Many people find themselves without the experience or skills to deal with individuals with behaviour they do not like or find threatening. This much-needed new text provides insights and access to a range of therapeutic interventions. The book is divided into three sections. The first provides theoretical background, addresses legal and ethical issues, and raises questions about the language we use to describe behaviour we find difficult to understand. This is followed by the main part of the book and descriptions of seven different approaches and interventions. The third section of the book discusses the problematic nature of evidence for choosing particular interventions and therapies.
