Objective:To assess the levels of self-compassion, psychological resilience, and academic adjustment of undergraduate students in a military medical university, and analyze their influencing factors and interactions.Methods:A total of 341 undergraduate students were selected by convenience and purposive sampling in a military medical university from April to May, 2022 for surveys with the General Information Questionnaire, the Chinese version of the Self-Compassion Scale, the Chinese version of the Connor-Davidson Resilience Scale, and the Academic Adjustment Scale for College Students. The collected data were analyzed through univariable analysis and multiple linear regression analysis to determine the influencing factors. AMOS 23.0 was used for path analysis.Results:The scores of self-compassion, psychological resilience, and academic adjustment of the students were at slightly high levels, with a significant positive correlation between one and another ( r s=0.580-0.611, all P<0.001). The influencing factors included professional identity, the level of received support, grade, time spent in student clubs, and the plan of postgraduate study (all P<0.05). The standardized direct effect of self-compassion on academic adjustment was 0.285 ( P=0.001), and the sum of the standardized mediating effects of psychological resilience and professional identity on self-compassion and academic adjustment was 0.314 ( P=0.001). The total mediating effect accounted for 52.42% of the total effect. Conclusions:The levels of self-compassion, psychological resilience, and academic adjustment of undergraduate students in the military medical university are influenced by multiple factors. Relevant departments should pay attention to specific populations and take targeted measures to increase the students' self-compassion, psychological resilience, and academic adjustment.
