群中与食物选择最为重要的因素。从公共卫生角度来看,实际应用包括使用FCPS来根据对大学生食物选择最突出的因素调整健康宣传和行为改变干预措施。
