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.

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.

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.

A 40-year study of child maltreatment over the early life course predicting psychiatric morbidity, using linked birth cohort and administrative health data: protocol for the Childhood Adversity and Lifetime Morbidity (CALM) study.

BACKGROUND: Child maltreatment is a major public health issue worldwide. Retrospective studies show a strong association between self-reported child maltreatment and poor mental and physical health problems. Prospective studies that use reports to statutory agencies are less common, and comparisons of self- and agency-reported abuse in the same cohort even rarer. AIMS: This project will link state-wide administrative health data with prospective birth cohort data (N = 7223) from Brisbane in Queensland, Australia (including notifications to child protection agencies), to compare psychiatric outcomes in adulthood of agency- and self-reported child maltreatment while minimising attrition bias. METHOD: We will compare people with all forms of self- and agency-reported child maltreatment to the rest of the cohort, adjusting for confounding in logistic, Cox or multiple regression models based on whether outcomes are categorical or continuous. Outcomes will be hospital admissions, emergency department presentations or community/out-patient contacts for ICD-10 psychiatric diagnoses, suicidal ideation and self-harm as recorded in the relevant administrative databases. CONCLUSIONS: This study will track the life course outcomes of adults after having experienced child maltreatment, and so provide an evidence-based understanding of the long-term health and behavioural consequences of child maltreatment. It will also consider health outcomes that are particularly relevant for adolescents and young adults, especially in relation to prospective notifications to statutory agencies. Additionally, it will identify the overlap and differences in outcome for two different sources of child maltreatment identification in the same cohort.

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.

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.

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.

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

Physical activity correlates in children and adolescents, adults, and older adults with an intellectual disability: a systematic review.

PURPOSE: Understanding enablers of and barriers for physical activity (PA) participation in people with intellectual disability (ID) is an essential first step to develop effective interventions. This systematic review examined correlates of PA across the socio-ecological model (i.e., intra-personal, inter-personal, environmental and policy level) in people with ID across the lifespan. MATERIAL AND METHODS: Major electronic databases were searched from inception until 15 February 2021. Keywords included "physical activity" or "exercise" and "intellectual disability" or "mental retardation." A summary coding was used to analyze the data for adolescents (<18 years), adults (18 < 50 years), and older adults (50≤ years). RESULTS: Out of 83 PA correlates, retrieved from 39 studies (n = 26,456), only three consistent (i.e., reported in four or more studies) correlates were identified. In adults, older age (7/11, 64%), more severe ID (9/9, 100%) and the presence of physical mobility problems (3/4, 75%) were associated with decreased PA. From 38 correlates identified, no consistent correlates were identified for children and adolescents and older people. CONCLUSIONS: Despite the abundance of evidence of the PA benefits for people with ID, we only found consistent evidence for three correlates reliably being related to PA in adults with ID. More research, particularly among young and older people is urgently needed.IMPLICATIONS FOR REHABILITATIONMore severe intellectual disability is an important barrier for being active in adults with intellectual disability.Presence of physical health problems is an important barrier for being active in adults with intellectual disability.

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.

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.

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.
