What does the BDI measure?
The Beck Depression Inventory – Second Edition (BDI-II) is a 21-item self-report instrument for measuring the severity of depression. During the last 35 years, the BDI has become one of the most widely accepted instruments for assessing the severity of depression in diagnosed patients and for detecting possible depression in normal population.
What does the BDI questionnaire consist of?
Each item of the BDI is rated on a 4-point scale of distress (0-3), in terms of severity. Maximum score is 63.
How does the BDI scoring work?
The instrument can classify four different levels of depression:
- Minimal depression
- Mild depression
- Moderate depression
- Severe depression
Subscales that have been identified are:
- Affective
- Cognition
- Somatization
The BDI-II has been rated to be a sufficient reliable, sensitive, and valid questionnaire. The questionnaire is sensitive to treatment effects.
