Surveys used to measure variables included a 30-item sports participation motivation scale a 30-item "aggression inventory". Reliability and validity studies of the sport participation motive scale were done by Gill et al, and it was determined that Cronbach's alpha coefficients were between 0.30 and 0.78 for the sub-dimensions. The Cronbach's alpha internal consistency coefficient of the aggression scale was calculated as 0.83. According to our findings, there was a moderately positive relationship between assertiveness, which is the sub-dimension of aggression, and competition, and friends, which is the sub-dimension of the motivation to participate in sports. A moderately significant negative correlation was found with the sub-dimensions of aggression and entertainment, which is the sub-dimension of the motivation to participate in sports. A moderately significant positive relationship was found with destructive aggression, which is the subdimensions of aggression, and success and status, and competition, which are the sub-dimensions of participation in sports.
