Evaluation of a web-based lifestyle coach designed to maintain a healthy bodyweight
Abstract
We evaluated a web-based intervention, the Healthy Weight Assistant (HWA), which was designed to help people with a healthy bodyweight, or those who are slightly overweight, to achieve and maintain a healthy weight. Four evaluation methods were used: (1) pre- and post-test questionnaires; (2) real time usability-tests; (3) log-file analysis; (4) qualitative analysis of forum posts, email messages and free-text responses in the questionnaires. A total of 703 respondents received access to the HWA. Six weeks after receiving access, 431 respondents completed a second questionnaire. The enthusiastic responses showed that many people were interested in using an interactive online application to support achieving and maintaining a healthy weight. The preliminary results suggest that improvements with respect to motivation may lead to large effects, yet require only small changes in the design of the HWA. Sending automatic tailored reminders may enhance motivation to keep using the application. Motivation to change behaviour may be enhanced by emphasizing goal setting and visualizing progress.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
