Modifiers and Mechanisms of Loneliness Interventions

A specific aim of this research is to identify the role of emotion regulation in response to social threat in caregivers' response to a behavioral coaching intervention for loneliness. A second aim of the study is to determine the benefit of a digitized, social engagement prioritization tool for improving coaches' intervention fidelity and caregiver outcomes. This study is funded through the Pilot Award Program of the Rochester Roybal Center for Social Ties \& Aging Research, a UR Center funded by the National Institute on Aging by grant P30AG064103.
