The Calm Harm app by stem4 helps young people resist or manage the urge to self-harm. Developed by Dr Nihara Krause, a consultant Clinical Psychologist, together with ideas from young people, the Calm Harm app uses strategies from Dialectical Behavior Therapy (DBT) to help users learn to identify and manage their ‘emotional mind’, teaching impulse control, emotional regulation and tracking underlying triggers to harmful urges. It is not a substitute for the assessment and individualised treatment of a health/mental health professional.
