Background. The issue of Internet addiction is being actively discussed in foreign and Russian psychology in two recent decades. However, experts have not developed a common opinion on the concept of ‘Internet addiction’. Therefore different terms are used to refer to disharmonious relationships in the ‘man-Internet’ system: ‘problematic Internet use’, «’excessive Internet use’, ‘compulsive Internet use’, etc. Psychologists show more agreement in the description of symptoms of Internet addiction. Generalization of these features makes it possible to develop tools for psychological assessment of Internet addiction.

Objective is to identify the components of problematic Internet use in adolescence using the questionnaire developed by the authors of this paper, and to describe the relationship of the components of problematic Internet use with using various Internet services.

Design. Based on the analysis of the psychological literature, the symptoms of problematic Internet use were identified. The selected symptoms constituted the content of the questionnaire. Correlation and factor analysis revealed components of problematic Internet use. Relationships between problematic Internet use and using different Internet services were studied.

The sample of the study consisted of 150 people aged 16 to 23 years: 64 high school students and 86 university undergraduates. The data was collected throughout the period from October, 2017 to November, 2017.

Results. The study of symptoms and manifestations of problematic Internet use in high school students and university students allowed to develop a scale of problematic Internet use bringing together five components (super-value of Internet activity, frustration of vital needs, anticipation of accessing the Internet, reducing monitoring time and reducing the significance of events outside the network). The features of using Internet services depending on gender and age are described. Correlations of problematic Internet use with types of activity in a network are established. The most closely components of problematic Internet use are connected with use of communicative (social) services.

Conclusion. The study of problematic Internet use and its components allows us to offer a five-component model of problematic Internet use and describe the relationship of problematic Internet use with Internet services and applications using.

Introduction Informational socializing of modern adolescents influences the form of communication as the main source of development and self-determination as the major developmental factor in adolescence. The investigation of links between personal features and moral values and Internet involvement allows defining the problem of correlations between personal and cognitive component of development and prevent cyberbulling and communication on-line risks.

The Objective of the study is to investigate the correlation between basic attitude and moral values of adolescents and the productivity of cognitive processing of social information on the Internet. The hypothesis of the study is the assumption that adolescents with a positive attitude to the mediated world and a high level of moral values reveal greater productivity of cognitive methods of processing social information obtained on the Internet. One of the goals of the research was to identify the relationship between basic beliefs and the Internet addiction in adolescents.

Methods and sampling. The study used the following methods: 1. Basic Belief Scale by R. Yanoff-Bulman (Kalmykova, Padun, 2002); 2. Methods of diagnosing moral values "Fair-Care" (S. Molchanov, A. Podolsky); 3) the author's method of cognitive assessment of social information on the Internet, based on the Crick and Dodge model (Crick, Dodge, 1994); 4. Method of diagnosing Internet-dependent behavior by S.H.Chen. The population aged 13 to 18 years accounted 175 adolescents (49% males and (51% females).

Results. Three groups of adolescents were different in the nature of basic assumptions and the level of development of moral values optimists, pessimists, and ego-centered pessimists, and Internet addicted. Comparative analysis of the cognitive methods of processing social information on the Internet, as well as signs of Internet addiction was carried out.

Conclusions: The hypothesis that positive attitude to the mediated world and belief that they control life, a high level of moral values associated with more productive cognitive methods of processing social information on the Internet has received confirmation. A group of adolescents identified as “pessimists” (perception of the world as hostile, negative image of themselves, lack of confidence in the world and success, low level of moral values) reveal signs of Internet addiction in behaviour.

The paper presents the social problems of Internet addiction.

One of the primary causes of Internet addiction is a rapid increase in using modern Information Technology. Obvious changes in psychological traits of persons who deal with the computer and turning it into an object of psychological research are analysed. On the one hand, the Internet is viewed as one of the issues of the man’s trouble, on the other hand, the Internet contributes to the solution of many problems of modern man.
