Changes needed in the classification of anxiety disorders in childhood: Options for ICD-11

Considering the intensive preparation of the 11th revision of the International Classification of Diseases (ICD-11), we discussed the justification of the existing classification of emotional disorders with onset specific to childhood. This paper presents the citations from the ICD-10 (F93 block) and the authors' comments as a critical review of the justification of further existence of emotional disorders with onset specific to childhood as a separate block in ICD-11 classification. We concluded that the block F93 is insufficiently defined and should be completely changed or removed from the ICD-11 classification. Additionally, the specificities of the clinical picture of anxiety disorders in children should be adequately described within the future category of anxiety and phobic disorders by giving an explicit set of instructions for identifying clinical manifestations which vary by age.
