评估父母的儿童喂养行为是具有挑战性的，需要额外的方法方法。虚拟现实技术允许创建行为度量，它的实现克服了现有方法的几个限制。这份报告在52位3-7岁儿童的父母中评估了虚拟现实（VR）自助餐的有效性和可用性。参与者在虚拟环境和现实环境中都吃了一顿意大利面和苹果汁（通过分心任务来平衡和分开）。然后，他们为孩子制作了另一顿饭，这一次他们从虚拟现实自助餐的全套食物中进行选择。最后，参与者完成了一项食物评估任务，然后是一份问卷，评估他们对虚拟现实自助餐的看法。结果显示，父母提供的虚拟面食的量与他们提供的真实面食的量显著相关，r(s) = 0.613, p < 0.0001，虚拟苹果汁和真实苹果汁的量也显著相关，r(s) = 0.822, p < 0.0001。此外，父母对所选食物的卡路里含量的感知与观察到的卡路里含量显著相关（r(s) = 0.438, p = 0.002），父母同意他们会给孩子喂食他们制作的食物（M = 4.43, SD = 0.82, 1-5量表）。这里提供的数据表明，家长在虚拟现实自助餐中的行为与现实世界的行为高度相关，并且家长对该工具的评价很高。鉴于提供的数据和VR自助餐可以提供的丰富行为数据的潜在好处，我们得出结论，它是评估喂养行为的一系列工具的有效和必要的补充。Elsevier Ltd.出版。
Assessment of parents' child feeding behavior is challenging, and there is need for additional methodological approaches. Virtual reality technology allows for the creation of behavioral measures, and its implementation overcomes several limitations of existing methods. This report evaluates the validity and usability of the Virtual Reality (VR) Buffet among a sample of 52 parents of children aged 3-7. Participants served a meal of pasta and apple juice in both a virtual setting and real-world setting (counterbalanced and separated by a distractor task). They then created another meal for their child, this time choosing from the full set of food options in the VR Buffet. Finally, participants completed a food estimation task followed by a questionnaire, which assessed their perceptions of the VR Buffet. Results revealed that the amount of virtual pasta served by parents correlated significantly with the amount of real pasta they served, r(s) = 0.613, p < .0001, as did served amounts of virtual and real apple juice, r(s) = 0.822, p < .0001. Furthermore, parents' perception of the calorie content of chosen foods was significantly correlated with observed calorie content (r(s) = 0.438, p = .002), and parents agreed that they would feed the meal they created to their child (M = 4.43, SD = 0.82 on a 1-5 scale). The data presented here demonstrate that parent behavior in the VR Buffet is highly related to real-world behavior, and that the tool is well-rated by parents. Given the data presented and the potential benefits of the abundant behavioral data the VR Buffet can provide, we conclude that it is a valid and needed addition to the array of tools for assessing feeding behavior.
