Supplementary file 1_Holding collaboration together: a community response using a violence threat and suicide prevention protocol.docx

This article presents qualitative findings from a larger sequential mixed-methods study of Strathcona County’s Violence, Trauma, and Suicide Prevention (VTSP) Protocol.

The VTSP Protocol is a coordinated community framework designed to address youth mental health, community safety, and wellbeing in Alberta, Canada. The larger study combined social network analysis with qualitative inquiry; this article reports on the qualitative strand, which comprised 12 semi-structured interviews with key stakeholders purposively sampled from across the VTSP network. Thematic analysis of interview transcripts identified four interwoven themes that together describe the relational, communicative, and capacity-building labours through which the protocol is sustained: leadership as relational infrastructure, shared processes and communication structures, cross-sectoral relationships and joint purpose, and capacity building and shared language.
