The distributed content revolution is the mobile revolution, a new paradigm that puts the user at the center of the Internet and turns usability and the quality of content into the aim of digital strategy.
This study attempts to address this issue by using an experimental design to investigate the relationships among recruitment web site orientation, individuals' expectations concerning the use of Internet technology, web site usability, and organizational attractiveness.
Furthermore, social engagement, active use of the Internet [ 39] and usability of the web page [ 40] may affect participation in web intervention studies.
Primary and secondary outcome measures will be assessed by self-report at baseline, 3 months and 12 months, and include: physical activity behaviour, height and weight, Internet self-efficacy, website usability, website usage and quality of life.
These measures will include PA behaviour, height and weight (to calculate the body mass index), Internet self-efficacy, website usability (only assessed at 3-month and 12-month follow-up periods), and quality of life.
Our findings extend the body of research on usability of Internet-based mental health interventions to show that remote usability testing can produce valuable data and allow for testing with a geographically diverse group.
For internet-based health interventions, usability testing is essential to ensure that patients' needs are met and that they are able to navigate the website appropriately and efficiently [ 9].
In evaluation studies, 66% are usability studies in Internet applications; this is partially because usability studies on Internet started relatively early in western countries.
Website engagement and retention will be assessed using various website statistics, self-reported internet self-efficacy and website usability.
Wengberg (9), utilizing an computer diabetes intervention, has suggested that self-efficacy may function as a moderator for diabetes behavior change, and Gerber et al. (10) have demonstrated usability of an Internet program for young inner-city adults.
