Abstract
BACKGROUND Literacy is an important factor that predicts cognitive performance. Existing cognitive screening tools are validated only in educated populations and are not appropriate for older adults with little or no education leading to poor performance on these tests and eventually leading to misdiagnosis. This challenge for clinicians necessitates a screening tool suitable for illiterate or low-literate older individuals. OBJECTIVES The objective was to adapt and validate Addenbrooke's Cognitive Examination-III (ACE-III) for screening general cognitive functions in illiterate and low-literate older populations in the Indian context in three languages. METHOD The Indian illiterate ACE-III was systematically adapted by modifying the original items of the Indian literate ACE-III to assess the cognitive functions of illiterates and low-literates with the consensus of an expert panel of professionals working in the area of dementia and related disorders. A total of 180 illiterate or low-literate participants (84 healthy-controls, 50 with dementia, and 46 with mild cognitive impairment [MCI]) were recruited from three different centers speaking Bengali, Hindi, and Kannada to validate the adapted version. RESULTS The optimal cut-off score for illiterate ACE-III to distinguish controls from dementia in all 3 languages was 75. The optimal cut-off scores in distinguishing between controls and MCI ranged from 79 to 82, with a sensitivity ranging from 93% to 99% and a specificity ranging from 72% to 99%. CONCLUSION The test is found to have good psychometric properties and is a reliable cognitive screening tool for identifying dementia and MCI in older adults with low educational backgrounds in the Indian context.

Abstract
Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive screening that evaluates older people with low educational levels. In Chile, there are no normative data to assess this population. Objective To obtain normative data on RUDAS in older Chilean people with up to 12 years of schooling, and to determine whether age and schooling years influence a person's performance on RUDAS and on the items that constitute it. Methods A group of cognitively healthy people 60 years old or over, with up to 12 schooling years was evaluated (n=135). Multiple regression models were applied to obtain normative data on RUDAS, according to age and schooling years, and to measure the effects of schooling on different items. Results Regression analysis showed that none of the items had schooling as a significant predictor, except for the visuoconstruction item. The variables age and schooling explained 12.6% (R^2=0.126) of the RUDAS total score variance. The item visuoconstruction was the most associated with the educational level (OR=1,147). Conclusion This study showed that RUDAS is a recommended instrument for evaluating older people with low educational levels. However, more studies are needed to prove the validity of the RUDAS on Chilean older people.

Abstract
The South-East Asia region has one of the fastest-growing aging populations, for which standardized dementia screening measures will be essential for geriatric care. The Rowland Universal Dementia Assessment Scale (RUDAS) is adopted for use in the Indonesian setting but lacks evidence of its cross-cultural transportability. This study aimed to examine the reliability and validity of scores from the Rowland Universal Dementia Assessment Scale (RUDAS) in the Indonesian setting. Indonesian older adults from a geriatric nursing center (N = 135; 52 males, 83 females; age range 60-82) completed the Indonesian translation of the RUDAS (RUDAS-Ina), following content adaptation study with community living older adults (N = 35), nine neurologists and two geriatric nurses. For face and content validity, we utilized a consensus-building procedure. Results following confirmatory factor analysis yielded a single-factor model. The reliability of scores from the RUDAS-Ina was marginally satisfactory for research purposes (Cronbach α = 0.61). Multi-level linear regression for examining the association of the RUDAS-Ina scores with gender and age indicated older age to be associated with lower RUDAS-Ina scores. In contrast, the association with gender was not significant. Findings suggest a need to develop and validate locally generated items with cultural sensitivity to the Indonesian setting, which may also be studied in other Southeast Asian countries.

Abstract
BACKGROUND The Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive test with favorable diagnostic properties for detecting dementia and a low influence of education and cultural biases. OBJECTIVE We aimed to validate the RUDAS in people with Alzheimer's disease (AD), Parkinson's disease (PD), and multiple sclerosis (MS). METHODS We enrolled one hundred and fifty participants (60 with AD, 30 with PD, 60 with MS, and 120 healthy controls (HC)). All clinical groups completed a comprehensive neuropsychological battery, RUDAS, and standard cognitive tests of each disorder: MMSE, SCOPA-COG, and Symbol Digit Modalities Test. Intergroup comparisons between clinical groups and HC and ROC curves were estimated. Random Forest algorithms were trained and validated to detect cognitive impairment using RUDAS and rank the most relevant scores. RESULTS The RUDAS scores were lower in patients with AD, and patients with PD and MS showed cognitive impairment compared to healthy controls. Effect sizes were generally large. The total score was the most discriminative, followed by the memory score. Correlations with standardized neuropsychological tests were moderate to high. Random Forest algorithms obtained accuracies over 80-90% using the RUDAS for diagnosing AD and cognitive impairment associated with PD and MS. CONCLUSION Our results suggest the RUDAS is a valid test candidate for multi-disease cognitive screening tool in AD, PD, and MS.

Abstract
OBJECTIVES This study aims to assess whether having religious beliefs, attending religious services and using spiritual-religious coping (SRC) are longitudinally associated with cognitive decline in community-dwelling older adults. METHODS A 4-year longitudinal study of 261 Brazilian older adults was conducted. Hierarchical adjusted linear regression models and logistic regression models were performed to evaluate the longitudinal effects of religious beliefs, church attendance and positive and negative SRC on cognitive decline. RESULTS The findings revealed that spiritual and religious beliefs at baseline could affect cognitive function in two different ways. When older adults use religiosity and spirituality (RS) in a functional positive manner, it results in better cognitive outcomes and a slower rate of decline. However, when used in a negative manner, it results in worse cognitive outcomes. CONCLUSION These results could help health care professionals address SRC among older adults, particularly those at a higher risk of cognitive decline. Considering that RS is very important for older adults, health care professionals should be aware of the beliefs of their patients and address RS in clinical practice.

Abstract
OBJECTIVES We investigated the utility of traditional neuropsychological tests in older uneducated/illiterate individuals without dementia to determine the possibility that they are likely not appropriate for this group. METHODS We assessed the neuropsychological performance of 1122 older adults [≥65 years old; mean age: 74.03 (SD = 5.46); mean education: 4.76 (SD = 2.5) years; women: n = 714], in the context of the Hellenic Longitudinal Investigation of Aging and Diet (HELIAD), a population-based study conducted in Greece. RESULTS We based our analyses on three groups: high-functioning/cognitively healthy (i.e., without dementia) uneducated/illiterate individuals (n = 80), high-functioning/cognitively healthy educated/literate individuals (n = 932), and low-functioning/cognitively impaired educated/literate individuals (presumably with dementia; n = 110). We used binary regression analyses with Bonferroni correction to investigate whether test performance differentiated uneducated/illiterate from educated/literate individuals. Models were adjusted for age and sex; raw test scores were the predictor variables. The uneducated/illiterate cohort was at a disadvantage relative to the healthy educated/literate group on all variables but verbal memory recognition and consolidation, congruent motor responses, and phonological fluency clustering (p > .002). Moreover, only word list learning immediate and delayed free recall and delayed cued recall differentiated the high-functioning/cognitively healthy uneducated/illiterate from the low-functioning/cognitively impaired educated/literate group, favoring the former (p's < .002). CONCLUSIONS Our findings suggest that only particular verbal memory test variables are fair in determining whether older uneducated/illiterate individuals have functional/cognitive impairment suggestive of a neurodegenerative process. On all other neuropsychological variables, this cohort was at a disadvantage. Therefore, we highlight the need for identifying appropriate methods of assessment for older uneducated/illiterate individuals.

Abstract
Background: The number of people with a migration background and dementia is increasing in Europe. All patients with suspected dementia have the right to an appropriate cognitive assessment and correct diagnosis for optimal treatment and support. Rowland Universal Dementia Assessment Scale (RUDAS) cognitive screening instrument is less affected by language, culture, and educational background, and adapted for use in multicultural populations. Objective: To compare the diagnostic accuracy of RUDAS-S to the Swedish version of Mini-Mental State Examination (MMSE-SR) for detecting dementia in a multicultural group of outpatients in Swedish memory clinics. Methods: We tested 123 outpatients (36 nonnative Swedish), in 4 memory clinics in Southern Sweden with RUDAS-S to supplement the usual cognitive assessment. Results: RUDAS-S had moderate to good diagnostic performance for detecting dementia in a multicultural population in Sweden, with an area under the receiver operating characteristic curve (AUC) of 0.81. At a cutoff score <25 its sensitivity was 0.92, specificity 0.60, and accuracy 76%. The AUC for the MMSE-SR was 0.79. At a cutoff score <23 its sensitivity was 0.65, specificity 0.81, and accuracy 73%. Conclusion: RUDAS-S is at least as accurate as MMSE-SR for detecting dementia in memory clinics in Sweden and can be used for all patients undergoing a cognitive assessment, irrespective of their cultural, language, and educational background. However, there is a need for other cross-cultural cognitive tests to complement RUDAS-S to extend cognitive examination.

Abstract
BACKGROUND Montreal Cognitive Assessment (MoCA) and Mini-Mental State Examination (MMSE) are neuropsychological tests commonly used by physicians for screening cognitive dysfunction of Alzheimer's disease (AD). Due to different imperfect reference standards, the performance of MoCA and MMSE do not reach consensus. It is necessary to evaluate the consistence and differentiation of MoCA and MMSE in the absence of a gold standard for AD. OBJECTIVE We aimed to assess the accuracy of MoCA and MMSE in screening AD without a gold standard reference test. METHODS Studies were identified from PubMed, Web of Science, CNKI, Chinese Wanfang Database, China Science and Technology Journal Database, and Cochrane Library. Our search was limited to studies published in English and Chinese before August 2021. A hierarchical Bayesian latent class model was performed in meta-analysis when the gold standard was absent. RESULTS A total of 67 studies comprising 5,554 individuals evaluated for MoCA and 76,862 for MMSE were included in this meta-analysis. The pooled sensitivity was 0.934 (95% CI 0.906 to 0.954) for MoCA and 0.883 (95% CI 0.859 to 0.903) for MMSE, while the pooled specificity was 0.899 (95% CI 0.859 to 0.928) for MoCA and 0.903 (95% CI 0.879 to 0.923) for MMSE. MoCA was useful to rule out dementia associated with AD with lower negative likelihood ratio (LR-) (0.074, 95% CI 0.051 to 0.108). MoCA showed better performance with higher diagnostic odds ratio (DOR) (124.903, 95% CI 67.459 to 231.260). CONCLUSION MoCA had better performance than MMSE in screening dementia associated with AD from patients with mild cognitive impairment or healthy controls.

Abstract
BACKGROUND The Rowland Universal Dementia Assessment Scale (RUDAS) is currently widely used for research and clinical purposes in many countries. However, its applicability and validity have not been evaluated in the Ethiopian context so far. Therefore, we designed this study to assess the reliability and validity of Rowland Universal Dementia Assessment Scale to detect major neurocognitive disorder among older people in Ethiopia. METHODS An institution-based cross-sectional study was conducted among selected older people residing in Macedonia institutional care center, Addis Ababa, Ethiopia. The gold standard diagnosis was determined using the Diagnostic and Statistical Manual of Mental Disorders criteria for major neurocognitive disorders. Stata v16 statistical software was used for data analysis. Receivers operating curve analysis, correlations, linear regression, and independent t-test were performed with statistically significant associations declared at a p-value of <0.05. Inter-rater, internal consistency reliabilities, content, criterion and construct validities were also determined. RESULTS A total of 116 individuals participated in the study with a 100% response rate. Most (52.7%) of the participants were male and the mean age in years was 69.9± 8. The Cronbach's alpha for RUDAS was 0.7 with an intra-class correlation coefficient value of 0.9. RUDAS has an area under the receivers operating curve of 0.87 with an optimal cutoff value of ≤ 22. At this cutoff point, RUDAS has sensitivity and specificity of 92.3 and 75.3 with positive and negative likelihood ratios as well as positive and negative predictive values of 3.7, 0.1, 65.5%, and 91.5%, respectively. There has also been a significant difference in the mean scores of RUDAS among the two diagnostic groups showing good construct validity. CONCLUSION The Rowland Universal Dementia Assessment Scale has been demonstrated to be a valid and reliable tool to detect major neurocognitive disorder. Policy makers and professionals can incorporate the tool in clinical and research practices in developing countries.

Abstract
This study aims to investigate whether altruism and volunteering are associated differently with cognitive functioning in community-dwelling older adults. A 2-year longitudinal study of 291 Brazilian older adults was conducted. In the baseline analysis, altruism, but not volunteering, was associated with higher scores for the composite cognitive score, the Mini-Mental State Examination, the verbal fluency and the CERAD Recall. Concerning the longitudinal analyses, volunteering at baseline, but not altruism, was associated with verbal fluency and CERAD Word List Recall after 2 years of follow up. Same results were obtained while investigating changes in score. Altruism and volunteering were associated with cognitive tests, albeit in different ways. Volunteering, but not altruism, was associated with lower cognitive decline. However, altruism, but not volunteering, was associated with higher absolute score on these tests. These findings can further understanding of this new field of health research.

Abstract
This study presents a systematic review on existing cognitive screening tools for mild cognitive impairment and dementia in populations with low education and literacy levels. Cochrane Library, PubMed and LILACS databases were examined for studies including adults aged 50 years old or older with low educational level. 61 articles were included. Despite its frequent use, studies on Mini-Mental State Examination (MMSE) revealed that educational level biased the score obtained, regardless of other factors. Separately, the Informant Questionnaire on Cognitive Decline in the Elderly, the Fototest, or the Eurotest, appear to minimize the effect of education and literacy. MMSE is unreliable for individuals with low literacy. Tasks involving reading, writing, arithmetics, drawing, praxis, visuospatial, and visuoconstructive skills have a greater educational bias than naming, orientation, or memory. An adequate determination of educational level and validation of instruments in populations with heterogeneous levels of literacy requires further research.

Abstract
BACKGROUND The Cambridge Cognition Examination (CAMCOG) is one of the most used cognitive assessment batteries for older adults. OBJECTIVE To evaluate a brief version of the CAMCOG for illiterate older adults (CAMCOG-BILL) with Alzheimer's dementia (AD) and healthy controls (CG). METHODS Cross-sectional case-control study with 246 illiterate older adults (AD [n=159] and CG [n=87], composed by healthy seniors without cognitive complaints) who never attended school or took reading or writing lessons. Diagnosis of AD was established based on the NIA-AA and DSM-5 criteria. All participants were assessed with the CAMCOG by a researcher blinded for diagnosis. To assess the consistency of the chosen CAMCOG-BILL sub-items, we performed a binary logistic regression analysis. RESULTS Both the CAMCOG and the CAMCOG-BILL had satisfactory psychometric properties. The area under the curve (AUC) was 0.932 (p<0.001) for the original version of CAMCOG and 0.936 for the CAMCOG-BILL. Using a cut-off score of ≥60 (CAMCOG) and ≥44 (CAMCOG-BILL), both instruments had the same sensitivity and specificity (89 and 96%, respectively). CONCLUSION The CAMCOG-BILL may be a preferred tool because of the reduced test burden for this vulnerable subgroup of illiterate patients with dementia.

Abstract
INTRODUCTION The accuracy of commonly used screening tests for Alzheimer's disease (AD) has not been directly compared to those that could be more appropriate for lower schooling. OBJECTIVE To compare the diagnostic accuracy of usual screening tests for AD with instruments that might be more appropriate for lower schooling among older adults with low or no literacy. METHODS The study included a clinical sample of 117 elderly outpatients from a Geriatric Clinic classified as literate controls (n = 39), illiterate controls (n = 30), literate AD (n = 30) and illiterate AD (n = 18). The tests were compared as follows: Black and White versus Colored Figure Memory Test; Clock Drawing Test versus Clock Reading Test; Verbal Fluency (VF) animal versus grocery category; CERAD Constructional Praxis versus Stick Design Test. RESULTS The means of literate and illiterate controls did not differ in the Black and White Figure Memory Test (immediate recall), Colored Figure Memory Test (delayed recall), Clock Reading Test and VF animals and grocery categories. The means of the clinical groups (controls versus AD), in the 2 schooling levels, differed significantly in most of the tests, except for the CERAD Constructive Praxis and the Stick Design Test. Diagnostic accuracy was not significantly different between the compared tests. CONCLUSION Commonly used screening tests for AD were as accurate as those expected to overcome the education bias in a sample of older adults with lower or no education.

Abstract
OBJECTIVES To quantitatively synthesize data on the accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) in different sociocultural settings and compare its performance to other brief screening instruments for the detection of dementia. DESIGN Systematic review and meta-analysis. Literature searches were performed in PubMed, EMBASE, and CINAHL from January 1, 2004 until September 1, 2019. SETTING Community, outpatient clinic, and hospital settings in high-, and low- and middle-income countries. PARTICIPANTS Twenty-six studies reporting diagnostic accuracy of the RUDAS were included with almost 4000 participants, including approximately 1700 patients with dementia. MEASUREMENTS Procedures for translation and cultural adaption of the RUDAS, and influence of demographic variables on diagnostic accuracy, were compared across studies. Bivariate random-effects models were used to pool sensitivity and specificity results, and diagnostic odds-ratios and the area under the hierarchical summary receiver operator characteristic curve were used to present the overall performance. RESULTS The pooled sensitivity and specificity for the detection of dementia were .82 (95% CI, .78-.86) and .83 (95% CI, .78-.87), respectively, with an area under the curve of .89. Subgroup analyses revealed that the RUDAS had comparable diagnostic performances across high-, and low- and middle-income settings (z = .63, P = .53) and in samples with a lower and higher proportion of participants with no formal education (z = -.15, P = .88). In 11 studies making direct comparison, the diagnostic performance of the RUDAS was comparable to that of the Mini-Mental State Examination (z = -.82, P = .41), with areas under the curve of .88 and .84, respectively. CONCLUSIONS The RUDAS has good diagnostic performance for detecting dementia in different sociocultural settings. Compared to other brief screening instruments, advantages of the RUDAS include its limited bias in people with limited or no formal education and a minimal need for cultural or language adaptation.

Abstract
ABSTRACT Objective Evaluate the accuracy of two semantic categories of the verbal fluency test (supermarket and animal categories) to separate healthy elderly individuals and lower educated Alzheimer’s disease patients. Methods We evaluated 69 older adults with less than 5 years of schooling, consisting of 31 healthy elderly, and 38 patients diagnosed with Alzheimer’s disease. Semantic verbal fluency was evaluated using the animal and supermarket categories. Mann-Whitney U and Independent t Tests were used to compare the two groups, and the diagnostic accuracy of the tests was analyzed by sensitivity, specificity, likelihood ratio’s, and the Area Under the Curve (AUC). Results We found a significant difference between the healthy older and Alzheimer’s disease groups, in both, animal (p = 0.014) and supermarket verbal fluency (p < 0.001). The supermarket category showed better overall diagnostic accuracy (AUC = 0.840, 95% CI = 0.746-0.933; p < 0.001) compared to the animal category (AUC = 0.671, 95% CI = 0.543-0.800; p = 0.014). Conclusion The supermarket category of semantic verbal fluency provides better accuracy than the animal category for the identification of dementia in a Brazilian elderly population with low educational level.

Abstract
Objectives: To evaluate the performance of the Peruvian version of the Rowland Universal Dementia Assessment Scale (RUDAS-PE) in discriminating between controls and patients with mild cognitive impairment (MCI) and dementia in an illiterate population with low-levels of education. Methods: We compared the cognitive performance of 187 elderly subjects who were illiterate (controls n = 60; MCI n = 64; dementia n = 63). Neuropsychological measures included the RUDAS-PE, Mini-Mental State Examination (MMSE), INECO Frontal Screening (IFS), and Pfeffer Functional Activities Questionnaire (PFAQ). The results were compared to a neuropsychological evaluation (gold standard), including use of Clinical Dementia Rating (CDR) scores. Results: We found a Cronbach's alpha was 0.65; Spearman's correlation coefficient was 0.79 (p < 0.01). The area under the receiver operating characteristics curve for the RUDAS to discriminate dementia from MCI was 98.0% with an optimal cut-off <19 (sensitivity 95%, specificity 97%); whereas, to differentiate MCI and controls was 98.0% with an optimal cut-off <23 (sensitivity 89%, specificity 93%). Conclusions: Based on its excellent psychometric properties, we find the RUDAS-PE suitable to aid in the opportune detection of dementia in a geriatric illiterate population with low-levels of education.

Abstract
INTRODUCTION Cognitive screening instruments are influenced by education and/or culture. In Brazil, as illiteracy and low education rates are high, it is necessary to identify the screening tools with the highest diagnostic accuracy for Alzheimer's disease (AD). OBJECTIVE To identify the cognitive screening instruments applied in the Brazilian population with greater accuracy, to detect AD in individuals with a low educational level or who are illiterate. METHODS Systematic search in SciELO, PubMed and LILACS databases of studies that used cognitive screening tests to detect AD in older Brazilian adults with low or no education. RESULTS We found 328 articles and nine met the inclusion criteria. The identified instruments showed adequate or high diagnostic accuracy. CONCLUSION For valid cognitive screening it is important to consider sociocultural and educational factors in the interpretation of results. The construction of specific instruments for the low educated or illiterate elderly should better reflect the difficulties of the Brazilian elderly in different regions of the country.

Abstract
Objective: To translate, establish the diagnostic accuracy, and standardize the Brazilian Portuguese version of the European Cross-Cultural Neuropsychological Test Battery (CNTB) considering schooling level. Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the CNTB. A total of 135 subjects aged over 60 years – 65 cognitively healthy (mean 72.83, SD = 7.71; mean education 9.42, SD = 7.69; illiterate = 25.8%) and 70 with Alzheimer’s disease (AD) (mean 78.87, SD = 7.09; mean education 7.62, SD = 5.13; illiterate = 10%) – completed an interview and were screened for depression. The receiver operating characteristic (ROC) analysis was used to verify the accuracy of each CNTB test to separate AD from healthy controls in participants with low levels of education (≤ 4 years of schooling) and high levels of education (≥ 8 years of schooling). The optimal cutoff score was determined for each test. Results: The Recall of Pictures Test (RPT)-delayed recall and the Enhanced Cued Recall (ECR) had the highest power to separate AD from controls. The tests with the least impact from schooling were the Rowland Universal Dementia Assessment Scale (RUDAS), supermarket fluency, RPT naming, delayed recall and recognition, and ECR. Conclusions: The Brazilian Portuguese version of the CNTB was well comprehended by the participants. The cognitive tests that best discriminated patients with AD from controls in lower and higher schooling participants were RPT delayed recall and ECR, both of which evaluate memory.

Abstract
OBJECTIVES To assess the psychometric properties of the Peruvian version of the Rowland Universal Dementia Assessment Scale (RUDAS-PE) to discriminate controls from patients with mild cognitive impairment (MCI) and early dementia (ED) in a population with a mid-level education. METHODS A total of 133 patients from a memory clinic were administered the RUDAS-PE, INECO Frontal Screening, Addenbrooke's Cognitive Examination, and Mini-Mental State Examination. Results were compared against a neuropsychological evaluation (gold standard). Validity measures, internal consistency, and concurrent validity were calculated. RESULTS Cronbach's α was 0.68; Pearson's ratio was 0.79 (P < .01). The area under the receiver-operating characteristics curve of the RUDAS to discriminate between ED and MCI was 89.0% (optimal cutoff at <21), whereas between MCI and controls, it was 99.0% (optimal cutoff at <24). CONCLUSIONS The RUDAS-PE has acceptable psychometric properties performing well in its ability to discriminate controls from patients with MCI and ED.

Abstract
Background Mild Cognitive Impairment (MCI) is a transitional state between normal cognition and dementia during ageing process. Early screening of elderly for MCI can help for early prevention and treatment of dementia. Rowland Universal Dementia Assessment Scale (RUDAS) is a brief cognitive assessment tool with excellent psychometric properties and is particularly useful in culturally and linguistically diverse (CALD) populations. The purpose of this study was to translate RUDAS into Nepali and to evaluate internal consistency of Nepali version of RUDAS. Methods RUDAS was translated to Nepali following recommended guidelines for translation and cross-cultural adaptation of patient reported measures. The pre-final Nepali version of RUDAS was tested on 30 elderly and appropriate changes were made by expert committee. The final Nepali version of RUDAS was developed and was administered on 100 elderly populations (mean age 67.70) to assess internal consistency. Results The rating of the participants upon their understanding of each 6 items of Nepali version of RUDAS on a 10-point Likert scale received a good score of more than 8 except ‘cube drawing’ which only received a mean score of 5.5. Additionally, only 8(27%) elderly have responded to the item ‘cube drawing’. The preference test was done and cube drawing was replaced by stick design test. Nepali version of RUDAS showed acceptable internal consistency with Cronbach’s alpha 0.7. Conclusion The results of our study presents translated and cross-culturally adapted Nepali version of RUDAS that has been proved to be an appropriate assessment tool for screening cognitive impairment among elderly.

Abstract
UNLABELLED ABSTRACTBackground:With increasing cultural diversity and growing elderly immigrant populations in Western European countries, the availability of brief cognitive screening instruments adequate for assessment of dementia in people from diverse backgrounds becomes increasingly important. The aim of the present study was to investigate diagnostic accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) in a multicultural sample and to calculate normative data as a basis for demographic adjustment of RUDAS scores. METHODS The study was a prospective international cross-sectional multi-center study. Receiver operating characteristic curve analysis was used to examine diagnostic accuracy. Regression analysis was used to assess the impact of demographic variables. RESULTS Data was collected from 341 cognitively intact participants and 80 people with dementia with a wide age- and educational range. Of the 421 included participants, 239 (57%) had immigrant background. The RUDAS had high diagnostic accuracy with an area under the curve (AUC) of 0.93. The optimal cut-off score was <25 (sensitivity 0.80, specificity 0.90). Regression analysis revealed that RUDAS scores were mainly affected by education and were unrelated to data collection site and immigrant status. Education-adjusted normative data was calculated as a basis for education adjustment of RUDAS scores. Applying education-adjusted RUDAS scores slightly but significantly improved diagnostic accuracy with an AUC of 0.95. CONCLUSION We found the RUDAS to have excellent diagnostic properties in our multicultural sample. However, we suggest that RUDAS scores should be adjusted for education to increase diagnostic accuracy and that the choice of cut-off score should be considered based on the clinical context and expected base rate of dementia.
