Modifiers and Mechanisms of Loneliness Interventions

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.

The objective of this Stage III mechanistic study is to help identify additional modifiable targets and scalable approaches to support further development of highly effective, mechanistic-informed approaches to reducing loneliness and improving social connectedness in caregivers. This study is a Stage III, 19-month 2 (groups) x 2 (assessment timepoints) randomized clinical trial (RCT) aimed at identifying whether lonely caregivers' capacity, is associated with the degree to which loneliness is reduced in response to social engagement intervention (S-ENG). Further, the study will address whether a digitized, social engagement prioritization tool (C4C) used in the first session of S-ENG can improve intervention fidelity and
