This study investigated the relationships of situational factors, motivational assessment-related factors, and situationally induced personal characteristics with pro-social intention to disclose patient information among health and medical students. In total, 210 students from Konyang University participated in the survey, including 116 medical students and 94 other health students. To measure the influence of variables on pro-social intention to disclose information related to health information security, a 27-item questionnaire was used. The reliability of the survey was shown by Cronbach's α values of 0.859 to 0.917. According to students' perceptions, higher disease severity was significantly related to higher impacts on the patient, family, and themselves (p<0.01), as well as higher situational empathy (p<0.05). Pro-social intention to disclose showed negative correlations with health information security awareness, information education experience, perceived impact on the self, responsibility to disclose, and personal norms (r=-0.136 to -0.647, p<0.05). Responsibility to disclose and situational empathy explained approximately 44% of the variance in pro-social intention to disclose. Additionally, students who received information security training perceived a significantly higher responsibility to disclose, exhibited higher health information security awareness, and had lower pro-social intention to disclose. This study confirmed the need for information security education for health and medical students, and suggested that pro-social characteristics such as empathy and responsibility need to be carefully addressed in information security education.
