Objectives: Psychometric Validation of the Escala de Literacia da Alimentaç˜ ao e Nutriç˜ ao (E-LAN), addressing the current lack of validated instruments for assessing food and nutrition literacy among portuguese youth. Study design: Cross-sectional. Methods: The study was conducted in a school setting in the western region of central Portugal between April 10 and 12, 2024, using a convenience sample of children aged 10–12 years. The E-LAN comprises 49 items (42 Likert-scale and 7 multiple-choice) across seven subscales assessing cognitive and skills domains. Reliability was examined using Cronbach's α , and confirmatory factor analysis (CFA) was performed to evaluate the internal structure, using χ 2 /df, AGFI, CFI, TLI, and RMSEA as fit indices. Results: The initial scale showed good internal consistency (Cronbach's α α =0.875). Four items were removed due to low item-total correlations and factor loadings. The revised 38-item version demonstrated improved reliability (Cronbach's =0.889), acceptable inter-item correlations, and good model fit ( χ 2 /df = 1.45; AGFI = 0.91; CFI = 0.93; TLI = 0.91; RMSEA = 0.06). Conclusions: The E-LAN is a concise, reliable, and valid tool for assessing food and nutrition literacy among portuguese youth, supporting its use in public health research and interventions.
