Abstract

Aim - Recent findings suggest that OCS are prevalent in individuals with early psychosis. However, their clinical relevance still needs to be clarified. This research specifically explored OCS in subjects at Clinical High Risk for Psychosis (CHR P), with the aims of determining their baseline prevalence, examining their 2-year stability, and analyzing their association with sociodemographic data, clinical characteristics and outcomes. Methods - Clinical assessments at baseline and during the 2-year follow-up period included: the Comprehensive Assessment of At-Risk Mental states (CAARMS), the Positive And Negative Syndrome Scale (PANSS), and the Global Assessment of Functioning (GAF). OCS were identified using the CAARMS item 7.6 subscore. Results - Among 180 CHR-P participants, 66 (36.7 %) had OCS at baseline. CHR-P with OCS had higher PANSS scores and greater antidepressant prescription rates. OCS severity levels improved in the first year, but plateaued over two years, correlating with longitudinal changes in GAF and PANSS total scores. OCS improvement was specifically associated with antidepressant use and intensity of individual psychotherapy sessions. CHR-P subjects with OCS had higher service engagement rates. Conclusions - The presence of OCS could characterize a distinct CHR-P subtype with specific clinical and prognostic characteristics, requiring tailored diagnostic and therapeutic approaches. Recognizing the heterogeneity in CHR-P population is crucial for optimizing care. [ABSTRACT FROM AUTHOR]
