The phenomenon of school avoidance is multifaceted and requires effective measures for the reintegration of mentally ill children and adolescents from psychiatry back into regular schools. This responsible task necessitates proven reintegration concepts. A selection of current school reintegration concepts is compared in this book. Self-developed materials, conceived during a three-year research project, are provided and illustrated with the help of case vignettes. The work includes a contribution from Volker Reissner, Alexander Wertgen, Johannes Helmig, and Johannes Hebebrand.
