Objectives

Narrative objectives1

The purpose of this study is to clarify the psychological and physiological effects of medical interviews conducted via an interactive robot avatar on both patients and physicians.This exploratory study aims to examine how avatar-mediated interviews, compared with conventional face-to-face physician interviews, influence patients'psychological burden, physicians' stress responses, the quality of communication, and mutual understanding.

Developmental phase



Assessment

Primary outcomes

The primary outcome is the change in psychological stress levels of patients and physicians before and after each interview, evaluated by the change in mood and emotional state measured using the Profile of Mood States, Second Edition (POMS2), and compared between the physician-mediated and avatar-mediated interview conditions.

Key secondary outcomes

Patient and physician satisfaction, psychological burden, and level of understanding will be evaluated before and after each interview.
During each interview, physiological parameters such as heart rate variability, voice features, and emotion indicators derived from facial expression analysis will be measured.
Furthermore, plasma metabolites and hormones, as well as multi-omics analyses of peripheral blood mononuclear cells (PBMCs)-including gene expression and metabolic profiles, obtained from blood samples collected before and after each interview will be compared between the physician-mediated and avatar-mediated interview conditions.

Interventions/Control_1

Each patient will undergo two interviews one is a standard medical interview conducted by a physician and the other is an interview conducted via an interactive robot avatar. During the avatar-mediated interview the physician will remotely control the avatar either fully or partially. Each interview will last approximately 30 to 60 minutes. The conversation mainly consists of questions about the patients symptoms and physical condition as well as discussions regarding concerns or questions about their disease or treatment. This study adopts a within-subject self-controlled randomized crossover design.The first interview will be conducted by a physician, and the second interview will be conducted via an avatar.

Interventions/Control_2
