Reducing mental health stigmatisation among healthcare workers and students using a virtual reality protocol: the VIRTUS protocol, a randomised controlled trial

Introduction Schizophrenia is a chronic psychiatric disorder, frequently associated with stigma, including within healthcare settings that significantly impairs quality of life and may exacerbate symptoms. Virtual reality (VR), as an immersive tool, may allow healthy individuals to experience the first-person perspective of a patient experiencing psychotic symptoms. VR exposure may facilitate perspective-taking, foster empathy and help reduce stigma. However, the findings remain incomplete, with considerable variation between protocols and no data on implicit stigma. Here, we present a study…

Is neglect different? Social determinants of child protection plans by recorded maltreatment type in England: a longitudinal ecological study, 2014/2015-2022/2023

Objectives Neglect is the leading cause of acute child protection interventions across high-income countries. In England, reducing the number of children subject to these interventions is a policy priority. However, limited evidence on the health and social factors driving recent trends in neglect constrains effective prevention. We aimed to assess the associations of area-level adult mental health, child poverty and employment, with recorded neglect, and to compare these associations with those observed for other forms of maltreatment. Design Longitudinal ecological study using panel data…
