AbstractIntroduction: Achieving functional recovery in patients with psychosis is a challenge in clinical practice. Investigating the complex interplay between cognition, symptoms, insight and functional outcome in first episode psychosis will be crucial to understanding the factors leading to better functioning. Methods: In this 12-month prospective follow-up study, we investigated how cognition, clinical symptoms, and insight into illness affected overall functioning in 160 patients with first episode psychosis recruited from the Early Assessment Service for Young People with Psychosis (EASY) in Hong Kong from July 1, 2014 to June 30, 2016. Cognition was assessed at baseline while symptoms, insight, and functioning were assessed at 12-month follow-up. Structural equation modelling was used to examine the direct and indirect relationships between functioning and other latent constructs. Results: Symptoms (negative symptoms and general psychopathology) and insight were shown to be significant mediators between cognition and functioning. The significant direct relationship between cognition and functioning (β = 0.387; p < 0.001) became insignificant (β = 0.079; p = 0.578) after including symptoms and insight in the model. Symptoms and insight were significantly associated with cognition (symptoms, β = −0.469; p < 0.001; insight, β = −0.372; p < 0.001) and predicted functioning (symptoms, β = −0.558; p < 0.001; insight, β = −0.264; p < 0.01). Conclusion: Symptoms and insight mediated the effects of cognition on functioning. Interventions for improving functioning in patients with first episode psychosis should target not only cognition but also symptoms and insight.
