Table 7 Treatment of qualitative data

Participants will be asked to give their written consent for interviews to be audio recorded

Interviews will be conducted at a time convenient for participants, usually in their home

Interviews will be transcribed verbatim, anonymised, and cross-checked for quality

Field notes will be written immediately following interviews to note unrecorded discussion and reflect on key themes

The main themes will be independently coded across a sample of interviews by two researchers using Nvivo 10

A coding frame will be agreed by two researchers

All data will be coded using this coding frame and further additions/adaptions will be discussed

Themes will be summarized using the one sheet of paper method (OSOPs) [40]

Analysis of themes will be developed through writing and wider discussion with the process team
