摘要：The aim of the study is twofold. On the one hand it concerns the measurement and the examination of the subjects’ self-concept and on the other the detection and justification of the role of family in its configuration. The study analyzed the data collected from the answers to a research questionnaire of 1344 15-and 16-year-old school students in the Prefecture of Thessaloniki, Greece) with the use of a stratified random sampling technique. The first important finding concerned the high degree of the general self-concept of the adolescents. Among the seven specific sectors of the general self-concept a major variation was noted, with the higher average to be traced in the relationship that the students have configured with their peers and the lower one in the valuation of their academic competence. The second important finding was the ascertainment of the essential contribution of the family.
