Objective: Interest in the management of dementia is expanding due to an increase in the elderly population and consequently an increase in the number of dementia population. Seeing that early detection closely interferes with clinical outcomes, selection of screening tools is critical. The purpose of this study was to develop a Korean version of the Rowland Universal Dementia Assessment Scale (RUDAS-K), which is unaffected by education level, language, and culture, along with assessing frontal function and visuospatial aspects.
Methods: The translation process was carried out in nine stages. In the first stage, three occupational therapists translated the original RUDAS into Korean, followed by another occupational therapist collecting three translations. For the third stage, one rehabilitation specialist examined the discrepancy between the original and the translated version. In the fourth stage, verification questionnaires (each question consisting of one sentence from the original RUDAS in English followed by one sentence translated into Korean) were surveyed to find out the similarity betweenthe original text and the Korean translation. In the fifth stage, the Korean translation was revised based on the questionnaire results, and comprehension questionnaires were conducted. In the seventh stage, the three-person translation verification committee confirmed the suitability of Korean translation and subsequently had a professional translator provide a back translation of RUDAS-K. Lastly, an English native speaker and a bilingual occupational therapist verified the similarity of semantics between the original and the back translation.
Result: After the first and second stage of translation, RUDAS-K underwent the first consensus verification process, revised the sentences with the lowest scores. Sentences with literal translation were simply revised. Missing texts were paraphrased and added to the liberal translation. Indicating the revised sentences and ones with the lowest score on the comprehension questionnaire, RUDAS-K was sent to the verification committee. As a result, the English education professor and the Korean language professor provided advices on the official Korean language notation while the occupational therapy professor suggested some revision based on vocabularies often found in evaluation used by healthcare professionals. There were no changes made to RUDAS-K after comparing original RUDAS to the back translation. There was one difference in meaning for the translation of “tea” in Korean; it was changed to “green tea" instead of “tea" for the direct translation of “tea” in Korean hold two different meanings.
Conclusion: RUDAS-K, which has undergone a systematic translation process, is expected to be a useful and versatile screening tool for those suspected with dementia.
