A cluster RCT to improve workplace mental health in a policing context: Findings of a mixed-methods implementation evaluation.

Background: We conducted a cluster randomized trial of a workplace mental health intervention in an Australian police department. The intervention was co-designed and co-implemented with the police department. Intervention elements included tailored mental health literacy training for all members of participating police stations, and a leadership development and coaching program for station leaders.

The Vitamins in Psychosis Study: A Randomized, Double-Blind, Placebo-Controlled Trial of the Effects of Vitamins B, B, and Folic Acid on Symptoms and Neurocognition in First-Episode Psychosis.

Background: Elevated homocysteine is observed in schizophrenia and associated with illness severity. The aim of this study was to determine whether vitamins B, B, and folic acid lower homocysteine and improve symptomatology and neurocognition in first-episode psychosis. Whether baseline homocysteine, genetic variation, sex, and diagnosis interact with B-vitamin treatment on outcomes was also examined.

Depression literacy and help-seeking in Australian police.

Objective: To assess depression literacy, help-seeking and help-offering to others in members of the police force in the state of Victoria, Australia.

Methods: All staff in police stations involved in a cluster randomised controlled trial of an integrated workplace mental health intervention were invited to participate. Survey questions covered sociodemographic and employment information, recognition of depression in a vignette, stigma, treatment beliefs, willingness to assist co-workers with mental health problems, help-giving and help-seeking behaviours, and intentions to seek help.

Adjunctive Taurine in First-Episode Psychosis: A Phase 2, Double-Blind, Randomized, Placebo-Controlled Study.

Objective: Taurine is an inhibitory neuromodulatory amino acid in the central nervous system that activates the GABA- and glycine-insensitive chloride channel and inhibits the N-methyl-D-aspartate receptor. It also functions as a neuroprotective agent and has a role in neural development and neurogenesis. The aim of this study was to determine the efficacy of adjunctive taurine in improving symptomatology and cognition among patients with a DSM-IV first-episode psychotic disorder.

Examining the association between social cognition and functioning in individuals at ultra-high risk for psychosis.

Objective: Social and role functioning are compromised for the majority of individuals at ultra-high risk of psychosis, and it is important to identify factors that contribute to this functional decline. This study aimed to investigate social cognitive abilities, which have previously been linked to functioning in schizophrenia, as potential factors that impact social, role and global functioning in ultra-high risk patients.

Method: A total of 30 ultra-high risk patients were recruited from an established at-risk clinical service in Melbourne, Australia, and completed a battery of social cognitive, neurocognitive, clinical and functioning measures.

Externalized attributional bias in the Ultra High Risk (UHR) for psychosis population.

Specific externalizing attributional biases appear to be common in early psychosis. They may represent trait risk factors for the later development of a psychotic disorder, yet few studies have investigated this in clinical "at risk" populations. We aimed to investigate one particular bias, the Locus of Control of reinforcement (LOC) in a "Ultra High Risk" (UHR) for psychosis group.

Social cognition in clinical "at risk" for psychosis and first episode psychosis populations.

Background: Social cognitive deficits have been demonstrated in first episode psychosis (FEP) and groups at high risk for developing psychosis but the relative degree of deficit between these groups is unclear. Such knowledge may further our understanding of the importance of these deficits in the development of psychosis. The study aimed to compare the degree of impairment in social cognition in three groups: FEP, those at "ultra high risk" (UHR) for psychosis and healthy controls.
