The relevance of the research is determined by the fact that in recent decades, the issue of human health is one of the priority areas of scientific knowledge and is the focus of comprehensive study. Health is considered a complex, multi-level phenomenon that determines the reproductive and creative capabilities of both individual subjects and entire communities. However, it must be recognized that many important aspects of human health today require additional research. Former concepts give a limited interpretation of the phenomenon of health, reducing the variety of its manifestations to biological or psychophysiological models. Accordingly, such approaches do not correspond to the current level of natural and humanitarian knowledge about man.
The article presents the results of a study that was conducted before the start of a full-scale war in Ukraine. It was implemented by a group of authors on the basis of Lesya Ukrainka Volyn National University and included 56 students, aged 17…18, who are studying in various educational programs. The obtained results showed that the majority of the studied young people experience subjective well-being (high level – 31%, average – 41%) and a normal level of quality of life (85%), which are important indicators of the manifestation of their mental health. It was possible to identify additional characteristics of young people, such as a normal level of satisfaction with everyday activities, high self-esteem of health, and the importance of the social environment. They became assumptions that establishing social ties, effective interaction and communication, self-development, and self-realization are important for the studied youth. So, the research results showed that before the war, the young people we studied had a positive attitude to life: they set goals for themselves, made plans for the future, showed high social activity, and were satisfied with their lives.
Key words: mental health, criteria of mental health, subjective well-being, quality of life, harmonious development, self-regulation, self-realization.
