The reliability and validity of an Estimated Daily Intake Scale for Fat (EDIS-F) used to measure daily intake of fat in a participant's diet was tested. A Cronbach's alpha was used to determine the reliability of the EDIS-F. To determine the validity of this scale, scores on this scale were correlated with known factors related to daily intake of fat (e.g., ratings of liking for a high fat food and the body mass index score of participants). A 13-item EDIS-F was shown to be reliable, and scores on the EDIS-F significantly correlated with ratings of liking for a high fat cream cheese cracker and BMI, but not with gender, consistent with the assertion that this scale measures daily intake of fat. Implications for using this scale are discussed.
用于测量参与者饮食中每日脂肪摄入量的脂肪估计每日摄入量量表（EDIS-F）的信度和效度进行了测试。使用克朗巴哈系数来确定EDIS-F的信度。为了确定该量表的效度，将该量表的得分与与每日脂肪摄入量相关的已知因素（如对高脂肪食物的喜爱程度评分和参与者的体重指数得分）进行相关性分析。一个包含13个条目的EDIS-F被证明是可靠的，并且EDIS-F的得分与对高脂肪奶油芝士饼干的喜爱程度评分和体重指数显著相关，但与性别无关，这与该量表测量每日脂肪摄入量的说法一致。文中讨论了使用该量表的意义。
