Bipolar Spectrum Diagnostic Scale, BSDS

Online Test


Bipolar Spectrum Diagnostic Scale (BSDS) was developed by Ronald Pies (Ronald Pies) and further refined by Nassir Ghaemi (S. Nassir Ghaemi) together with colleagues. The method is intended to identify signs of conditions related to the bipolar spectrum — both pronounced and moderate forms.

The scale describes characteristic changes in mood and energy level — ranging from increased activity and elevated mood to periods of fatigue and reduced emotional state. Based on the overall responses, the degree of these fluctuations and their impact on the general condition is determined.

BSDS helps to form a comprehensive understanding of possible manifestations of the bipolar spectrum and serves as a supplementary tool for the preliminary assessment of emotional stability.
