This book provides a detailed and comprehensive guide to working with risk. It begins by looking at notions of need, vulnerability and protection and looks at the theoretical concepts of each before applying them to practice. By using this combination of theory and practice the authors are able to integrate policy for a wide range of services users, from older people to children, families and younger adults. Case studies accompany and illustrate each method and the reader is invited to engage in a number of exercises and activities to consolidate learning.
