Abstract
Sociological research has documented myriad associations between individuals' overall social connectedness and health, but rarely considers the shorter-term dynamics of social life that may underlie these associations. We examine how being with others ("social accompaniment") is associated with momentary experiences of symptoms, drawing smartphone-based ecological momentary assessments (N=12,720) collected from 342 older adults from the Chicago Health and Activity in Real Time study. We find that patterns of social accompaniment are distinct from global measures of social integration such as network size. Older adults who are in the company of a friend or neighbor are significantly less likely to experience momentary fatigue and stress, even after accounting for overall measures of social integration. These results suggest that social accompaniment has unique implications for short-term health outcomes. New theoretical perspectives and empirical analyses are needed to better understand the dynamic nature of everyday social accompaniment and its longer-term implications for well-being.
