Validity and reliability of the Brazilian Portuguese version of the Australian National University - Alzheimer's Disease Risk Index (ANU-ADRI)

Validity and reliability of the Turkish version of the Australian National University-Alzheimer's Disease Risk Index (ANU-ADRI)

INTRODUCTION

There is still a requirement for concise, practical scales that can be readily incorporated into everyday schedules and predict the likelihood of dementia onset in individuals without dementia. This study aimed to assess the reliability of the ANU-ADRI (Australian National University Alzheimer's Disease Risk Index)-Short Form in Turkish geriatric patients.

METHODS

This methodological study involved 339 elderly patients attending the geriatric outpatient clinic for various reasons. The known-group validity and divergent validity were assessed. The ANU-ADRI was administered during the baseline test and again within one week for retest purposes. Alongside the ANU-ADRI, all participants underwent a comprehensive geriatric assessment, including Activities of Daily Living (ADL), mobility assessment (Performance-Oriented Mobility Assessment (POMA) and Timed Up and Go Test), nutritional assessment (Mini Nutritional Assessment (MNA)), and global cognition evaluation (Mini-Mental State Examination (MMSE)).

RESULTS

The scale demonstrated satisfactory linguistic validity. A correlation was observed between the mean scores of the ANU-ADRI test and retest (r = 0.997, p < 0.001). Additionally, there existed a moderate negative linear association between the ANU-ADRI and MMSE scores (r = -0.310, p < 0.001), POMA (r = -0.406, p < 0.001), Basic ADL (r = -0.359, p < 0.001), and Instrumental ADL (r = -0.294, p < 0.001). Moreover, a moderate positive linear association was found between the ANU-ADRI and the Timed Up and Go Test duration (r = 0.538, p < 0.001).

CONCLUSION

The ANU-ADRI-Short Form was proved as a valuable tool for clinical practice, facilitating the assessment of Alzheimer's disease risk within the Turkish geriatric population.

Cross-cultural adaptation and validation of the Australian National University Alzheimer Disease Risk Index (ANU-ADRI) for Chinese community-dwelling residents: A cross-sectional Study

OBJECTIVE

To cross-culturally adapt the Australian National University Alzheimer Disease Risk Index (ANU-ADRI) and verify the reliability and validity of its cognitive activity domain.

METHODS

According to Beaton's guidelines, the ANU-ADRI was were translated into Chinese. The psychometric properties of ANU-ADRI its cognitive activity was conducted among community-dwelling residents (n = 442) in Changchun, Harbin and Hegang from December 2021 to July 2023.

RESULTS

The Chinese version of the ANU-ADRI had good content validity and face validity. Exploratory factor analysis of cognitive activity revealed a 3-factor structure, with a cumulative variance contribution rate of 64.124 %. Confirmatory factor analysis revealed a good model fit (x2/df = 1.664, RMSEA = 0.055, RMR = 0.090, GFI = 0.942, CFI = 0.919, IFI = 0.921, TLI = 0.902, and NFI = 0.824). The internal consistency (Cronbach's α = 0.807) and test-retest reliability (ICC = 0.787) were considered satisfactory.

CONCLUSION

The ANU-ADRI showed acceptable reliability and validity for assessing risk factors for Alzheimer's disease among middle-aged and elderly community-dwelling residents.

Dementia Risk Scores and Their Role in the Implementation of Risk Reduction Guidelines

Dementia prevention is a global health priority. In 2019, the World Health Organisation published its first evidence-based guidelines on dementia risk reduction. We are now at the stage where we need effective tools and resources to assess dementia risk and implement these guidelines into policy and practice. In this paper we review dementia risk scores as a means to facilitate this process. Specifically, we (a) discuss the rationale for dementia risk assessment, (b) outline some conceptual and methodological issues to consider when reviewing risk scores, (c) evaluate some dementia risk scores that are currently in use, and (d) provide some comments about future directions. A dementia risk score is a weighted composite of risk factors that reflects the likelihood of an individual developing dementia. In general, dementia risks scores have a wide range of implementations and benefits including providing early identification of individuals at high risk, improving risk perception for patients and physicians, and helping health professionals recommend targeted interventions to improve lifestyle habits to decrease dementia risk. A number of risk scores for dementia have been published, and some are widely used in research and clinical trials e.g., CAIDE, ANU-ADRI, and LIBRA. However, there are some methodological concerns and limitations associated with the use of these risk scores and more research is needed to increase their effectiveness and applicability. Overall, we conclude that, while further refinement of risk scores is underway, there is adequate evidence to use these assessments to implement guidelines on dementia risk reduction.

Awareness raising workshop for nursing students on the elderly with Alzheimer's disease: contributions to education

OBJECTIVE

To describe the contribution of an awareness-raising workshop for nursing students on Alzheimer's disease in the context of the elderly/family.

METHODS

Strategic action-research developed with 15 university students from the sixth to the eighth semester of Nursing at a university institution in the Rio Grande do Sul. The data collected through semi-structured interviews, before and after an awareness-raising workshop on Alzheimer's disease in elderly/family, were subjected to thematic content analysis.

RESULTS

Six categories were identified that concern (Mis) perception of Alzheimer's disease in the context of elderly/ family, from the characterization; risk factors; diagnosis; treatment of Alzheimer's disease; from care to family members/caregivers; and care strategies for the elderly with Alzheimer's disease.

CONCLUSION

The awareness-raising workshop enabled the students to broaden and deepen the knowledge on the theme of Alzheimer's disease in the elderly.
