This study analyzed and compared the psychological competitive abilities of 466 youth soccer players from South Korea ( n = 152), China ( n = 151), and Japan ( n = 163) using the Diagnostic Inventory of Psychological Competitive Ability (DIPCA.3) as the measurement tool. The results revealed significant cross-cultural differences: Chinese players exhibited greater patience (M = 4.42) than South Korean (M = 4.09) and Japanese players (M = 3.94, p < 0.001). South Korean and Japanese players showed significantly higher volition for winning (M = 4.31 and 4.37, respectively) than their Chinese counterparts (M = 3.94, p < 0.001). South Korean athletes also reported the highest levels of confidence (M = 4.29, p < 0.001) and cooperation (M = 4.73, p < 0.001). These findings highlight the need for culturally tailored psychological interventions to optimize coaching strategies across East Asian soccer academies.
