Abstract: Objective To investigate the effects of self-career management on college students' learning burnout under the mediating role of problematic social media use. Methods Using the individual career management scale,problematic mobile social media use assessment questionnaire and adolescent learning burnout scale,a cross-sectional survey was conducted to distribute questionnaires to 13 018 college students in a certain university in Baoji City,Shaanxi Province in November 2023. 13018 questionnaires were collected on November 10,and 5 000 were randomly selected for data analysis. Results There were statistically significant differences in self-career management among students from different family residences and parents with the highest education level（both P<0.05）,with urban students[（38.65±5.87）points] scoring higher than rural students[（38.19±5.56）points]. There were statistically significant differences in learning burnout among students of different genders and parents with the highest education level（both P<0.05）,with male students[（46.29±8.78）points] scoring higher than female students [（44.08±8.35）points]. There was a statistically significant difference in the scores of problematic social media use among students of different genders（P<0.05）,with boys scoring[（61.13±10.36） points] higher than girls[（60.32±10.41）points]. There was a correlation between problematic social media use,self-career management,learning burnout,and their respective factors（P<0.01）. Self-career management significantly negatively predicted learning burnout（β=-0.106,R²=0.011,F=56.950,P<0.01）,self-career management significantly positively predicted problematic social media use（β=0.165,R²=0.027,F=140.426,P<0.01）,and self-career management and problematic social media use jointly predicted learning burnout（R²=0.163,F=489.512,P<0.01）. Therefore,in the impact of self-career management on learning burnout,problematic social media use played a mediating role. Conclusion Self-career management can significantly negatively predict learning burnout,and indirectly affect learning burnout through the mediating effect of problematic social media use. Through corresponding psychological courses and activities,students can be promoted to form good living habits,strengthen their career management abilities,and alleviate the degree of learningburnout.
