Abstract: Mobile device proficiency is critical for older adults’ well-being, independence, and social connectivity. The Mobile Device Proficiency Questionnaire (MDPQ) is widely used but shows factor structure inconsistencies across cultures, and no validated Chinese version existed despite China’s unique digital ecosystem. This study translated and psychometrically validated the MDPQ for Chinese older adults. The MDPQ was translated and evaluated with 792 Chinese older adults (mean age = 67.08 years; 70.6% female) using a multi-method approach combining Classical Test Theory (exploratory factor analysis, confirmatory factor analysis, and Exploratory Structural Equation Modeling) and Rasch analysis. The Chinese MDPQ revealed a culturally relevant three-factor structure comprising 31 items: Basic Operations, Email Management, and Advanced Functions. Rasch analysis identified monotonicity violations in the original five-point response scale, leading to a collapsing of response categories from five to three points to improve measurement precision. Adequate external validity was demonstrated through medium to large correlations with frequency of internet use and eHealth literacy. The adapted Chinese MDPQ demonstrated satisfactory psychometric properties, supporting its use for assessing mobile device proficiency among Chinese older adults. The findings suggest that adapting mobile device proficiency measures requires careful consideration of domestic digital ecosystems and usage contexts, as cultural and technological factors influence both the structure and scaling of such instruments.
