Run by University Hospital, Brest · NCT03525054 · Data updated 2026-11-12
This study is trying to see if analyzing the way people at high risk for schizophrenia speak can help predict if they will develop psychosis.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study aims to identify linguistic markers that may predict the transition to schizophrenia in patients at ultra-high risk. By utilizing computerized speech analysis techniques, including Latent Semantic Analysis, the study will analyze speech patterns from audio recordings of initial medical interviews. The goal is to validate a predictive model in the French language that can accurately forecast psychotic transitions based on subtle speech disorganization. The study will involve a longitudinal multicenter cohort approach to gather comprehensive data over time.
Why it matters
Potential benefit: If successful, this study could lead to early identification and intervention for individuals at risk of developing schizophrenia.
How similar studies have gone: Previous studies using computerized speech analysis have shown promise in identifying markers for schizophrenia, suggesting this approach may be effective.
