Beck Depression Inventory Analysis
The Beck Depression Inventory was developed by Aaron Beck was first used in 1961, and was later revised as Beck Depression Inventory-II in 1979. It was published by the Center for cognitive therapy. BDI was developed as a personality assessment to help measure depressive episodes in an individual. BDI-II began as paper-and-pencil evaluation and has now been integrated as a computer based assessment with 21 items in multiple-choice form and is administered to a group or individual that is purchased by a clinician. The norm sample for the BDI-II consisted of two samples; one was a clinical sample of 500 participants with 63% of those being female and 91% of the sample being white on the eastern coast of the US from four different outpatient clinics.
