The Inventory of Depressive Symptomatology (IDS): Clinician (IDS‐C) and Self‐Report (IDS‐SR) ratings of depressive symptoms

This paper describes the rationale and methods entailed in developing the Inventory of Depressive Symptomatology (IDS) in both clinician‐rated (IDS‐C) and self‐reported (IDS‐SR) formats. Psychometric features of the both the IDS‐C and IDS‐SR are presented. These scales are compared to the Hamilton Rating Scale for Depression (HRS‐D) in the detection of symptom change in patients with major depressive (n = 184) or bipolar disorder (n = 141). The face validity and established psychometric features of the IDS‐C and IDS‐SR indicate that either may be useful in detecting symptom change, as well as in detecting residual symptoms in depressed patients. Further efforts to shorten each measure are indicated. Copyright © 2000 Whurr Publishers Ltd.
