Introduction: Psychopathy is a multidimensional personality disorder that has attracted a lot of attention in the clinical fields. In this research, the validity of the Persian version of the Long Form of Youth Psychopathic traits Inventory (YPI) and the evaluation of its psychometric indicators are considered.Method: The method was descriptive-analytical and exploratory. The sample consisted of 557 male youths living in Tehran and Golestan provinces in the academic year of 2021-2022, who were selected by available sampling method and completed Youth Psychopathic traits Inventory and Questionnaire of Cognitive and Affective Empathy (QCAE). The psychometric properties were analyzed by confirmatory factor analysis, divergent validity, Pearson's correlation and Cronbach's alpha coefficient.Findings: The results of the confirmatory factor analysis indicated the existence of three interpersonal, affective and behavioral factors and indicated the good fit of the obtained model (p<0/001). The significant correlation between the Questionnaire of Cognitive and Affective Empathy and the Youth Psychopathic traits Inventory confirms the divergent validity of this tool (p<0/01). The validity of the scale was found to be acceptable by calculating the Cronbach's alpha coefficient and the composite reliability of the factors. The reliability results of this tool through the retest method showed a high correlation between the two implementations (p<0/01).Conclusion: In general, the Persian version of the Long Form of Youth Psychopathic traits Inventory (YPI) and its three-factor structure were confirmed, and it can be used in psychological researches with appropriate validity and reliability.
