Answer

The use of depression rating scales is recommended. Many rating scales, both self-administered and clinician rated, are available. The clinician-administered, 17-item Hamilton Rating Scale of Depression (HAM-D) and the self-report scales known as the Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16), the Patient Health Questionnaire-9 (PHQ-9), and the Beck Depression Inventory (BDI) are all commonly used.

Simple enough to use on a routine basis, these scales offer diagnostic confirmation and provide a baseline against which change can be evaluated. Studies have emphasized the importance of these rating scales in detecting small changes that may indicate the initial phases of a treatment response. [24] However, use in dysthymia may be different from use in major depressive disorder.
