Masklophobia: Fear of Masks & Costumes

Masklophobia (also called costume phobia) is a specific phobia characterized by intense, persistent fear of people wearing masks, costumes, or disguises. It falls under “other specified phobia” (DSM‑5: 300.29).

Clinical Features

• Immediate anxiety/panic on exposure (or anticipation).
• Avoidance: Halloween, masquerades, theater, medical settings.
• Physical symptoms: tachycardia, dyspnea, sweating, trembling, nausea.
• Recognition that fear is excessive (in adults).
• Duration ≥6 months; causes functional impairment.

Etiology

• Traumatic conditioning (e.g., frightening masked event in childhood).
• Uncanny valley effect: obscured facial cues impair threat detection.
• Genetic predisposition to anxiety disorders.

Treatment

1. Cognitive‑behavioral therapy (CBT) with exposure: graded exposure to masks/images/videos → habituation.
2. Systematic desensitization with relaxation training.
3. Virtual reality exposure therapy (VRET) emerging option.
4. Medication (SSRIs, benzodiazepines short‑term) adjunctive if severe.

Prevalence

Rare; exact prevalence unknown. Often co‑occurs with other specific phobias or social anxiety.
