The difference between the UP and ENP groups: The UP-group receives a fixed amount of intervention = five sessions (three for the student and two for the parents) each month in which relevant treatment is picked from the intervention approaches mentioned above. The ENP-group receives the same treatment options from the intervention list but in an enhanced form. This group receives not less than seven sessions (four for the student and three for the parents). Furthermore, in the ENP-Group, there is no limit regarding the number of interventions. The psychologist will evaluate how many sessions he considers are needed to progress in each case.
