Combining PPI with qualitative research to engage ‘harder-to-reach’ populations: service user groups as co-applicants on a platform study for a trial

Table 6 Qualitative research

Observations	Researchers observed the groups on a number of occasions. HM attended Group 1 during eleven separate visits and participated in three social events, using an ethnographic approach. PH observed at two visits. GT visited Group 2 four times. NC observed and assisted GT at one meeting. Reflexive diaries were kept by all researchers with notes being shared within the research team.
Interviews	Formal individual interviews were undertaken with two members of Group 2 using the study participant information sheet and consent forms, following the study protocol. [34]
Focus groups	Formal focus groups were undertaken twice with members of Group 1 (n = 5; n = 5) and once with members of Group 2 (n = 4) using the study participant information sheet and consent forms, following the study protocol. [34]

In addition, qualitative interviews for this study were undertaken with 88 pregnant women/recent mothers/partners, 53 service providers, 24 experts/decision-makers and 63 conference attendees [26]
