Sex differences have been observed in individuals with schizophrenia and for those at clinical high risk (CHR) for psychosis. However, specific differences in CHR individuals who transition to psychosis remain inconsistent and understudied. This study aimed to investigate sex differences in 156 CHR individuals who made the transition to psychosis. A wide range of demographics, positive and negative symptoms, depression, anxiety, social and role functioning, trauma, and substance use were assessed at baseline and symptoms and diagnoses at the time of transition. Fluctuations in positive and negative symptoms and different medications were also assessed. No sex differences were observed at baseline for those who later transitioned to psychosis. At transition, males were significantly more likely to be diagnosed as having schizophrenia or schizophreniform disorder and through the course of the study, males were more likely to be taking stimulants. Limitations in this study was the lack of longitudinal follow-up post transition. The study highlights the need for further research on sex differences in individuals who transition to psychosis. Understanding these differences can have implications for treatment and monitoring of CHR individuals.
