Understanding Adults’ Acceptance of AI-Enabled Physician Chatbots for Self-Diagnosis: Development and Validation of the Digital Health Value-Acceptance of Technology (DHVAT) Framework
This study developed and validated the Digital Health Value-Acceptance of Technology (DHVAT) framework using data from 740 Saudi adults, revealing that the acceptance of AI physician chatbots for self-diagnosis is primarily driven by perceived self-management benefits and trust rather than raw diagnostic capability or direct risk accountability.

In the modern world, managing a long-term health condition often feels like a second job. Patients must track symptoms, remember medications, and navigate complex medical advice every single day. As healthcare moves online, artificial intelligence has entered the conversation, promising to act as a tireless assistant. These digital tools, often called chatbots, are designed to talk with patients, answer questions, and even suggest what might be wrong based on described symptoms. For years, the focus of these technologies has been on their ability to diagnose diseases accurately, much like a doctor would. However, a diagnosis is only the beginning of the journey for someone living with a chronic illness. The real challenge lies in the daily work of living well with that condition. While technology experts have spent decades studying why people accept new gadgets, the specific reasons why patients would trust a machine with their personal health data and daily care remain less clear, especially in regions where language and cultural trust play a major role.
A researcher in Saudi Arabia set out to understand this gap. They wanted to know what truly drives an adult to use an AI chatbot for their health. Instead of assuming that better diagnostic accuracy would lead to more usage, they proposed a different idea: that people care more about whether the tool helps them manage their daily lives and whether they feel safe using it. To test this, they developed a new framework called the Digital Health Value-Acceptance of Technology model. This approach shifts the focus from the machine's raw power to the human experience of using it. The researcher surveyed 740 adults across Saudi Arabia, asking them detailed questions about their views on AI health tools, their trust in technology, and their willingness to use these systems for self-diagnosis and care.
The study revealed a clear and surprising priority for patients. The strongest factor predicting whether someone would use an AI chatbot was not the tool's ability to diagnose a disease, but rather the patient's belief that the tool would help them manage their condition. When people felt that a chatbot could assist with lifestyle changes, medication reminders, or understanding their symptoms in a way that fit their daily routine, their intention to use it soared. This sense of practical help, or self-management benefit, was the most powerful driver of acceptance. The second most important factor was trust and safety. Patients needed to feel confident that the advice given by the machine was reliable and that their personal data was secure. Without this sense of security, even a helpful tool was unlikely to be adopted.
Interestingly, the study found that concerns about who is responsible if the AI makes a mistake did not directly stop people from wanting to use the technology. Instead, these worries about accountability and risk influenced how much value patients saw in the tool for managing their health. If a patient felt the risks were too high or the rules too unclear, they were less likely to believe the tool would help them manage their condition, and that loss of perceived benefit reduced their willingness to use it. This suggests that the barrier is not a direct fear of the machine, but a doubt about its overall value when safety and responsibility are in question. The researcher also found that a person's comfort with technology played a significant role. Those with higher computer skills were more likely to see the benefits and feel safer using these tools, while those with less experience tended to be more skeptical. This points to a digital divide where skills, rather than age or education, determine how people view these new health aids.
When the researcher asked participants to describe their thoughts in their own words, a pattern emerged. People were eager for tools that offered continuous support, such as 24-hour access to guidance or help preparing for doctor visits. However, their fears were equally specific. The most common worry was that the AI might give incorrect advice or misunderstand symptoms, leading to delayed professional care. Many participants emphasized that they wanted these tools to act as assistants to doctors, not replacements. They insisted on clear rules about who is responsible if something goes wrong and demanded strong protections for their private health information. The data showed that while many people were aware of existing government health apps, fewer knew about the newer AI features, suggesting a need for better communication about what these tools can actually do.
The findings suggest that the future of AI in healthcare depends less on making machines smarter at diagnosing diseases and more on making them better partners in daily life. For these tools to succeed, they must be designed to support the patient's daily routine and be backed by transparent rules that ensure safety and accountability. The study indicates that if developers focus on building trust and demonstrating clear value for self-management, patients will be willing to embrace these technologies. The research does not claim that AI is ready to replace doctors, but rather that it can become a valuable part of the healthcare team if it is introduced with care, oversight, and a clear understanding of what patients actually need. By addressing the human side of the equation—trust, safety, and daily utility—health systems can turn these digital tools into genuine assets for people managing chronic conditions.
