The Bipolar Spectrum Diagnostic Scale (BSDS) is a test for subtle versions of bipolar disorder. Before you start this test, you should know that it will not give you a “yes or no” answer.  Mood problems fall on a spectrum from plain depression to “bipolar”. This test may help you understand where on that spectrum your depression falls.

There is another test, called the MDQ, that you may run into which gives a “yes or no” answer, but is thus capable of giving a “wrong” answer. In fact, both of these tests have a problem with potential “false positives” — saying you have bipolar disorder when you don’t. So you must interpret your results carefully, by learning a lot about subtle bipolarity.

At some point you may see a mental health professional, either a skilled therapist like an MSW, or Ph.D. psychologist; or a psychiatrist. If they give you a diagnostic opinion that differs from your self-educated impression, you can discuss the differences in your points of view. If the difference is not resolved, you could try to get a second opinion. This diagnosis is very tricky territory.

If you would like a paper-and-pencil version of this test that you can easily take to your doctor, here is  the BSDS combined with other useful information for professionals. Use it instead of the one below.
