This study aimed to investigate the effects of a violence-prevention education program using empathy (VPEP-E) on elementary school students. This quasi-experimental design examined fifth-grade students' (a) empathy level, (b) perception of violence, and (c) permissive and negligent attitudes toward violence, using a pre- and post-test design. A total of 101 students participated: the experimental group (n = 48) received eight sessions of VPEP-E, whereas the control group (n = 53) received violence prevention education through classroom lectures. Significant differences were observed between the groups' empathy level (t = 6.81, p < 0.001), perception of violence (t = 2.79, p = 0.006), and permissive and negligent attitudes toward violence (t = -2.21, p = 0.030; t = -2.02, p = 0.046). Thus, a school-based VPEP-E may help elementary school students. Long-term studies evaluating behavioral changes from VPEP-E implementation are needed for establishing the effects on violent behavior.
