Resilience has gradually gained attention in sport psychology. However, there remains a lack of knowledge on how this psychological characteristic can be developed. The aim of the present study was to evaluate the effectiveness of a pressure training intervention for resilience. In order to develop resilient qualities, the central feature of this intervention was the regular exposure to increased pressure during daily practice. This intervention was set up as a quasi-experimental switching replications design, delivered within an elite female basketball academy. The mixed methods evaluation combined individual and team resilience measures with semi-structured interviews with athletes and coaches. Quantitative results demonstrated that the intervention was effective in reducing team level vulnerabilities, but did not necessarily lead to increased individual or team resilience characteristics. Qualitative evaluations demonstrated that the participants perceived the intervention to be effective in a real-world setting. More specifically, it was believed that the intervention led to increased awareness, emerging leadership, stronger communication channels, and the development and execution of collective plans. Furthermore, the participants addressed potential avenues for intervention improvement. Lay summary This study aimed to test a resilience training intervention based on pressure exposure during practice. Results within a female elite basketball academy indicated that both athletes and coaches believed the team became more resilient to in-game stressors and less susceptible to team level vulnerabilities.
