TL;DR: In this paper, the authors describe and apply a theory from evolutionary psychology, namely social rank theory, to the treatment of command hallucination, and present a treatment protocol developed in accordance with the principles of the theory specifically for CH.
Abstract: Command hallucinations (CH) are a distressing and high-risk group of symptoms that have long been recognized but little understood, with few effective treatments. Research shows that cognitive behavior therapy (CBT) is a promising treatment for hallucinations in general and therefore has a potential role in the treatment of CH. We propose that the development of an effective CBT for CH would be enhanced by a theory specific to this uniquely problematic symptom. In this article we describe and apply such a theory from evolutionary psychology, namely social rank theory, and review recent evidence for its application to hallucinations in general. Second, we present a treatment protocol developed in accordance with the principles of the theory specifically for CH, and describe an illustrative case. Finally, we outline the design and methodology of a new, randomized, controlled trial currently being undertaken to test the efficacy of the treatment. Further developments both in the protocol and in its evaluation are discussed.

TL;DR: To examine the association between mental health‐related stigma and access to care in people experiencing first‐episode psychosis in Birmingham, UK, the researchers examined the impact of stigma on the duration of untreated psychosis, in first-episode psychosis.
Abstract: Aim Mental health‐related stigma is considered a significant barrier to help‐seeking and accessing care in those experiencing mental illness. Long duration of untreated psychosis is associated with poorer outcomes. The impact of stigma on the duration of untreated psychosis, in first‐episode psychosis remains unexplored. To examine the association between mental health‐related stigma and access to care in people experiencing first‐episode psychosis in Birmingham, UK. Methods We collected data on a prospective cohort of first‐episode psychosis. The Stigma Scale was used as a measure of mental health‐related stigma, and duration of untreated psychosis as a measure of delay in accessing care. We performed logistic and linear regression analyses to explore the relationship between mental health‐related stigma and duration of untreated psychosis, adjusting for sex, age, educational level, religion and ethnicity. Results On the 89 participants included in this study, linear regression analysis revealed that overall stigma and the discrimination sub‐factor were significant predictors of longer duration of untreated psychosis, whereas logistic regression identified the disclosure sub‐factor to be a significant predictor of longer duration of untreated psychosis. Conclusions These findings demonstrate that stigmatizing views of mental illness from the patient's perspectives can result in delayed access to care. This emphasizes the importance of tackling mental health‐related stigma to ensure early treatment and improved outcomes for people experiencing first‐episode psychosis.

TL;DR: Training and supporting AO staff to use an integrated treatment approach is well received and produces lasting changes in confidence and practice and whether this can go on to impact upon client outcome is yet to be established.
Abstract: Aim: This study sought to develop a methodology to measure the integration of substance use treatment within five existing assertive outreach (AO) teams in Birmingham, UK. Changes in the way teams approach and discuss drug and alcohol problems amongst clients with severe mental health problems were anticipated. This was assessed at team meetings, through clinical sessions and case notes. The impact of change in team practice was also measured at the level of service users by assessing psychiatric symptoms, engagement, amount of substance used, and conviction ratings of positive substance-related beliefs.Method: Each team were provided with training and supervision to deliver cognitive behavioural integrated treatment (C-BIT). This aimed to increase awareness of the relationship between psychosis and problem substance use and provide skills to manage these difficulties. Data was collected at intervals over a 36 month period.Results: Staff within teams increased in self reported confidence and skills to del...

TL;DR: Prevalent treatment resistance was observed in UK EIP services, but prescription of polypharmacy was much more common than clozapine, which may reflect a missed opportunity to promote recovery in this critical period.
Abstract: Background: Treatment resistance causes significant burden in psychosis. Clozapine is the only evidence-based pharmacologic intervention available for people with treatment-resistant schizophrenia; current guidelines recommend commencement after two unsuccessful trials of standard antipsychotics. Aims: This paper aims to explore the prevalence of treatment resistance and pathways to commencement of clozapine in UK early intervention in psychosis (EIP) services. Method: Data were taken from the National Evaluation of the Development and Impact of Early Intervention Services study (N = 1027) and included demographics, medication history and psychosis symptoms measured by the Positive and Negative Syndrome Scale (PANSS) at baseline, 6 months and 12 months. Prescribing patterns and pathways to clozapine were examined. We adopted a strict criterion for treatment resistance, defined as persistent elevated positive symptoms (a PANSS positive score ≥16, equating to at least two items of at least moderate severity), across three time points. Results: A total of 143 (18.1%) participants met the definition of treatment resistance of having continuous positive symptoms over 12 months, despite treatment in EIP services. Sixty-one (7.7%) participants were treatment resistant and eligible for clozapine, having had two trials of standard antipsychotics; however, only 25 (2.4%) were prescribed clozapine over the 12-month study period. Treatment-resistant participants were more likely to be prescribed additional antipsychotic medication and polypharmacy, instead of clozapine. Conclusions: Prevalent treatment resistance was observed in UK EIP services, but prescription of polypharmacy was much more common than clozapine. Significant delays in the commencement of clozapine may reflect a missed opportunity to promote recovery in this critical period.

TL;DR: It is shown that prediction models can reliably and prospectively identify poor remission and recovery outcomes at 1 year for patients with first-episode psychosis using baseline clinical variables at first clinical contact.
Abstract: Summary Background Outcomes for people with first-episode psychosis are highly heterogeneous. Few reliable validated methods are available to predict the outcome for individual patients in the first clinical contact. In this study, we aimed to build multivariable prediction models of 1-year remission and recovery outcomes using baseline clinical variables in people with first-episode psychosis. Methods In this machine learning approach, we applied supervised machine learning, using regularised regression and nested leave-one-site-out cross-validation, to baseline clinical data from the English Evaluating the Development and Impact of Early Intervention Services (EDEN) study (n=1027), to develop and internally validate prediction models at 1-year follow-up. We assessed four binary outcomes that were recorded at 1 year: symptom remission, social recovery, vocational recovery, and quality of life (QoL). We externally validated the prediction models by selecting from the top predictor variables identified in the internal validation models the variables shared with the external validation datasets comprised of two Scottish longitudinal cohort studies (n=162) and the OPUS trial, a randomised controlled trial of specialised assertive intervention versus standard treatment (n=578). Findings The performance of prediction models was robust for the four 1-year outcomes of symptom remission (area under the receiver operating characteristic curve [AUC] 0·703, 95% CI 0·664–0·742), social recovery (0·731, 0·697–0·765), vocational recovery (0·736, 0·702–0·771), and QoL (0·704, 0·667–0·742; p Interpretation In our machine learning analysis, we showed that prediction models can reliably and prospectively identify poor remission and recovery outcomes at 1 year for patients with first-episode psychosis using baseline clinical variables at first clinical contact.

TL;DR: The TIDieR checklist and guide should improve the reporting of interventions and make it easier for authors to structure accounts of their interventions, reviewers and editors to assess the descriptions, and readers to use the information.
Abstract: Without a complete published description of interventions, clinicians and patients cannot reliably implement interventions that are shown to be useful, and other researchers cannot replicate or build on research findings. The quality of description of interventions in publications, however, is remarkably poor. To improve the completeness of reporting, and ultimately the replicability, of interventions, an international group of experts and stakeholders developed the Template for Intervention Description and Replication (TIDieR) checklist and guide. The process involved a literature review for relevant checklists and research, a Delphi survey of an international panel of experts to guide item selection, and a face to face panel meeting. The resultant 12 item TIDieR checklist (brief name, why, what (materials), what (procedure), who provided, how, where, when and how much, tailoring, modifications, how well (planned), how well (actual)) is an extension of the CONSORT 2010 statement (item 5) and the SPIRIT 2013 statement (item 11). While the emphasis of the checklist is on trials, the guidance is intended to apply across all evaluative study designs. This paper presents the TIDieR checklist and guide, with an explanation and elaboration for each item, and examples of good reporting. The TIDieR checklist and guide should improve the reporting of interventions and make it easier for authors to structure accounts of their interventions, reviewers and editors to assess the descriptions, and readers to use the information.

TL;DR: A heuristic framework for linking the psychological and biological in psychosis is provided and it is proposed that a dysregulated, hyperdopaminergic state, at a "brain" level of description and analysis, leads to an aberrant assignment of salience to the elements of one's experience, at an "mind" level.
Abstract: OBJECTIVE: The clinical hallmark of schizophrenia is psychosis. The objective of this overview is to link the neurobiology (brain), the phenomenological experience (mind), and pharmacological aspects of psychosis-in-schizophrenia into a unitary framework. METHOD: Current ideas regarding the neurobiology and phenomenology of psychosis and schizophrenia, the role of dopamine, and the mechanism of action of antipsychotic medication were integrated to develop this framework. RESULTS: A central role of dopamine is to mediate the “salience” of environmental events and internal representations. It is proposed that a dysregulated, hyperdopaminergic state, at a “brain” level of description and analysis, leads to an aberrant assignment of salience to the elements of one’s experience, at a “mind” level. Delusions are a cognitive effort by the patient to make sense of these aberrantly salient experiences, whereas hallucinations reflect a direct experience of the aberrant salience of internal representations.
