Personality, peers, and professional values are predicted to enhance caring behavior. This study aims to determine the relationship of personality, peers, and professional values with caring behavior in nursing students. The research design was cross-sectional and involved 126 nursing students from two nursing education institutions in the 5th region of the Association of Indonesian Nurse Education Center (AINEC), which were selected by consecutive sampling. The findings of the study indicated a moderate and positive relationship between personality, the caring behavior of peers, and professional values of nursing with the caring behavior of nursing students (p < 0.001; r respectively 0.483, 0.567, and 0.742). The analysis revealed that a caring personality contributed 22.7%, peer caring behavior 31.7%, and professional values 54.7% in shaping students' caring behavior. The researcher proffers recommendations for courses or programs that have the potential to fortify the caring personality and professional values of nursing, in addition to the establishment of caring groups and the cultivation of peer caring behavior within professional contexts.
