How can parents avoid abusing their position of authority, without becoming too chummy? When should adolescent expressions of anxiety and depression warrant serious concern? What is a "problem adolescent"? What should be done in response to the dangers of drugs and of AIDS? First published by Editions Universitaires in 1988, The Many Facets of Adolescence has rapidly became a classic. It has been completely revised for the present edition, in particular the epidemiological data and the sections concerning adolescent depression and the relations between adolescents and their family. Alain Braconnier is a psychiatrist and director of the Centre Alfred Binet in Paris; he also teaches at the University of Paris-V. Daniel Marcelli is a psychiatrist specialising in childhood and adolescence.
