First episode psychosis and beyond: much progress made but much more needed.

First episode psychosis remains one of the most critical research areas in psychiatry. Much progress has been made, but more progress is required to translate the ideas and promises into reality. In this Editorial, we provide the context and invite contributions for our BMC Psychiatry Collection on First Episode Psychosis.

Renewal of academic psychiatry without addressing gender equity will render it Jurassic rather than endangered.

While two editorials have raised concerns about the decline in Australian academic psychiatry, for a genuine rejuvenation to ever occur, we will need to re-examine how women can be better included in this important endeavour. While attainment of fellowship has reached gender parity, academic psychiatry has disappointingly lagged, with 80% of its senior leadership roles across Australia and New Zealand still held by men, with a similar situation in the United Kingdom and the United States as well as many other countries. Encouraging women into academic psychiatry is not only critical to progress as a profession but also will help address the current blindness to sex differences in biological psychiatry, as well the social impact of restrictive gender norms and the effects of gender-based violence on mental health. This potentially creates opportunities for significant gains and insights into mental disorders. However, addressing the barriers for women in academia requires tackling the entrenched disparities across salaries, grant funding, publications, teaching responsibilities, keynote invitations and academic promotions alongside the gender-based microaggressions, harassment and tokenism reported by many of our female academics. Many women must grapple with not just a 'second shift' but a 'third shift', making the burden of an academic career unreasonable and burnout more likely. Addressing this is no easy task. The varied research in academic medicine reveals no quick fixes, although promoting gender equity brings significant potential benefits. Areas such as academic psychiatry need to recognise our community's growing discomfort with workplaces that choose to maintain status quo. Gender equity must be a critical part of any quest to revive this important area of practice for our profession.

Reversal learning in those with early psychosis features contingency-dependent changes in loss response and learning.

INTRODUCTION: People with psychotic disorders commonly feature broad decision-making impairments that impact their functional outcomes. Specific associative/reinforcement learning problems have been demonstrated in persistent psychosis. But these phenotypes may differ in early psychosis, suggesting that aspects of cognition decline over time. METHODS: The present proof-of-concept study examined goal-directed action and reversal learning in controls and those with early psychosis. RESULTS: Equivalent performance was observed between groups during outcome-specific devaluation, and reversal learning at an 80:20 contingency (reward probability for high:low targets). But when the low target reward probability was increased (80:40) those with early psychosis altered their response to loss, whereas controls did not. Computational modelling confirmed that in early psychosis there was a change in punishment learning that increased the chance of staying with the same stimulus after a loss, multiple trials into the future. In early psychosis, the magnitude of this response was greatest in those with higher IQ and lower clinical severity scores. CONCLUSIONS: We show preliminary evidence that those with early psychosis present with a phenotype that includes altered responding to loss and hyper-adaptability in response to outcome changes. This may reflect a compensatory response to overcome the milieu of corticostriatal changes associated with psychotic disorders.

Formulation in psychiatry - a guide to developing competence.

OBJECTIVE: This paper highlights the importance of psychiatric formulation and provides guidance to those learning the art of formulation. To achieve this, we explore the guidance on formulation that has been previously published in Australasian Psychiatry, identify the key components of psychiatric formulation, and outline an approach to comprehensive formulation in routine clinical practice. CONCLUSION: Formulation is the foundation of good psychiatric practice but presents a considerable challenge to the novice practitioner. Understanding the ingredients of formulation and a method for meaningfully putting these together will guide deliberate practice to learn the art of psychiatric formulation.

A model of care for attention deficit and hyperactivity disorder among adults in the community.

OBJECTIVE: To describe the process of collaborative, contextualised development and implementation of a model of care for adults with symptoms suggestive of attention deficit and hyperactivity disorder in an Aboriginal community-controlled health service. CONCLUSION: The current article describes an attempt to reduce unmet mental health needs through a systemic approach within a well-established Indigenous community-controlled organisation.

Impairments in goal-directed action and reversal learning in a proportion of individuals with psychosis.

Cognitive impairment in psychosis is one of the strongest predictors of functional decline. Problems with decision-making processes, such as goal-directed action and reversal learning, can reflect cortico-striatal dysfunction. The heterogenous symptoms and neurobiology observed in those with psychosis suggests that specific cognitive phenotypes may reflect differing causative mechanisms. As such, decision-making performance could identify subgroups of individuals with more severe cortico-striatal dysfunction and help to predict their functional decline. The present work evaluated the relationship between goal-directed action, reversal learning, and symptom profiles in those with psychosis. We assessed decision-making processes in healthy controls (N = 34) and those with persistent psychosis (N = 45), subclassifying subjects based on intact/impaired goal-directed action. Compared with healthy controls (<20%), a large proportion (58%) of those with persistent psychosis displayed impaired goal-directed action, predicting poor serial reversal learning performance. Computational approaches indicated that those with impaired goal-directed action had a decreased capacity to rapidly update their prior beliefs in the face of changing contingencies. Impaired decision-making also was associated with reduced levels of grandiosity and increased problems with abstract thinking. These findings suggest that prominent decision-making deficits, indicative of cortico-striatal dysfunction, are present in a large proportion of people with persistent psychosis. Moreover, these impairments would have significant functional implications in terms of planning and abstract thinking.

Ageing with psychosis - Fifty and beyond.

OBJECTIVE: While there is considerable current emphasis on youth and early psychosis, relatively little is known about the lives of people who live with psychotic disorders into middle age and beyond. We investigated social functioning, physical health status, substance use and psychiatric symptom profile in people with psychotic disorders aged between 50 and 65 years. METHODS: Data were collected as part of the Survey of High Impact Psychosis, a population-based survey of Australians aged 18-65 years with a psychotic disorder. We compared those aged 50-65 years (N = 347) with those aged 18-49 years (N = 1478) across a range of measures. RESULTS: The older group contained more women and more people with affective psychoses compared to the younger group. They were also more likely to have had a later onset and a chronic course of illness. The older group were more likely to have negative symptoms but less likely to exhibit positive symptoms; they also had lower current cognition, compared to the younger group. Compared to the younger group, the older group were more likely to be divorced/separated, to be living alone and to be unemployed. They had substantially lower lifetime use of alcohol and illicit substances, but rates of obesity, metabolic syndrome and diabetes mellitus were higher. CONCLUSION: Our findings suggest that the characteristics of people with psychosis change significantly as they progress into the middle age and beyond. A better understanding of these differences is important in informing targeted treatment strategies for older people living with psychosis.

Characteristics of people on community treatment orders in Australia: Data from the 2010 National Survey of High Impact Psychosis.

OBJECTIVE: Existing evidence on factors associated with community treatment order placement is largely restricted to administrative data. We utilised the data from a large nationally representative sample to compare the demographic, clinical, social functioning, substance use and service utilisation profiles of people living with psychosis under community treatment orders with those who were not. METHODS: Participants were grouped based on whether they had been subject to a community treatment order in the past 12 months or not. We conducted logistic regressions to examine demographic, clinical, social functioning, substance use and service utilisation profiles associated with the two groups. RESULTS: People who had recently been subject to community treatment orders were more likely to be treated with long-acting injectable antipsychotics and lacked insight but were less likely to report suicidal ideation. They also had higher psychiatric inpatient admission rates but a lower frequency of general practitioner visits. CONCLUSION: People on community treatment orders in Australia may differ from those who are not under a community treatment order in their treatment needs. Resources and care provision must match the needs of this particularly vulnerable group.

Improving the mental health of Australians: A renewed call for primary care psychiatry.

OBJECTIVE: To describe different ways to improve liaison between psychiatrists and general practitioners in Australia. CONCLUSION: Strengthening the links between psychiatry and GPs in primary care is an effective approach to improve the mental health of Australians.

Working towards success in the Royal Australian and New Zealand College of Psychiatrists Modified Essay Question Exam.

OBJECTIVE: To describe an approach to support Royal Australian and New Zealand College of Psychiatrists (RANZCP) trainees achieve success in the Modified Essay Question (MEQ) examination. METHOD: Synthesis of the opinion of the authorship encompassing a range of relevant stakeholders, supported by a qualitative content analysis of published examination feedback from the RANZCP Committee for Examinations. RESULTS: In approaching the MEQs, candidates are encouraged to (1) read the scenario and questions carefully, (2) answer questions broadly and with justification, (3) manage time effectively, (4) undertake deliberate practice in preparation, and (5) 'check your own pulse' (i.e. limit the detrimental impact of anxiety on performance). CONCLUSION: Preparing for the MEQ examination through deliberate practice will help candidates become competent psychiatrists. The ability to critically think in clinical practice, a key focus of this assessment, is an essential skill all psychiatrists need to develop and maintain.

Prevalence of diabetes in people with intellectual disabilities and age- and gender-matched controls: A meta-analysis.

BACKGROUND: This meta-analysis aims to: (i) describe the pooled prevalence of diabetes in people with intellectual disabilities, (ii) investigate the association with demographic, clinical and treatment-related factors and (iii) compare the prevalence versus age- and gender-matched general population controls. METHODS: Pubmed, Embase and CINAHL were searched until 01 May 2021. Random effects meta-analysis and an odds ratio analysis were conducted to compare rates with controls. RESULTS: The trim- and fill-adjusted pooled diabetes prevalence amongst 55,548 individuals with intellectual disabilities (N studies = 33) was 8.5% (95% CI = 7.2%-10.0%). The trim- and fill-adjusted odds for diabetes was 2.46 times higher (95% CI = 1.89-3.21) (n = 42,684) versus controls (n = 4,177,550). Older age (R2  = .83, p < .001), smoking (R2  = .30, p = .009) and co-morbid depression (R2  = .18, p = .04), anxiety (R2  = .97, p < .001), and hypertension (R2  = 0.29, p < .001) were associated with higher diabetes prevalence rates. CONCLUSIONS: Our findings demonstrate that people with intellectual disabilities are at an increased risk of diabetes, and therefore routine screening and multidisciplinary management of diabetes is needed.

Characteristics of people on long-acting injectable antipsychotics in Australia: Data from the 2010 National Survey of High Impact Psychosis.

OBJECTIVE: This study investigates (1) the proportion of people with psychosis who are on long-acting injectable antipsychotics; (2) the difference in the demographic, clinical, substance use and adverse drug reaction profiles of people taking long-acting injectables compared to oral antipsychotics; and (3) the differences in the same profiles of those on first-generation antipsychotic versus second-generation antipsychotic long-acting injectables. METHODS: Data were collected as part of the Survey of High Impact Psychosis. For this study, participants with diagnoses of schizophrenia or schizoaffective disorder who were on any antipsychotic medication were included (N = 1049). RESULTS: Nearly a third (31.5%) of people with psychosis were on long-acting injectables, of whom 49.7% were on first-generation antipsychotic long-acting injectables and 47.9% were on second-generation antipsychotic long-acting injectables. This contrasts with oral antipsychotics where there was a higher utilisation of second-generation antipsychotics (86.3%). Of note, compared to those on the oral formulation, people on long-acting injectables were almost four times more likely to be under a community treatment order. Furthermore, people on long-acting injectables were more likely to have a longer duration of illness, reduced degree of insight, increased cognitive impairment as well as poor personal and social functioning. They also reported more adverse drug reactions. Compared to those on first-generation antipsychotic long-acting injectables, people on SGA long-acting injectables were younger and had had a shorter duration of illness. They were also more likely to experience dizziness and increased weight, but less likely to experience muscle stiffness or tenseness. CONCLUSION: Long-acting injectable use in Australia is associated with higher rates of community treatment order use, as well as poorer insight, personal and social performance, and greater cognitive impairment. While long-acting injectables may have the potential to improve the prognosis of people with psychosis, a better understanding of the choices behind the utilisation of long-acting injectable treatment in Australia is urgently needed.

The association between lithium in drinking water and neuropsychiatric outcomes: A systematic review and meta-analysis from across 2678 regions containing 113 million people.

BACKGROUND: Lithium in drinking water may have significant mental health benefits. We investigated the evidence on the association between lithium concentrations in drinking water and their neuropsychiatric outcomes. METHODS: We conducted a systematic review and meta-analysis and searched Pubmed, Embase, Web of Science, PsycINFO and CINAHL up to 19 January 2020, for peer-reviewed research examining the association between lithium concentrations in drinking water and neuropsychiatric outcomes. We used a pairwise analysis and a random effects model to meta-analyse suicide rates and psychiatric hospital admissions. We assessed for publication bias using Egger's test and Duval and Tweedie's Trim and Fill analysis. RESULTS: Twenty-seven studies including 113 million subjects were included in this systematic review. Meta-analysis of 14 studies including 94 million people found higher lithium concentrations were associated with reduced suicide rates (r = -0.191, 95% confidence interval = [-0.287, -0.090], p < 0.001) and meta-analysis of two studies including 5 million people found higher lithium concentrations were associated with fewer hospital admissions (r = -0.413, 95% confidence interval = [-0.689, -0.031], p = 0.035). We found significant heterogeneity between studies (Q = 67.4, p < 0.001, I2 = 80.7%) and the presence of publication bias (Egger's test; t value = 2.90, p = 0.013). Other included studies did not provide sufficient data to analyse other neuropsychiatric outcomes quantitatively. CONCLUSION: Higher lithium concentrations in drinking water may be associated with reduced suicide rates and inpatient psychiatric admissions. The relationship with other neuropsychiatric outcomes and complications remains unclear. Further research is required before any public health recommendations can be made.Trial registration number: The study was registered with PROSPERO, number CRD42018090145.

'Stranger than Fiction': a description of an online essay examination preparation club for Queensland trainees.

OBJECTIVE: To describe an online essay-style examination preparation group. METHODS: The process of the establishment - including recruitment, rules and characteristics - of 'Stranger than Fiction' is outlined. RESULTS: Over the 10-week period, 66 essays were submitted, and 40 essays were marked. Sixteen out of 30 registered candidates submitted at least one essay, and 11 out of 17 registered markers marked at least one essay. CONCLUSION: 'Stranger than Fiction' is a novel approach to create a supportive environment where trainees are given opportunities to practise critical essay questions.

Placing rehabilitation at the core of assertive community treatment.

OBJECTIVES: Assertive community treatment (ACT) teams are increasingly being adapted to suit the needs of consumers who have never experienced long-term institutional care yet struggle to retain community tenure and quality of life due to residual functional disabilities associated with severe mental illness. Support needs can be provided by the growing disability support sector but recovery-orientated rehabilitation services delivered by specialist rehabilitation clinicians are also required. The Mobile Intensive Rehabilitation Team (MIRT) within the Metro South Addiction and Mental Health Service has adapted the ACT model to deliver assertive outreach that aims to work collaboratively with the person and their chosen supports to improve their function and their sense of self-efficacy in illness self-management. We described the characteristics of the consumers referred to MIRT over a 20-month time period, and reported on on their discharge location. CONCLUSION: After two years with MIRT, half the participants were discharged out of case-management. Being on clozapine was a barrier to discharge from case-management despite functional improvement. Psychiatric hospitalisations predicted longer duration working with MIRT.

Preferences of people with mental illness for engaging in exercise programs under COVID-19 restrictions.

OBJECTIVES: People with mental illness may be vulnerable to decline in mental health and reduced physical activity because of the COVID-19 pandemic and associated restrictions. The aim of this study was to inform the design of physical activity interventions for implementation under these conditions to improve/maintain well-being and physical activity in this population. METHODS: People with mental illness who had participated in a physical activity program prior to the pandemic were invited to complete a survey about the impact of COVID-19 on mental health and physical activity and their preferences for engaging in a physical activity program under pandemic-related restrictions. RESULTS: More than half the 59 respondents reported worse mental health and lower physical activity during the pandemic. The preferred format for a physical activity program was one-on-one exercise instruction in-person in a park. Program components endorsed as helpful included incentivization, provision of exercise equipment and fitness devices, and daily exercise programs. About a third of the participants reported limitations in using technology for a physical activity program. CONCLUSIONS: In-person exercise support is preferred by people with mental illnesses during pandemic-related restrictions. Enablement strategies such as providing equipment and self-monitoring devices should be utilized; assistance may be needed to incorporate the use of technology in exercise programs.

A comparison study of three physical activity measurement tools examining acceptability in people with psychosis.

OBJECTIVE: To compare the acceptability of three distinct physical activity measurement tools in people with psychosis: an objective measurement tool, a self-report measure, and an exercise capacity test. METHODS: We measured the completion rate for each measurement tool. Participants rated the ease/difficulty of each measure using a 7-point Likert scale. Participants were also asked to rank the three tools in order of the ease of use. RESULTS: Sixty-six per cent (46/69) of participants completed all three assessment tools, and 60.9% (42/69) completed the acceptability questionnaire. The majority of the participants found it easy to complete all three measurement tools. The majority (52.8%) of the participants ranked the objective measurement tool as the easiest to use. CONCLUSION: All three measures were acceptable to people with psychosis, but objective measurement tools may be easier to use.
