Further, the magnitudes of concurrent associations may differ across racial and ethnic groups that differ in Alzheimer\u2019s disease risk. The goals of this longitudinal study were to characterize prospective associations between positive psychosocial factors and cognitive decline and explicitly test for differential impact across race and ethnicity.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617720000648_as2\"><jats:title>Methods:<\/jats:title><jats:p>578 older adults (42% non-Hispanic Black, 31% non-Hispanic White, and 28% Hispanic) in the Washington Heights-Inwood Columbia Aging Project completed cognitive and psychosocial measures from the NIH Toolbox and standard neuropsychological tests over 2.4 years. Latent difference scores were used to model associations between positive psychosocial factors and cognitive decline controlling for baseline cognition, sociodemographics, depressive symptoms, physical health, and other positive psychosocial factors. Multiple-group modeling was used to test interactions between the positive psychosocial factors and race\/ethnicity.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617720000648_as3\"><jats:title>Results:<\/jats:title><jats:p>Higher NIH Toolbox Friendship scores predicted less episodic memory decline.
