A Smartphone App (BlueIce) for Young People Who Self-Harm: Open Phase 1 Pre-Post Trial.

Our study has a number of methodological limitations, particularly the absence of a comparison group and a prospective way of assessing self-harm. Nonetheless, our findings are encouraging and suggest that BlueIce, used alongside a traditional CAMHS face-to-face intervention, can help young people manage their emotional distress and urges to self-harm.
