Covariates include gender, age, migration background, 2-digit address postcode and the year and month of record opening. The DSM-IV diagnosis include 97 dummies for diagnosis categories at the DSM-IV 3rd level and binary indicators for having either 2 or 3 or more concurrent diagnoses. Initial GAF (dummies for each category) and treatment minutes in the first column concerned the inclusion of these measures as controls for the subsequent outcomes models. Each GAF category corresponds to a 10-point interval in GAF =score (e.g. GAF category 1 corresponds to 1-10 points, 2 to 11-20, …, 10 to 91-100). GAF=Global Assessment of Functioning.
