Life Satisfaction Prevents Decline in Working Memory, Spatial Cognition, and Processing Speed: Latent Change Score Analyses Across 23 Years

BackgroundWithin-person growth in life satisfaction (LS) can protect against declines in cognitive functioning, and, conversely, over time. However, most studies have been cross-sectional, thereby precluding causal inferences. Thus, we used bivariate dual latent change score modeling to test within-...

Description
Summary:BackgroundWithin-person growth in life satisfaction (LS) can protect against declines in cognitive functioning, and, conversely, over time. However, most studies have been cross-sectional, thereby precluding causal inferences. Thus, we used bivariate dual latent change score modeling to test within-person change-to-future change relations between LS and cognition.MethodCommunity adults completed in-person tests of verbal working memory (WM), processing speed, spatial cognition, and an LS self-report. Five waves of assessment occurred across 23 years.ResultsReduction in LS predicted future decreases in spatial cognition, processing speed, and verbal WM (|d| = 0.150–0.354). Additionally, depletion in processing speed and verbal WM predicted a future decrease in LS (d = 0.142–0.269). However, change in spatial cognition did not predict change in LS (|d| = 0.085).DiscussionLS and verbal WM and processing speed predicted one another across long durations. Evidence-based therapies can be augmented to target LS and cognition.
