Abstract

Although intolerance of uncertainty (IU) is associated with negative outcomes, studies focusing on older adults are still emerging. Specifically, the relationship between IU and psychological health in this population remains unclear. Moreover, no review has focused on understanding the unique contributions of IU and aging to anxiety and mental health in older adults. This scoping review and meta-analysis addressed this gap and provided a comprehensive understanding of the relationship between IU, aging, and mental health. Among 45 studies reviewed, 37 were included in the meta-analysis using mixed effect analysis to examine the relationship between IU and age across adulthood. The remaining eight studies, along with seven selected from the meta-analysis, were included in the scoping review to evaluate the relationship between IU, anxiety, and mental health. Among these, 12 studies focused on late adulthood, two on overall adulthood, and one included both late and overall adulthood. Results of the meta-analysis revealed an overall significant age difference in IU throughout adulthood. Moreover, results of the scoping review indicated a direct correlation between IU and anxiety, and other psychological issues in elderly. These findings provide insights for future research and interventions aimed at reducing IU and improving mental health among older adults.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
