Communication is the cornerstone of mental healthcare. In the UK, many people who will need access to mental health services do not possess English as their first language. In this editorial, we seek to examine current policy and guidance with respect to interpreting in mental healthcare, and explore the benefits and challenges of interpretation and the ethical implications to consider. We focus on how mental health services could better engage with interpreters as cultural brokers to understand cultural expressions of distress. We conclude by suggesting an education and research agenda which could decrease ethnic disparities in mental healthcare.

Aims and method: This study assesses newly qualified doctors' confidence in practising clinical skills related to the assessment and management of mental health conditions and how this correlates with other areas of medicine. We conducted a national survey of 1311 Foundation Year 1 doctors in the UK. Survey items assessed confidence recognising mentally unwell patients, conducting a mental state examination, assessing cognition and mental capacity, formulating a psychiatric diagnosis and prescribing psychotropic medications.
Results: A substantial proportion of surveyed doctors lacked confidence in their clinical skills related to mental health and prescribing psychotropic medications. Network analysis revealed that items corresponding to mental health were highly correlated, suggesting a potential generalised lack of confidence in mental healthcare.
Clinical implications: We identify areas of lack of confidence in some newly qualified doctors' ability to assess and manage mental health conditions. Future research might explore how greater exposure to psychiatry, integrated teaching and clinical simulation might better support medical students for future clinical work.

Summary: This article uses three fictitious case vignettes to raise questions and educate on how clinicians can appropriately approach patients experiencing spiritually significant hallucinations. Religious hallucinations are common but are not pathognomonic of mental illness. They are often intimate experiences for the patient that raise complex questions about psychopathology for clinicians. When assessing a patient with religious hallucinations it is important that clinicians hold at the centre that person's personal experience and create a safe space in which they are listened to and epistemic injustices are avoided. Involvement of chaplaincy services is important not just to support the patient but also to ensure that as clinicians we seek support in understanding the religious nature of these experiences.

This brief commentary reflects on navigating two dangers of historical research into psychiatry: hagiographic representations of psychiatrists; and accusations of their self-interest and oppression of vulnerable people.

Aims and method: This narrative review updates the evidence base for cancer-related post-traumatic stress disorder (PTSD). Databases were searched in December 2021, and included EMBASE, Medline, PsycINFO and PubMed. Adults diagnosed with cancer who had symptoms of PTSD were included.
Results: The initial search identified 182 records, and 11 studies were included in the final review. Psychological interventions were varied, and cognitive-behavioural therapy and eye movement desensitisation and reprocessing were perceived to be most efficacious. The studies were also independently rated for methodological quality, which was found to be hugely variable.
Clinical implications: There remains a lack of high-quality intervention studies for PTSD in cancer, and there is a wide range of approaches to managing these conditions, with a large heterogeneity in the cancer populations examined and methodologies used. Specific studies designed with patient and public engagement and that tailor the PTSD intervention to particular cancer populations under investigation are required.

Aims and method: Non-Western literature on the core competencies of mental health peer supporters remains limited. Therefore, we used a three-round Delphi study with peer supporters, service users (i.e. someone using peer support services) and mental health professionals to develop a core competency framework for peer supporters in the Chinese context.
Results: The final framework included 35 core competencies, the conceptual origins of which were local (14.3%), Western (20%) and both local and Western (65.7%). They were grouped into five categories in ascending peer supporter role specificity: (1) self-care and self-development, (2) general work ethics, (3) work with others, (4) work with service users and (5) peer support knowledge.
Clinical implications: A culturally valid mental health peer support competency framework can minimise role confusion and refine training and practice guidelines. In a Chinese context, peer supporters were valued as generic support companions, whereas functions highlighted in the West, such as role modelling, were perceived as less critical.

Background: Training and practice in neuropsychiatry varies across the world. However, little is known about the experiences and opinions of early career psychiatrists (ECPs) across different countries regarding neuropsychiatry.
Aims and method: To investigate neuropsychiatry training experiences, practices and opinions among ECPs across different countries. An online survey was distributed to ECPs in 35 countries across the world.
Results: A total of 522 participants took part in this study. Responses show that neuropsychiatry is integrated to a variable extent in psychiatric training curricula across the world. Most respondents were not aware of the existence of neuropsychiatric training or of neuropsychiatric units. Most agreed that training in neuropsychiatry should be done during or after the psychiatry training period. Lack of interest among specialty societies, lack of time during training, and political and economic reasons are regarded as the main barriers.
Clinical implications: These findings call for an improvement in the extent and in the quality of neuropsychiatry training across the world.

Electroencephalogram-based evidence was accepted in a UK law court for the first time in 1939. This paper gives an account of that case, not previously clinically reported, and the individuals involved. Why it was not published in the literature at the time is explored and parallels with more recent technologies are highlighted.

Many people like to perceive themselves as better than previous generations: more knowledgeable, moral, tolerant and humane. Values associated with these aspects of ourselves may affect how we understand our professional forebears. In the early 20th century, some psychiatrists adopted new biomedical theories, including focal sepsis and eugenics, which resulted in inestimable harm. Detrimental clinical practices arose and were perpetuated in the context of societal values, medical ethics and other forces within and outside the medical profession. Historical understanding of the processes by which these things took place may help inform debate concerning current and future challenges of providing psychiatric care. The methods by which psychiatrists consider their predecessors may also have a bearing on how psychiatrists of the future will perceive us, the psychiatrists of the 2020s.

Aims and method: Selection into core psychiatry training in the UK uses a computer-delivered Multi-Specialty Recruitment Assessment (MSRA; a situational judgement and clinical problem-solving test) and, previously, a face-to-face Selection Centre. The Selection Centre assessments were suspended during the COVID-19 pandemic. We aimed to evaluate the validity of this selection process using data on 3510 psychiatry applicants. We modelled the ability of the selection scores to predict subsequent performance in the Clinical Assessment of Skills and Competencies (CASC). Sensitivity to demographic characteristics was also estimated.
Results: All selection assessment scores demonstrated positive, statistically significant, independent relationships with CASC performance and were sensitive to demographic factors.
Implications: All selection components showed independent predictive validity. Re-instituting the Selection Centre assessments could be considered, although the costs, potential advantages and disadvantages should be weighed carefully.
