    When to Use
    Why Use
    • Patients who identify as depressed or who may be suffering from depression.
    • The QIDS can also be trended over time to help providers and patients alike see trends like improvements in depressive symptoms over time.

    The MDI can help objectify and rate the severity of a patient's depression.
