Healthy eating among young people may curb obesity and improve health, but strong messaging is needed for healthy eating interventions. In the current work, we evaluated the usefulness of visual appeals in a pilot text message-based healthy eating intervention among college students. A 2 (gain vs. loss) × 2 (image vs. no image) design with pretest and posttest questionnaires (N = 111) revealed text-only messages with loss frames had an influence on affective risk response, while both gain- and loss-framed text messages with visual appeals had positive effects on attitudes and intentions. This pilot study provides evidence to support the feasibility of using visual appeals in text message-based health interventions. The implications of the current study are discussed.
年轻人健康饮食可以控制肥胖，改善健康，但健康饮食干预需要强有力的信息传递。在当前的工作中，我们评估了在基于短信的大学生健康饮食干预中使用视觉效果的有用性。一项 2（收益与损失）×2（有图像与无图像）的设计，结合前测和后测问卷（N=111）显示，带有损失框架的纯文本信息对情感风险反应有影响，而带有视觉效果的收益和损失框架的文本信息都对态度和意图有积极影响。这项初步研究提供了证据支持在基于短信的健康干预中使用视觉效果的可行性。讨论了当前研究的意义。
