Psychometric Scales for Measuring Public Speaking Stress and Anxiety: A Comprehensive Review

Abstract

Public speaking anxiety (PSA) is the most prevalent and debilitating type of social anxiety, limiting academic performance, work attendance, and social involvement. Objective: This narrative review addresses the psychosocial basis of PSA and summarizes psychometric and biological strategies to capture the stress and anxiety that arise from public speaking. According to contemporary theoretical models, specifically cognitive-behavioral, evolutionary, and acceptance-based perspectives, PSA is a multidimensional condition that is characterized by maladaptive cognitions, avoidance, and sympathetic arousal. Standard test tools, including the Personal Report of Communication Apprehension (PRCA-24), the Personal Report of Public Speaking Anxiety (PRPSA), the Social Avoidance and Distress Scale (SADS), the Fear of Negative Evaluation Scale (FNE) and the Brief Fear of Negative Evaluation Scale (BFNE), have played a critical role in the evolution of research on PSA. Conversely, the majority of these measures provide only minimal contextual specificity and have not necessarily been extensively validated across various cultural contexts. Newer tools have greater sensitivity to performance-related situations and cognitive self-evaluations throughout the speaking tasks [38, 39]: for example, Public Speaking Anxiety Scale (PSAS) Public Speaking Class Anxiety Scale (PSCAS) , Self-Statements During Public Speaking Scale (SSPS), Liebowitz Social Anxiety Scale (LSAS), Social Phobia and Anxiety Inventory (SPAI). Besides the subjective self-report instruments, biological assessment techniques offer objective data related to the physiological correlates of public speaking anxiety. Among these are cardiovascular monitors, electrodermal activity, neuroendocrine profiling, and other similar multimodal indices, acquired via wearable sensor technologies. Combining physiological indicators with psychometric assessments may enhance diagnostic specificity, which may in turn help to elucidate biological mechanisms and allow for more tailored interventions. Standardization of biological reference ranges and assessing their responsiveness to therapeutic approaches should offer further opportunities to optimize treatment. Future research is called upon to establish culturally appropriate, multimodal measures able to assess anticipatory anxiety, in-task experience, and post-event processing. More attention should be paid to stress profiles predicted by various speaking contexts and to the delivery of just-in-time adaptive interventions. This review emphasizes the importance of multimethod assessment frameworks which integrate self-report, behavioral, and physiological measures of public speaking anxiety to enhance our ability to accurately identify, manage, and effectively treat individuals suffering from public speaking anxiety.
