This book takes as its starting point the particular considerations and sensitivities of being a researcher faced with a subject group at the margins of society, and explores the ethical, practical, and methodological implications of working with such groups. Author Pranee Liamputtong explores qualitative methods using examples, drawn from around the world, and from the wide variety of contexts that might count as 'researching the vulnerable'. Numerous salient points for the conduct of research within vulnerable groups of people, including ethical and moral issues, are considered, and discussed in the context of sensitive and innovative research methods. This is an ideal reference for any graduate student taking a course in research methods, and PhD research training courses across the Social Sciences.
