Abstract
Digital markers of mental health problems have gained attention in research as a result of the growing accessibility and data-generating capabilities of portable digital devices. Through sensors (e.g., geolocating system) and human-device interactions (e.g., keystrokes), smartphones and wearable devices can be used to generate digital indices that aim to capture a person’s mental health states and mental health determinants across biological, psychological, and environmental dimensions. Important advantages of digital (bio)markers include the potential to measure mental health on a day-to-day basis and in the person’s usual environment (rather than in the clinician’s office) and with minimal intervention required from the user. Digital markers can be combined with survey data and other variables as part of tailored predictive models with the aim of helping patients and clinicians better detect, monitor, and manage mental health conditions. In this chapter, we define digital markers in psychiatry and examine their types and applications using examples drawn from the scientific literature. We also consider some of the limitations of existing research, ethical problems, and other barriers to the implementation of digital phenotyping in clinical practice.
