This study examines intensity and direction of competitive state anxiety symptoms, and the interactive influence of anxiety subcomponents upon netball performance. Netball players (N = 45) completed the modified Competitive State Anxiety Inventory-2 (CSAI-2) and a retrospective performance measure over a season, utilizing an intraindividual design. The modified CSAI-2 includes a direction scale assessing the facilitative or debilitative interpretation of the original intensity symptoms. Although the facilitative influence of anxiety upon performance did not emerge directly through the direction scale, a significant interaction emerged from the two-factor Cognitive Anxiety × Physiological Arousal quadrant analyses, suggesting that anxiety may enhance performance, as proposed by catastrophe model predictions. Findings also highlighted the importance of self-confidence for possible inclusion in higher order catastrophe models.
