What is the most effective treatment for obsessive-compulsive disorder (OCD)?

• A. Cognitive behavioral therapy
• B. Serotonin reuptake inhibitors (SSRIs)
• C. Repetitive exposure to fearful stimuli
• D. Benzodiazepines

Answer: (C)

Exposure and response prevention (ERP) is the most effective treatment for OCD. This approach combines gradually exposing the person to feared thoughts, situations, or stimuli with a deliberate prevention of the compulsive rituals that usually follow. Over time, repeated exposure without performing the ritual reduces the anxiety those obsessions trigger and weakens the urge to engage in compulsions. This directly interrupts the OCD cycle and tends to produce durable, substantial improvements, often surpassing what medications alone can achieve. Pharmacotherapy with serotonin reuptake inhibitors can help reduce OCD symptoms and is commonly used, sometimes in combination with therapy, but ERP tends to yield the strongest and most lasting benefit when used as the primary treatment. Benzodiazepines are not effective for treating OCD itself and carry risks such as dependence, so they’re not a preferred long-term strategy. The core idea behind ERP—repeated, controlled exposure paired with resisting rituals—answers OCD more robustly than other approaches listed.
