Development and process evaluation of an internet-based physical activity behaviour change program.
OBJECTIVE
Limited research exists addressing issues of website development and attitudes towards websites that promote physical activity. This paper describes the design and process evaluation of a physical activity intervention, from a randomised trial (RT) that examined the effectiveness of delivery modes (face-to-face, Internet-mediated (combined Internet and face-to-face) and Internet-only).


METHODS
Evaluation surveys were completed at the end of the RT intervention (n=159), and a random sample (n=23) participated in focus group discussions. Differences were assessed using ANOVA, t-tests, and qualitative analysis.


RESULTS
Face-to-face participants were more satisfied with their group allocation than the Internet groups. Internet groups reported accessing the Internet at home, and that they liked the self-paced nature of the website. Difficulties associated with time and motivation were raised by the Internet groups. No differences were found for content acceptability and credibility. Website usability scores were high for both Internet groups.


CONCLUSIONS
These findings support the use of the Internet in terms of content satisfaction and usability; however, issues were raised regarding the acceptability of an Internet-based program when traditional face-to-face delivery options are available.


CONCLUSIONS
Identifying avenues to support user perceptions of 'motivation', and mechanisms for enhancing engagement and retention, and user acceptability are required.
