Sex comparisons on the beneficial effects of an early intervention program in a patients' cohort with first episode psychosis: what effectiveness in women?

Abstract

Purpose: Males and females with First Episode Psychosis (FEP) usually tend to differ in psychopathology, clinical presentation and their longitudinal trajectory. This study aimed to examine the difference of effectiveness of specialized psychosocial and pharmacological treatments for FEP, focusing on various clinical and functioning outcomes across a 2-years follow-up period.

Methods: The assessment included the CAARMS, the HoNOS, the PANSS and the GAF scale and was conducted at baseline and every 12 months.

Results: 490 FEP patients (age: 12-35 years) were recruited. Of them, 363 completed the follow-up (132 females and 231 males). At baseline, males showed a higher prevalence rate of schizophrenia diagnosis (56.1% VS 43.8%; p = .008), whereas females a higher prevalence rate of affective psychosis (36.2% VS 23.3%; p = .005). Male participants also showed a more consistent substance abuse (46.9% VS 24.3%; p = .0001), lower years of education (11.26 ± 2.94 VS 11.88 ± 2.68; p = .013), and more striking behavioral manifestations (4.06 ± 2.36 VS 3.39 ± 2.58; p = .003) compared to women. Our 2-year outcome parameter results showed a higher incidence of functional remission over time in females compared to males (49.2% VS 39.0%; p = .028), together with a decreasing trend in new hospitalization rates (17.8% VS 26.9%; p = .089). Independently from sex, our results also showed a statistically significant reduction in the prescription of psychotropic medications and through the increase of all psychosocial interventions, although more evident in males.

Conclusion: These results suggested that specialized interventions for FEP are overall effective in both treated subgroups. Additionally, FEP women specifically showed higher rates of improvement in functional outcome variables over time when compared to males.
