BSDS

Clinical Scales

The BSDS was developed by Ronald Pies, MD, and was later refined and tested by S. Nassir Ghaemi, MD, MPH, and colleagues. The 19 items on the English version of the BSDS were based on questions that Dr Pies found most helpful in detecting not only severe cases of bipolar disorder but also patients who fall into the softer end of the bipolar spectrum (eg, patients with a history of major depressive episodes and 1 or 2 episodes of elevated mood and energy that last only 1 to 3 days, thus not meeting DSM-IV criteria for hypomania).

You can also download a printable version, scoring instructions , or continue with the Bipolar Spectrum Diagnostic Scale.
