Prevalence data (i.e., data on the prevalence of both treated and untreated psychiatric disorders in the English adult population (aged 16 and over)) is essential in establishing mental health need and unmet need in the population. The latest information on the number of adults with a diagnosable mental health condition (including a breakdown by occupation) was provided by the Adult Psychiatric Morbidity Survey (APMS) in 2014. The commissioning and delivery of the next survey was delayed by the Covid-19 pandemic. We know that services have been reporting increase in demand and changes in the complexity of cases, so it is likely that estimates from that 2014 survey are limited in what they can tell us about current prevalence. DHSC has commissioned the next iteration of the APMS to provide essential data on adult mental health prevalence to inform service planning, commissioning, and improvement. Fieldwork on the APMS is taking place and reporting is planned for early 2025. DHSC will consider the findings of this survey, including in the context of improving the mental health and well-being of agricultural and veterinary communities.
