Observed Prosocial and Antisocial Behaviors in Male Soccer Teams: Age Differences across Adolescence and the Role of Motivational Variables

This study examined the frequency of observed prosocial and antisocial behaviors in soccer teams, age differences in observed behaviors and motivational variables, and whether motivational variables account for age differences in observed behaviors. Participants were 313 adolescent soccer players, recruited from three age groups: under 13, under 15, and under 17. Each age group was represented by eight teams. Players were filmed during a game and completed questionnaires after the game. Videotaped games were analyzed by two observers, who recorded behaviors for each team rather than each individual player; therefore, all data were analyzed only at the group level. Observed antisocial behaviors were more frequent than prosocial ones. Significant differences were also identified among the three age groups with the oldest group displaying more frequent antisocial and less frequent prosocial behaviors and perceiving a stronger performance climate and a weaker mastery climate in their team compared to the two younger groups. A series of ANCOVAs using motivational variables as covariates indicated that mastery climate followed by performance climate accounted for the largest decrease in the variance of both prosocial and antisocial behaviors attributed to the age group factor. The findings are discussed in terms of their implications for promoting fair play in sport.
