Relationship of personalized jerseys and aggression in women's ice hockey.

The present study examined the relationship between aggression and players' names on uniforms in collegiate women's ice hockey. Aggression was defined as mean penalty minutes per game. Information, i.e., win/loss record, penalties, and names on uniforms, about the 2002-2003 season women's ice hockey team was obtained via e-mail from 53 of 72 (74% return rate) sports information directors (Division I = 23, Division II = 2, Division III = 28). Analysis indicated that teams with personalized jerseys had significantly more penalty minutes per game than teams without personalized jerseys. However, as the majority of the teams with personalized jerseys were Division I teams and the majority of the teams without personalized jerseys were Division III teams, it is unclear whether results were due to personalized jersey or competition level of play.
