Abstract
IntroductionTwo established subjective memory decline facets (SMD; complaints, concerns) are early indicators of memory decline and Alzheimer's disease. We report (1) a four‐facet SMD inventory (memory complaints, concerns, compensation, self‐efficacy) and (2) prediction of memory change and moderation by sex.MethodsThe longitudinal design featured 40 years (53 to 97) of non‐demented aging (n = 580) from the Victoria Longitudinal Study. Statistical analyses included confirmatory factor analyses and conditional latent growth modeling.ResultsThe four‐facet SMD Inventory was psychometrically confirmed. Longitudinal analyses revealed significant variability in level and change for SMD and memory. Prediction analyses showed complaints and concerns predicted lower level and steeper memory decline; however, follow‐up moderation analyses revealed selective predictions for females. Memory compensation predicted decline overall. Lower memory self‐efficacy predicted steeper decline selectively for males.DiscussionAlthough traditional and novel SMD facets predicted memory decline, differential sex moderation was observed. SMD research benefits from conceptual complementarity and precision prediction.
