Psychological stress and disorders are often triggers or results of school avoidance in students who frequently or continuously miss school, which can lead to a lack of school qualifications and very limited job opportunities. This manual serves as a foundation for a multiprofessional consultation and treatment of school avoiders and their parents. It consists of four coordinated modules: 1. Cognitive Behavioral Therapy with a primary focus on reintegration into school, 2. Family counseling, 3. Educational counseling, 4. Sports and psychoeducation. The aim is to improve the mental well-being of these troubled students and enable them to return to school quickly. The manual has been scientifically evaluated: it proved to be as effective as treatment concerning reintegration into school.
