Simulation training is an effective teaching tool enabling learners to gain a subjective understanding of a range of skills. Our aim in this study was to pilot and evaluate a newly designed simulation of auditory hallucinations as a future training tool for clinicians. This was a mixedâmethods study in two parts. In Phase 1, trainee and qualified clinical psychologists (NÂ =Â 25) attended the Londonâbased immersive art exhibition, Altered States of Consciousness, which included an auditory hallucinations simulation. The exhibition aimed to improve understanding of what it feels like to hear voices by providing members of the public with an individualized simulation of auditory hallucinations. Participants completed pre/postâexhibition measures of their mood and attitudes towards auditory hallucinations and other unusual sensory experiences. In Phase 2, a subgroup of Phase 1 participants (NÂ =Â 15) took part in a semiâstructured interview and completed the postâexhibition questions again approximately 6Â months later. Postâexhibition, there were significant increases in understanding what it feels like to hear voices (large effect), compassion towards people who hear voices (large effect), and comfort talking to people who hear voices (medium effect). Scores were partially maintained at followâup. Participants reported that the simulation provided numerous benefits to their training and clinical practice, including increases in subjective understanding, compassion, and confidence, and suggested several future training applications for the simulation, including with a range of health care professionals. Therefore, we conclude that this simulation has potential for training clinical psychologists and other health care professionals who work with people who experience auditory hallucinations.
