From 2014 to the present, Ukrainian military personnel have been fighting in Eastern Ukraine against illegal armed formations of separatists. The resulting combat stress negatively affects servicemen’s mental health status. This study aimed to examine the factor structure of a scale to assess the psychological safety of a soldier’s personality (PSSP), taking into account changes in the conditions of military service to improve the professional and psychological training of military personnel.

Material and methods:
The study involved 118 officers of the National Guard of Ukraine. The semantic differential method, expert judgment, and exploratory factor analysis were used to determine the factor structure of the PSSP.

The PSSP model to maintain combat readiness in daily activities includes four components: “Moral and communicative”, “Motivational and volitional”, “Value and meaning of life” and “Inner comfort”. For activities in extreme conditions (during combat deployment), the personality potential of four structural components is used: “Moral and volitional regulation”, “Coping strategies”, “Value and meaning of life” and “Post-traumatic growth/regression”.

The PSSP model consists of four components that have different content depending on the conditions for performance of professional tasks by military personnel. It is advisable to use the obtained results of the content of the PSSP model in the development of professional and psychological training programs for the purposeful formation of the resilience of military personnel, taking into account the conditions of their activities.
