Introduction. Based on empirical research, the author makes a qualitative analysis of the relationship between students' leadership qualities and interpersonal conflicts as well as discusses the features of student intrapersonal conflicts and their relationship with students' leadership potential. Aim. To explore the relationship between the humanities and engineering students' leadership qualities and intrapersonal conflicts. Methods. The study of the impact of intrapersonal conflicts on the development of humanities and engineering students' leadership qualities was conducted using the Lauterbach Intrapersonal Conflicts questionnaire. Results. According to the structure of leadership qualities proposed by the author, intrapersonal conflicts are a personal leadership potential development factor, which is a personal psychological characteristic. The author discusses in detail four types of intrapersonal conflicts (the conflicts between the needs for dominance and subordination, the conflicts between the need for achievement and the fear of failure, the aspirations-and-achievements conflicts, and the trust-and-self-sufficiency conflicts), which affect the development of the humanities and engineering students’ leadership potential. Conclusions. Intrapersonal conflicts indicate the presence of contradictions between the individuals' leadership qualities such as purposefulness, motivation, integrity, confidence, developed personality, and adequate self-esteem. Intrapersonal conflicts can both promote individuals' leadership skills and decrease them. Therefore, further research into personal leadership skills development is necessary to create developmental and training methods to control intrapersonal conflicts, which could help students in their future careers.
