Discussions about mental health's impact on student-athletes continue to increase in collegiate athletics. As leaders, college coaches play an integral part in supporting student-athletes. In this leadership role, coaches must have the proper knowledge and skills to support their student-athletes' mental wellness. The purpose of the current research was to evaluate coaches' mental health literacy before and after watching the intervention videos. In addition, coaches' mental health literacy was also assessed based on their gender, conference affiliation, and years of experience, to support student-athletes' mental wellness. A total of 34 coaches from two National Collegiate Athletic Association DII conferences (PBC n=7, GSC n=27) participated in the research to evaluate their mental health literacy. The 4-week study used a quantitative approach, a quasi-experimental method, and a nonrandomized pretest-posttest design. The independent variables included coaches' gender, conference affiliation, and years of coaching experience. The covariate was the Coaches' Mental Health Literacy survey pretest scores. The dependent variable was the coaches' mental health literacy posttest scores obtained from the Coaches' Mental Health Literacy survey. Two mental health videos from the National Collegiate Athletic Association Sport Science Institute were used as the intervention to improve coaches' mental health literacy. A paired samples t-test was used to evaluate coaches' mental health literacy based on the interventions provided. The paired samples t-test results indicated a significant decrease in coaches' mental health literacy after engaging in the intervention videos. A Quade's rank ANCOVA was used to evaluate each independent variable on Coaches' Mental Health Literacy posttest scores after controlling for Coaches' Mental Health Literacy pretest scores. After adjusting for the Coaches' Mental Health Literacy pretest scores, there were no significant differences in coaches' mental health literacy between any of the three independent variables of mental health literacy before and after the intervention videos were watched. Coaches' mental health literacy did not improve after the intervention. Limitations such as the spring semester, communication, and duration of the survey are discussed, along with recommendations for future research.
