BACKGROUND: Research capacity-strengthening is recognized as an important component of global health partnership working, and as such merits monitoring and evaluation. Early career researchers are often the recipients of research capacity-strengthening programmes, but there is limited literature regarding their experience. METHODS: We conducted a qualitative study as part of an internal evaluation of the capacity-strengthening programme of the international HERA (HEalthcare Responding to violence and Abuse) research group. Semi-structured interviews were conducted with group members, and thematic analysis was undertaken. RESULTS: Eighteen group members participated; nine of these were early career researchers, and nine were other research team members, including mid-career and senior researchers. Key themes were identified which related to their engagement with and experience of a research capacity-strengthening programme. We explored formal/planned elements of our programme: mentoring and supervision; training and other opportunities; funding and resources. Participants also discussed informal/unplanned elements which acted as important facilitators and/or barriers to engaging with research capacity-strengthening: English language; open relationships and communication; connection and disconnection; and diversity. The sustainability of the programme was also discussed. CONCLUSIONS: Our study gives voice to the early career researcher experience of engaging with a research capacity-strengthening programme in a global health group. We highlight some important elements that have informed adaptations to our programme and may be relevant for consideration by other global health research capacity-strengthening programmes. Our findings contribute to the growing literature and important discussions around research capacity-strengthening and how this relates to the future directions of global health partnership working.
