Abstract: To support nutrition-related behavioural change, a dietitian can offer tailored educational programmes based on patients| specific dietary behaviours. A model has been developed to integrate learning technologies into this process. This tool allows patients to self-report their dietary intake, creating awareness, and to receive individually tailored dietary advice from their General Practitioner (GP) via a dietitian, to assist with change. This article examines how a step-wise approach to the interface design has allowed a multidisciplinary approach to automated dietary assessment to be undertaken. Concentrating on the identification of core foods and on the questionnaire format using an outline of the diet history interview, the design features of the programme used focus groups with end users and in-depth discussion between the multidisciplinary team. The development of an online self-administered dietary assessment programme must ensure outcome goals are met whilst upholding the simplicity of the interface design to allow a larger number of patients access to the programme.
