Trait aggressiveness and hockey penalties: predicting hot tempers on the ice.

Previous studies examining the validity of measures of trait aggressiveness either have been retrospective studies or have used laboratory aggression as the criterion behavior. Can a measure of trait aggressiveness predict nonlaboratory physical aggression? The Physical Aggression subscale of the Aggression Questionnaire was completed by 91 high school hockey players prior to the start of the season. At the end of the season, these trait aggressiveness scores were regressed on minutes in the penalty box for aggressive penalties (e.g., fighting, slashing, tripping) and minutes in the penalty box for nonaggressive penalties (e.g., delay of game, illegal equipment, too many players). As expected, preseason trait aggressiveness scores predicted aggressive penalty minutes (r = .33) but not nonaggressive penalty minutes (r = .04).
