Half of the 56 subjects (n = 28) performed 15 pre-treatment trials on a stabilometer, then six more with an audience of three faculty (Group 1), the other half performed the same task with no audience (Group 2). Subjects completed the State-Trait Anxiety Inventory prior to and after the treatments. Orthogonal contrasts indicated that Group 1 (audience) post State-anxiety was significantly different from its own pre-State-anxiety and significantly different from Group 2 (no audience) on post-State-anxiety. It was concluded that the State-Trait Anxiety Inventory is an appropriate measure of trait and state anxiety in studies of motor performance.
56名受试者中的一半（n = 28）在平衡仪上进行了15次治疗前试验，然后在三名教员在场的情况下又进行了6次试验（第1组），另一半在没有观众的情况下完成了相同的任务（第2组）。受试者在治疗前后完成了状态-特质焦虑量表。正交对比表明，第1组（有观众）治疗后的状态焦虑与自身治疗前的状态焦虑有显著差异，且在治疗后的状态焦虑方面与第2组（无观众）有显著差异。得出的结论是，在运动表现研究中，状态-特质焦虑量表是测量特质焦虑和状态焦虑的合适工具。
