“…There is growing evidence that performance-based evaluations might have more advantages over other assessment approaches [9,32,33]. However, only few of them are developed to assess MCI or mild dementia [55,93], and they are mostly too time- and cost-consuming to be administered [9,31].…”

“…However, our i-ADL-DI and i-ADL-CDI show similar accurate validity to discriminate between HC, MCI, and AD. So, although this study developed a report-based measure—which may not be as accurate in detecting functional difficulties in persons with mild cognitive decline—the results of this study indicate that the ICF-based evaluation of b- and i-ADL might compete with the recently developed performance-based tools as the standard for classifying functional status and decline [32,33,55,94]. Ongoing research will clarify this and is already assessing the convergent validity between the ICF-based evaluation of b- and i-ADL and a performance-based measure.…”

Early diagnosis of mild cognitive impairment and mild dementia through basic and instrumental activities of daily living: Development of a new evaluation tool

BackgroundAssessment of activities of daily living (ADL) is paramount to determine impairment in everyday functioning and to ensure accurate early diagnosis of neurocognitive disorders. Unfortunately, most common ADL tools are limited in their use in a diagnostic process. This study developed a new evaluation by adopting the items of the Katz Index (basic [b-] ADL) and Lawton Scale (instrumental [i-] ADL), defining them with the terminology of the International Classification of Human Functioning, Disability and Health (ICF), adding the scoring system of the ICF, and adding the possibility to identify underlying causes of limitations in ADL.Methods and findingsThe construct validity, interrater reliability, and discriminative validity of this new evaluation were determined. From 2015 until 2016, older persons (65–93 y) with normal cognitive ageing (healthy comparison [HC]) (n = 79), mild cognitive impairment (MCI) (n = 73), and Alzheimer disease (AD) (n = 71) underwent a diagnostic procedure for neurocognitive disorders at the geriatric day hospital of the Universitair Ziekenhuis Brussel (Brussels, Belgium). Additionally, the ICF-based evaluation for b- and i-ADL was carried out. A global disability index (DI), a cognitive DI (CDI), and a physical DI (PDI) were calculated. The i-ADL-CDI showed high accuracy and higher discriminative power than the Lawton Scale in differentiating HC and MCI (area under the curve [AUC] = 0.895, 95% CI .840–.950, p = .002), MCI and AD (AUC = 0.805, 95% CI .805–.734, p = .010), and HC and AD (AUC = 0.990, 95% CI .978–1.000, p < .001). The b-ADL-DI showed significantly better discriminative accuracy than the Katz Index in differentiating HC and AD (AUC = 0.828, 95% CI .759–.897, p = .039). This study was conducted in a clinically relevant sample. However, heterogeneity between HC, MCI, and AD and the use of different methods of reporting ADL might limit this study.ConclusionsThis evaluation of b- and i-ADL can contribute to the diagnostic differentiation between cognitively healthy ageing and neurocognitive disorders in older age. This evaluation provides more clarity and nuance in assessing everyday functioning by using an ICF-based terminology and scoring system. Also, the possibility to take underlying causes of limitations into account seems to be valuable since it is crucial to determine the extent to which cognitive decline is responsible for functional impairment in diagnosing neurocognitive disorders. Though further prospective validation is still required, the i-ADL-CDI might be useful in clinical practice since it identifies impairment in i-ADL exclusively because of cognitive limitations.

“…They can be classified as basic activities of daily living (BADLs), which refer essentially to personal care, or instrumental activities of daily living (IADLs), which involve a greater interaction with the social environment and higher cognitive demands. IADLs also are known as complex (7) health management and maintenance, such as maintaining a healthy routine, taking physical exercise, having adequate nutrition and annual health checkups, avoiding health risk behaviors and handling medication if necessary; (8) home establishment and management: for example, searching for a home and taking care of it, repairing clothes and personal belongings or cleaning the home; (9) meal preparation and cleanup: it includes planning a balanced and nutritious diet, cooking and cleaning after meals; (10) religious and spiritual activities and expression; (11) safety and emergency maintenance: knowing and developing processes to prevent accidents and responding to unexpected hazards or emergencies; and (12) shopping: it incudes making a shopping list, selecting the goods and payment method and purchasing the goods.…”

“…There are other functional cognition assessments including the Assessment of Motor and Process Skills (AMPS) (Robinson & Fisher, 1996), Large Allen's Cognitive Level Screen (Allen et al, 2007) and the Kitchen Task Assessment (KTA) (Baum & Edwards, 1993). However, no specific assessment tool was recommended in a recent systematic review of 21 identified instruments (Wesson, Clemson, Brodaty & Reppermund, 2016). They reported that evidence of psychometric properties is lacking and there is a need for further evaluation of instruments for use with older people with suspected cognitive impairment.…”

Background/aim Limited research has been available to support the use of the Kettle Test in a subacute rehabilitation setting with patients diagnosed with a variety of medical conditions. The Kettle Test is an occupation based performance measure designed to detect cognitive processes and function. The aim of this research was to measure the correlation between three cognitive tests, the Mini‐Mental State Examination (MMSE), Cognitive Functional Independence Measure (Cognitive FIM) and the Kettle Test. Secondly, to assess the efficacy of these tests in predicting functional outcomes via the motor subscale of the Functional Independence Measure (mFIM). Methods A prospective single‐centre cohort study in a subacute rehabilitation setting of 97 patients. Results Correlation coefficients between the tests were statistically significant and moderately strong, with values ranging from 0.593 to −0.589. Significant positive correlations were seen between admission MMSE, Cognitive FIM and the mFIM and significant negative correlations between Kettle Test scores and the mFIM. The Kettle Test score had a stronger relationship with mFIM (r = −0.40; P < 0.01) compared to the Cognitive FIM (r = 0.33; P < 0.01) and MMSE (r = 0.26; P < 0.05). The Kettle Test variance is significantly associated with the MMSE and Cognitive FIM at admission and discharge measures. Modelling identified that age and gender significantly contribute to this relationship. When adjusted for age and gender the MMSE and Cognitive FIM both explained the 47% of the variance at discharge. Conclusion There were statistically significant inter‐test correlations between the MMSE, Cognitive FIM and Kettle Test. The Kettle Test had the strongest relationship to patient functional outcomes.
