The goal was to investigate a potential causal pattern between the motives of sport spectators and team identification by using a cross-lagged panel design. Questionnaires were completed by 229 participants at the beginning and end of one NCAA (National Collegiate Athletic Association) college football season for 4 mo. in the USA. The questionnaire included three items for each motive (Social Interaction and Entertainment), three items measuring team identification, and demographic items. The relation of Entertainment at Time 1 to team identification at Time 2 was larger than the relation of team identification at Time 1 to Entertainment at Time 2. This suggests that the motivation of Entertainment may lead to the formation of team identification more than team identification leads to Entertainment. However, the motive of Social Interaction did not show the same pattern. As results of this study suggested some spectator sport motives might lead to identification with a team, the hypothesis that all motives would be the basis of team identification might not be correct.
