Discriminant effectiveness of psychological state measures in predicting performance outcome in karate competition.
Male Shotokan karate players (karateka) (N = 208) completed the Competitive State Anxiety Inventory-2 and the Profile of Mood States about 40 minutes before a competition. Single-factor multivariate analysis of variance of preperformance mood and anxiety scores indicated significant differences between winning and losing competitors. Winners scored higher on Vigor, Anger, and Self-confidence, and lower on Tension, Depression, Fatigue, Confusion, Cognitive Anxiety, and Somatic Anxiety. Discriminant function analysis showed that 91.96% of participants could be correctly classified as winners or losers on the basis of preperformance mood scores. This figure rose to 93.47% when scores on the anxiety subscales were also included in the discriminant function analysis. Anxiety scores alone produced 78.89% discrimination. Mood profiles for winning karateka were in line with the "mental health" profile of Morgan except for above-average scores on Anger. This result supports the view of McGowan and Miller that anger may facilitate performance in karate competition. The capacity of measures of psychological state to discriminate performance exceeds previous reports, suggesting that karate performance may be exceptionally mood-dependent. These results suggest that interventions which increase scores on Vigor and Anger and reduce scores on Tension, Depression, Fatigue, and Confusion may be particularly efficacious for Shotokan karate performance.
