However, it is currently unclear how online social networks may best be harnessed to achieve health behavior change. OBJECTIVE The intent of the study was to systematically review the current(More)
Previous research has shown that providing family engagement and social support play important roles in weight management success, helping to achieve long-term lifestyle changes. Traditionally, the support provided by online health communities is primarily targeted at individuals and does not involve their families. We are proposing SOFA (SOcial FAmilies),(More)

OBJECTIVE To determine whether(More)
In recent years, much work has been carried out in interface design and service quality in order to maximise user experience and sustain engagement. We are often unsure, however, what factors really influence user interactions with the technologies.

Along with the smart phone came smart phone applications, which range in functionality, complexity and price. Hugely popular are lifestyle applications which include tools for diet and exercise.

However, it is possible that time-extension could increase the amount eaten in the absence of social effects. Therefore, the aim of this study was to assess whether(More)
BACKGROUND The prevalence of health-focused mobile phone apps available for download increases daily, with weight management apps being among the most proliferative. However, most lack theoretic grounding or evidence of efficacy. There is a significant body of literature which provides evidence for behaviors which are associated with successful weight loss(More)
