Medically unexplained chronic pain - without identifiable somatic origin - is yet an insufficiently known and explored field in children and adolescents by international clinical works. This research aims to characterize somatic, psychological, psychopathological and environmental (particularly attachment styles and family functioning) processes trough an observational study with three pain management centers.

The study concerns children and adolescents from 7 to 17 years old, suffering of medically unexplained chronic pain and their parents who are referred to a pain center. It is composed of a somatic, psychological and family functioning assessment on the one hand and psychopathological and attachment evaluation on the other hand.
