What is the role of Digital Phenotyping regarding Digital Biomarkers?
Answer
It is the method generating specific, quantifiable digital biomarkers.
Digital phenotyping and digital biomarkers are closely related but distinct concepts. Digital phenotyping is defined as the broader, objective methodology involving the continuous, high-frequency gathering of behavioral and engagement data derived from personal digital devices. This process serves as the engine or method for generating the specific, measurable outputs. Once this high-frequency behavioral data is processed through analysis, the derived, quantifiable metrics—such as the average time between smartphone unlocks per hour—are then formalized as the digital biomarkers used for health assessment.
