Background
Young people aged 12-25 experience self-harm, but interventions that are both acceptable and effective in reducing self-harm behaviour are rare. Digital interventions can be effective; however, they lack long-term engagement and are not embedded with the voice of young people. The Imaginator intervention is a novel, brief, blended intervention with a co-designed app that uses mental imagery to help young people manage self-harm. Our study aims to explore the acceptability and feasibility of the new Imaginator blended intervention (Imaginator 2.0) with young people.
Methods
We conducted a co-produced qualitative study with a purposive sample of young people who had used the Imaginator 2.0 intervention in West London NHS Trust. We conducted semi- structured interviews online using Microsoft Teams from April 2022 to December 2023. Three young people with lived experience of self-harm (i.e. co-researchers) informed every stage of the research cycle from design to dissemination. One co-researcher was trained in how to conduct semi-structured interviews with young people with mental health difficulties and subsequently conducted three interviews. Themes were constructed across three 2-hour virtual meetings with three co-researchers and the rest of the team. We presented the themes in a co- produced thematic map.
Results
Ten participants were interviewed (all female). There were four themes: Imaginator 2.0 therapy impact, mental imagery efficacy and limitations, app experience and engagement, and Imaginator 2.0 expectations and need for improvement. The app was found acceptable as a support tool around self-harm and a useful addition to therapy sessions. All app functionalities were mentioned as helpful by at least a few participants. Mental imagery was deemed a helpful aspect in reducing self-harm, although it was not always enough in moments of crisis. Overall, participants who experienced Imaginator 2.0 felt it had a strong impact on their emotions and behaviour and appreciated the therapist-patient relationship. Nevertheless, most participants felt that the app needed to be better integrated into the therapy and that app features should have more options for personalisation.
Conclusion
Overall, these findings support Imaginator as a brief, cost-effective early intervention that can be offered to young people when they first access services to help manage and contain self-harm. Our next step will be to conduct a randomised controlled trial (RCT) to compare Imaginator 2.0 to treatment as usual.
