Gastrointestinal symptoms, faecal short-chain fatty acids and dietary intake in older adults: the Hordaland Health Study 3.

This multicentre randomised controlled trial uses a two-arm parallel-group design with 1:1 allocation and a control virtual reality (VR) condition. This study combines two previously published VR approaches to test whether a brief, immersive, perspective-taking intervention can reduce stigma toward schizophrenia. The protocol combines self-report questionnaires with a behavioural task to assess both explicit and implicit stigma.
