Probelems: reflecting on a technology probe into peer involvement in cardiac rehabilitation

Given the widely acknowledged impact that social support has on health outcomes, we set out to investigate peerinvolvement in cardiac rehabilitation and explore the potential for technological support thereof. We planned to deploy a purpose built technology probe into a 10-week rehabilitation program. This paper presents the findings of the probes pilot study, where rejection of technology and reluctance to involve peers highlighted important considerations for the design of peerbased health promotion technologies and methodological considerations for the study of peer-involvement in behavioural change as well as pervasive health research in general.
