摘要：AbstractThis study presents the psychometric properties of a rating scale of sportsmanship in tennis competiti ons with young players. A total of 446 players used this scale to asses the games they played during a season (n=223). Analyses confirmed the discriminative capacity both sportsmanship (12) and unsportsmanlike (17) items, and high internal consistency of the overall scale (Cronbach's Alpha = 0,702). Moreover, the analysis made to assess the quality of sportsmanship in several tennis championships shows the scores associated with sportmanship and unsportsmanlike behavior and identify the players with the highest scores and lowest in sportiness, allowing the implementation of preventive actions.
