Clinical-psychological and socio-demographic features of suicidal behavior of the population of Minsk (Republic of Belarus)

Background. Currently, the search for reliable indicators of the risk of committing suicide remains relevant, which makes important the study of causes and conditions of the occurrence of suicidal behavior. Objective: to determine statistically significant clinical and psychological factors and socio-demographic characteristics associated with severe motivation to commit suicide. Material and Methods. Based on the data of 10-year monitoring of suicidal behavior of Minsk residents, two groups of individuals with suicide risk are formed from the main group of respondents: 1) a group of persons who have used non-lethal methods of self-harm (conditionally called GPUNS), 2) a group of persons who have used highly lethal methods of self-harm (GPUHS). The comparison group includes persons who have the diagnosis of adjustment disorder (ICD-10 code F43.2), who have not previously committed suicide attempts. Significance for binary indicators is assessed by the Pearson criterion (x2), for quantitative indicators by the Kruskal-Wallis test (H), intergroup differences are assessed by the Mann-Whitney test (U). The relationship between socio-psychological factors and the motivation to commit suicide is determined with the Spearman's correlation coefficient (r) using the Python programming language. Results. The most pronounced factor interrelated with the severe motivation to commit suicide has been the way of committing suicide (rFN-0.68). It is found that the borderline significance level (rD=0.28) has two factors: 1) the factor of the presence of mental disorders due to alcohol use in men, in women - presence of depression spectrum disorders; 2) the education factor (rD=0.28). Persons from suicide risk groups (GPUHS and GPUNS), are characterized by upbringing in a one-parent family, living alone or in one-parent families, and having a secondary or secondary special education. In GPUHS group, certain personality traits are revealed (excitability in men and cyclothymia in women). Conclusions. The most significant factor associated with severe motivation to commit suicide is the method of suicidal actions. The factor of the presence of the diagnosis of mental disorder and the factor of education are on the border of statistical significance. Social living conditions and individual personality traits are significant factors for suicide risk groups, but are not interrelated with severe motivation to commit suicide.
