The DSM-IV diagnosis includes dummies for each diagnosis category 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 concern 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 score; SD – standard deviation; CI – confidence interval. 2
