Critical Overview of Screening Tools for Detecting Bipolar Disorders
Bibliographic record
Abstract
This overview aims to explore the key screening tools for detecting bipolar disorders (BDs): the Mood Disorder Questionnaire (MDQ), Bipolar Spectrum Diagnostic Scale (BSDS), Hypomania Checklist (HCL-32), and Rapid Mood Screener (RMS), while offering guidance to healthcare professionals in selecting the most appropriate tool for each clinical scenario. The MDQ is widely utilized due to its high specificity (0.90) for identifying Bipolar Disorder (BD) in psychiatric consultations, although it is more sensitive to bipolar I than bipolar II. The BSDS, designed to encompass a wider range of bipolar spectrum symptoms, exhibits a sensitivity of 0.70 and specificity of 0.89, which makes it a complementary tool to the MDQ. The HCL-32 concentrates on detecting hypomanic traits in Major Depressive Disorder (MDD) patients, showing good sensitivity (80%) but lower specificity (51%). It is particularly effective for distinguishing BD from unipolar depression, although it cannot differentiate between Bipolar Disorder type I (BDI) and Bipolar Disorder type II (BDII). The RMS is a newer tool that quickly screens for manic symptoms and risk factors, boasting a sensitivity of 0.88 and a specificity of 0.80. Together, these screening instruments facilitate the early identification of BDs, though positive results should always be followed by a thorough clinical evaluation. Employing multiple tools simultaneously can improve diagnostic accuracy and more effectively capture the diverse presentations of BDs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
