Modified on: Mon, 25 Apr, 2022 at 11:02 AM



Some key differences between the BDI-2 and BDI-3 include: 

  • Demographic differences

  • Repositioning of test items

  • Updated test content

  • Revised item scoring criteria

  • Differences in derived scores


Because of these differences, trying to compare the BDI-2 to the BDI-3 is like trying to compare apples to oranges.
