Abstract: Inactivity, lack of sleep, and poor nutrition predispose individuals to health risks. Momentary Patient-Reported Outcomes (PROs) assess short-term physical behaviors and psychological states for a given recall period (ranging from weeks to seconds) but suffer from reporting biases. Conversely, wearables are an increasingly accurate source of long-term behavioral Technology-Reported Outcomes (TechROs). However, the extent to which short-term PROs and TechROs provide convergent information is unknown. We propose the coQoL co-calibration method for short-term QoL and long-term TechRO and report its feasibility, reliability, and human factors influencing these. We present the first results for the coQoL method based on a dataset collected with 42 seniors for three years. Our results can inform designs of longitudinal assessments and, whenever appropriate, personalized interventions.
