Title: Text Message Intervention to Reduce Repeat Self-harm in Patients Presenting to the Emergency Department
Brief Summary: Between 6% and 30% of people who harm themselves repeat this self-harm within the following 12 months. The investigators know that people who harm themselves are much more likely to commit suicide, but the investigators have no clear evidence about the best way to reduce the likelihood of someone harming themselves again.

Text messaging is now a common form of communication. Previous research has shown us that the investigators can use text messages for different types of health care interventions. Examples of this include reminding patients of medical appointments, delivering test results, to check patient side effects following treatment and to reduce depressive symptoms in patients with depression and alcohol problems. The Samaritans have introduced interactive text messages (where you can have a conversation by text with their service) and have noted an increasing use of this contact with their service.

This research study is taking place to find out if using supportive and interactive text messages can reduce further episodes of self-harm in patients who present to the Emergency Department (ED) with self-harm.

The investigators hypothesize that supportive, informative and interactive text messages delivered to patients discharged from an ED after an episode of self-harm will significantly reduce the frequency and intensity of thoughts of self-harm and self-harming behaviour in patients compared with those receiving only follow-up treatment as usual. A secondary hypothesis is that patients receiving the text messages will report a favourable experience and an overall satisfaction with the system.
