本研究旨在扩展有关促进健康饮食行为的短信干预的文献。其理论框架是计划行为理论（TPB）。一项随机对照试验被用来测试每天发短信与不发短信（组）相比在2周内减少加工肉类消费量（PMC）的影响，测试预期后悔和意图对组与PMC减少之间关系的顺序中介作用。在时间1和时间2评估PMC和TPB变量。参与者是意大利本科生（在时间1 N = 124）随机分配到控制和消息条件组。消息条件组的本科生每天都会收到一条短信，重点是预期的遗憾，并敦促他们自我监控PMC。对照组的参与者没有收到任何消息。在两个时间点完成所有测量的受试者纳入分析（N = 112）。研究结果表明，每天的信息干预，控制参与者的过去的行为，减少自我报告的PMC消费。调解分析表明，部分串行调解通过预期的遗憾和意图。目前的研究提供了支持的有效性，每天的消息干预针对预期的遗憾，并鼓励自我监控，减少PMC。结果表明，预期的遗憾和意图减少PMC的重要中介作用。(C)2017爱思唯尔有限公司版权所有
The present study aimed to extend the literature on text messaging interventions involved in promoting healthy eating behaviours. The theoretical framework was the Theory of Planned Behaviour (TPB). A randomized controlled trial was used to test the impact of daily text messages compared to no message (groups) for reducing processed meat consumption (PMC) over a 2 week period, testing the sequential mediation role of anticipated regret and intention on the relationship between groups and PMC reduction. PMC and TPB variables were assessed both at Time 1 and Time 2. Participants were Italian undergraduates (at Time 1 N = 124) randomly allocated to control and message condition groups. Undergraduates in the message condition group received a daily SMS, which focused on anticipated regret and urged them to self-monitor PMC. Participants in the control group did not receive any message. Those who completed all measures at both time points were included in the analyses (N = 112). Findings showed that a daily messaging intervention, controlling for participants' past behaviour, reduced self reported consumption of PMC. Mediation analyses indicated partial serial mediation via anticipated regret and intentions. The current study provided support for the efficacy of a daily messaging intervention targeting anticipated regret and encouraging self-monitoring in decreasing PMC. Outcomes showed the important mediating role of anticipated regret and intentions for reducing PMC. (C) 2017 Elsevier Ltd. All rights reserved.
