As the COVID-19 pandemic hit researchers' plans, discussion swiftly turned to adapting research methods for a locked-down world. The 'big three' methods - questionnaires, interviews and focus groups - can only be used in a few of the same ways as before the pandemic. Researchers around the world have responded in diverse, thoughtful and creative ways - from adapting their data collection methods, to fostering researcher resilience and rethinking researcher-researched relationships. This book, part of a series of three Rapid Responses, showcases new methods and emerging approaches. Focusing on Response and Reassessment, it has three parts: the first looks at the turn to digital methods; the second reviews methods in hand and the final part reassesses different needs and capabilities. The other two books focus on Care and Resilience, and Creativity and Ethics. Together they help academic, applied and practitioner-researchers worldwide adapt to the new challenges COVID-19 brings.
