The Impact of Custodial Grandparenting on Cognitive Performance in a Longitudinal Sample of Grandparents Raising Grandchildren

Abstract

There are currently 2.7 million grandparents raising grandchildren in the United States. As grandparent caregiving has become more prevalent, concerns have surfaced regarding the effect of additional caregiving responsibilities placed on an aging population. The following study uses an existing dataset of individuals who graduated from Wisconsin high schools in 1957. The present study examined the impact of grandparenting on measures of cognition, both cross-sectionally and longitudinally. Findings from the cross-sectional analysis show that custodial grandparents outperformed their noncustodial grandparent counterparts on the cognitive tests of word recall, category fluency, letter fluency, and cognitive similarities. Findings from the longitudinal analysis show that though custodial grandparents had initially performed worse on the digit ordering task, their scores declined at a much slower rate than non-custodial grandparents. By using a cross-sectional and longitudinal research design, this study provides a unique opportunity to examine the impact of grandparenting on cognitive performance.
