N2 - Activity limitations can diminish life satisfaction. This study explored the role of optimism on the relationship between changes in activities of daily living and instrumental activities of daily living (ADL/IADL) limitations and life satisfaction over time among middle-aged and older adults. Growth curve modeling accounting for intra- and inter-individual changes in life satisfaction was applied to the 2008-2018 waves of the Health and Retirement Study Leave Behind Survey subsample (
n = 39,122 person-years). After controlling for sociodemographic factors, physical functioning decline adversely affected life satisfaction (
β
ADL = -0.12,
β
IADL = -0.13,
p < 0.001), but the negative consequences reduced slightly through optimism (
β
ADL = -0.11,
β
IADL = -0.12,
β
optimism = 0.47,
p < 0.001). Increasing optimism could reduce the negative consequences of ADL/IADL limitations on life satisfaction among middle-aged to older adults.
