Participants were selected through stratified random sampling based on the Morgan and Krejcie table. Standardized instruments were used to measure peer support (Child and Adolescent Social Support Scale), academic self-efficacy (Patterns of Adaptive Learning Scales), and intrinsic motivation (Academic Motivation Scale). Data were analyzed using SPSS-27 for descriptive statistics and Pearson correlations, and AMOS-21 for Structural Equation Modeling (SEM). Model fit was assessed using indices such as χ²/df, GFI, CFI, TLI, and RMSEA.</p> <p><strong>Findings: </strong>Descriptive results indicated high mean levels for intrinsic motivation (M = 5.03, SD = 0.63), peer support (M = 4.82, SD = 0.68), and academic self-efficacy (M = 4.57, SD = 0.74). Pearson correlation analysis revealed significant positive relationships between peer support and academic self-efficacy (r = .46, p &lt; .01), peer support and intrinsic motivation (r = .39, p &lt; .01), and academic self-efficacy and intrinsic motivation (r = .51, p &lt; .01). The SEM showed acceptable fit indices (χ²/df = 2.00, CFI = 0.96, RMSEA = 0.048). Academic self-efficacy partially mediated the relationship between peer support and intrinsic motivation. The total effect of peer support on intrinsic motivation was β = .47 (p &lt; .001), with a direct effect of β = .28 and an indirect effect of β = .19 through academic self-efficacy.</p> <p><strong>Conclusion: </strong>Findings highlight the dual role of peer support—both direct and mediated by academic self-efficacy—in enhancing intrinsic motivation among dyslexic students, suggesting the importance of fostering supportive peer environments and self-belief in inclusive educational settings.</p> https://qijes.com/index.php/ijes/article/download/1321/1404
