 The clients of this trial are adolescents who either self-refer themselves, are referred by other school personnel, or by their parents to the services offered in the school by school nurses, school social workers or school psychologists because of emotional symptoms in the school year 2016 -2017 in each of the participating schools. They are first screened on their first visit with a self-report instrument, the Beck Depression Inventory BDI-21; Beck et al., 1961 to identify symptoms of depression. If they are present above the clinical cutoff for mild depressive symptoms, a clinical interview K-SADS-PL adapted to DSM-5; see Kaufman et al., 1997 by a trained research coordinator follows. In this stage, the main inclusion criterion for the study, a diagnosis of a DSM-5 depressive disorder, severity either mild or moderate, is ascertained. As an exclusion criterion, current harmful alcohol use as assessed by AUDIT Babor et al, 2001 is ruled out. Also the presence of acute suicidal ideation or behavior, severe depression or anxiety disorder, psychotic symptoms or very low global level of functioning are exclusion criteria, and if present these adolescents are offered other treatment. Those fulfilling the inclusion criteria are referred to either a project IPC counselor, or a project worker delivering ST, depending on the status of the school in the cluster randomization.
