Dietary acculturation scale 2.0 for international students: cross-cultural validation incorporating food insecurity and eating well-being constructs Tumuli Iulio Princess Margaret Hospital, Funafuti Island, Private Mail Bag, Tuvalu Email:tumshinaiulio@gmail.com ——————————————————————————————————————— Abstract This study developed and validated the Dietary Acculturation Scale 2.0 (DAS-2.0), a multidimensional instrument designed to assess dietary acculturation among international university students. A total of 298 valid responses were analyzed following established scale development procedures. The revised scale integrates three conceptual domains: behavioral dietary adaptation, food insecurity and structural access, and eating well-being. Exploratory factor analysis supported a three-factor structure, which was subsequently confirmed using confirmatory factor analysis. The scale demonstrated satisfactory internal consistency, convergent validity, discriminant validity, and cross-cultural measurement invariance across major regional groups. Preliminary criterion-related validity was supported through significant correlations with self-rated health and dietary satisfaction indicators. By incorporating structural and experiential dimensions, the DAS-2.0 extends prior dietary acculturation measures and provides a psychometrically sound tool for international student research.
