Because overconsumption of food contributes to ill health, understanding what affects how much people eat is of importance. The 'bogus' taste test is a measure widely used in eating behaviour research to identify factors that may have a causal effect on food intake. However, there has been no examination of the validity of the bogus taste test as a measure of food intake. We conducted a participant level analysis of 31 published laboratory studies that used the taste test to measure food intake. We assessed whether the taste test was sensitive to experimental manipulations hypothesized to increase or decrease food intake. We examined construct validity by testing whether participant sex, hunger and liking of taste test food were associated with the amount of food consumed in the taste test. In addition, we also examined whether BMI (body mass index), trait measures of dietary restraint and over-eating in response to palatable food cues were associated with food consumption. Results indicated that the taste test was sensitive to experimental manipulations hypothesized to increase or decrease food intake. Factors that were reliably associated with increased consumption during the taste test were being male, have a higher baseline hunger, liking of the taste test food and a greater tendency to overeat in response to palatable food cues, whereas trait dietary restraint and BMI were not. These results indicate that the bogus taste test is likely to be a valid measure of food intake and can be used to identify factors that have a causal effect on food intake.
由于食物摄入过量会导致健康问题，因此了解影响人们食量的因素至关重要。“假”味觉测试是饮食行为研究中广泛使用的一种测量方法，用于确定可能对食物摄入量产生因果影响的因素。然而，尚未有人对“假”味觉测试作为食物摄入量测量方法的有效性进行检验。我们对31项已发表的实验室研究进行了参与者层面的分析，这些研究使用味觉测试来测量食物摄入量。我们评估了味觉测试是否对假设会增加或减少食物摄入量的实验操作敏感。我们通过测试参与者的性别、饥饿程度以及对味觉测试食物的喜好是否与味觉测试中的食物摄入量相关来检验结构效度。此外，我们还研究了体重指数（BMI）、饮食克制的特质测量以及对美味食物线索的过度进食反应是否与食物消费相关。结果表明，味觉测试对假设会增加或减少食物摄入量的实验操作敏感。在味觉测试中，与摄入量增加可靠相关的因素包括男性、较高的基线饥饿程度、对味觉测试食物的喜好以及对美味食物线索有更大的过度进食倾向，而饮食克制特质和BMI则不然。这些结果表明，“假”味觉测试可能是一种有效的食物摄入量测量方法，可用于识别对食物摄入量有因果影响的因素。
