Dr. Hane Aung discusses how digital technologies can help assess and monitor mental health. Traditional paper questionnaires are not objective or continuous. Sensors in mobile devices can objectively track behaviors correlated with conditions like depression and schizophrenia. Studies have linked sensor data on social interactions, activity levels, and sleep to symptoms. Ecological momentary assessments on mobile apps also correlate sensor data to self-reported symptoms. Recommendation systems using this data aim to promote well-being for issues like chronic pain. Future work includes using these methods for Alzheimer's and assessing driving ability in pre-Alzheimer's patients.
