Drawing on the multinational qualitative study ‘Children’s Understandings of Well-being’ (CUWB), this unique edited collection offers practical insights into conducting fieldwork across diverse geographical, social and cultural contexts, using the same basic protocol. The book explores the practical, ethical and philosophical challenges the researchers faced, and the ways in which these issues were dealt with by the different research teams. Contributors provide rare insights into the diverse institutional requirements and professional practices highlighting the way research methods are embedded in contexts that are at one and the same time both local and global. With contributions from experts in child well-being research from Argentina, Australia, Canada, Chile, Germany, Romania, South Africa, Switzerland, Turkey, the UK and the US, the book provides valuable perspectives for researchers across a wide range of settings.
