Self-Concept and Its Impact on Academic Performance Among High School Students

Background: Academic self-concept is a critical determinant of student performance, yet its influence on academic achievement remains underexplored in developing educational contexts. Prior research highlights a strong association between self-concept and academic success, but gender-based differences and predictive relationships remain inconclusive. Objective: This study aims to examine the relationship between academic self-concept and academic performance among high school students while analyzing gender-based differences in self-concept, confidence, and effort as predictors of academic achievement. Methods: A cross-sectional observational study was conducted among 250 public high school students (115 boys, 135 girls) aged 13–19 years in Rawalpindi, Pakistan. Participants were selected through convenient non-probability sampling. Academic self-concept was assessed using the Revised Academic Self-Concept Scale, and academic performance was measured using the Academic Self-Description Questionnaire. Ethical approval was obtained from Fatima Jinnah Women University IRB (following the Helsinki Declaration. Statistical analysis, including Pearson correlation, independent t-tests, and multiple regression, was conducted using SPSS v20. Results: Academic self-concept showed a strong positive correlation with academic performance (r = .658, p < 0.05), with academic confidence (β = 0.42, p < 0.001) and effort (β = 0.28, p = 0.00) emerging as significant predictors. Boys demonstrated higher academic self-concept (M = 90.35, SD = 7.42) and confidence (M = 29.31, SD = 7.03), whereas girls exhibited greater academic effort (M = 45.89, SD = 6.42, p = 0.001). Conclusion: Academic self-concept significantly predicts academic performance, emphasizing the need for interventions fostering self-confidence and effort-based learning. Addressing gender disparities in self-perception can enhance student outcomes and inform educational policy improvements.
