Protocol Name from Source:
The Quick Inventory of Depressive Symptoms (QIDS)
Personnel and Training Required
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
Adults, ages 18 and older.
When using this protocol, please inform your Institutional Review Boards of these questions and institute a plan of action for dealing with suicidal thoughts in your respondent. It may be necessary to create a separate protocol for immediate action and/or referral.
The Quick Inventory of Depressive Symptoms (QIDS) was vetted against several other dimensional measures for depression and ultimately selected because it is free, easily administered as a self-reported instrument for ages 12 and above, and captures the general symptoms of depression.
Process and Review
Expert Review Panel 4 (ERP 4) reviewed the measures in the Neurology, Psychiatric, and Psychosocial domains.
Guidance from ERP 4 included the following:
- Added new measure
- No changes to existing protocol

A self-report questionnaire to assess symptoms of major depressive disorder (MDD).
This measure can be used to rapidly assess depressive symptoms and select cases and non-cases. Depression is a common disorder that demonstrates a familial pattern and is comorbid with other psychiatric disorders, including anxiety disorder, substance use disorders, and eating disorders. Additionally, certain medical conditions-such as diabetes, stroke, and heart disease-can increase the risk of depression. Some individuals who present with major depressive episodes may have a bipolar spectrum disorder.
