Abstract: the article examines the role of the Internet environment and social networks in the life of modern teenagers, their impact on the psycho-emotional sphere and social development in general.

Statistical characteristics were extracted from more than 210 thousand publications of adolescent Vkontakte users. The authors pay special attention to identifying correlations between individual markers of anxiety-depressive states of adolescents and values on the scales of the methods used in the study: the Beck Depression Inventory (BDI) adolescent version, the Zung Self-Rating Depression Scale, the Russian-language adaptation of T. Balashova, the Spielberger anxiety scale (State-Trait Anxiety Inventory, STAI) Russian-language adaptation by Yu.Khanin.
