Tony Osgood speaks from 30 years of experience, which is evident in the richness of insights he shares throughout this book... Highlights include Osgood's novel and refreshingly honest way of confronting the challenges for professionals and families working together... Humour and seriousness are aptly balanced. Another chapter is dedicated to the importance of communication, namely the role of mediators in thinking of legitimate ways to hear the person's message better and nurture the 'ebb and flow of interactions'... Not surprisingly, there is plenty of strong science here, and Osgood takes the reader through PBS essentials such as person centred functional behaviour assessment, working with multiple behaviours and behavioural functions, and use of data recording... This is the kind of book that will be of high interest to experienced practitioners...Then again, it is also a book that students and early career practitioners will benefit from in that it puts out key messages and sows the seeds for the right thinking from the beginning. The book is a highly refreshing read.
