This paper is an analytical description of the mental health system set up by Handicap International in the Palestinian camps in Lebanon. The main characteristic of this system is to associate an ecological perspective (concerned with the environment of the people) with an individual perspective (concerned with the resources of the persons) to restore the social participation of children living with various types of disabilities (intellectual or psychosocial). Through these two perspectives, the mental health professionals try to maintain a form of collective therapeutic solidarity whereas the beneficiaries of the intervention are not so much regarded as autonomous and abstract but as interdependent and concrete. Child care takes account of the caregiving resources of his or her community. By collectively planning out their interventions with the families and the key resource people of the community, the mental health professionals work on the question of their interdependencies. This results in a health care system that ceases to be the place where one is taking care of to become a place by which one is taken care of.
