Background Suicide in young people is a leading cause of death. Interventions that are reflexive, tailored, and developed in concert with this at-risk population are needed. This study aimed to integrate lived-experience into the design of a suicide prevention intervention delivered by phone to young people post-discharge from an emergency department (ED) for suicide risk or self-harm.

Methods Qualitative study was conducted at the Queensland Children’s Hospital, Brisbane Australia. Four focus groups with young people with lived-experience, parents or carers and ED mental health clinicals were conducted. In total 5 young people with lived-experience of suicidality (17–21 years, Mage = 19.20), 3 parents and carers with a lived-experience of caring for a young person with mental illness, and 10 ED mental health clinicians participated in focus groups. The first phase of qualitative analysis involved a phenomenological analysis and second phase included a deductive content analysis. The paper is following the Consolidated Criteria for Reporting Qualitative Research.

Results First phase, a phenomenological analysis identified three foundational themes to structure future follow-up phone interventions: a person-centred focus, the phone-call dynamic, and the phone-call purpose. Second phase, a deductive content analysis found that participants preferred an intervention that was structured, consistent, and finite. Moreover, an intervention that was authentic, able to facilitate and empower growing independence, and achievable of young people after an ED presentation was desired.

Conclusions Participants expressed their desire for a responsive, structured, and clearly focused phone call that would recognise the young person and parent/carer’s needs while providing tailored support to ease transition from the ED to available community and family led care.
