"This book by Roger Hughes and Barrie Margetts is a valuable tool for those working in PHN as it not only
summarises the steps that are necessary for successful intervention but it also provides a number of practical examples that will help understand each step of an intervention. It will also be of benefit to students as a key textbook, providing them with basic skills/knowledge in the area of PHN practice." (Journal Nutrition Bulletin, 1 September 2011)
