The Beck Depression Inventory assesses how closely an individual���s behavioral symptoms match the criteria for depression as described in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, informs the Medical University of South Carolina. Question items address changes in sleep, appetite, energy and mental concentration. The test asks the individual to rate how well each question or statement applies to the way he has felt over the past two weeks using a four-point rating scale for symptom severity.
Higher overall scores on the BDI assessment are associated with more depressive symptoms, adds the Medical University of South Carolina. The overall assessment score is based on the sum of the scores from each of the 21-question items. A total BDI score of 0 to 13 indicates minimal depression, a score of 14 to 19 indicates mild depression, 20 to 28 indicates moderate depression and scores of 29 to 63 indicate severe symptoms of depression.

Because the assessment is self-reported, the results are susceptible to exaggeration or understatement by the individual undergoing the assessment.Learn more about Mental Health
