Analysis
The interviews were audiorecorded, transcribed verbatim by a transcription company, and the transcripts checked and anonymised. The data was analysed thematically using NVivo (version 11) to retrieve and organise the data. The researchers read and re-read the transcripts, undertook systematic coding of the data, and established a coding framework. They explored the relationships between codes, leading to the development of categories (provisional groups of codes) and eventually themes, sharing and discussing these with the wider research team to ensure their trustworthiness.
