The study evaluates how self-rated health relates to cognitive health outcomes using a coordinated data analysis framework to strengthen robustness and replicability. Fourteen longitudinal datasets worldwide are analyzed with pre-registered tests for concurrent and longitudinal links to cognition and to odds of cognitive impairment or dementia, adjusting for demographic and health covariates.

We examined the extent to which self-rated health was associated with cognitive health outcomes, both cross-sectionally and longitudinally. Using the coordinated data analysis methodological framework to promote robustness an replicability in our findings, we identified 14 longitudinal datasets worldwide that met analytic inclusion criteria. Our pre-registered analyses tested whether self-rated health was associated with cognitive function both concurrently and at longitudinal follow up, as well as with odds of developing cognitive impairment or dementia over the course of the study, net of demographic and health covariates. Results indicated that, across nearly all datasets, higher self-rated health was associated with better cognitive function (both concurrently and longitudinally) and lower odds of developing dementia, over and above the effects of objective health (chronic conditions).Age moderated some of these effects, suggested that these associations may be strongest among older adults.","cbCaidvjgkrBFhtP","https://ap.wps.com/l/cbCaidvjgkrBFhtP","pdf",415649,"English","# Background\n## Self-rated health as a risk indicator\n# Methods\n## Coordinated data analysis framework\n## Dataset selection and pre-registered analyses\n# Results\n## Associations with cognitive function\n## Odds of cognitive impairment or dementia\n## Age moderation of effects\n# Conclusion\n## Robust, replicable evidence across datasets","[{\"question\":\"How does the study define and use self-rated health?\",\"answer\":\"Self-rated health is treated as a non-invasive, low-cost way to identify later-life individuals at risk of poor health, and it is examined as a predictor of cognitive outcomes.\"},{\"question\":\"What analytical approach supports robustness and replicability?\",\"answer\":\"The study applies a coordinated data analysis methodological framework and uses pre-registered analyses across multiple datasets.\"},{\"question\":\"What were the main findings about self-rated health and cognitive outcomes?\",\"answer\":\"Across nearly all datasets, higher self-rated health was linked to better cognitive function concurrently and longitudinally, and to lower odds of developing dementia beyond objective health effects.\"}]","MULTI-STUDY COORDINATED ANALYSIS TO PROMOTE REPLICABILITY: EXAMPLE USING SELF-RATED HEALTH - Issue 2 - Abstract citation ID igaf122.1459 | PDF",1790641480]
