Developing and Feasibility Testing of a Brief Contact Intervention to Reduce Self-harm Repetition Through Co-design.

The brief contact intervention (BCI) will send out text messages to the participants. The text messages will include caring messages, reminders of appointments, and a link to a web page. The web page is anticipated to include safety planning, volitional helpsheet, and resources information. The text messages are anticipated to send out to the participants on a weekly base for 6 weeks in a row, and then change to monthly reminders. The monthly reminders are anticipated to include caring messages, reminders of appointments, and invitations to encourage the participants to click the previous web links again. The monthly reminders are anticipated to send out to the participants three times in a row. In the final reminder, the participants will be told that this intervention is going to end. In total, the participants will receive 9 texts within 5 months.
