This study assessed the extent to which a one-time experiential intervention improved intercultural awareness and sensitivity among first-year medical students. The students participated in group activities in which they shared personal experiences, solved a hypothetical problem, and engaged in team building exercises. Post-intervention, students reported less intercultural awareness, but a greater commitment to improving the intercultural climate of the medical school and an increased willingness to work in diverse groups during their medical training. The results of the study suggest that experiential interventions may provide an important complement to didactics around issues of intercultural awareness and sensitivity with medical students. Importantly, experiential interventions must provide students with sufficient time to reflect upon and discuss feelings, thoughts and attitudes that emerge during this kind of intercultural awareness training.
