Diagnostic anomalies in social phobia

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Social phobia is a recently defined clinical entity with significant diagnostic overlap.
• Differential diagnosis is complicated by similarities with agoraphobia, panic disorder, stress disorder, and avoidant personality disorder.
• In severe cases, differentiation from schizophrenia may be challenging.

Purpose of the Study:

• To define diagnostic criteria for social phobia.
• To differentiate social phobia from other neurotic disorders.
• To investigate the incidence of primary and secondary social phobia in patients with common neurotic disorders.

Main Methods:

• Prospective study over a 2-year period.
• Inclusion of patients with dysthymia, panic disorder, and generalized anxiety disorder.
• Analysis of social phobia incidence and treatment allocation (benzodiazepine, diazepam).

Main Results:

• Prominent situational fear and avoidance are key diagnostic elements for social phobia.
• Distinguishing social phobia from agoraphobia requires careful attention to the nature of feared situations.
• Twelve percent of patients initially presented with secondary social phobia; over 2 years, 9% had social phobia as a primary diagnosis.
• Social phobia diagnosis was more likely in patients treated with diazepam (p < 0.05).

Conclusions:

• Social phobia can be readily defined and distinguished from other neurotic disorders by focusing on situational fear and avoidance.
• Overlap with avoidant personality disorder presents diagnostic challenges.
• The incidence of social phobia in patients with common neurotic disorders is significant, with potential links to benzodiazepine treatment.
