This book brings together the thinking of an international group of clinicians, researchers, and professionals from different disciplines and is based primarily on a selection of papers presented at a conference on the same topic held at the Tavistock Centre, London, in November 1996, but with additional original contributions. It presents a dialogue amongst the various perspectives that can be taken about atypical gender identity development and their relevance to mental health in children and adolescents. The book is aimed at a multidisciplinary professional readership and interested lay people.
