Self-reports are typically used to assess public speaking anxiety. In this study, we examined whether self-report, observer report, and behavioral and physiological reactivity were associated with each other during a speech challenge task. A total of 95 university students completed a self-report measure of public speaking anxiety before and after the speech challenge. Speech duration (i.e., behavioral measure), physiological reactivity, as well as speech performance evaluated by the participants and observers were also recorded. The results suggest that self-reported public speaking anxiety predicts speech duration, as well as speech quality, as rated by the participants themselves and observers. However, the physiological measures were not associated with self-reported anxiety during the speech task. Additionally, we observed that socially anxious participants underrate their speech performance in comparison to their observers’ evaluations.

自我报告通常用于评估公开演讲的焦虑。在这项研究中，我们检查了自我报告、观察者报告以及行为和生理反应在言语挑战任务中是否相互关联。共有 95 名大学生在演讲挑战前后完成了公开演讲焦虑的自我报告测量。还记录了参与者和观察者评估的言语持续时间（即行为测量）、生理反应性以及言语表现。结果表明，自我报告的公开演讲焦虑可以预测演讲持续时间以及演讲质量，由参与者自己和观察者评定。然而，生理测量与言语任务期间自我报告的焦虑无关。此外，
