[The meaning of health evaluation and its assessment in forming healthy behaviors of children and young people].

Healthy behaviour of children and adolescents and their determinants are subject of many research studies in modern psychology and health pedagogy. The most frequently mentioned predictors are: a sense of self-efficacy, coping with stress, optimism and health locus of control. The aim of the conducted study was to try and answer whether such variables as value of health and subjective valuation of own health can be predictors of children and adolescents' health behaviours. The article shows the results of the research on 903 students of primary schools, high schools and secondary schools. The following methods were used: the Juczyński Health Behaviours Inventory, the Juczyński Personal Value Scale (LWO) and VAS scale. The results indicated significant influence of the value of health and its valuation on taking up health behaviours of the researched group. The examined children and adolescents who highly value health take up more wellness behaviours. Those who consider their health to be in a very good condition avoid behaviours and places threatening health, are more active physically and take up health practices more often.
