Changes in, and predictors of, interpersonal dynamics over 18 years in the Australian Longitudinal Study of Ageing

Despite growing interest in how aging-related changes in the social context of older adulthood are shaped, very few longitudinal studies have examined the nature, or predictors, of changes across different social domains (social activity engagement, satisfaction with networks, negative exchanges) . We used 18-year data from up to 6 occasions for 1477 primary participants (65 -103 yrs) in the Australian Longitudinal Study of Ageing. Multilevel Growth Models indicated no change in satisfaction with friends or negative social exchanges, but declines for family satisfaction and social engagement. Declines in family satisfaction were more pronounced among older and less depressed individuals, while reductions in social engagement were more likely among widows and those with more chronic conditions. Baseline widowhood also predicted satisfaction with family and engagement. Morbidity and depressive symptoms varied in their associations with social domains. Discussion will focus on how to optimise social functioning in late life.
