title: Stability and change in older adults' social contact and social support: the Cardiovascular Health Study.
abstract: OBJECTIVE
  The aim of this study was to examine the degree of individual change in structural indicators of social support (family network contact and close friend network contact) and functional indicators of social support (belonging, appraisal, and tangible support) during late life.
  
  
  METHODS
  Using a large population-based sample of older adults, hierarchical linear modeling was applied to examine the extent of change in social contact and support as well as sociodemographic characteristics (age, race, gender, and education) that might explain individual variability in contact and support at baseline and over time.
  
  
  RESULTS
  Consistent with predictions, small yet significant increases were observed in belonging support and tangible support. Contrary to predictions, no evidence was found for significant individual change in family network contact, close friend network contact, or appraisal support. Sociodemographic characteristics were more consistent predictors of variability in contact and support at baseline than variability over time.
  
  
  CONCLUSIONS
  The findings of this study add to a growing literature suggesting that late life is not typically characterized by a decline in important social resources.
