Interventions to improve mental health and stress resistance in medical students are needed. A Systematic Review conducted by the author found good evidence for the effectiveness of peer-led interventions for improving mental health amongst students. Therefore, a Randomised Controlled Trial (RCT) was conducted to assess the effectiveness of a peer-led intervention to improve mental health and wellbeing in medical students.    

The Peer Intervention RCT was a 2-arm trial conducted over 6 months with medical students. Peer leaders, selected by students, were trained to lead the intervention of peer-support and peer-taught mindfulness. Students were randomised to intervention or control. Outcome measures included depression (PHQ-9), anxiety (GAD-7), quality of life (LASA), resilience (15 item RS), academic self-concept (PCL) and motivation to learn (MSLQ).     

In total, 275 students were randomised (53% female, mean age 21) and 232 completed 6-months follow-up. There was a wide range of mental health scores at baseline. At 6-month follow-up, there was a trend towards improved mental health scores in the intervention group compared with control but no differences reached statistical significance. There was some evidence of contamination of intervention.

The level of evidence for peer-led interventions in students to improve mental health and wellbeing is promising but higher quality trials are needed, powered to detect likely change allowing for wide variation in mental health profiles. A cluster design is recommended. Peers are capable of delivering effective interventions and peer-led approaches are acceptable. The challenges of conducting a RCT in this area will be discussed.
