Hello, @robertoguarnieri ! If you can’t find this scale in Athena but there is a great need in it for your mapping, you can create 2bil+ concept for it in your custom vocabulary. It is temporary solution. You can ask @Dymshyts for help and go to Psychiatry WG (projects:workgroups:psychiatry [Observational Health Data Sciences and Informatics]) and visit this topic (How to store Psychiatric Scale into OMOP data base?). This is psychiatric topic, but related to neurology)
