Calm Harm is an app designed to help manage self-harm. Based on principles from Dialectical Behavior Therapy (DBT), Calm Harm teaches teenagers to resist and manage urges to hurt themselves. In addition to providing basic information about self-harm, Calm Harm includes four modules: ‘Distract’, to focus attention off of the urge; ‘Comfort’, to build positive self-regard and constructive habits; ‘Express’, to communicate negative emotions in more effective ways; and ‘Release’, with alternative behaviors for safely venting an unbearable urge. Each activity ranges from 5 to 15 minutes, and can be extended if the user needs more time to manage the urge to hurt themselves. Calm Harm also has a tracking function that allows users to view their progress and take note of patterns and trends in their thoughts, feelings, and behaviors related to self-harm.
