Regressing team performance on collective efficacy: Considerations of temporal proximity and concordance

The purpose of this study was to determine to what degree collective efficacy judgments based on summative team performance capabilities exhibited different levels of prediction for three additive intervals of team performance in women's ice hockey. Collective efficacy beliefs of 12 teams were assessed prior to Friday's game and Saturday's game for at least 7 weekends. Questionnaires were completed within 24 hr before each game. Performance indicators were obtained from www.college-hockeystats.com. Data were split into two clusters, Study 1 and Study 2, and were subjected to multilevel modeling. Collective efficacy based on summative team performance capabilities was a statistically significant predictor of team performance at each of the three additive team performance intervals in both Study 1 and Study 2. The magnitude of this relationship did not change significantly as the temporal proximity between the efficacy and performance measures decreased, or, as the concordance (to be defined in the Introduction section) of the two measures increased.
