Abstract

Background: Parkinson’s disease (PD) is the second most common neurodegenerative disorder worldwide, with an increasing disease burden in Southeast Asia. To date, no standardized and culturally adapted PD screening instrument is available for the Vietnamese population. The Australian Parkinsonism Screening Questionnaire is a brief instrument that has been validated in community settings and applied across diverse cultural contexts. Objective: To translate and culturally adapt the Australian Parkinsonism Screening Questionnaire into Vietnamese in accordance with the guidelines proposed by Beaton et al. (2000), thereby producing a Vietnamese version suitable for subsequent validity and reliability studies. Methods: The study followed the cross-cultural adaptation process described by Beaton et al. (2000): (I) two independent forward translations (T1 and T2); (II) synthesis of the translations (T-12); (III) two independent back-translations by native English speakers (BT1 and BT2); (IV) expert committee review; and (V) field testing with cognitive interviews involving 30 participants; (VI) submission of the complete documentation to the original questionnaire developer for review. Results: The T-12 version was synthesized from two independent forward translations. Both back-translators confirmed that its content was equivalent to that of the original questionnaire. The expert committee approved the pre-final version. One modification to ensure experiential equivalence was made during Stage II: the term “screwdriver” was replaced with “chopsticks” to better reflect the Vietnamese cultural context. Field testing in 30 community-dwelling participants showed that no item reached the predefined incomprehensibility threshold of ≥15%. Minor wording refinements were made to 5 of the 11 items, and no item was removed. All participants completed the questionnaire independently. The original questionnaire developer acknowledged receipt of the documentation and requested no further revisions. Conclusion: The Vietnamese version of the Australian Parkinsonism Screening Questionnaire was judged by the expert committee to demonstrate semantic, idiomatic, experiential, and conceptual equivalence to the original version and to be appropriate for the Vietnamese cultural context.
