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.
