Aim: This study aimed to determine which of demographic/premorbid, psychiatric or neuropsychological variables are most closely associated with functional status around the time of diagnosis of first-episode psychosis. This was with a view to determining factors that should be the focus of intervention in these early stages of illness.
Methods: The Western Sydney First Episode Psychosis Project collected data on young persons (aged 13-25) with newly diagnosed psychosis (n=92). Psychosocial functional status was measured using the Role Functioning Scale (RFS). Multiple regression analyses were carried out to identify predictors of RFS score from a wide range of predictor variables.
Results: Psychiatric variables accounted for the most variance in RFS score. Positive and Negative Syndrome Scale (PANSS) Negative subscale and Young Mania Rating Scale score were found to be significant individual predictors, with variables from the other domains failing to contribute to the overall model. In separate models, demographic/premorbid and neuropsychological factors weakly related to functional status.
Conclusions: Psychiatric factors were the main influence on psychosocial functioning in first-episode psychosis at baseline. Evidence suggests the relationships between symptoms, cognition and demographics with function might change over time, depending on the stage of illness being examined.

Reimagining psychosis prevention: responding to the accessibility issues of At-Risk Mental State (ARMS) services through a selective public health approach.

At-Risk Mental State (ARMS) services aim to prevent the onset of first-episode psychosis (FEP) in those with specific clinical or genetic risk markers. In England, ARMS services are currently expanding, but the accessibility of this preventative approach remains questionable, especially for a subgroup of FEP patients and those from specific ethnic minority communities. This commentary outlines the key debates about why a complimentary approach to psychosis prevention is necessary, and gives details for an innovative public health strategy, drawing on existing research and health prevention theory.

Objectives: To establish whether the risk of psychotic disorders in cannabis users changes with time following cannabis cessation using data from the European Network of National Networks studying Gene-Environment Interactions in Schizophrenia (EU-GEI) case-control study.
Methods: The EU-GEI case-control study collected data from first episode psychosis patients and population controls across sites in Europe and Brazil between May 2010 and April 2015. Adjusted logistic regressions were applied to examine whether the odd of psychosis case status changed: (1) with time following cannabis cessation and (2) across different cannabis use groups.

Objective: The first-episode psychosis (FEP) and clinical high-risk (CHR) team within the child and adolescent mental health (CAMH) service receives referrals by psychiatric units, CAMH service, schools, and general practitioners. This audit evaluated the implementation of the FEP-CHR team in Ferrara, Italy.
Methods: The FEP-CHR team provides standardised assessment and up to 2-year individualised treatment including pharmacological prescription, cognitive-behavioral psychotherapy, and vocational activities.
Efficacy of solution-focused brief therapy versus case management for psychological distress in adolescents and young adults in a community-based youth mental health service in Singapore: protocol for a randomised controlled trial.

Introduction: There are insufficient scalable, evidence-based treatments to meet increasing mental health needs of young people. Offering interim, brief interventions for young persons with psychological distress can improve access to care and mitigate adverse effects of long waiting times. This study tests the efficacy of solution-focused brief therapy (SFBT), a strength-based, goal-directed intervention, in adolescents and young adults at a community-based youth mental health service in Singapore.

Article Synopsis
- The study investigates how childhood trauma affects brain connectivity in patients experiencing their first episode of psychosis compared to healthy controls.
- Higher scores of sexual abuse and emotional neglect from childhood trauma were linked to increased functional connectivity between specific brain regions (like the amygdala and prefrontal cortex) in these patients.
- The findings suggest that different types of childhood trauma have distinct long-term effects on brain function, highlighting the complex relationship between trauma and psychosis.
