Tactical populations and other performers who find it difficult to access training often turn to simulation training to adequately prepare, and increasingly are using virtual reality (VR) as a resource. Additionally, groups struggling with fear produced by various aspects of tactical training may find VR, alongside psychological skills training, to be valuable resources to enhance performance. Research has yet to examine the impact of both VR and mental skills training on performance. The survival swimming course at the United States Military Academy, which includes a 6.5-meter tower entry into water in full combat uniform, presents cadets with numerous psychological challenges, especially for those with a fear of heights and/or water. Cadets who struggle in this course risk psychological trauma, debilitated performance across several domains, and in some cases, expulsion from the academy. This study examined the effectiveness of an intervention consisting of VR and mental skills training spanning over the six-week duration of the survival swimming course, using the Heights Interpretation Questionnaire (HIQ), an adapted Athletic Skills Coping Inventory (ASCI), and course grades as dependent variables. No significant change in HIQ was detected; however, the posttest score was negatively correlated with course grades, indicating that individuals with less sensitivity to heights by the end of the semester performed better in the course. A significant increase was observed in total ASCI score and one subscale (Peaking Under Pressure). Additionally, participants who viewed a greater number of mental skills instructional videos achieved higher course grades. These findings have implications for stakeholders at West Point who may seek to incorporate this training into cadet programming so as to improve coping skills and performance within this population. Further, these results may be useful for mental performance consultants looking to replicate this type of intervention to enhance performance for other, similar populations.
