The book discusses challenging forms of behaviour in all of the major fields of social work & from welfare services for children and young adults, to help for ex-offenders, to social work in the fields of psychiatry and disabled care. For ease of understanding, each chapter starts with an outline case taken from everyday work. Building on this, well-founded explanations are given for each of the behaviour patterns, in order to present concrete approaches for ways of dealing with them. Each chapter closes with an interview, with specialists in social work reporting directly from their practical work and thus making their extensive knowledge available to readers.
