“…In a computer-assisted diabetes program implemented in Germany, most participants incorrectly answered questions concerning the caloric and/or carbohydrate content of foods and meals even after the training program. 22 After a second repetition of the skill, Ͼ80% of the German participants still answered incorrectly, whereas in our study approximately 60% of participants identified the correct meat choice, 50% identified the correct milk and vegetable choices, 40% identified the correct fruit choice, and 20% identified the correct starch choice on their first attempt. When our participants completed this skill two or more times the percentage who identified the correct food choice increased for all food groups, most notably the meat and vegetable choices, which both increased to 75% correct.…”

"Your Guide to Diet and Diabetes" filled a need for an easy-to-use website that addressed the issues of diet and diabetes. Based on the number of visits to the login page (n = 6,124) and number of individuals who answered demographic questions, the site was well received. While a smaller group of participants elected to complete the interactive knowledge and skills questions, responses to these questions demonstrated that participants obtained knowledge from the website. In particular, participants increased their knowledge of food sources and appropriate serving sizes of carbohydrate. The "making a plate" skill activity was used with much greater frequency than the more conceptually complex carbohydrate counting skill activity.

“…Some studies have suggested that people can count carbohydrate with reasonably accuracy (i.e. within 10-15 g or 15%-20% of the true value) (Brazeau et al, 2013;Mehta, Quinn, Volkening, & Laffel, 2009;Rabasa-Lhoret et al, 1999;Smart, Ross, Edge, King, et al, 2010), while other studies suggested that people were very inaccurate (Shapira et al, 2010) and at best only up to half of people could accurately estimate carbohydrate content (Bishop et al, 2009;Nebel et al, 2002).…”

“…Other studies have found 50% had taken an entry level computer course in school (average age 28±4 years female, 29±5 years male) (Fong and Kretsch, 1990), indicating a moderate level of general computer exposure. Lack of computer experience however is a key indicator of negative enjoyment of computerised dietary programs (Nebel et al, 2002), yet experience is not related directly to acceptance of use, and should be concurrently assessed.…”

“…Positive outcomes for participants of diabetes education and assessment were found. Increased comprehension of nutrition messages and a higher degree of practicability were identified (Nebel et al, 2002). However, skills such as the ability to use a keyboard, mouse and or menus of a computer system do need to be considered when developing a program and determining its usability.…”

A dietary assessment website for use in the primary healthcare setting has been developed. The website allows patients, referred from their GP, to self-report their dietary intake. Data from the website feeds to a dietitian who develops individualised dietary advice for the patient. The aim of this paper is to describe the usability testing of the dietary assessment website with its potential users. Testing was broken into two phases. Fortytwo free-living adults with metabolic syndrome volunteered, 17 completed phase one and 10 completed phase two, with a 64% rate of completion. Phase one participants spoke aloud as they progressed through the selfadministered dietary assessment website under researcher observation. Observed difficulties in website use and need for assistance was recorded and the website underwent modifications between phases. Only four participants in phase 1 required large amounts of assistance. Phase two participants progressed through the website without observation or using the think-aloud protocol. This simulated the environment in the GP practice within which the website was to be implemented. All participants completed pre-and post-use questionnaires assessing feelings toward use, computer experience and problems encountered. Questionnaires were thematically analysed for relationships between website use and participant feelings. Time taken to use the website was recorded automatically. Website features were grouped into 'action classes' e.g. selecting food items, and times taken were calculated for each class. Comparisons (t-tests) were made between the action classes for the two phases. Average time taken to select the food items was 31mins and 24mins for phase one and two respectively. Total time taken was approximately 1 hour and varied by four minutes between phases. Time taken to complete the dietary assessment was comparable to a face-to-face diet history with a dietitian. The website was found to be highly user-friendly with little assistance being required for most levels of computer experience. Dietary management may be overlooked by GPs, yet by offering different methods of accessing dietitians, management may improve. completed phase one and 10 completed phase two, with a 64% rate of completion.Phase one participants spoke aloud as they progressed through the self-administered dietary assessment website under researcher observation.
