In order to solve the most complex problems surrounding services to young people with multiple needs, the Quebec intersectoral coordination mechanism Équipe Intervention Jeunesse implements partnership mediation practices with the families and organizations involved. To better understand the reasons justifying the use of such a mechanism, a study explored the lived experience of 15 parents. The results show how the reality of the child, but also the relationships experienced with organizations that try to help them, influence the experience of families. The study highlights the words of parents and reveals that their experience is more complex both by their daily family reality and by the collaborative relationship with the school community and the service network.
