The 4\u2010item Catatonia Quick Screen (CQS) allows rapid screening, but its specificity requires evaluation. We assessed CQS sensitivity and specificity using the original Bush Francis Catatonia Rating Scale (BFCRS) cohort.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Retrospective reanalysis of data from 215 consecutive inpatient psychiatric admissions. CQS classifications were compared against BFCRS, DSM\u20105\u2010TR, and ICD\u201011 criteria. 95% confidence intervals (CIs) were calculated via Clopper\u2010Pearson exact methods, treating the eight single\u2010sign patients conservatively as false positives.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n All 15 catatonia cases screened positive (true positives). The CQS demonstrated 100% sensitivity (95% CI: 78.2% to 100%), 96.0% specificity (95% CI: 92.3% to 98.3%), 65.2% positive predictive value (95% CI: 42.7% to 83.6%), and 100% negative predictive value (95% CI: 98.1% to 100%).<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n The CQS showed excellent sensitivity and high specificity in this psychiatric cohort. It serves as a rapid, low\u2010burden screening tool to accelerate clinical recognition, though positive results require formal diagnostic confirmation.<\/jats:p>\n
