Subjective cognitive decline (SCD) may precede objective cognitive impairment. This study examined prevalence, type of SCD, and associations with neuropsychological measures among diverse older adults. The sample included older adults from three ethnoracial groups enrolled in the U.S. Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk (POINTER) trial. Everyday Cognition (ECog) measured SCD, and neuropsychological function was assessed using global memory, executive function, and processing speed composites. The study found that Hispanic/Latinx participants were more likely to report SCD than non-Hispanic White (NHW) or Black participants, particularly executive function concerns. SCD ratings were associated with many of the neuropsychological domains in NHW participants and with processing speed among Black participants; no association was observed in Hispanic/Latinx participants.
