Social phobia symptoms, clinically termed Social Anxiety Disorder (SAD), encompass a triad of psychological, physiological, and behavioural manifestations arising from a persistent fear of scrutiny or negative evaluation by others. To meet DSM-5 diagnostic criteria, this intense fear must be present for ≥6 months, be disproportionate to the actual threat, and cause clinically significant impairment in social, occupational, or other vital domains. The disorder typically emerges in early to mid-teens, with a lifetime prevalence reaching up to 12%, affecting women more frequently than men.
Core Psychological Symptoms (Cognitive & Emotional)
- Anticipatory Anxiety: Excessive worry about upcoming social events, often for days or weeks in advance, coupled with post-event rumination, analysing perceived flaws in performance.
- Fear of Scrutiny: Intense dread of being judged negatively, humiliated, or rejected, leading to heightened self-consciousness and a conviction that others will notice one’s anxiety.
- Cognitive Distortions: Overestimation of threat, catastrophizing (“I will faint”), and interpreting neutral cues as definitive proof of negative evaluation.
Physiological Symptoms (Autonomic Arousal)
- Cardiovascular: Palpitations, rapid heartbeat, chest tightness.
- Integumentary & Thermal: Excessive blushing (erythema), profuse sweating (hyperhidrosis), trembling or shaking.
- Gastrointestinal & Respiratory: Nausea, dry mouth, choking sensation, shortness of breath.
- Neurological: Dizziness, lightheadedness, feeling of “mind going blank”.
Behavioural Symptoms (Avoidance & Safety Behaviours)
- Overt Avoidance: Actively skipping social gatherings, refusing to speak in public, avoiding eye contact, or engaging in complete social isolation to escape distress.
- Escape & Safety Behaviours: Leaving situations early, speaking softly, using phones as a distraction, or excessively rehearsing statements to prevent perceived humiliation.
- Somatic Complaints (Pediatric): Children may express anxiety via tantrums, crying, freezing, clinging, or reporting stomachaches/headaches to avoid school or peer interactions.
Diagnostic Threshold & Clinical Features
- Duration: Symptoms must be persistent for at least 6 months.
- Impairment: The fear causes significant functional impairment (e.g., inability to work, maintain friendships, or attend school).
- Subtypes:
- Performance-Only: Anxiety restricted to public speaking or performing (e.g., playing an instrument).
- Generalised: Fear across most social situations (e.g., conversations, eating in public, meeting strangers).
- Distress Recognition: Adults typically recognise the fear as excessive, whereas children may not.
Recognising this symptom triad is vital for differential diagnosis from shyness, as the sheer intensity and life-impairing nature of social phobia necessitate evidence-based interventions like Cognitive Behavioural Therapy (CBT) or pharmacotherapy (SSRIs).
