人工智能为人类与医学实践技术的互动提供了新的机会。在最近的人工智能创新中，个人语音助理已被广泛采用。这突出了它们在医疗保健相关应用方面的潜力，例如行为咨询，以促进健康的生活习惯和情感健康。然而，使用基于语音的应用程序进行行为治疗之前尚未进行过评估。这项研究旨在对Lumen进行形成性用户评估，Lumen是一种基于语音的虚拟教练，作为Alexa技能开发，为轻度至中度抑郁和/或焦虑患者提供基于证据的解决问题的治疗。共有26名参与者完成了2个治疗课程-介绍（课程1）和解决问题（课程2）-与流明。在与Lumen的每次会议之后，参与者完成了用户体验，任务相关的工作量和工作联盟调查。他们还参加了半结构化访谈，讨论了Lumen使用的好处、挑战和障碍，以及设计建议。我们使用双尾配对t检验评估了会话之间在用户体验、任务负载和工作联盟方面的差异。使用归纳主题分析对访谈记录进行编码，以描述参与者对Lumen使用的观点。参与者发现Lumen提供了高度实用的可用性和良好的用户体验，在两个Lumen会话的交互过程中具有边际任务负载。然而，参与者在解决问题的过程中经历了更高的时间工作量，这表明他们在沟通互动过程中有一种匆忙的感觉。在定性分析的基础上，确定了以下主题：Lumen的按需可访问性和提供一个复杂的解决问题的治疗任务，具有实现治疗目标的简单化结构;与Lumen改进相关的主题包括简化和改进的个性化对话，较慢的对话节奏，并在治疗过程中提供额外的背景。在深入的形成性评估的基础上，我们发现Lumen支持为行为治疗提供认知上合理的互动的能力。从研究中确定的几个设计建议，包括减少会话交互过程中的时间和认知负荷，开发更自然的对话，以及扩展隐私和安全功能，都被纳入了Lumen的修订版中。虽然还需要进一步的研究，但这项研究的可喜发现突出了使用Lumen提供个性化和可访问的心理健康护理的潜力，填补了传统心理健康服务的空白。
Artificial intelligence has provided new opportunities for human interactions with technology for the practice of medicine. Among the recent artificial intelligence innovations, personal voice assistants have been broadly adopted. This highlights their potential for health care–related applications such as behavioral counseling to promote healthy lifestyle habits and emotional well-being. However, the use of voice-based applications for behavioral therapy has not been previously evaluated. This study aimed to conduct a formative user evaluation of Lumen, a virtual voice-based coach developed as an Alexa skill that delivers evidence-based, problem-solving treatment for patients with mild to moderate depression and/or anxiety. A total of 26 participants completed 2 therapy sessions—an introductory (session 1) and a problem-solving (session 2)—with Lumen. Following each session with Lumen, participants completed user experience, task-related workload, and work alliance surveys. They also participated in semistructured interviews addressing the benefits, challenges and barriers to Lumen use, and design recommendations. We evaluated the differences in user experience, task load, and work alliance between sessions using 2-tailed paired t tests. Interview transcripts were coded using an inductive thematic analysis to characterize the participants’ perspectives regarding Lumen use. Participants found Lumen to provide high pragmatic usability and favorable user experience, with marginal task load during interactions for both Lumen sessions. However, participants experienced a higher temporal workload during the problem-solving session, suggesting a feeling of being rushed during their communicative interactions. On the basis of the qualitative analysis, the following themes were identified: Lumen’s on-demand accessibility and the delivery of a complex problem-solving treatment task with a simplistic structure for achieving therapy goals; themes related to Lumen improvements included streamlining and improved personalization of conversations, slower pacing of conversations, and providing additional context during therapy sessions. On the basis of an in-depth formative evaluation, we found that Lumen supported the ability to conduct cognitively plausible interactions for the delivery of behavioral therapy. Several design suggestions identified from the study including reducing temporal and cognitive load during conversational interactions, developing more natural conversations, and expanding privacy and security features were incorporated in the revised version of Lumen. Although further research is needed, the promising findings from this study highlight the potential for using Lumen to deliver personalized and accessible mental health care, filling a gap in traditional mental health services.
