A majority of children's restaurant meals are nutritionally deficient; use of behavioral economics may improve healthful menu selections. Parents play a role in children's restaurant meal selection, thus understanding parent preferences for potential behavioral economic strategies is warranted.
To examine parent-derived and -stated preferences for selected attributes of children's restaurant menus, which included behavioral economic strategies (eg, optimal defaults and vice-virtue bundles).
A descriptive, cross-sectional, within-subjects survey integrating a conjoint design was developed along with 8 children's menus. Menus were manipulated by varying levels of attributes (meal price, healthful side dishes, number of side dish items, healthful entrées, and cost for sugar-sweetened beverages [SSB]). Parents rated menus and attributes using Likert scales.
PARTICIPANTS/SETTING: A national sample of US parents with children 4 to 10 years (n = 463) were recruited in August of 2019 via Amazon's Mechanical Turk.
A conjoint (regression) analysis was conducted to derive parent preference for each attribute and overall menu preference. Descriptive statistics (means) described overall stated parent menu preferences and ratings. Cluster analysis segmented parents into groups with similar preferences.
Derived preferences showed parents had the strongest preference for choice of side dishes (β = .73) and low-priced menus (β = .51), and weak preferences for inclusion of healthful entrées (β = .04) and added cost for SSB (β = .18). Parents stated preference was for a menu that included healthful entrées, was low priced, and featured choices for side dishes. Cluster analysis revealed half of parents preferred the low-cost children's menu with the other half of parents split evenly across preferences related to health, choice, and traditional menus.
Parents stated preference was for a socially desirable menu featuring healthful entrée options and added cost for SSB, which was contrary to the conjoint derived menu preferences. Understanding parent preferences may help guide nutrition professionals working to build a more healthful food environment through the use of behavioral economic strategies.
大多数儿童餐厅的餐食在营养上都存在不足;利用行为经济学可能会改善健康菜单选择。父母在儿童餐厅的点餐中扮演着重要的角色,因此了解父母对潜在行为经济策略的偏好是合理的。
研究父母对儿童餐厅菜单的某些属性的偏好,包括行为经济学策略(例如最佳默认选项和反向美德捆绑)。
采用描述性、横截面、个体内的调查设计,结合了联合设计和 8 份儿童菜单。通过改变属性(餐价、健康配菜、配菜项目数量、健康主菜和含糖饮料 [SSB] 的成本)来操纵菜单。父母使用李克特量表对菜单和属性进行评分。
参与者/设置:2019 年 8 月,通过亚马逊的 Mechanical Turk 招募了具有 4 至 10 岁儿童的美国全国父母样本(n=463)。
进行联合(回归)分析,得出父母对每个属性和整体菜单偏好的偏好。描述性统计(平均值)描述了父母对整体菜单偏好和评分的偏好。聚类分析将父母分成具有相似偏好的群体。
衍生偏好表明,父母对配菜选择的偏好最强(β=.73),对低价菜单的偏好最强(β=.51),对健康主菜的偏好较弱(β=.04),对 SSB 的附加成本的偏好较弱(β=.18)。父母的表述偏好是包含健康主菜、价格低廉且提供配菜选择的菜单。聚类分析显示,一半的父母更喜欢低成本的儿童菜单,另一半父母则平均分布在与健康、选择和传统菜单相关的偏好上。
父母的表述偏好是具有健康主菜选择和 SSB 附加成本的理想菜单,这与联合衍生的菜单偏好相反。了解父母的偏好可能有助于指导营养专业人员通过使用行为经济学策略来努力营造更健康的饮食环境。
