Background and Purpose: The present study was conducted with the aim of explaining the structural pattern of the relationship between primary maladaptive schemas and self-injurious behaviors in students: the mediating role of distress tolerance. Research method: The method of descriptive correlational research was structural equation modeling. The studied population in this research was all the students of the second period secondary schools of Bukan city in the academic year of 2022-2023. A sample of 370 people was selected using the multi-stage cluster sampling method. To collect data, Yang (2003) early maladaptive schema questionnaires, Sanson et al.'s (1998) and Simmons and Gaher's (2005) distress tolerance scale were used. For data analysis, Pearson correlation method and structural equation modeling and statistical software spss (version 25) and Amos (version 25) were used. Findings: The findings of the research showed that the schema of cutting, self-directedness, directionality, limitation, and listening to the bell on self-injurious behaviors both directly and indirectly with the mediator role of distress tolerance have the ability to predict self-injurious behaviors.
