The article presents a research with 30 juvenile people living in residential communities and with four significant others for each of them: the father, the mother, a brother or sister and a teacher or employer. This sample is compared with a group of control similar in extension, age and socio-cultural characteristics. The total number of the subjects involved is 300. Using Kelly’s repertory grids a special method to measure interpersonal distances is proposed. In this way some relational indexes (acceptance, identification, similarity, predictive accuracy, etc.) are obtained and used to enlighten some characteristics of the construing of a deviant identity. Then self is always considered in relation to the interpersonal contexts within which it is construed and maintained.
