FearFighter is a web-based program that uses the principles of Cognitive Behavioral Therapy (CBT) to help users overcome phobias and panic attacks. It guides users through a step-by-step process of gradual exposure to your fear. It also teaches skills for relaxation and coping in the moment. When completed, this process should allow the user to face their fears without experiencing overwhelming anxiety. While FearFighter can be used with the assistance of a mental health professional, it may be particularly useful for individuals who do not have access to more traditional mental health services. Additionally, FearFighter has been approved by the National Institute for Health and Care Excellence (NICE) in the UK, and has also become eligible for third-party reimbursement. Both of these achievements usually come only after a treatment has been validated by very high quality research.
