Informed by both life course and biographical perspectives, our research design comprised two interviews incorporating recursive co-construction of the participant’s lifeline. We aimed to meet three objectives with this method: (1) to collect accurate retrospective data about the timing of lives; (2) to garner biographical data that allowed us to explore lives as wholes and (3) to elicit participant reflexivity on turning points associated with resilience. Our approach was distinctive in its explicit use of the lifeline both as a means to bring life stories into dialogue with life histories, and as a dynamic prompt to engage participants in the reflexive co-construction of turning points as fateful moments. We illustrate our approach through a case presentation and analysis of the reflexive lifelines co-constructed with two men who participated in our study. We also show how the reflexive lifeline interview generated opportunities for participant-led researcher reflexivity.
