Children are vulnerable to adverse effects of food advertising. Food commercials are known to increase hedonic, taste-oriented, and unhealthy food decisions. The current study examined how promoting resilience to food commercials impacted susceptibility to unhealthy food decision-making in children. To promote resilience to food commercials, we utilized the food advertising literacy intervention intended to enhance cognitive skepticism and critical thinking, and decrease positive attitudes toward commercials. Thirty-six children aged 8-12 years were randomly assigned to the food advertising literacy intervention or the control condition. Eighteen children received four brief intervention sessions via video over 1 week period. In each session, children watched six food commercials with interspersed embedded intervention narratives. While watching food commercials and narratives, children were encouraged to speak their thoughts out loud spontaneously ("think-aloud"), which provided children's attitudes toward commercials. Eighteen children in the control condition had four control sessions over 1 week, and watched the same food commercials without intervention narratives while thinking aloud. The first and last sessions were held in the laboratory, and the second and third sessions were held at the children's homes. Susceptibility to unhealthy food decision-making was indicated by the decision weights of taste attributes, taste perception, food choices, snacking, and cognitive and affective attitudes toward food commercials. As hypothesized, the intervention successfully decreased susceptibility to unhealthy food decision-making evidenced by reduced decision weights of the taste in food decisions, decreased tasty perception of unhealthy foods, and increased cognitive skepticism and critical thinking toward food commercials. In addition, as children's opinions assimilated to intervention narratives, their cognitive skepticism and critical thinking toward commercials increased. The aforementioned results were not shown in the control condition. However, this brief intervention was not enough to change actual food choices or food consumption. Results of this study suggest that promoting resilience to food commercials by enhancing cognitive skepticism and critical thinking effectively reduced children's susceptibility to unhealthy food-decision making.
儿童易受食品广告的不良影响。众所周知,食品广告会增加享乐主义、以口味为导向以及不健康的食品决策。当前的研究考察了提升对食品广告的抵抗力如何影响儿童做出不健康食品决策的易感性。为了提升对食品广告的抵抗力,我们采用了食品广告素养干预措施,旨在增强认知怀疑主义和批判性思维,并减少对广告的积极态度。36名8至12岁的儿童被随机分配到食品广告素养干预组或对照组。18名儿童在1周的时间内通过视频接受了4次简短的干预课程。在每次课程中,儿童观看6个食品广告,并穿插有嵌入式干预叙述。在观看食品广告和叙述时,鼓励儿童自发地大声说出他们的想法(“边想边说”),这提供了儿童对广告的态度。对照组的18名儿童在1周内进行了4次对照课程,并在边想边说的同时观看了没有干预叙述的相同食品广告。第一次和最后一次课程在实验室进行,第二次和第三次课程在儿童家中进行。对不健康食品决策的易感性通过口味属性的决策权重、味觉感知、食品选择、吃零食以及对食品广告的认知和情感态度来表示。正如所假设的那样,干预成功降低了对不健康食品决策的易感性,这表现为食品决策中口味的决策权重降低、对不健康食品的美味感知降低,以及对食品广告的认知怀疑主义和批判性思维增加。此外,随着儿童的观点与干预叙述趋同,他们对广告的认知怀疑主义和批判性思维也增加了。上述结果在对照组中并未出现。然而,这种简短的干预不足以改变实际的食品选择或食品消费。本研究结果表明,通过增强认知怀疑主义和批判性思维来提升对食品广告的抵抗力,有效地降低了儿童做出不健康食品决策的易感性。
