The statistical population consisted of female ninth-grade students enrolled in lower secondary schools in District 5 of Tehran during the 2024–2025 academic year. A total of 58 female students were randomly assigned to three groups: motivational interviewing (n = 19), mindset intervention (n = 19), and control (n = 20).</p> <p><strong>Findings:</strong> The results indicated that the effects of motivational interviewing and the mindset intervention differed significantly in relation to the aptitude component (p = .033) and the total academic self-efficacy score (p = .001). Specifically, the mindset intervention produced greater increases in the mean aptitude-component score and the total academic self-efficacy score than motivational interviewing. Accordingly, it was concluded that there was a significant difference between the effectiveness of motivational interviewing and the mindset intervention in improving academic self-efficacy among female secondary school students, with the mindset intervention being more effective.</p> <p><strong>Conclusion:</strong> The mindset intervention was more effective than motivational interviewing in enhancing academic self-efficacy among female secondary school students and may therefore be used as a more efficient intervention for this population.</p> https://qijes.com/index.php/ijes/article/download/1514/1497
