Interviewing adolescents through time: balancing continuity and flexibility in a qualitative longitudinal study

Qualitative longitudinal research (QLR) has great potential for elucidating processes and change over time. Despite the growing interest in QLR, methodological and practical challenges require further reflection. In this contribution, we reflect on two major issues in interviewing adolescents in QLR: panel maintenance and changes in the research set-up, including interviewing technique, content and interviewer (dis)continuity. Based on experiences from a panel study on understanding how young people’s opportunities in life are shaped during a transitional stage (‘Pathways to the Future’), we present methodological and pragmatic decisions, rationales and lessons learnt to inform future qualitative longitudinal studies. We show how change is omnipresent in QLR practice, and how it demands researchers’ openness and flexibility as well as finding a balance between continuity and adaption. The process can be challenging, but it also offers opportunities.
