The gold standard of care for anxiety and OCD is cognitive behavioral therapy (CBT) — a structured, evidence-based approach that targets the thoughts and behaviors maintaining the problem. CBT helps children and families understand what's keeping anxiety going and build the skills to respond differently.
For OCD specifically, the most effective form of CBT is exposure and response prevention (ERP). ERP works by gradually exposing a child to the thoughts or situations that trigger obsessions, while supporting them to resist the compulsion that usually follows. Over time, this breaks the cycle and reduces the power OCD has over daily life.
