Braun and Clarke's (2006) six‐phase approach to thematic analysis, including detail of how this was implemented and by whom

Phase	Application of the phases within this study
1. Becoming familiar with the data	The first author conducted the majority of interviews and transcribed the data. Transcripts were repeatedly read, and particular attention was paid to rereading transcripts of interviews that the first author had not conducted.
2. Generating initial codes	The first author coded the data in a systematic fashion across the entire dataset. All interview data that related to the TCC were coded.
3. Searching for themes	Data were coded using NVivo 10 (QSR International's NVivo 10 Software, 2014) to support data management. All significant patterns in the data were noted and initial table of second‐order codes and quotes created. Throughout this and subsequent stages, findings were reviewed for coherence and credibility by D. E. and W. M. and the raw data regularly referred to.
4. Reviewing themes	From the initial table of significant second‐order codes and discussions with D. E. and W. M., candidate themes were identified. These were then refined by referring back to data and codes and by creating a detailed thematic map. Candidate themes were examined to establish whether they were coherent, externally heterogeneous, and had explanatory power.
5. Defining and naming themes	Through examination of the detailed thematic map and further discussions, a more parsimonious list of themes were created. These were refined through peer debriefing and verification with Dr Noke and through a member‐checking group. Dr Noke is a qualitative researcher who was not involved in the study team or PCT research.
6. Producing the report	The report was drafted and feedback obtained from D. E. and W. M.
