Accessing Behavior for Clinical Data and Joint Usage (ABCD-J)

A platform for digital biomarkers and mhealth in Northrhine Westfalia

The DataLad logo, the Forschungszentrum Jülich logo with a smartphone in it and four data set icons labeled “A, B, C and D” overlay an outline of Germany. There are seven hexagons representing components of the ABCD-J project, including 1) a doctor, 2) laboratory measurements of /ha/, /pa/, /k/ and /tuin/, 3) body measurements with sensors, 4) facial expression measurements, 5) connection nodes labeled “1, 2, 3, 4, 5, 6” on a tablet, 6) three smartphone screenshots of the JTrack app, and 7) an ellipse.

Clinical data is usually only collected in contact with doctors. Wearables from patients provide physicians with valuable data that complements the casual observations of individual patients in the clinical setting and from which digital biomarkers for health and disease can be derived. The ABCD-J platform provides an integrated collection and analysis environment for digital biomarkers & mobile health in North Rhine-Westphalia - by clinical researchers for clinical researchers.
