Objective: exploring the impact of emotional and personal well-being on the attitudes of security sector professionals towards other people, both those within their communication zone and those outside it. Methods: (1) Semantic differential technique (SD), where descriptors were represented by 24 personal qualities in terms of which the respondents were asked to evaluate two SD objects: people within their social circle, and those outside it; (2) Emotional-personal well-being self-evaluation technique (EPWBSE), where the respondents evaluate themselves in nine mono-scales. The research sample consisted of 2,229 people from different professional categories, including 298 representatives from the power block (98 people from the Russian Ministry of Defence (MoD) and 200 respondents from the Russian Ministry of Internal Affairs (MIA)). Conclusions: It was found that representatives of the Ministry of Internal Affairs demonstrated more positive attitudes towards people from the communication sector, while representatives of the MoI showed more positive attitudes towards people in general. In the MIA sample, emotional-personal well-being is significantly higher and, at the same time, it is related to the dynamics of social perception: the higher the level of emotional-personal well-being, the more positively people in the communication zone are perceived, while the lower the SELB level, the more positively people, in general, are perceived. Trends in social perception in MD representatives can be preconditioned by other factors. Further to the conducted analysis, it is planned to study different-level determinants of social perception in representatives of different security services.
