Data analysis
Data collection and analysis ran iteratively, and in parallel. NVivo 12
(QSR International, Melbourne, Australia) was used to organise data and
support analysis. Data were analysed inductively with all data from each
case read together to identify and organise codes. Codes were developed
and refined reflecting text or expressions that captured significant
views in the data. Codes were then grouped to reflect developing themes,
with code descriptions and sample quotes assigned. Case summaries were
developed and reviewed using constant comparative techniques to assess
whether and how to expand or merge themes. Double coding of a proportion
of interview transcripts was undertaken by JW. Commonality and variances
across cases were discussed between the researchers and used to further
shape evolving themes and sampling.
