The aim of this study is to examine the relationship between primary school student‟s behavior problems and family functionings in early puberty. The sampling of the study consists of 389 adolescent students attending 6th, 7th and 8th grades. The data of the study was collected via using Youth Self Reported /11-18 and Family Assessment Device. The data was analyzed with the help of Pearson‟s Correlation of Coefficient technique. As a result, a quite positive relation between adolescents‟ behavioral problems and family functionings was found and it was determined that as the family functionings became maladaptive, behavior problems tended to increase. In this sense, this study underlines the importance of family, which can carry out their family functions completely, bringing up of adolescents healthily. It is suggested that further studies should make use of different age groups from the point of such an analytic concept.
