Beck Depression Inventory

  • BDI developed by Aaron T. Beck is a 21-question self-reporting inventory for evaluating the severity of depression

  • Created in 1961, it relied on the theory of negative cognitive distortions as the main point of depression. Throughout the years, it has undergone revisions in 1978 (BDI-1A) and in 1996 (BDI-II).

  • BDI-II, a revision of the BDI in 1996, serves as a response to the publication of the DSM-IV, which updated and changed diagnostic criteria for Major Depressive Disorder

  • It does not heavily rely on any theory of depression

  • The inventory has also been translated in several languages to cater to other people who do not understand English

Aaron T. Beck

  • An American psychiatrist known for developing self-report measures of depression and anxiety

  • father of Cognitive Behavioral Therapy

  • Created multiple assessment scales

  • published more than 600 papers and 24 books

History

  • Publication and Revisions

    • 1961: 1st publication (BDI/BDI-I)

    • 1979: extended timeframe and reworded items (BDI-1A)

    • 1987: technical manual was included (BDI-1A)

    • 1993: revision of the technical manual (BDI-1A)

    • 1996: committed items related to weight loss, body image, hypochondria, and working difficulty and replaced them with agitation, worthlessness, difficulty concentrating and energy loss; amended items on appetite and sleep change (BDI-II)

    • 2000: contained 7 items from BDI-II to assess depression in individuals with biomedical or substance abuse problems (BDI-FS/BDI-PC)

Purpose

  • The test is a cost-effective questionnaire used in measuring the severity of one’s depression

  • it is used to gauge the intensity of depression among patients who meet the criteria in diagnosing depressive syndromes

  • It evaluates key symptoms of depression such as mood, pessimism, sense of failure, guilt, self-dislike, suicidal ideas, working difficulty, and more

  • Individuals with are 13 years old and above can take this test

  • It is also recommended that the client taking the test should have a fifth to sixth reading comprehension to fully understand the questionnaire

Administration

  • The test was originally designed to be administered by a licensed psychometrician. However, it can now be self-administered, after which the results are reported orally in individual or group settings

  • Respondents must describe their feelings over the past 2 weeks

  • Answering the test itself takes about 5-10 minutes

  • the self-report can be done in 15 minutes

Scoring

  • How to score

    • scored by summing the ratings for the 21-items

    • each item is rated in a 4-point scale ranging from 0 to 3

  • How to compute

    • computed by summing all 21 items to give a single score

    • special attention must be paid to the correct scoring of the item #16 (changes in sleeping pattern) and item #18 (changes in appetite)

    • each of these items contains seven options rated in order, 0, 1a, 1b, 2a, 2b, 3a, 3b, to differentiate between increases and decreases in behavior or motivation

    • these items indicate whether there is an increase or decrease in sleep and appetite

    • if a higher rated option is chosen by the respondent, the presence of increase or decrease in either symptom should be clinically noted for diagnostic purposes

  • Interpretation of scores

    • total score

      • 0-13 indicates minimal depression

        • no treatment required

      • 14-19 indicates mild depression

        • possible medications (low dose) can be given

        • therapy can also be given to patients

      • 20-28 indicates moderate depression

        • treatment is similar with mild depression (i.e., low dose of medications and/or therapy)

      • 29-63 indicates severe depression

        • professional help must be given to provide proper treatment to patients
