Consumers will engage with sites they deem trustworthy and turn away from those they mistrust. In this paper we present a framework for understanding trust factors in web based health advice. The framework is derived from a staged model of trust and allows predictions to be made concerning user engagement with different health websites. The framework is then validated via a series of qualitative, longitudinal studies. In each study genuine consumers searched online for information and advice concerning their specific health issue. They engaged in free searching and were directed towards sites previously reviewed using the framework. Thematic analysis of the group discussions provided support for the framework and for the staged model of trust wherein design appeal predicted rejection (mistrust) and credibility of information and personalisation of content predicted selection (trust) of advice sites. The results are discussed in terms of the merits of the framework, its limitations and directions for future work.

Traditionally, authoritative health information has been based on facts and figures, not the experiences of patients. However the rise of patient-generated content on the Internet, in the form of online patient experiences (PEx) has changed the landscape of health decision-making. Online PEx can have both positive and negative influences -PEx can enhance social support, and facilitate adjustment to an illness but can also raise anxiety levels and in an unmoderated format can deliver very powerful but misleading messages. PEx is important for researchers and e-health designers alike and in this workshop we seek to bring the new PEx community together to share new approaches and findings.

This paper is concerned with those factors capable of influencing people's response to online advice. It describes a survey of over two and a half thousand people who had actively sought advice over the Internet. A framework for understanding trust in online advice is proposed in which three key factors -source credibility, personalisation and predictability -are shown to predict whether or not people actually follow advice given online.

The level of consistency - or degree of user complexity - of any command language is usually defined using one of a number of formal grammars, and yet consistency need not be so rigorously defined. It is proposed that diagrams can provide a suitable meta-language with which to illustrate the consistent properties of any command set; and a particular type of diagram - the 'command wheel' - is described. Command wheels offer a number of advantages over formal specifications, being simple to construct and allowing more discretion in the design process. In a study of word-processor users, it was found that properties of command wheels allowed the accurate prediction of user's behaviour, both in terms of their on-line performance, and their subsequent ability to recall commands.

Gerontechnology 2010;9(2):309; doi:10.4017/gt.2010.09.02.153.00 Purpose Aging is generally associated with a decrease in mobility and social interaction 1 ; this decrease can be dependent upon health and social factors. Sustaining levels of activity is important for successful ageing, those with mobility problems suffer in a variety of ways. Social lives become restricted and the less mobile become limited in terms of their access to nutrition, leisure and other activities, leading to dependence on others 2 for visits to shops and to other services 3 . Although mobility is an issue for ageing there are two gaps in knowledge. First, relatively little is known about mobility in the oldest-old and secondly there are methodological problems in that determining the extent to which older people are active in their environment has been limited largely to self-report studies. The aim of this study was to utilise innovative methods (activity monitoring methods combined with data from state-of-art location-aware technologies) in order to develop new metrics for mapping the mobility of the oldest-old members of an existing 20 year longitudinal study of aging 4 . Method 86 survivors (aged 72-92 years old) of a 20 year longitudinal study of aging participated (mean age 79 years). Participants attended two laboratory assessments to assess gait, balance and cognitive ability and then wore an accelerometer and a locationaware device for 7 days. The accelerometer monitored their sitting, stepping and standing movements and the i-locate device noted journeys made outside of the home through use of GPS. Participants also provided information on a range of other health and well-being measures and completed time use diaries noting activities and journeys. Results & Discussion Cognitive ability, health and well-being measures demonstrated that participants were successfully aging. Activity profiles were comparable to earlier reports for healthy older adults and within recommended physical activity guidelines. Self-reported levels of activity, measured by the CHAMPS questionnaire, were similarly comparable. Regression analyses show that a measure of single leg balance is the best predictor of mobility as measured by both the accelerometer and time use diaries whereas gait speed, health and performance on a 'Timed up and Go' test which measures 'functional mobility' were the best predictors of distance travelled away from home. Further analyses will examine whether data gathered longitudinally over the past 20 years can predict current mobility and successful aging.
