Background. The digitalization of society is making changes in the lifestyle of the whole population today. However, while the older generation uses the Internet as a tool, the teenagers, youth, and young adults perceive it to be a full-fledged living environment. Today, Internet resources are the main way of involving young people in extremist groups, and radicalizing them. The role of the Internet as a means of socialization is actively discussed in scientific discourse, and questions about the prevention of the negative impact of the Internet environment are being raised, as well as about the technologies and mechanisms used for exerting extremist influence. However, it is important to understand that the features of the sense of identity of the recipient are essential for the formation of sensitivity to Internet exposure, including to extremism.

Objective. The aim of our study was to identify personal predictors of the involvement of teenagers, youth, and young adults with the Internet, as well as to analyze their personality traits and vulnerabilities for extremist influence via the Internet.

Design. Our research methods included a sociological questionnaire for analyzing the involvement of respondents in the Internet environment, and adaptations of the psycho-diagnostic methods HEXACO, “The Dark Triad,” and a modified projective technique “Houses.” Our study sample was comprised of 2051 people (528 teenagers 13-15 years old, 686 youth 16-20 years old, and 836 young adults 21-29 years old).

Results. The results of the study showed that 16.9% of respondents are characterized by maximum involvement and immersion in the digital environment. Compared with the contrasting group of respondents who are less actively immersed in the Internet environment, the “involved teenagers, youth, and young adults” are characterized by a stable complex of personal characteristics (narcissism, “Machiavellianism,” inability to forgive, lack of organization, negative mood patterns, etc.). Also, behavioral markers and zones of vulnerability are defined for respondents who are characterized by maximum involvement and immersion in the digital environment while experiencing extremist influence on them.

Conclusion: The identified personal characteristics of teenagers, youth, and young adults actively involved in the Internet environment allow us to define and specify measures to prevent the radicalization of this group.
