[The German S3 guideline for depressive disorders in childhood and adolescence: new developments]

The German guideline for the treatment of depressive disorders in children and adolescents was first published in July 2013. Currently, this guideline is undergoing revision, in which the recommendations of the original version of the guideline are revisited and updated. This report aims to give an overview of the current status and the next steps for this revision.As part of the revision process, the key questions posited in the original version were expanded upon. In this, new questions were added regarding complementary therapies, that is, therapies meant to be administered in addition to the usual treatment, as well as regarding the transitionary period from adolescence into adulthood. For all key questions, new systematic literature searches were conducted in order to update the relevant evidence. For this, randomized controlled studies, systematic reviews, and non-controlled intervention studies were included and rated according to their relevance as well as possible risks of bias. Thus, all studies could be assigned a level of evidence that takes into account both the quality and the importance of the study to the guideline.This report will give a brief overview of the most important insights resulting from the new evidence base identified for the revision. While insights regarding psychotherapy are largely unchanged, there are changes in the evidence for certain antidepressants. In the field of complementary therapies, new evidence has been found for physical activity. In general, it is likely that most recommendations of the original guideline regarding first- and second-line treatments will be updated. The completion of the revision and the publishing of the revised guideline are expected to take until the end of 2023.
