Beating Adolescent Self-Harm (BASH): a randomised controlled trial comparing usual care versus usual care plus a smartphone self-harm prevention app (BlueIce) in young adolescents aged 12–17 who self-harm: study protocol
Abstract
Introduction A mobile app, BlueIce, was codesigned with young people with a history of self-harm to provide them with more accessible and available evidence-based support at times of distress.
A preliminary evaluation found that BlueIce was acceptable, safe and used by young people and helped to reduce self-harm.
The present study is designed to assess the effectiveness and cost-effectiveness of adding BlueIce to usual Child and Adolescent Mental Health Service (CAMHS).
Methods and analysis This study is a single-blind, randomised controlled trial comparing usual CAMHS care with usual care plus BlueIce.
A total of 138 adolescents aged 12–17 with current or a history of self-harm will be recruited through the Oxford Health National Health Service (NHS) Foundation Trust via their CAMHS clinician.
The primary outcome is self-harm at 12 weeks assessed using the Risk Taking and Self-Harm Inventory for Adolescents.
Secondary outcomes include mood, anxiety, hopelessness, general behaviour, sleep and impact on everyday life at 12 weeks and 6 months.
Health-related quality of life and healthcare resource utilisation data will be collected at baseline, 12 weeks and 6 months.
Postuse interviews at 12 weeks will determine the acceptability, safety and usability of BlueIce.
