Since 2009 trends in research and practice have been described for externalising disorders (ADHD and conduct disorders) in the German-speaking countries. In particular, publications of children and adolescent psychiatry and clinical child psychology have been examined and scientific contributions from the 32nd Congress of the German Society for Child and Adolescent Psychiatry have been included. In the German-speaking countries studies regarding conduct disorders (including bullying and psychopathy) have noticeably increased in complexity and differentiation and caught up with the extensive discussion about ADHD.
