Article Abstract
Objective: This study aims to validate the Thai translation of the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS).
Methods: The English version was translated into Thai and then back-translated into English. The translated version underwent 2 rounds of cognitive pretesting to assess the ease of comprehension, ease of use and comfort with the scale. Then, it underwent large clinimetric testing.
Results: The Thai version was validated in 354 PD patients. The comparative fit index (CFI) for all four parts of the Thai version of the MDS-UPDRS was 0.93 or greater. Exploratory factor analysis identified isolated item differences in factor structure between the Thai and English versions.
Conclusion: The overall factor structure of the Thai version was consistent with that of the English version based on the high CFIs (all CFI ≥ 0.90). Hence, it can be designated the official Thai version of the MDS-UPDRS.

Background: Although the 12-item Short Form Health Survey version 2 (SF-12v2) is suitable for measuring health status in the general Thai population, it has been evaluated using classical test theory. Rasch analysis, however, offers a psychometric testing method that converts ordinal scales to interval-level data without breaching parametric assumptions. Thus, this study aimed to assess the measurement properties of Thai SF-12v2 and SF-6D items derived from it among the general Thai population.

Health literacy (HL) is a fundamental factor in raising health awareness and self-management, especially in contexts with increasingly complicated health systems. Its accurate and culturally appropriate measurement is necessary to support effective medical interventions. Accordingly, we translated the Health Literacy Questionnaire (HLQ) into Vietnamese and analysed its psychometric properties on the basis of data derived from respondents who completed the translated instrument.

Background: Dysphagia, or swallowing difficulty, is common among older adults and can pose risks during dental treatments, including aspiration and accidental ingestion. While dysphagia prevalence is well-studied in healthcare and community settings, data from clinical dental settings remain limited. This study aimed to determine the prevalence of swallowing difficulties in older adults visiting a dental clinic.

: The allele is strongly linked to severe cutaneous adverse reactions (SCARs) during allopurinol treatment, and it has been associated with the A allele of rs9263726 (G>A). Paraclinical characteristics of gout are indicative of associated comorbid conditions. This study investigated the genotype frequency of and its association with paraclinical characteristics and rs9263726 in gout patients from Northeast Vietnam.
