The purpose of this study was to analyze the meaning of acceptance of perfectionism as perceived on KLPGA players. The study participants were selected using purposeful sampling to include three first-tier tour players who are full members of the KLPGA and have won tournaments. The data collection were conducted through interviews, and the collected data were analyzed through qualitative case study analysis to understand the meaning of the case contents in the context of the meaning of the case. The results of the analysis are as follows. First, the KLPGA players' perfectionist tendencies were expressed by the environment of sports competition, and tended to change depending on personal and environmental factors, depending on the standards that imposed goal setting. Second, as their performance increased, their obsession with perfection increased, and they experienced negative emotions and obsessive-compulsive symptoms as they negatively perceived mistakes or failures. Third, although the athlete continued to set higher goals and perfectionist tendencies in order to meet socially imposed demands and expectations, he was able to positively negotiate the meaning of perfection through internal negotiation. However, case C showed difficulties with positive internal negotiation, which has implications for the issue of maladaptive reactions to perfectionism in athletes.
