A causal variable that, when changed, produces an effect on an event, and which can be used to predict the event. Usually, a number of causal variables contribute to an event. For example, an athlete who is very nervous before competition may have many predictors of his or her anxiety response. The athlete may have a high trait anxiety, may have had bad experiences at other high level competitions, or may be focusing upon negative thoughts. These predictors must be accurately identified before a sport psychologist can help the athlete control his or her anxiety.
