The purpose of this study is to evaluate change in 14 measures of social su
pport with data provided by a nationwide longitudinal study of older adults
. The findings reveal that fairly substantial change took place during the
three-year follow-up period. More important, the data indicate that change
is not uniform or systematic across the entire study sample. Instead, there
appears to be considerable individual-level change taking place. The impli
cations of these findings for the development of conceptual models as well
as support-based interventions are discussed.
