Digitizing the Pre-consultation Experience: Impacts and Design Recommendations

Clinical pre-consultation, where patients share health information prior to an appointment, offers a pathway to more patient-centered care by freeing time for meaningful patient–physician conversations. Conversational agents powered by large language models (LLMs) can automate this process to make it more scalable and…

Investigating the Role of Situational Disruptors in Engagement with Digital Mental Health Tools

Challenges in engagement with digital mental health (DMH) tools are commonly addressed through technical enhancements and algorithmic interventions. This paper shifts the focus towards the role of users' broader social context as a significant factor in engagement. Through an eight-week text messaging program aimed at…

Perfectly to a Tee: Understanding User Perceptions of Personalized LLM-Enhanced Narrative Interventions

Stories about overcoming personal struggles can effectively illustrate the application of psychological theories in real life, yet they may fail to resonate with individuals' experiences. In this work, we employ large language models (LLMs) to create tailored narratives that acknowledge and address unique challenging…

A Comparative Analysis of Information Gathering by Chatbots, Questionnaires, and Humans in Clinical Pre-Consultation

Information gathering is an important capability that allows chatbots to understand and respond to users' needs, yet the effectiveness of LLM-powered chatbots at this task remains underexplored. Our work investigates this question in the context of clinical pre-consultation, wherein patients provide information to an…

Promoting Engagement in Remote Patient Monitoring Using Asynchronous Messaging

Remote patient monitoring is becoming increasingly instrumental to healthcare delivery but can substantially hamper the interpersonal communication that underlies standard clinical practice. In this work, we explore the benefits imparted to patients, clinicians, and researchers by an asynchronous messaging feature wit…

Understanding the Role of Large Language Models in Personalizing and Scaffolding Strategies to Combat Academic Procrastination

Traditional interventions for academic procrastination often fail to capture the nuanced, individual-specific factors that underlie them. Large language models (LLMs) hold immense potential for addressing this gap by permitting open-ended inputs, including the ability to customize interventions to individuals' unique…

Beyond the Waiting Room: Patient's Perspectives on the Conversational Nuances of Pre-Consultation Chatbots

Pre-consultation serves as a critical information exchange between healthcare providers and patients, streamlining visits and supporting patient-centered care. Human-led pre-consultations offer many benefits, yet they require significant time and energy from clinical staff. In this work, we identify design goals for p…

Leveraging Idle Games to Incentivize Intermittent and Frequent Practice of Deep Breathing

The need for frequent and brief practice in deep breathing presents challenges in maintaining motivation and consistency. While persuasive technologies have been shown to improve engagement in therapeutic exercises, there is a lack of insight into specific motivational strategies for such intermittent activities. We…

Functional Design Requirements to Facilitate Menstrual Health Data Exploration

Menstrual trackers currently lack the affordances required to help individuals achieve their goals beyond menstrual event predictions and symptom logging. Taking an initial step towards this aspiration, we propose, validate, and refine five functional design requirements for future interface designs that facilitate me…
