Introduction: Perfectionism is a psychological issue that psychologists have studied extensively. Research shows that perfectionism can either enhance or hinder performance. Aim: The purpose of this research was to develop a model of perfectionism for abnormal personality traits. Method: This study utilized a mixed exploratory approach, combining qualitative and quantitative methods. The qualitative phase involved 20 university experts knowledgeable about perfectionism in sports, with the sample size reaching theoretical saturation. The quantitative phase included 232 players from the national team's training camps, selected through convenience sampling. Using the onion research method, a model of perfectionism for abnormal personality traits in national team players was developed based on interviews and expert input. A 10-component questionnaire was created from this model. Structural equation modeling and Smart PLS software were used to test relationships within the model. Results: The research yielded a model of perfectionism for abnormal personality traits in national team players, consisting of components such as negativity, expectations of others, coach criticism, self-control, individual standards, positivism, striving for excellence, fear of failure, and performance doubts. Conclusion: The results suggest that perfectionism significantly influences players' attitudes and behaviors, particularly in relation to abnormal personality traits.
