Loneliness trajectories and correlates of social connections among older adult married couples.

How loneliness manifests in older adult married couples is necessary to consider. Marriage partners may become more or less lonely based on shared circumstances with one another (i.e., the shared environment hypothesis). Moreover, individuals may pair off with a marriage partner who shares similar levels of loneliness (i.e., the homophily hypothesis; Cacioppo, Fowler, & Christakis, 2009), which can potentially lead to higher or lower levels of loneliness. Therefore, examining couples dyadically is beneficial in order to understand how loneliness operates over time. Three waves of the Health and Retirement Study were used and participants included 1,389 older adult couples. The current study uses growth-mixture modeling to examine older adult couples’ joint loneliness trajectories. Multinomial logistic regressions were also used to examine social and demographic correlates of these trajectories. Three classes emerged, including classes characterized by high loneliness (N = 69), low lon
