Changes in adult children's participation in parent care.

Care-giving research has focused on primary care-givers and relied on cross-sectional data. This approach neglects the dynamic and systemic character of care-giver networks. Our analyses address changes in care-givers and care networks over a two-year period using pooled data from the US Health and Retirement Study, 1992–2000. Based on a matrix of specific adult-child care-givers across two consecutive time-points, we assess changes in any adult-child care-giver and examine the predictors of change. A change in care-giver occurred in about two-fifths of care-giving networks. Ability to provide care based on geographical proximity, availability of alternative care-givers, and gender play primary roles in the stability of care networks. Results underline the need to shift care-giving research toward a dynamic and systemic perspective. [ABSTRACT FROM PUBLISHER]
