Overview of data types

Participant group	Data type	Purpose	How data will be obtained
Programme developers	Qualitative semi-structured interviews (group or individual) with demographics form	To examine the rationale behind the programme, how it is supposed to work, the aims and intended outcomes will be undertaken	Programme developer interviews will be held via Zoom at the start of the study (August 2020)
Assistants in medicine	Qualitative narrative group (or individual) interviews with demographics form	To examine the day-to-day lived experiences around the programme outcomes and how they are facilitated (including unintended outcomes), this includes teamwork, preparedness and identities	We will begin with group interviews (time 1) and an invitation to participate in the longitudinal audio diary study. At the end of the assistant in medicine term (December 2020), we will undertake exit interviews as an opportunity for further reflections. We will contact the assistants in medicine when they have transitioned into the workplace full time for a third interview (February–March 2021)
	Longitudinal audio diaries (including midway and exit interview)
	Longitudinal validated questionnaires	To examine constructs over time and the interrelatedness of those constructs (tolerance of uncertainty, stress, profile of mood states, burnout and identity)	Administered two times at the beginning and end of the assistants in medicine term (August 2020 and December 2020)
Assistant in medicine supervisors and team members	Qualitative semistructured interviews (group or individual) with demographics form	To explore in depth their daily experiences of working with the assistants in medicine	(August 2020 to December 2020)
Assistant in medicine supervisors and team members	Surveys	To capture the extent to which participants agree with a set of statements around the Assistants in Medicine Programme (linking with the developing programme theory, in particular focusing on outcomes)	One-off survey including an open-ended section at the end for ‘additional’ information/narratives of experiences (December 2020)
