Baseline Exposure to Antipsychotic Medication in Young People at Clinical High Risk for Psychosis: A 2-Year Italian Follow-Up Study.

ABSTRACT:

Objective

Despite various models examining baseline factors, predicting outcomes in individuals at clinical high risk for psychosis (CHR-P) remains challenging. Specifically, neglecting factors like ongoing antipsychotic (AP) medications introduce bias and reduce method precision. The main aim of this research was to determine if the presence of AP prescription at baseline identifies a CHR-P subgroup with worse prognostic outcomes over a 2-year period.

Methods

A group of 180 FEP individuals (92 CHR-P/AP+, 88 CHR-P/AP-) were evaluated at baseline and after 24 months using the PANSS and GAF scales. Individuals with baseline AP prescription were included in the CHR-P/AP+ subgroup; those not taking APs were grouped as CHR-P/AP-. Univariate Cox regression analysis and mixed-desig
