BSDS
Bipolar Spectrum Diagnostic Scale (BSDS)
The BSDS is a self-administered screening tool designed to identify bipolar spectrum disorders. It focuses on recognizing attenuated or atypical forms of bipolar disorders, which are often difficult to diagnose with other questionnaires. This test is useful in clinical practice as an initial screening tool.

Scoring & interpretation
The scale consists of a short narrative with which the patient must identify, followed by several dichotomous questions. The total score is calculated by summing the positive answers. A high score indicates an increased likelihood of a bipolar spectrum disorder. Scores are interpreted according to specific cutoffs recommended in the manual.
