Cultural validation of the Addenbrooke's Cognitive Examination Version III Urdu for the British Urdu-speaking population: a qualitative assessment using cognitive interviewing.

ABSTRACT: OBJECTIVES:Our research determined whether the Addenbrooke's Cognitive Examination Version III (ACE-III) Urdu eliminated cultural bias through a qualitative assessment of its understanding and acceptability within the British Urdu-speaking population, employing cognitive interviews. METHOD:We aimed to recruit 25 participants fluent in speaking and writing Urdu, over the age of 60 years, able to give informed consent and who did not have a history of cognitive impairment. Participants were administered the ACE-III Urdu, and cognitive interviews were conducted, which involve obtaining verbal data on the individual's perception of the assessment overall, their understanding of the mental processes behind how they interpreted questions within the assessment and how they produced appropriate responses. This allows us to gauge the participants' overall thoughts on the Urdu ACE-III before applying question-formatted prompts to every ACE-III Urdu item. RESULTS:We recruited 25 participants, 12 women (48%), ranging from ages 60 years to 85 years (M=69.12, SD=6.57), all from Greater Manchester. Participants came from varied socioeconomic backgrounds, with 22 identifying as Pakistani, one as British Pakistani and two as East African. Across 19 ACE-III Urdu items, 7 required changes based on participant feedback: item 5a: fluency; items 6, 18 and 19: memory; items 12 and 13: language; and item 17: visuospatial abilities.The need for some of these changes was realised after 21 participants, due to persistently reoccurring issues, and these were applied before the last four participants. Overall, the ACE-III Urdu was considered easy and straightforward by all 25 participants, who understood items and felt the ACE-III Urdu was appropriate, not just for them, but for British Urdu speakers in general. CONCLUSION:Our cognitive interviews determined the ACE-III Urdu was acceptable, especially with regards to cultural context, but further changes were made to ensure understanding. Therefore, we adapted the ACE-III Urdu in accordance with feedback, resulting in our finalised version being culturally validated.

Project description:Objective: Age-related disorders, such as dementia, significantly contribute to the global burden of disease. Adequate screening in the primary care setting is critical for early detection and proper management. The Addenbrooke's Cognitive Examination III (ACE-III) is an open-source neuropsychological test with superior diagnostic quality in comparison to the Mini-Mental State Examination (MMSE). Our aim was to perform a guideline-conform English-German translation and cultural adaptation of the ACE-III in order to enable implementation in German-speaking countries. Methods: The translation and cultural adaptation were performed in accordance with the "Principles of Good Practice for the Translation and Cultural Adaptation Process for Patient-Reported Outcomes (PRO) Measures" from the International Society for Pharmacoeconomics and Outcome Research (ISPOR) (Wild et al. 2005). Four separate English-German translations were compiled into one German consensus translation, which was then translated back into English and compared to the original English version. After comparison, the German consensus translation was revised with emphasis on the identified differences between the English original version and the English translated version. This revised German consensus translation was subsequently evaluated for clinical applicability on a 5-point scale (0 - not applicable; 5 - applicable without any restrictions) by 20 practitioners experienced in the field of neuropsychological testing, using an anonymized, paper-based 22-item survey. Results: Nineteen of the 20 practitioners (95.0%) rated the German ACE-III translation as overall applicable. The median rating was 4.0 [IQR (4.0/5.0)]. When evaluating survey items assessing the applicability of the individual 19 subtests of the ACE-III, all of them (100%) were rated as applicable with a median rating of 4.5 [IQR (4.1/4.9)]. Conclusion: The German ACE-III translation in its current form is generally applicable and can be utilized for clinical and scientific purposes.

Project description:The Addenbrooke's Cognitive Examination III is a brief cognitive screening tool that is widely used for the detection and monitoring of dementia. Recent findings suggest that the three variants of primary progressive aphasia can be distinguished based on their distinct profiles on the five subdomain scores of this test. Here, we investigated the utility of the Addenbrooke's Cognitive Examination III to differentiate the primary progressive aphasia variants based on their item-by-item performance profiles on this test. From these results, we created an interactive primary progressive aphasia Addenbrooke's Cognitive Examination III calculator which predicts the variant based on a patient's unique item-by-item profile. Twenty-eight logopenic variant, 25 non-fluent variant and 37 semantic variant primary progressive aphasia patients and 104 healthy controls completed the Addenbrooke's Cognitive Examination III at first clinical presentation. Multinomial regression analyses were conducted to establish performance profiles among groups, and R Shiny from RStudio was used to create the interactive Addenbrooke's Cognitive Examination III diagnostic calculator. To verify its accuracy, probability values of the regression model were derived based on a 5-fold cross-validation of cases. The calculator's accuracy was then verified in an independent sample of 17 logopenic, 19 non-fluent and 13 semantic variant primary progressive aphasia patients and 68 Alzheimer's disease patients who had completed the Addenbrooke's Cognitive Examination III (or an older version of this test: Revised) and had in vivo amyloid-PET imaging and/or brain autopsy pathological confirmation. Cross-validation of cases in the calculator model revealed different rates of sensitivity in classifying variants: semantic = 100%, non-fluent = 80.6% and logopenic = 79.9%; healthy controls were distinguished from primary progressive aphasia patients with 100% sensitivity. Verification of in vivo amyloid and/or autopsy-confirmed patients showed that the calculator correctly classified 10/13 (77%) semantic variant, 3/19 (16%) non-fluent variant and 4/17 (24%) logopenic variant patients. Importantly, for patients who were not classified, diagnostic probability values mostly pointed toward the correct clinical diagnosis. Furthermore, misclassified diagnoses of the primary progressive aphasia cohort were rare (1/49; 2%). Although 22 of the 68 Alzheimer's disease patients (32%) were misclassified with primary progressive aphasia, 19/22 were misclassified with the logopenic variant (i.e. falling within the same neuropathological entity). The Addenbrooke's Cognitive Examination III primary progressive aphasia diagnostic calculator demonstrates sound accuracy in differentiating the variants based on an item-by-item Addenbrooke's Cognitive Examination III profile. This calculator represents a new frontier in using data-driven approaches to differentiate the primary progressive aphasia variants.
