Abstract
Automated syntactic markers distinguished patients with first-episode psychosis from healthy controls in a Brazilian Portuguese-speaking sample, achieving 81% cross-validated accuracy (AUC = 0.86). These findings largely replicate prior results in Dutch, underscoring the potential of automated syntactic measures to identify early psychosis across languages, illness stages, and speech elicitation tasks.
