Japanese Trainees' Perspectives on AI in Medicine

Juntendo University Research Promotion Center

Artificial intelligence (AI) is rapidly transforming healthcare and medical education. From enhancing diagnostic accuracy and clinical decision-making to enabling virtual simulations and personalized learning, AI technologies are becoming embedded in the daily practice of clinicians and trainees. Despite these benefits, concerns remain regarding ethical responsibility, data privacy, the loss of human autonomy, and potential job displacement. As AI continues to expand across medical systems worldwide, understanding how future physicians perceive and engage with these technologies is increasingly important.

Attitudes toward AI play a critical role in determining whether AI tools are accepted, trusted, and effectively integrated into clinical practice and education. Positive attitudes promote openness and responsible use, whereas negative perceptions may lead to skepticism and underutilization. Accurate measurement of attitudes toward AI among medical students and residents is, therefore, essential for identifying barriers to adoption and designing effective educational interventions. In 2024, Stein and colleagues introduced the 12-item attitudes towards artificial intelligence (ATTARI-12) scale, a brief and reliable measure encompassing affective, cognitive, and behavioral dimensions. However, the absence of a validated Japanese version limited its applicability in Japan, where cultural factors—such as uncertainty avoidance and social norms—may influence responses to emerging technologies.

To address this gap, a team of researchers from Juntendo University, Japan—led by Project Assistant Professor Hirohisa Fujikawa and colleagues Dr. Hirotake Mori, Dr. Yuji Nishizaki, Dr. Yuichiro Yano, and Dr. Toshio Naito—collaborated with Dr. Kayo Kondo from Durham University, United Kingdom. Together, they developed and validated a Japanese version of the scale (J-ATTARI-12) for use among medical students and resident physicians. Dr. Fujikawa explained the motivation behind the study: "We observed wide variation in how learners responded to AI, yet no validated tool existed in Japan to measure these differences. This scale helps educators understand learners' attitudes and better prepare future physicians for AI-enabled practice." The results of their study were published in Volume 12, Issue e81986 of the journal JMIR Medical Education on January 14, 2026.

The study followed internationally recognized guidelines for translation and cross-cultural adaptation to ensure linguistic accuracy and cultural relevance. A nationwide online survey was conducted between June and July 2025, recruiting medical students and residents from multiple universities and hospitals across Japan. A total of 326 participants were included in the analysis. Psychometric evaluation employed a split-half validation approach: exploratory factor analysis (EFA) was conducted on one-half of the sample to identify the underlying factor structure, and confirmatory factor analysis (CFA) was performed on the other half to assess model fit. Convergent validity was examined by correlating J-ATTARI-12 scores with attitudes toward robots—a related construct—while internal consistency reliability was assessed using Cronbach's α.

The analyses yielded several key findings. EFA identified a 2-factor structure reflecting "AI anxiety and aversion" and "AI optimism and acceptance." CFA demonstrated that this 2-factor model showed good model fit and outperformed a one-factor model. Convergent validity was supported by a moderate positive correlation between J-ATTARI-12 scores and attitudes toward robots, and internal consistency reliability was high, indicating that the scale reliably measures attitudes toward AI among Japanese medical trainees.

The study offers important educational and research implications. Dr. Fujikawa noted, "Educators can use this scale to evaluate AI-related training and identify learners who may feel uncertain or hesitant about using AI. It also allows researchers to track how attitudes evolve as AI becomes more integrated into healthcare." By providing a culturally adapted and psychometrically sound instrument, the J-ATTARI-12 supports data-driven curriculum development and informed decision-making in medical education.

Reflecting on the broader significance, Dr. Fujikawa emphasized, "The successful adoption of AI in healthcare depends on clinicians' acceptance as much as on technological performance. Making these attitudes visible enables better education and more responsible implementation." He added that the scale will be used in a "Medicine and AI" program launching at Juntendo University in 2026 and is expected to facilitate future cross-national research.

In conclusion, this study successfully developed and validated the J-ATTARI-12—the first Japanese instrument for assessing attitudes toward AI among medical students and residents. By providing a reliable and valid measure, it lays a strong foundation for advancing AI education, research, and integration within Japan's medical training systems.

History of Juntendo University

Juntendo was originally founded in 1838 as a Dutch School of Medicine at a time when Western medical education was not yet embedded as a normal part of Japanese society. With the creation of Juntendo, the founders hoped to create a place where people could come together with the shared goal of helping society through the powers of medical education and practices. Their aspirations led to the establishment of Juntendo Hospital, the first private hospital in Japan. Through the years the institution's experience and perspective as an institution of higher education and a place of clinical practice has enabled Juntendo University to play an integral role in the shaping of Japanese medical education and practices. Along the way the focus of the institution has also expanded, now consisting of nine undergraduate programs and six graduate programs, the university specializes in the fields of health science, health and sports science, nursing health care and sciences, and international liberal arts, as well as medicine. Today, Juntendo University continues to pursue innovative approaches to international level education and research with the goal of applying the results to society.

Mission Statement

The mission of Juntendo University is to strive for advances in society through education, research, and healthcare, guided by the motto "Jin – I exist as you exist" and the principle of "Fudan Zenshin - Continuously Moving Forward". The spirit of "Jin", which is the ideal of all those who gather at Juntendo University, entails being kind and considerate of others. The principle of "Fudan Zenshin" conveys the belief of the founders that education and research activities will only flourish in an environment of free competition.
