Sports scientists increasingly recognize that performance outcomes are influenced not only by physical fitness but also by an individual’s psychological makeup and sociological profile. This highlights the importance of socio-psychological dimensions in athletic performance. Aronson (1977) ^[1] defined aggression as behavior intended to cause harm or pain, emphasizing the element of intent. This study aimed to analyze aggression differentials among champion and non-champion boxers and male and female boxers. A total of 280 boxers participating in inter-college competitions in northern India were selected through random sampling. Aggression levels were measured using the Aggression Scale developed by Roma Pal and Tasneem Naquavi (1980) ^[4], with a reliability and validity coefficient of 0.78 each.
