Subjects also completed the Beck Depression Inventory (BDI) to assess depressive symptomatology.
The Beck Depression Inventory or BDI has been updated; it has been changed in order to better address the needs of people suffering from depression.

You can view much more information about BDI II assessment scoring and reliability at the Association for Assessment in Counseling and Education.
While some think that the BDI II alone can effectively diagnose depression, that's not actually what the inventory does.
