N = 18 (20 began) novice surgeons/UK | • Stress (STAI, heart rate, and salivary cortisol) | • Mental imagery | 5 × 30 min mental practice sessions, each undertaken before performing a surgical procedure on a VR simulator | • Sig lower stress in intervention group than control on average and maximum heart rate and cortisol during intervention measurement points. Sig lower anxiety on STAI in intervention group. However, differences were not significant between the groups by the post measurement time point. • Sig higher mental imagery for intervention than control group | Not reported | Not reported | • ESs and CIs of ESs unable to be estimated • Unclear whether mental training would translate to stress reductions outside of the VR task • No intention to treat analysis conducted |
