The review is devoted to the hardiness of the individual as a factor of specifi c protection, potentially capable of reducing the risk of developing suicidal behavior. The development of the concept of “hardiness” and the features of its application in the subject field of suicidology are considered. ”Hardiness” is understood as a key personality variable that mediates the infl uence of stressful factors (including chronic ones) on somatic and mental health, as well as on the success of an activity. It is hardiness that allows a person to endure the fatal anxiety that accompanies the choice of the future (uncertainty), and not the past (immutability) in a situation of existential dilemma. The source base of the study was 38 publications. High agreement was noted between the authors that hardiness is an important protective factor for the emergence of suicidal ideations, performs a buff er (antisuicidal) role in a situation of distress, and is part of the normative functions of the human adaptation system. The signifi - cance of the contribution of certain parameters of hardiness to the protection of anti-vital and suicidal behavior can vary individually and socioculturally. The linear nature of the infl uence of the components of the phenomenon of hardiness on the likelihood of anti-vital and suicidal behavior seems relative.

Significant for the development of suicide prevention measures are evidence that suicidal risk is associated with a weakening of reserves of hardiness, and a decrease in this risk is possible by strengthening the potential of hardiness through targeted psychosocial interventions. The potential variability of the parameter “hardiness” allows us to consider it as an important target for the prevention of suicide.
