Current research has suggested that college student-athletes are at an increased risk for experiencing mental illness but utilize mental health support services at a lower rate than the general college student population. Stigma toward mental illness has been identified as a factor that can influence student-athletes' decision to utilize mental health support services. The aim of this study was to analyze the relationships between the demographic variables of socioeconomic status, sport played, class, race and gender and levels of stigma toward mental illness and peers that utilize mental health support services. This study also investigated college student-athletes' perceived attitudes toward the benefits and barriers to utilizing mental health support services. The participants in this study were 141 NCAA student-athletes who completed an online survey assessing stigma and attitudes toward peers that utilize mental health support services. Follow-up interviews were conducted with seven participants to gain a deeper understanding of the salient attitudes toward the benefits and barriers to utilizing mental health support services. Analyses were conducted to identify relationships between demographic variables and high stigma levels. Results indicated that there was a significant relationship between sport played, class, and gender and stigma levels within the sample. Also, qualitative analysis indicated that self-awareness was identified as a perceived benefit to utilizing mental health support services, but mental health illiteracy, fear of being labelled, and stigma were perceived barriers to utilizing mental health support services in this sample. Findings from this study have implications for how college athletic departments deliver effective mental health support programs to their student-athletes.
