The BDI is one of the most widely used screening instruments for measuring the severity of depression in adults and adolescents.

Interpretability: Higher scores reflect more symptoms of depression. For clinical populations, a cut score of 13 has been recommended for screening purposes.
Time to administer: At least 10 minutes, although completion time may vary due to the patients’ severity of symptoms.
Time to score:Unknown, but the burden is likely minimal.
Training required: None.
Equipment required: None.
