Background: A number of the QL researches in case of different pathologies are being increased during the last decade. The existing traditional research methods provide mostly arbitrary data on the disease and its treatment, which are not sufficient for the schoolchildren overall psychological and social adaptation and wellness evaluation. Methods: The research object became schoolchildren of 3 randomly selected schools in Yerevan. 443 monitoring units formed the selection population. The degree of situational and personal anxiety was evaluated with the help of Spielberger's and Gerbachevski's tests. Results: According to our research data the anxiety degree was 29,2 ± 2,3 points among the girls and 12,5 ± 1,6 points among the boys, respectively. The individual anxiety level was especially high: it made up 44,5 ± 0,8 points, and that of the situational anxiety made up 37,2 ± 0,5 points (p < 0,05). According to Gerbachovski's test in the group of schoolchildren with ENT pathology those with a high level of demands made up 53,5 ± 3,2%, with a medium level of demands -32,4 ± 3,0% and with a low level of demands −14,1 ± 2,2%. A number of the practically healthy schoolchildren with a low level of demands made up 50,3%, and with a high level -30,7%. Conclusion: According to the investigation data those children who suffer from the ENT chronic diseases usually avoided communication, were sluggish and shy. According to the results of the research, the socio-psychological and adaptation abilities of children with the ENT chronic diseases were lower than those of the practically healthy (without ENT pathologies) coevals. This fact urges to improve the prophylactic measures provision in the mentioned pathologies aspect.
