The statistical population included all students studying at Farhangian University in Birjand at Imam Sajjad and Shahid Bahonar campuses in the academic year 2016-2017, totaling 1,950 individuals. The research sample included 40 students from Farhangian University who voluntarily enrolled and were randomly assigned to two groups of 20 each using a random numbers table. The experimental group participated in 12 sessions of 90 minutes each, one session per week over two months, undergoing an intervention program based on self-determination skills developed by the researchers based on Deci and Ryan's (1985) self-determination theory. The control group received no training during this period. The Jones and Rhodewalt (1982) Self-Handicapping Scale and the Solomon and Rothblum (1984) Academic Procrastination Scale were used to measure the variables. Data analysis was conducted using SPSS-23 software.</p> <p><strong>Findings:</strong> The results of multivariate covariance analysis indicated that self-determination skills training had a significant effect on reducing student self-handicapping (F=104.88) and academic procrastination (F=34.74) (p&lt;0.001), and these results persisted in the follow-up phase.</p> </td> </tr> </tbody> </table> <p><strong>Conclusion:</strong> Based on the findings, learning and applying self-determination skills by students can reduce self-handicapping and the occurrence of procrastination behaviors during their studies. Therefore, the results of this study have practical implications for psychologists and counselors at university counseling centers to utilize self-determination skills to reduce academic procrastination and self-handicapping among students.</p> https://journals.kmanpub.com/index.php/jayps/article/download/1878/4315
