Topicality of the study of the connection between the emotional component of family’s informational environment and the propensity for disadaptive behaviour of adolescents is determined by the tendency to increase the role of the information environment in society, in particular in the family. The study of the emotional component of the informational family environment and its connection with disadaptive behaviour of adolescents involved 70 people, representing 35 teen-parent dyads. The authors' method "Information environment of the family" and the method of determining the propensity to deviate behaviour of El'vira Leus were used. In 40% of cases, the family information environment is represented by the unity in the experience of adolescents and parents of interest and excitement while using gadgets. Their experience of joy, surprise and sadness reveals their individual differences in interaction with the family information environment. The tendency to deviant behaviour was considered to be the main indicator of the socio-psychological disadaptation of adolescents. All the 35 adolescents showed varying degrees of disadaptation. A connection was found in the experience of joy on the Internet with a tendency to addictive, aggressive and unlawful behaviour. The results can be used in the work of the school psychological service, as well as in psychotherapy of adolescents and families.
