Background and Objective: Adolescence is a critical period of psychological, physical, and social development, accompanied by cognitive and emotional changes that can affect self-control and distress tolerance. This study aimed to examine the effectiveness of spiritual intelligence training in improving self-control and distress tolerance among students. Materials and Methods: The present study employed a quasi-experimental design with a pretest–posttest and a control group. The statistical population included tenth-grade female students in Hamadan during the 1404–1403 academic year. Thirty students were selected using a convenience sampling method and randomly assigned to experimental and control groups (15 per group). The experimental group received eight 60-minute sessions of spiritual intelligence training, while the control group received no intervention. Data were collected using self-control and emotional distress tolerance questionnaires and analyzed using analysis of covariance (ANCOVA). Results: The findings indicated that spiritual intelligence training had a significant positive effect on self-control and distress tolerance in the experimental group compared with the control group (P < 0.01). Conclusion: Spiritual intelligence training can be an effective approach for enhancing students’ emotional skills and psychological adaptation.
