Clinical Vignette
Patient: "Mr. L," 32-year-old management consultant, referred by company EAP after declining a client-facing presentation role — the third such refusal in 12 months, placing his promotion at risk.
Chief Concern: "I'm terrified of presenting in front of groups. My heart races, my voice shakes, and I go blank. I've passed up three presentation opportunities because I couldn't face it. But outside of presentations, I'm perfectly fine socially."
History of Present Illness: Mr. L has experienced severe anxiety specifically related to public speaking and formal presentations since college (10+ years). When facing a scheduled presentation, he experiences anticipatory anxiety for days beforehand (sleep disruption, rumination about 'freezing,' reviewing slides obsessively). During presentations, he experiences palpitations, voice tremor, sweating, cognitive blanking, and an overwhelming fear of appearing incompetent. He avoids formal presentations whenever possible, delegating them to colleagues or finding excuses. Critically, his anxiety is RESTRICTED to performance situations. He has no difficulty in one-on-one meetings, small group discussions, social gatherings, professional networking events, or conversations with superiors. He is described by colleagues as 'charismatic' in informal settings. He dines in restaurants without anxiety, attends parties, and dates without social discomfort. His fear is exclusively about being evaluated during formal performance (standing before an audience and delivering prepared material).
Past Psychiatric History: No prior psychiatric treatment. Tried a beta-blocker (propranolol) from his PCP before a presentation 2 years ago — found it helpful for physical symptoms.
Family History: No psychiatric history in family.
Mental Status Exam: Relaxed, articulate, engaging during one-on-one interview. Speech fluent and expressive. Mood 'fine outside of presentations.' Affect warm, appropriate. No anxiety symptoms during interview. No depressive symptoms. Insight excellent.
Step 1: Social Anxiety Disorder DSM-5-TR Criteria
Criterion A: Marked fear or anxiety about one or more social situations in which the individual is exposed to possible scrutiny by others.
Marked fear of public presentations specifically. Fear is about being scrutinized and evaluated by an audience. MET.
Criterion B: Fears acting in a way or showing anxiety symptoms that will be negatively evaluated.
Fears voice tremor, cognitive blanking, and appearing 'incompetent' in front of the audience. Specifically fears that visible anxiety will lead to negative professional evaluation. MET.
Criterion C: Social situations almost always provoke fear or anxiety.
Every scheduled presentation provokes anxiety. Anticipatory anxiety begins days before. MET.
Criterion D: Situations are avoided or endured with intense fear/anxiety.
Active avoidance: has declined 3 presentation opportunities in 12 months. Career impact. MET.
Criterion E: Out of proportion to actual threat.
His colleagues describe his informal communication as 'charismatic.' The feared outcome (appearing incompetent) is disproportionate to his actual capability. MET.
Criterion F: Duration ≥6 months.
10+ years. MET.
Criterion G: Clinically significant distress or impairment.
Career advancement blocked by avoidance. MET.
Performance Only Specifier
Fear is restricted to speaking or performing in public. No anxiety in other social situations (one-on-one, small groups, social events, networking, dining). DSM-5-TR specifies 'performance only' when the fear is limited to speaking or performing in public. PERFORMANCE ONLY SPECIFIER APPLIES.
Step 2: Generalized Social Anxiety vs. Performance Only
| Feature | Generalized SAD | Performance Only SAD | This Patient |
|---|---|---|---|
| Social situations feared | Multiple: conversations, eating, working, meeting new people | Only speaking/performing before an audience | Performance only: presentations exclusively |
| Interpersonal comfort | Impaired across social contexts | Normal in non-performance social contexts | Charismatic in 1-on-1 and small groups |
| Dating/friendships | Often impaired | Normal | Normal dating and friendships |
| Onset | Often childhood/early adolescence | Variable, may begin in adulthood | College onset (early adulthood) |
| Treatment response | CBT + SSRI; longer course | CBT focused; beta-blocker as needed | Previous propranolol response |
| Prognosis | Chronic without treatment | Often more responsive to targeted treatment | Favorable with targeted intervention |
Specifier Significance
The performance only specifier identifies a circumscribed variant of SAD with distinct treatment implications. Cognitive-behavioral performance training (exposure to simulated presentations with video feedback) and as-needed beta-blocker use (propranolol 20-40mg before presentations) are effective. Full SSRI may not be necessary for the performance-only subtype.
Diagnostic Formulation
Diagnostic Conclusion
Social Anxiety Disorder, Performance Only (F40.10): All DSM-5-TR criteria met with performance only specifier. Anxiety restricted to public speaking/presenting. Normal functioning in all non-performance social contexts. Ten-year duration with career-limiting impairment. Treatment: performance-focused CBT (simulated exposure, cognitive restructuring of catastrophic performance cognitions, video feedback), as-needed propranolol for acute presentations, consider targeted virtual reality exposure therapy.
Teaching Points
- The performance only specifier is important because it identifies a subtype with different treatment needs. Generalized SAD requires broader social skills training and often SSRI; performance only SAD responds well to targeted exposure, cognitive restructuring, and as-needed beta-blockers.
- Beta-blockers (propranolol 20-40mg taken 30-60 minutes before performance) reduce the peripheral sympathetic symptoms of performance anxiety (tachycardia, tremor, sweating) without cognitive sedation. They are first-line pharmacological treatment specifically for performance anxiety.
- Performance anxiety involves a catastrophic cognitive loop: fear of visible anxiety → increased self-monitoring → detection of anxiety symptoms → intensified fear → more visible symptoms. CBT targets this loop through cognitive restructuring and behavioral experiments.
- Video feedback during exposure therapy is particularly effective for performance anxiety. Patients typically discover that their perceived anxiety (subjective experience of tremor, blanking, sweating) is far less visible to observers than they believe. This disconfirms catastrophic predictions.
- Generalized social anxiety and performance-only anxiety may exist on a spectrum. If performance anxiety generalizes to include fear in other social situations (dining, conversations, meeting new people), the performance only specifier no longer applies and the treatment approach must be broadened.
