Due to the growing interest in the phenomenon of self-efficacy, the psychological science examines the directions of studying self-efficacy in domestic and foreign exploratory development. The attention is focused on studies that reveal the interrelation of the self-efficacy phenomenon with other psychological phenomena, such as motivation to succeed and avoidance of failure, as well as studies devoted to the features of self-efficacy ideas in male and female students. There are publications on the data of the empiric investigation of interrelation of self-efficacy and success motivation in young people at various university training stages with presentations of analysis of differences in correlation features in male and female students. A conclusion is made that there are differences existing between the investigated indicators of self-efficacy in substantive work, self-efficacy in interpersonal communication and success motivation in the first-year and the second-year students, as well as the differences existing in the outlined indicators in the young people taking university psychological and legal courses.
