Factors affecting African postdoctoral researcher capacity development within learn-by-doing international research partnerships: findings from the Partnership for Increasing the Impact of Vector Control (PIIVeC)

Introduction The Partnership to Increase the Impact of Vector Control sought to develop the research and leadership capacity of 10 African postdoctoral vectorborne disease scientists via a ' learn-by- doing ' approach. We identified factors that either supported or hindered their development and, drawing on this information, determined key lessons for future programmes with similar objectives. Methods A longitudinal qualitative study encompassing focus group discussions and semistructured interviews conducted with the cohort of African postdoctoral fellows, programme leadership, supervisory and research support staff (N=28). Data analysis was informed by a general inductive approach. Results Numerous supportive and hindering factors were identified. Supportive factors were primarily structural or attitudinal in nature, whereas hindering factors were primarily operational or contextual. None of the supporting or hindering factors were specific to vectorborne disease research. Four key lessons for future programme implementation emerged, including: the value in exposing postdoctoral fellows to a diverse work-mix and training-mix to improve understanding of the broad skillset needed for scientific career advancement; recognising and managing the potentially competing interests of different partnership members to ensure everyone benefits from participation; ensuring equity of opportunity and rewarding engagement; and ensuring flexibility in support provision. Conclusion Our study highlights numerous factors that may be readily incorporated into early career researcher capacity strengthening initiatives based on a learn-by- doing approach. Many of these factors are supported by a growing weight of evidence and would be appropriate to research capacity strengthening programmes both within and outside of a vectorborne disease context.
