The thesis explores the adolescent process of children who have experienced early trauma. The aim is to observe whether the experience of primary emotional deficiencies leads to a failure in the structuring and psychological organisation of adolescents despite the implementation of a child protection system. Using a qualitative methodology combining non-directive interviews and projective tests (Rorschach and TAT), ten adolescents were interviewed. It was noted that drastic defences had been put in place, hindering access to the internal world and the investment of new objects. Parental imagos take a major place within the self, preventing the development of a differentiated self. The psychic conflict is woven around the relationship to the object, for lack of having been able to construct sufficiently stable internal objects, the teenagers seek in reality objects that can bring them a narcissistic repair of emotional deficiencies. However, the object provokes traumatic anxieties of invasion and abandonment and generates movements of distance that undermine any possibility of internal restoration.
