Process evaluation of an innovative healthy eating website promoting the Mediterranean diet

The Internet offers a promising medium for delivering nutrition education. This study aimed to evaluate user perceptions and usage patterns of an innovative healthy eating website promoting the Mediterranean diet. The website was evaluated over a 6-month period by female employees of University of Glasgow, aged 25-55 years. User satisfaction with the website was evaluated using a triangulation approach, including website visit counts, questionnaires (31 participants) and focus group interviews (18 participants). Although login frequency decreased over the 6-month study, questionnaires revealed that most sections of the website were viewed as being very helpful and the majority of participants perceived the overall website to be extremely interesting, informative, novel, trustworthy, easy to understand, useful, user-friendly, attractive and encouraging. The recipes section was the most visited and lack of time was the main barrier to using the website on a weekly basis, as recommended. The results of the questionnaires were confirmed by measures of website usage and the feedback provided by the focus group interviews. Several features that would improve the website, such as increased interactivity, nutritional analysis and fruit and vegetable serving content of recipes and more regular updates, were identified from the interviews and will inform future refinements of the website.
