Social Anxiety Disorder (SAD) symptoms encompass a triad of cognitive, 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 persist 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 adolescence (around age 13), with a lifetime prevalence reaching 7-13%, affecting women more frequently than men.
Core Symptom Categories
- Cognitive (Anticipatory & Post-Event Processing): Individuals engage in maladaptive anticipatory processing—worrying for days or weeks before an event, dwelling on negative outcomes, and generating catastrophic mental images (e.g., “everyone will see how scared I am”). Following social encounters, they experience post-event rumination, a detailed “postmortem” reviewing perceived flaws and past social failures, which maintains the anxiety cycle. Common cognitive distortions include overestimating threat, interpreting neutral cues as negative, and believing anxiety symptoms are visible to others.
- Physiological (Autonomic Arousal): Visible symptoms include blushing (a hallmark response), profuse sweating (hyperhidrosis), trembling, palpitations, dry mouth, nausea, and dizziness. These somatic manifestations often reinforce the fear of public embarrassment, creating a feedback loop that intensifies anxiety.
- Behavioural (Avoidance & Safety Behaviours): Overt avoidance includes skipping social gatherings, refusing to speak in public, avoiding eye contact, or complete social isolation. Safety behaviours—speaking softly, excessive rehearsal, using phones as a distraction—provide temporary relief but perpetuate the disorder by preventing the disconfirmation of fears. Children may express anxiety via tantrums, crying, freezing, clinging, or somatic complaints (headaches, stomachaches) to avoid school.
Diagnostic Threshold & Subtypes
- Duration: Symptoms must persist for ≥6 months
- Impairment: The fear causes significant functional disability (e.g., inability to work, maintain friendships, or attend school)
- Subtypes: Performance-only (anxiety restricted to public speaking or performing) versus Generalised (fear across most social situations, e.g., conversations, eating in public, meeting strangers)
- Insight: Adults typically recognise the fear as excessive; 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).
