The aim of this study was to verify whether appetite sensation scores obtained from 150-mm visual analogue scales (VAS) can be compared to those obtained from 100-mm scales. On one occasion, using a within-subject design, 25 participants (mean age: 42.2 + or - 13.3 years, mean body mass index: 22.9 + or - 2.3 kg/m(2)) recorded their appetite sensations before lunch, and at five additional time points during the postprandial period. At each time point, both VAS (150 mm and 100 mm) were used to record desire to eat, hunger, fullness, satiety, and prospective food consumption. The VAS in the same booklet were completed immediately one after the other in a randomized order to eliminate the order effect. We observed that the immediate, successive completion of questionnaires varying in length resulted in no significant difference in appetite markers, with a strong linear relationship between the two tools (r from 0.80 to 0.98, P<0.01). We conclude that VAS scores obtained from 150-mm to 100-mm length scales are interchangeable, both before and in response to a meal.
本研究旨在验证 150 毫米视觉模拟量表（VAS）获得的食欲感知评分是否可以与 100 毫米量表获得的评分进行比较。在一项采用自身对照设计的研究中，25 名参与者（平均年龄：42.2 ± 13.3 岁，平均体重指数：22.9 ± 2.3 kg/m2）在午餐前和餐后的五个额外时间点记录了他们的食欲感知。在每个时间点，都使用两种 VAS（150 毫米和 100 毫米）来记录进食欲望、饥饿感、饱腹感、满足感和预期食物摄入量。为了消除顺序效应，同一本小册子中的 VAS 以随机顺序连续完成。我们观察到，在长度不同的问卷立即连续完成时，食欲标志物没有显著差异，两种工具之间具有很强的线性关系（r 值从 0.80 到 0.98，P<0.01）。我们得出结论，150 毫米到 100 毫米长度量表的 VAS 评分在餐前和餐后是可互换的。
