The development, validation and assessment of a food literacy questionnaire (IFLQ-19)

The purpose of this thesis was to develop a food literacy questionnaire consistent with an internationally agreed upon conceptualisation and investigate the relationship between food literacy, diet quality and food security in Australian adults. Four studies were conducted to determine content validity, face validity, targeting, responsiveness, validity and reliability. This resulted in the 100-item International Food Literacy Questionnaire, the IFLQ-19. A weak, positive correlation was found between food literacy and diet quality and food security. Areas for future work include improving the usability of the IFLQ-19 and developing interventions to improve diet quality and food security
