Introduction and description The Beck Depression Inventory is a self-report inventory that attempts to understand the severity of depression in adults and/or adolescents. The original Beck Depression Inventory was created in 1961 by Aaron Beck and his associates and was revised in 1971. In 1971, the Beck Depression Inventory was introduced at the Center for Cognitive Therapy, CCT, at the University of Pennsylvania Medical School. Much of the research on the Beck Depression Inventory was conducted at the University of Pennsylvania Medical School. In the current version of the Beck Depression Inventory, the subject rates 21 symptoms and attitudes on a 4-point scale depending on severity. Test takers rate the items listed in the inventory over a one-week period, which includes the day the test takers took the test. The items measured by the inventory cover the cognitive, somatic, affective, and vegetative dimensions of depression, and although they were developed atheoretically, the items correspond to the symptoms of depression as outlined in the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV, American Psychiatric Association, 1994). The Beck Depression Inventory is widely known and is well understood by psychiatric populations and clinicians. The BDI can be administered in a group or individual format in oral or written form. The 1993 version targets more characteristic aspects of depression than previous versions that measured state aspects of depression. The test must be administered with no more than 15 minutes to take the test, regardless of the mode administered. The 21 symptoms rated on the 4-point scale are then added and the range can vary from 0 to 63.
