Abstract: Background and Objectives: Despite the expected positive association between subjective functional difficulties (SFD) and subjective cognitive decline (SCD), their mediation by mentally unhealthy days (MUDs) is under-studied. Moreover, few SCD studies have examined affective reactivity to functional difficulties by age cohort. This study examined the mediation effect of MUDs on the association between SFD and SCD by age cohorts’ moderation among older adults. Methods: Using a cross-sectional design approach, we used the 2019 BRFSS dataset on 13,377 older adults aged 65 to ≥80 (44% males and 56% females). Results: The bias-corrected percentile bootstrap with 5000 s lings revealed that MUDs partially mediate the relationship between SFD and SCD (14.12% mediation effect), controlling depressive symptoms, education, income levels, and race. Age cohorts moderated the relationship between SFD and SCD and between SFD and SCD but not between MUDs and SCD. The predictive effects of the path from SFD to MUDs and from MUDs to SCD were stronger in the younger-old (65–69) than the middle-old (70–79) and oldest-old (≥80) age cohorts. Worse SCD was associated with being Asian, in female older adults, and in those with lower education and income levels. Conclusions: These findings extend the chronic stress theory predictions that accentuated emotional vulnerability to subjective functional difficulties may magnify SCD, particularly in the younger-old age group. By implication, preventive SCD interventions should seek to support younger-old adults in their activities of daily life for successful aging transitioning into older-age cohorts.

Abstract: (1) Background: This scoping review identifies subjective cognitive decline (SCD) indicators in ADLs and instrumental activities of daily living (IADLs) in older adults with depressive symptoms using the WHO International Classification of Functioning, Disability, and Health (ICF). (2) Methods: We searched Medline via Ebscohost, Pubmed, and PsycINFO for articles published on activities of daily living (ADL) indicators of SCD in older adults with depressive symptoms, published in English language journals from January 2011 to November 2021. Following the flow diagram, 2032 titles and abstracts were screened for relevance based on the Population, Concept, and Context inclusion and exclusion criteria. (3) Results: Eight articles provided evidence about the ADL indicators of SCD in older adults with depressive symptoms. The analysis yielded indicators based on low and high cognitively demanding tasks assessed on five different scales. Framed on the ICF categorization and coding system, the SCD-ADL indicators are personal care, mobility, and general tasks and demands SCD-IADL indicators are mobility, general tasks and demands, learning and applying knowledge, domestic life, communication, major life areas, and community, social, and civic life. (4) Conclusion: Highly cognitively demanding activities present more difficulties for in iduals with SCD, making IADLs a stronger predictor of SCD than ADLs.

Abstract: In older adults, subjective cognitive decline (SCD) may progress to an early stage of dementia. Yet, its association with subjective daily functional difficulties in aging is less well studied by experiences of mentally unhealthy days (MUDs). Employing a cross-sectional design approach, we analyzed the Behavioral Risk Factor Surveillance System dataset on 7429 older adults with SCD (aged 65 to >80, 45% males, 55% females) to explore SCD in instrumental daily activities of living (SCD-IADLs) and healthcare access mediation by MUDs and moderated mediation by age cohort, controlling gender and education. The bias-corrected percentile bootstrap with 5000 s lings revealed that MUDs partially mediate the relationship between SCD-IADLs and healthcare access, with a 28.2% mediating effect. Age cohort moderated the relationship between healthcare access and MUDs, MUDs and SCD-IADLs. Specifically, the predictive effects from healthcare access to MUDs and MUDs to SCD-IADLs were more profound in the 70-74 age cohort.

Abstract: To explore the application, diagnostic accuracy and predictors effecting the performance of the Rowland Universal Dementia Assessment Scale (RUDAS) in older populations living outside Australia. A literature review was conducted using a simplified approach of thematic analysis. A comprehensive computerized search of peer reviewed published papers (2004–2017) was conducted in Academic Search Complete (EBSCO), Medline with Full-text, Pubmed and Google Scholar using the following search terms: Rowland Universal Dementia Assessment Scale, sensitivity and specificity. Inclusion criteria were papers in which the RUDAS was used with older populations outside Australia and written in English. Database and manual searching identified a total of 289 papers and after reviewing the abstracts, titles and full-text papers, 12 papers were included in this review. Outside the target populations of culturally and linguistically erse communities in Australia, the RUDAS is applied internationally in Asia, Europe and Africa. The psychometric properties of the RUDAS were measured across these non-target population groups: sensitivity and specificity means, respectively were 80.9 (SD ±6.24 95% CI) and 76.1 (SD ±12.2 95% CI) RUDAS-MMSE mean correlation was 0.70 (SD ±0.14 95% CI) and mean AUC (area under curve) for RUDAS was 0.83 (SD ±0.08 95% CI). Findings from this literature review showed that the RUDAS has strong psychometric properties across many population groups who are culturally and linguistically erse in several countries. These findings provide support to undertake further research to evaluate the use of the RUDAS within culturally and linguistically erse communities in other countries.
