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.
