The existing models of suicidal behavior (model of the development of suicidal behavior in adolescents; interpersonal model (T. Joiner), cognitive theory of suicidal behavior (A. Beck), integrative model of suicidal behavior (D. Wasserman), model of “stress diathesis” (J. Mann), psychodynamic (K. Menninger) and motivational-phenomenological models
(E. Shneidman)) indicate the need to study the differences between long-and short-term factors of suicidal risk. Traditional factors of suicidal risks such as psychiatric disorders, specifics of personal development, familial and social factors, personality traits, medical and psychodynamic factors (hopelessness, bereavement), suicide attempts and genetic factors are fairly well studied and characterized. They are good predictors of suicidal activity and completed suicide in long-term but can’t be used for predicting short-term risk.

Therefore, several models of suicidal behavior emergednow that have focused on assessing the dynamics of the suicidal process and acute suicidal states, including the search for biomarkers of suicidal risk.
