OCD Flares Now Predictable Hours Ahead: Low Confidence Is Warning Signal

A UCL study published in Nature Communications reports that drops in self-confidence can serve as a warning signal for obsessive-compulsive disorder episodes up to four hours before they occur. The researchers at University College London’s Max Planck Centre for Computational Psychiatry and Ageing Research say symptoms themselves don’t reliably predict escalation at the same lead time; instead, confidence declines precede flares. Using ecological momentary cognitive testing (EMCT), the team combined smartphone-based experience sampling with a brief gamified cognitive task over 14 days in real-world settings. The study involved 137 participants in the U.K. with self-declared OCD, recruited via Prolific, scoring at or above 21 on the Obsessive-Compulsive Inventory-Revised. Participants received four daily notifications and logged episodes through the app.
