The statistical population consisted of all ninth-grade male students in District 5 of Tehran in 2024. Using convenience sampling, 30 eligible students were selected and randomly assigned to either the experimental group (n = 15) or the control group (n = 15). Research instruments included the Self-Control Scale developed by Tangney et al. and the Adjustment Scale by Sinha and Singh. The experimental group received eight 90-minute reality therapy sessions over four weeks, while the control group received no intervention. Data were analyzed using multivariate analysis of covariance (MANCOVA) with SPSS version 22.<br> <b>Results</b>: Findings indicated a significant difference between the experimental and control groups in post-test self-control scores. In other words, reality therapy had a positive effect on improving adolescents&rsquo; self-control (p < 0.001).<br> <b>Conclusions</b>: Reality therapy can effectively enhance self-control among adolescents. School counselors may employ reality therapy sessions or workshops as an efficient intervention to improve self-control and adjustment in adolescents.</span></span></span></span></div> Reality Therapy, Self-control, Adjustment, Adolescents 0 0 http://ijer.hormozgan.ac.ir/browse.php?a_code=A-10-372-1&slc_lang=en&sid=1 Elaheh Sedqi Khalifani elahesedqii@gmail.com 10031947532846003902 10031947532846003902 No BA in General Psychology, Urmia Branch, Islamic Azad University, Urmia, Iran Majid Abasi Psy.majid66@gmail.com 10031947532846003903 10031947532846003903 Yes Department of Psychology, Faculty of Humanities, Arak Branch, Islamic Azad University, Arak, Iran Vahid Sammehr Vahidsam75@yahoo.com 10031947532846003904 10031947532846003904 No PhD student in Psychology, Urmia Branch, Islamic Azad University, Urmia, Iran Nahid Rastinpoor nahidrastin222@gmail.com 10031947532846003905 10031947532846003905 No BA in Counseling, Dezful Branch, Islamic Azad University, Dezful, Iran Fareme Ghazi Asgar Fatimaghaziasgar79@gmail.com 10031947532846003906 10031947532846003906 No MA in School Counseling, Shahid Beheshti University, Tehran, Iran
