The aim of the present study was to develop a measure of state anxiety for school physical education. The Physical Education State Anxiety Scale was designed to assess the basic anxiety dimensions plus the related cognitive processes. High school students (n = 631) completed the scale just prior to a test on two track and field tasks, in order to create a stressful condition. Data from the sample were randoml y split in two and subjected to exploratory and confirmatory factor analyses, which supported the proposed three-factor structure of Worry, Cognitive Processes, and Somatic Anxiety. Internal consistency coefficients were acceptable. Moderate correlations among the subscale scores supported its construct validity. Results provide preliminary evidence for validity and reliability.
