Background: Performance anxiety related to nursing simulation can potentially impede student learning. Method: This study employed a randomized control group pretest-posttest design to examine the effect of music listening on anxiety, self-efficacy, and performance among baccalaureate nursing students undergoing simulation testing (N = 38; M-age = 23.05, standard deviation = 3.41). Results: Heart rate, mean arterial pressure, and state-trait anxiety scores were significantly lower in the experimental group, F(3, 35) = 6.55, p = .02, eta(2) = 0.27, whereas instructor performance ratings were significantly higher than the control condition (p = .009). No differences were seen on self-efficacy scores (p = .37). Conclusions: The intervention has the potential to reduce anxiety, improve performance, and facilitate learning in simulation testing experiences.
