Purpose: This study aimed to examine the mediation effects of self-efficacy on the knowledge and compliance of hand washing among cosmetology students. Methods: Data were analyzed using SPSS/WIN 22.0 program. The general characteristics of the subjects, knowledge regarding hand washing, compliance for hand washing, and selfefficacy were analyzed using descriptive statistics. Differences between the variables as per participant characteristics were analyzed using an independent sample t-test. A threestep regression analysis was conducted to verify the effects of self-efficacy in the relationship between hand-washing knowledge and compliance in cosmetology students. Results: Cosmetology students who received education regarding hand washing exhibited higher knowledge and compliance for hand washing. Higher knowledge of hand washing and higher self-efficacy were associated with a higher degree of hand washing; selfefficacy was mediated by hand washing. Conclusion: Self-efficacy mediated the effects of hand washing in students of a cosmetology college. We believe that the provision of education regarding hand washing will increase the efficacy and performance of hand washing in students.
