Beck Depression Inventory-Second Edition (BDI-II)

Beck Depression Inventory-Second Edition (BDI-II)

Type: 11-item self-report inventory


Overview: . The BDI-II was revised in 1996 to be more consistent with DSM-IV criteria for depression. Individuals are asked to respond to each question based on a two-week time period rather than the one-week timeframe on the BDI. The BDI-II is widely used as an indicator of the severity of depression, but not as a diagnostic tool, and numerous studies provide evidence for its reliability and validity across different populations and cultural groups. It has also been used in numerous treatment outcome studies and in numerous studies with trauma-exposed individuals.

Additional information: The BDI takes approximately 10 minutes to complete, although clients require a fifth – sixth grade reading level to adequately understand the questions.
