摘要：INTRODUCTION: In social cognitive theory, self-efficacy and self-concept (SC) have been introduced as important constructs that associate with adolescents' achievements. The aim of this study was to investigate the determinant factors of academic self-efficacy (ASE) and SC in Iranian high school students based on the multilevel analysis. MATERIALS AND METHODS: In this descriptive-analytical cross-sectional study, 1740 students from 53 high schools selected with stratified random sampling method in 2018 in Qazvin, Iran. Data collection tools were the Morgan and Jinks Self-Efficacy Scale and the Piers-Harris Children's SC Scale-Second Edition. The association between some of the students and school variables with ASE and SC was analyzed by hierarchical linear regression models. RESULTS: The score of the students' standardized ASE was lower than SC. ASE and SC had a strong positive significant association with economic status, grade point average, and the educational period of high school. Sex had no association with any of them. Physical activity had a positive significant association with SC but was no found association by ASE. CONCLUSION: These findings revealed that for improving the adolescents' ASE and SC should be attention to the adolescents' family condition and school-related factors. Proper educational, sports, and supportive programs can be effective on the adolescents' self-efficacy and SC.
