Trust, nuance, and care: Advantages and challenges of repeat qualitative interviews

Most methodological discussions about the pros and cons of repeat interviews fall within qualitative longitudinal literature and are premised on project designs with relatively long intervals between encounters. Less attention has been paid to the practice and ethics of repeat interviewing as a stand-alone method, that does not follow participants long-term, but instead conducts several interviews over a short period of time. This article is based on interviews and research logs from a project in which over 350 incarcerated persons in Latin America were interviewed. We evaluate the advantages and shortcomings of repeat interviewing, in this case, three sessions with each participant with up to a week in between sessions. We find that repeat interviewing increases trust and rapport, contributes to nuanced data, generates reflexivity, and ensures more ethical research by making it easier for researchers to care for participants. Yet the method also has the disadvantages of demanding a significant investment of resources, the risk of losing participants, and on occasion, the emotional challenge of breaking strong bonds when researchers and participants part ways. We argue that the advantages of repeat interviews exceed the shortcomings, but ethical concerns added to the cost in time, energy, and money might at times proscribe the method.
