The article provides a fundamental analysis in the detecting of the concept of "prosocial behaviour", relying on the existing studies. It is considered as a set of personality traits that determine a person's tendency to help others and willingness to benefit others and society. The structure of prosocial behaviour distinguishes the main components of prosocial behaviour: humanistic attitudes to interaction, empathy (the ability of a person to respond emotionally to the experience of another person), moral behaviour (moral values, moral actions, personal values) and altruism (selfless activity and helping people). The level of altruism, selfishness, empathetic tendencies, prosocial tendencies of student youth, norms of prosocial orientation are recognized as diagnostic indicators of prosocial behaviour. The following research methods are used: theoretical (analysis of scientific sources, generalization of the analysed literature and its systematization, identification of basic principles that the research is based on, formulation of conclusions); empirical and statistical methods. The results of an empirical study showed that teenagers' self-esteem is dominant in comparison to adolescents', though the level of empathy among youth is proved to be much higher. It has been grounded that the empathy of adolescents, as well as teenagers, increases in situations of support and enhancement of the well-being of others, selflessness and sincerity. It has been confirmed statistically that teenagers giving assistance are characterized by the assessment of cost, loss and reward; however, adolescents are strongly exposed to a higher social responsibility rate.

The article presents the authors’ theoretical model of Self-image functioning with a peripheral part on the border of the relationship between the Self and the significant other person. An experimental study of the peculiarities of Self-image dependence is provided. The study involved 150 students of Lviv State University of Internal Affairs. Peculiarities of self-relation (dependence of the Self-image on significant other people) of students with high and moderate levels of neuroticism have been studied. The method of rapid diagnosis of neurosis (K. Heck; H. Hess), methods of self-assessment of mental states (according to H. Eysenck), author's experimental study of the "dependent" characteristic of the Self-image were used. Correlation analysis and Mann-Whitney comparative analysis were used for statistical data processing. As a result of the ascertaining experiment, it was found that the peripheral part of the Self-image of boys and girls with a high level of neuroticism (HN) is more dependent on the opinion of reference other people (unstable Self-image) than of persons with moderate neuroticism (MN) and this is accompanied by high levels of anxiety, frustration and rigidity. The hypothesis that students with a high level of neuroticism will more often depend on the opinion of significant others than students with a moderate level of neuroticism was confirmed. The studentship is a sensitive period for effective psycho-correctional influences in order to form a stable, positive and independent Self-image, and therefore, the quality use of psychological services of psycho-corrective influences can significantly affect well-being, learning and quality of life. The self-awareness of students with a high level of neuroticism should be considered both as the main object and as a fundamental support for psycho-correctional influence, and the resource of this influence should be sought in an adequate relationship.

Among the variations of anxiety disorders, generalized anxiety disorder is considered to be one of the most problematic. In times of intense social transformation, the issue of mental health of the youth, in particular the prevalence of tendencies to generalized anxiety disorder among young people arises. For this reason, the purpose of the article is to investigate the propensity of young students to excessive experiences and propose a model of understanding and treatment of generalized anxiety disorder. Cognitive-behavioral methodology is used while the study for understanding generalized anxiety disorder, PSWQ experience questionnaire, WWS-II experience value scale, and two survey items. The results of the study show that 18% of the youth surveyed have a high level of anxiety. Such young people can be considered a risk group for generalized anxiety disorder. The results of the study indicate that respondents with a high level of worry are statistically more likely to perceive worries as those helping them to solve problems, motivate them to act and are able to prevent negative results. Such positive beliefs about the experience may reduce the perceived need to seek help from psychologists and psychotherapists. A description of the clinical case is given and the effectiveness of psychotherapeutic interventions is demonstrated. An algorithm for working with clients is proposed, which is based on a modern protocol for the treatment of generalized anxiety disorder. It includes: qualified examination; reassessment of the usefulness of the worry; assistance in a realistic understanding of ambiguous situations as such that are not clearly threatening; rethinking attitudes to situations of uncertainty; use of exposures for the purpose of deeper processing of the stimulus in a nonverbal way; skills of overcoming negative emotions without avoiding them. An attempt to combine the clinical paradigm and the scientific position is made in the article. Nowadays there are very few studies based on cognitive-behavioral methodology in Ukraine.

The basic aspects of the importance of personal and semantic factors in the formation of generalized anxiety disorder are highlighted in the article. The model of understanding and psychotherapy of excessive worries, based on the reconstruction of the value system is proposed. Such reconstruction is possible due to the "rewriting" of the personal narrative, which in external manifestation functions as the equivalent of a speech act. It is through the psychosemantic aspect that the way to the field of meanings and understanding of "excessive worries" is opened and the access to the subjective world of a person in his/her own system of semantic and linguistic coordinates is provided. The cognitivebehavioral methodology of recognition of generalized anxiety disorder, Penn State Worry Questionnaire (PSWQ), WWS-II (worry scale), author's questionnaire and psychotherapeutic interventions were used, which stand for the main tool for reconstruction of semantic spaces and individual value system. The study involved 150 people aged 19-24. The results show that significant aspects of personal and semantic factors in the formation of generalized anxiety disorder can be considered as follows: client perception of worries as those that help to solve problems, motivate to action and can prevent negative results. Such positive beliefs about the worries can significantly affect the dynamics of psychotherapeutic work. The article presents a clinical case and demonstrates the effectiveness of psychotherapeutic interventions. An algorithm for dealing with clients is suggested, which is grounded on a current technique for the cure of generalized anxiety disorder and includes: qualified examination; reevaluation of the effectiveness of the worries; assistance in a realistic perception of ambiguous situations that are not necessarily threatening; reconsidering of attitudes to situations of uncertainty; use of exposures technique aimed at profound coping with the stimulus in a nonverbal way; skills of overcoming negative emotions without escaping from them. Such psychotherapy is also based on the provisions of psychosemantic analysis on the possibility of reconstructing the semantic space of algorithms of emotional-cognitive response. The article attempts to combine the clinical paradigm and the scientific position, the cognitive-behavioral model of psychotherapy and the position of psycholinguistics on cognitive processing of information on the basis of mental representations formed by the individual. The applied psycholinguistics has meaningful prospects for applied cognitive research.
