This volume presents the current state of knowledge on the topic of behavioural disturbances among young people, in the form of a handbook. It is concerned with children and young adults whose behaviour diverges from society=s expectations in undesirable ways - i.e., young people who show symptoms of neglect, psychosocial disturbances, delinquent behaviour and/or severe anxiety, depression and suicidal tendencies. The authors present effective educational approaches and measures in a clearly arranged way. They describe and evaluate diagnostic procedures, list tested and effective interventional methods and analyse the work and functioning of the relevant institutions. The book thus provides a comprehensive introduction for students and also up-to-date guidance for specialists.
