Persuasive mental health applications (apps) are effective tools for promoting behavior change. Tailoring persuasive interventions can boost their effectiveness. Research has shown that there is a relationship between individuals’ personality traits and their susceptibility to various features of a persuasive app. The aim of this paper was twofold. First, we explore the relationships between personality and features of a persuasive app for promoting mental and emotional well-being. Second, we explore possible domain-dependent variability on the relation between personality and persuasive features across various domains (e.g., habit formation, fitness, risky behaviors change, transportation habits). Specifically, to advance research in the area of personality and computing app design, first, we reviewed 103 mental health apps from the app stores and uncovered the various persuasive features employed in their design. Second, we conducted focus-group studies of 32 participants to uncover more insights about the mental health app features. Finally, we implemented the common features that emerged from these two studies in persuasive mental health app prototypes and conducted a large-scale study of 561 users to evaluate their persuasiveness depending on people’s personalities. The results of the large-scale study show that people’s personality traits play a significant role in the perceived persuasiveness of different features—the app features that appeal to various individuals. Conscientious people tend to be motivated by apps that offer relaxation audios, encouragement, suggestions and trusted information, contact for help; Neurotic people are more inclined to apps that provide some relaxation exercises and audios, social support, and apps with a clear privacy policy; People who are more open to experience tend to be motivated by self-monitoring, relaxation exercises and audios, and social support. Finally, we provide a comparative analysis of the relationship between personality traits and persuasive features across various domains to show domain dependency of persuasive feature effectiveness and offer design guidelines for tailoring persuasive and behavior change apps based on an individual’s personality.

有说服力的心理健康应用程序（应用程序）是促进行为改变的有效工具。量身定制有说服力的干预措施可以提高其有效性。研究表明，个人的个性特征与他们对说服性应用程序的各种功能的敏感性之间存在关系。本文的目的是双重的。首先，我们探索个性与有说服力的应用程序功能之间的关系，以促进心理和情感健康。其次，我们探讨了个性与跨领域（例如，习惯形成、健康、危险行为改变、交通习惯）之间的说服特征之间关系的可能的领域相关变异性。具体来说，为了推进个性和计算应用程序设计领域的研究，首先，我们审查了来自应用商店的 103 款心理健康应用，并发现了它们设计中采用的各种有说服力的功能。其次，我们对 32 名参与者进行了焦点小组研究，以发现有关心理健康应用程序功能的更多见解。最后，我们在有说服力的心理健康应用程序原型中实现了这两项研究中出现的共同特征，并对 561 名用户进行了大规模研究，以根据人们的个性评估他们的说服力。大规模研究的结果表明，人们的个性特征在不同功能的感知说服力中起着重要作用 - 应用程序功能对不同的人有吸引力。我们对 32 名参与者进行了焦点小组研究，以发现有关心理健康应用程序功能的更多见解。最后，我们在有说服力的心理健康应用程序原型中实现了这两项研究中出现的共同特征，并对 561 名用户进行了大规模研究，以根据人们的个性评估他们的说服力。大规模研究的结果表明，人们的个性特征在不同功能的感知说服力中起着重要作用 - 应用程序功能对不同的人有吸引力。我们对 32 名参与者进行了焦点小组研究，以发现有关心理健康应用程序功能的更多见解。最后，我们在有说服力的心理健康应用程序原型中实现了这两项研究中出现的共同特征，并对 561 名用户进行了大规模研究，以根据人们的个性评估他们的说服力。大规模研究的结果表明，人们的个性特征在不同功能的感知说服力中起着重要作用 - 应用程序功能对不同的人有吸引力。有责任心的人往往会受到提供放松音频、鼓励、建议和可信信息、寻求帮助的应用程序的激励；神经质的人更倾向于提供一些放松练习和音频、社交支持以及有明确隐私政策的应用程序；对体验更开放的人往往会受到自我监控、放松练习和音频以及社会支持的激励. 最后，我们对不同领域的个性特征和说服特征之间的关系进行了比较分析，以显示说服特征有效性的领域依赖性，并提供基于个人个性定制说服和行为改变应用程序的设计指南。
