A systematic review of psychometric properties of questionnaires assessing activities of daily living among older adults with neurocognitive disorders
Bibliographic record
Abstract
INTRODUCTION: Mild cognitive impairment (MCI) and Alzheimer's disease (AD) lead to decline in performance in activities of daily living (ADLs). Multiple questionnaires assess this construct among older adults. The objective of this study was to review existing literature studying psychometric properties of questionnaires assessing performance in ADLs of older adults living with MCI and AD specifically. METHODS: A systematic review was conducted across Medline, CINAHL and PsychINFO using a combination of keywords related to ADLs, psychometrics, MCI and AD. Studies were included if they met the following criteria: assessments of performance of ADLs for older adults living with AD or MCI, reporting a minimum of one measurement property (e.g. internal consistency), primary research articles, published before June 2023 in English or French. Data extraction and analysis were conducted by two researchers. The methodological quality of psychometric properties was assessed using the COSMIN checklist. CONSUMER AND COMMUNITY INVOLVEMENT: No consumer or community involvement occurred. RESULTS: A total of 2539 articles were screened and filtered down to 50 articles including 24 questionnaires respecting inclusion criteria. Of these questionnaires, the three most validated were the Amsterdam Instrumental activities of daily living, the disability assessment for dementia (DAD), and the Bayer ADL scale. Overall, for these three questionnaires, internal consistency, reliability and structural validity were the most studied psychometric properties while criterion validity and hypothesis testing were the least. CONCLUSION: This study reveals the Amsterdam IADLs as the most validated questionnaire across psychometric properties and the DAD as the most validated across languages. Considering the increasing prevalence of older adults with MCI or AD, questionnaires established on strong measurement properties are valuable tools to evaluate decline in ADL performance and plan suitable interventions. This review provides evidence for clinicians and researchers for the selection of questionnaires to evaluate this population. PLAIN LANGUAGE SUMMARY: Cognitive impairment affects memory and thinking. It makes tasks like dressing, bathing and eating harder. Health-care workers use questionnaires to find out where someone struggles. This helps them plan better care. We reviewed questionnaires for older adults with memory and thinking problems. We found good ones that give important information. Using these questionnaires helps health-care workers support people with daily tasks. This study suggests testing the questionnaires more to improve them.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
