Around 100 000 people live in mental health supported accommodation in England, at considerable cost to the public purse, but there is little evidence to guide investment in the most effective models. We consider the various barriers to research in this field and offer suggestions on how to address them.

Mental health-related multimorbidity can be considered as multimorbidity in the presence of a mental disorder. Some knowledge gaps on the study of mental health-related multimorbidity were identified. These knowledge gaps could be potentially addressed with real-world data.

In the healthy brain, homeostatic balance between excitation and inhibition maintains neural stability. Reduced inhibition may explain shared symptoms observed in autism and psychosis. Here we review evidence suggesting that altered levels of gamma-aminobutyric acid (GABA) may underlie both disorders, providing a potential cross-diagnostic therapeutic target.

Mindfulness-based therapies are increasingly available for a range of mental disorders, such as depression and anxiety. However, there remain concerns that mindfulness has the potential to exacerbate psychosis, despite a growing body of literature demonstrating effectiveness. These concerns may relate to long-standing perceptions about the suitability of offering psychological therapies to people with psychosis.

People with neurodevelopmental disorders often present with challenging behaviours and psychiatric illnesses. Diagnosis and treatment require patients, families and healthcare professionals to work closely together in partnership, acknowledging their respective areas of expertise. Good treatment outcomes should also be underpinned by robust research evidence. Key research priorities are highlighted.

Although long-term outcomes of girls with attention-deficit hyperactivity disorder are understudied, high risk for adolescent and young-adult self-harm is salient. We present data on predictors and mediators of such risk, highlighting a recent dual-process model involving trait impulsivity plus family- and peer-related contributors. We conclude with recommendations for assessment and preventive intervention.

Engagement with natural environments is associated with improved health and well-being in the general population. This has implications for mental healthcare. Implementation of targeted nature-based interventions (green care) meets recovery needs and would enable research to develop, clarifying what works best for whom.

The new Sentencing Council Guideline on sentencing offenders with mental disorders, effective from 1 October 2020, is essential reading for all psychiatrists who give evidence in the criminal courts, revealing something of required judicial thinking, our common ground on public safety concerns but differences in focus on culpability and punishment.

The World Health Organization has developed training material to support its QualityRights Initiative. These documents offer excellent strategies to limit coercion. However, the negative portrayal of psychiatry, the absolute prohibition on involuntary treatment and the apparent acceptance of the criminalisation of individuals with mental illness are causes for concern.

Women in academic publishing and academic psychiatry face many challenges of gender inequality, including significant pay differentials, poor visibility in senior positions and a male-dominated hierarchical system. We discuss this problem and outline how the BJPsych plans to tackle these issues it in its own publishing.

In this editorial we define ‘productivity’ and ‘efficiency’ in a mental health service context, outlining the key challenges to measuring these in practice. We attempt to bring clarity of thought to this often debated, but rarely researched area.

Children and adults with neurodevelopmental disorders make up an estimated 10% of the population. Addressing health inequalities and poorer life outcomes is essential to deliver better quality care. Two parent-carers working in national roles in England suggest ways to increase understanding and work together in coproduction to achieve this.
