Short message service (SMS)-based disaster alert systems are used as critical methods that inform people of natural disasters. This study investigates how two different decision-making routes influence adaptive copings based upon users’ protection motivations. The two important routes, argument quality and source credibility, are presented as focal antecedents of coping adaptiveness. And perceived threat and coping efficacy are tested as a moderator as elaboration likelihood. To achieve these goals, we propose a theoretical framework and analyze survey data to test the hypotheses. The results illustrate that two elaboration likelihood variables show significant moderating roles in the proposed research model.

基于短消息服务（SMS）的灾难警报系统被用作告知人们自然灾害的关键方法。这项研究基于用户的保护动机，研究了两种不同的决策途径如何影响适应性应对。提出两个重要的途径，即论据质量和来源可信度，作为应对适应性的重要前提。作为细化可能性的测试者，以感知的威胁和应对功效作为主持人进行了测试。为了实现这些目标，我们提出了一个理论框架并分析了调查数据以检验假设。结果表明，在拟议的研究模型中，两个拟订可能性变量显示出重要的调节作用。
