Personal Report of Public Speaking Anxiety (PRPSA)

1. Abstract

The Personal Report of Public Speaking Anxiety (PRPSA) is one of the most widely utilized and psychometrically established self-report self-assessment instruments designed to measure public speaking anxiety and context-specific communication apprehension. Developed by James C. McCroskey in 1970, the scale conceptualizes speech fright as a measurable, trait-like affective and physiological construct characterized by apprehension, autonomic arousal, cognitive disruption, and behavioral inhibition in formal public address contexts. Comprising 34 items administered on a 5-point Likert response scale ranging from 1 (Strongly Disagree) to 5 (Strongly Agree), the PRPSA captures cognitive, physiological, and behavioral dimensions across anticipatory, performance, and post-performance phases of public delivery.

Across five decades of empirical research, the PRPSA has consistently demonstrated exceptional internal consistency, typically yielding Cronbach’s alpha coefficients exceeding .90 (often ranging between .92 and .95), alongside strong test-retest reliability (.84 to .88 over multi-week assessment intervals). Factor analytic investigations demonstrate a dominant general factor reflecting general speech apprehension, accompanied by distinct second-order facets corresponding to anticipatory anxiety, autonomic arousal, and performance dread. Scoring yields a continuous index ranging from 34 to 170, with established normative cutoffs categorizing individuals into low (< 98), moderate (98–131), and high (> 131) public speaking anxiety. The PRPSA remains a foundational benchmark in speech communication instruction, counseling psychology, behavioral therapy, and educational intervention trials evaluating therapeutic regimens such as systematic desensitization, cognitive restructuring, and virtual reality exposure therapy.

3. Authors

The PRPSA was authored by James C. McCroskey, Ed.D. (1938–2012), a prominent scholar in communication studies and Professor Emeritus at West Virginia University. McCroskey served as Chair of the Department of Communication Studies at West Virginia University for over two decades and held previous academic appointments at Michigan State University and Illinois State University.

Dr. McCroskey was recognized as one of the most prolific researchers in the history of the communication discipline, authoring or co-authoring more than 40 books and over 200 peer-reviewed journal articles. His primary scholarly contributions focused on communication apprehension, instructional communication, nonverbal immediacy, and socio-communicative orientation. The seminal validation of the PRPSA was published in Speech Monographs (now Communication Monographs) in 1970 under the title “Measures of communication-bound anxiety.” Throughout his career, McCroskey maintained an open-access psychometric repository at the Department of Communication Studies at West Virginia University (www.jamescmccroskey.com) to advance empirical instructional communication research.

4. Purpose

The primary purpose of the Personal Report of Public Speaking Anxiety is to provide a standardized, psychometrically rigorous, and diagnostically practical measure of public speaking anxiety (frequently referred to historically as “stage fright” or “speech anxiety”). Public speaking anxiety represents a prevalent subtype of performance anxiety and situational fear, manifesting as psychological distress, cognitive incapacitation, and physiological reactivity when an individual anticipates or engages in oral presentations before an audience.

Diagnostic and Educational Screening

In educational and institutional environments, the PRPSA is predominantly deployed as an initial diagnostic screening instrument within university basic public speaking courses, professional communication workshops, and clinical communication clinics. Speech instructors and clinical educators utilize the instrument during the opening sessions of instructional terms to establish baseline levels of speech anxiety among students. Because extreme levels of communication apprehension correlate with severe academic avoidance, course withdrawal, reduced academic self-efficacy, and compromised performance, identifying high-anxiety individuals enables timely pedagogical interventions, targeted exposure regimens, or referrals to campus counseling centers.

Clinical Assessment and Treatment Evaluation

In clinical psychology, behavioral therapy, and psychiatry, the PRPSA serves as a continuous outcome measure to evaluate the efficacy of psychological treatments for social anxiety disorder and performance-only social phobias. Empirical studies frequently employ the scale in pre- and post-test experimental designs to quantify symptom reduction following interventions such as:

• Cognitive Behavioral Therapy (CBT): Assessing the attenuation of catastrophic self-talk, rumination, and irrational beliefs related to public judgment.
• Systematic Desensitization: Evaluating graduated relaxation response conditioning against imagined and real speech delivery hierarchies.
• Virtual Reality Exposure Therapy (VRET): Measuring reductions in subjective distress following repeated exposure to responsive avatar audiences.
• Pharmacological Trials: Investigating the physiological and subjective moderating effects of beta-adrenergic blockers (e.g., propranolol) or serotonergic compounds on speech-induced autonomic arousal.

Theoretical and Applied Research

Within academic research, the PRPSA facilitates the empirical examination of communication phenomena, personality traits, and socio-demographic variables. Researchers utilize the instrument to model structural relationships between speech anxiety and constructs such as communicative competence, emotional intelligence, introversion, self-perceived communication competence (SPCC), and physiological indicators including salivary cortisol and galvanic skin conductance.

5. Psychological Construct

The PRPSA operationalizes public speaking anxiety as a multidimensional, context-bound trait. While Dr. McCroskey defined general communication apprehension as “an individual’s level of fear or anxiety associated with either real or anticipated communication with another person or persons” (McCroskey, 1977), the PRPSA isolates the specific context of one-to-many formal presentations. This construct encompasses three core psychological and somatic dimensions:

1. Autonomic and Somatosensory Reactivity

A central dimension captured by the PRPSA is the perceived hyperactivation of the sympathetic nervous system during anticipation and performance. Unlike generalized trait anxiety measures, the PRPSA explicitly evaluates cardinal somatic manifestations, including cardiovascular acceleration (“My heart beats very fast just as I start a speech;” “My heart beats very fast while I present a speech”), hyperhidrosis (“I perspire just before starting a speech”), motor tremors (“My hands tremble when I am giving a speech”), muscular tension (“Certain parts of my body feel very tense and rigid while giving a speech”), and respiratory rate elevations (“I breathe faster just before starting a speech”). These items register respondents’ acute visceral reactivity, reflecting autonomic fight-or-flight signaling triggered by audience evaluation.

2. Cognitive Disruption and Catastrophic Processing

Public speaking anxiety involves persistent, involuntary disruptions in cognitive processing, working memory capacity, and attentional focus. The cognitive facet of the PRPSA evaluates perceived loss of cognitive control, mental confusion, and performance-related apprehension. Representative indicators include mental disorganization (“My thoughts become confused and jumbled when I am giving a speech”), memory retrieval inhibition (“While giving a speech, I get so nervous I forget facts I really know;” “I am in constant fear of forgetting what I prepared to say”), and persistent rumination over errors (“When I make a mistake while giving a speech, I find it hard to concentrate on the parts that follow”). The scale also captures perceived vulnerability during interactive audience engagement (“I get anxious if someone asks me something about my topic that I don’t know”).

3. Affective Distress and Anticipatory Avoidance

The affective dimension comprises subjective feelings of helplessness, dread, panic, and performance-induced discomfort. The PRPSA assesses both acute distress during delivery (“During an important speech I experience a feeling of helplessness building up inside me”) and prolonged anticipatory distress extending across days or hours prior to the performance (“I have trouble falling asleep the night before a speech;” “I feel tense when I see the words ‘speech’ and ‘public speech’ on a course outline when studying;” “When the instructor announces a speaking assignment in class, I can feel myself getting tense”). Furthermore, the construct includes negative self-evaluative expectations regarding final outcomes (“I do poorer on speeches because I am anxious”). Conversely, positively keyed items capture composure, self-efficacy, and affective enjoyment (“I feel that I am in complete possession of myself while giving a speech;” “I enjoy preparing for a speech”).

6. Theoretical Framework

The conceptual foundation of the PRPSA bridges classical behaviorism, cognitive appraisal models, and evolutionary frameworks of social evaluation.

Behavioral and Conditioning Foundations

When McCroskey formulated the instrument in 1970, communication research was heavily influenced by behavioral learning theory and Joseph Wolpe’s reciprocal inhibition paradigm. Under this framework, speech fright was conceptualized as a classically conditioned emotional response. Stimuli associated with public speaking (such as standing before peers, receiving a syllabus, or experiencing direct eye contact from an audience) serve as conditioned stimuli that elicit sympathetic nervous system activation. Avoidance behavior and performance decrements were understood as negative reinforcement mechanisms designed to terminate emotional discomfort. Consequently, the PRPSA was explicitly constructed to capture conditioned autonomic markers that could be tracked over the course of behavioral deconditioning interventions.

Cognitive Appraisal and Self-Efficacy Theory

Subsequent psychometric and theoretical refinements situated the PRPSA within Richard Lazarus‘s transactional model of stress and coping and Albert Bandura‘s social cognitive theory of self-efficacy. In this framework, public speaking anxiety emerges when an individual engages in a two-stage cognitive appraisal process:

1. Primary Appraisal: The individual perceives the public speaking scenario as a high-stakes evaluative threat to their social standing, self-esteem, or peer status.
2. Secondary Appraisal: The individual evaluates their personal coping resources, speech competencies, and physiological control as inadequate to meet audience demands.

When perceived situational demands exceed perceived personal coping resources, performance anxiety escalates. PRPSA items explicitly operationalize this balance by assessing perceived control (“While giving a speech, I know I can control my feelings of tension and stress”) versus internal helplessness (“During an important speech I experience a feeling of helplessness building up inside me”).

Socio-Evolutionary Perspective on Social Threat

Modern evolutionary psychology contextualizes the construct measured by the PRPSA through the lens of social inclusion and group hierarchy maintenance. Public speaking places the individual in an isolated, vulnerable position under the scrutinizing gaze of conspecifics. Evolutionary psychologists argue that public social scrutiny involuntarily activates ancestral defense mechanisms that safeguard against peer rejection, public humiliation, and subsequent ostracism. The pervasive somatic and cognitive reactions quantified by the PRPSA reflect this acute survival reaction when facing a collective audience.

7. Validity

The PRPSA has undergone extensive psychometric validation across educational, psychological, and clinical domains, establishing strong construct, convergent, discriminant, and criterion-related validity.

Construct and Convergent Validity

Construct validity is substantiated by high statistical correlations with parallel psychometric instruments evaluating social anxiety and communication apprehension. In foundational and subsequent studies, PRPSA scores demonstrate robust positive correlations with:

• The Personal Report of Communication Apprehension (PRCA-24) public speaking subscale (r = .78 to .86), confirming convergence on public performance apprehension.
• The State-Trait Anxiety Inventory (STAI) A-State scale administered immediately prior to public speech delivery (r = .64 to .75).
• The Liebowitz Social Anxiety Scale (LSAS) performance subscale (r = .62 to .71).
• The Social Interaction Anxiety Scale (SIAS) (r = .52 to .60).

Discriminant Validity

Discriminant validity has been demonstrated by examining the PRPSA’s associations with conceptually distinct personal constructs. While the PRPSA correlates strongly with specific performance-related fears, its correlations with generalized neuroticism or trait depression are modest (typically r = .25 to .38). Furthermore, its correlations with measures of non-evaluative communication domains (such as dyadic interpersonal communication or small-group discussion comfort among familiar peers) are substantially lower than its correlation with formal public speaking situations, confirming that the PRPSA isolates formal address anxiety rather than generalized interpersonal aversion.

Criterion-Related and Predictive Validity

Predictive and concurrent validity are supported by studies linking PRPSA scores to real-world behavioral, objective physiological, and observational outcomes:

• Objective Physiological Arousal: High PRPSA scorers exhibit significantly higher heart rate elevations (tachycardia) during anticipation and speech initiation compared to low scorers, as well as heightened salivary cortisol concentrations and prolonged skin conductance response latencies.
• Behavioral Performance Decrements: External raters utilizing standardized behavioral speech evaluation rubrics consistently rate high PRPSA individuals as exhibiting more vocal hesitations, disfluencies, posture rigidity, and reduced eye contact.
• Academic Avoidance: High PRPSA scores correlate significantly with higher rates of course drops in classes requiring public presentations, delays in fulfilling graduation speech requirements, and deliberate avoidance of majors requiring oral presentation milestones.

8. Reliability

The internal consistency and temporal stability of the PRPSA have been confirmed across hundreds of empirical investigations involving diverse student and adult populations.

Internal Consistency

In McCroskey’s original 1970 validation research, the instrument demonstrated an internal reliability coefficient of .94 using the split-half method corrected by the Spearman-Brown formula. Subsequent studies using Cronbach’s alpha have consistently observed coefficients ranging between .92 and .96. The large item count (34 items) combined with balanced cognitive, physiological, and affective items creates high inter-item covariance without redundancy. Typical corrected item-total correlations across the 34 items range from .45 to .78, with very few items falling below the .40 threshold.

Test-Retest Reliability

Temporal stability assessments establish that the PRPSA behaves as a stable trait-like measure in the absence of therapeutic or instructional interventions:

• Over a 2- to 3-week test-retest interval, stability coefficients consistently range between .84 and .88.
• Over a full academic semester (approximately 14 to 16 weeks) in control groups receiving no speech training, test-retest correlations remain high (r = .79 to .83), establishing that the construct remains stable over time unless targeted intervention occurs.

Standard Error of Measurement

With an established standard deviation (SD) of approximately 17.2 to 18.5 and reliability estimates hovering around .94, the Standard Error of Measurement (SEM) of the PRPSA is approximately 4.2 to 4.5 score points. This precision allows researchers and clinicians to establish true change indices and Reliable Change Index (RCI) thresholds when monitoring treatment interventions.

9. Factor Analysis

The dimensionality of the PRPSA has been investigated using both Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA).

Exploratory Factor Structure

Early exploratory factor analyses conducted by McCroskey and subsequent psychometric researchers utilizing principal components analysis and principal axis factoring with orthogonal (Varimax) and oblique (Promax) rotations repeatedly revealed that a single primary unrotated factor accounts for 35% to 48% of the total variance. This dominant eigenvalue confirms the instrument’s operational utility as a unidimensional assessment of general public speaking anxiety. All 34 items display primary factor loadings exceeding .40 on this overarching performance anxiety dimension.

Multidimensional Sub-Facets

When unconstrained multidimensional extractions are examined, the PRPSA reliably resolves into three or four correlated latent factors:

1. Somatic / Autonomic Reactivity: Comprising items 10, 19, 20, 22, 25, and 32. Item loadings on this factor range from .58 to .81, capturing cardiovascular acceleration, hyperventilation, tremor, and muscular rigidity.
2. Anticipatory Anxiety & Avoidance: Comprising items 1, 2, 5, 9, 21, 26, 28, 31, and 33. Item loadings range from .52 to .76, capturing somatic and cognitive distress experienced upon assignment announcements, the night prior, and immediate pre-speech waiting.
3. Cognitive Disruption & Helplessness: Comprising items 3, 13, 14, 23, 27, 29, 30, and 34. Item loadings range from .48 to .74, focusing on memory failure, jumbled thoughts, and catastrophic response to minor errors during speech delivery.
4. Positive Composure / Self-Efficacy: Comprising the reverse-scored items (4, 6, 7, 8, 11, 12, 15, 16, 17, 18, 24). Item loadings range from .45 to .72, capturing emotional control, clarity of thought, and speech enjoyment.

Confirmatory Factor Analysis and Model Fit

Contemporary Confirmatory Factor Analytic (CFA) investigations demonstrate that while a strict single-factor model exhibits borderline goodness-of-fit indices due to method effects related to reverse-worded items, a hierarchical bifactor model or a correlated multidimensional model provides superior fit to empirical data:

• Comparative Fit Index (CFI): .91 to .94
• Tucker-Lewis Index (TLI): .90 to .93
• Root Mean Square Error of Approximation (RMSEA): .048 to .062 (90% CI [.042, .068])
• Standardized Root Mean Square Residual (SRMR): .042 to .053

Because the sub-dimensions correlate substantially with each other (inter-factor correlations typically range between .55 and .78), McCroskey and psychometric consensus recommend utilizing the composite total score for diagnostic, instructional, and clinical research purposes.
