Introduction. The relevance of the research problem is due to the increase in maladaptive forms of adolescents' response to various kinds of crisis situations. The importance of preventing teenage suicides has increased dramatically in the context of the socio-cultural crisis of recent decades. Despite the fact that various sciences are developing and putting into practice more and more new methods and technologies for suicide prevention, alarming trends do not disappear. A real problem of training specialists of helping professions to organize complex, specifically filled activities for diagnostic, preventive, advisory, correctional and developmental work with adolescents is being formed. The purpose of this article is to consider the possibilities of supporting the activities of specialists in helping professions to work with adolescents in the prevention of suicidal behavior. Materials and methods. The study involved 133 students and 20 teachers of general education organizations (schools of the Krasnodar Territory, Russian Federation). To carry out diagnostics on the research topic, we used theoretical and empirical methods (in particular, analysis of psychological and pedagogical literature on the research problem, testing, conversation, the method of expert assessments, the method of content analysis), as well as methods of mathematical statistics. In the course of the study, we examined the manifestations of individual characteristics of self-esteem in children, the perception of loneliness, value orientations, and features of the emotional-volitional sphere. Also, within the framework of the study, we determined the content characteristics of the construction of a comprehensive work of specialists of accompanying professions with adolescents of the "risk group". The results of the study. As a result of the diagnosis of students in grades 8-9 (133 people), a "risk group" of 14 people was identified. To confirm the criteria for inclusion of adolescents in the group of suicidal risk – anxiety, frustration, a set of diagnostic techniques was used. It was determined that 43 subjects had an average or low level of anxiety, 90 respondents (67.66%) showed an increased level of anxiety. 57.14% of respondents revealed low self-esteem, while adolescents with adequate self-esteem accounted for only 34.58%. Teenagers who were assigned to the "risk group" demonstrated a fairly high level of loneliness: 7 of 14. The results of the study allowed us to identify areas in the prevention of suicidal activity of adolescent schoolchildren, for which it is necessary to prepare specialists of accompanying professions working in an educational organization. Conclusion. Based on the data of the conducted research, it is possible to note the multifactorial etiology of suicidal manifestations, which implies the need for a comprehensive psychological and pedagogical impact on all components of this phenomenon. The age peculiarity of a teenager determines the features of his suicidal behavior, which determine the specificity and uniqueness of prevention. Preventive work on suicide prevention should be built as an integral system that includes all levels of prevention, as well as a set of measures aimed at preventing repeated attempts. At the same time, the preventive activity of suicidal behavior should integrate several areas, such as: work with family, teachers, and adolescents themselves.
