Trustworthiness measures.

Strategy	Criteria
Credibility	The researchers ensured triangulation of data using in-depth, individual interviews and field notes written during data collection, and the researcher’s positioning prior to data collection. Member checking, independent re-coding and ongoing reflection were conducted. An audit trail was composed by the researcher, consisting of the researcher’s journaling, field notes and transcriptions
Transferability	The background information and contextual elements relevant to this study were explored and described in relation to emergency care personnel. The applicable settings were provided and described in detail to promote an assessment of transferability of findings. The method of sampling, data collection and analysis has been described in detail to promote reader evaluation for transferability of the research.
Dependability	The researchers recorded a detailed description of data gathering, analysis and interpretation referenced against accepted practices, which included data triangulation, independent re-coding and purposive sampling. These activities also generated an audit trail available for verification.
Confirmability	The researchers ensured triangulation of data (in-depth interviews, field notes and researcher positioning), while also ensuring member checking and ongoing reflection throughout data gathering and analysis. These activities also generated an audit trail available for verification
