Today there are over 300,000 people in the UK living with Inflammatory Bowel Disease (IBD) in the form of either Crohn’s Disease or Ulcerative Colitis , and there is a further 1,500,000 patients living in the USA . IBD is a lifelong, incurable illness that causes patients to suffer with unpredictable inflammation in their digestive tract [1,3,4]. Stigmatising symptoms include, but are not limited to diarrhoea, abdominal pain, fatigue and nausea [1,2,3,4]. There is no one treatment and often patients undergo a range of medications and procedures, including surgery, to reduce inflammation and symptoms. It is an illness that impacts on all areas of life from work to intimate relationships with people often feeling alone in their battle .
Internet technologies, namely social media platforms, have helped connect thousands of people all over the world with chronic illnesses like IBD. Patients seek informational and emotional support, researching and coming to understand how to live with the illness [6,7]. However conversations that would once take place in purpose built forums such as crohnsforum.com are migrating towards more commonly used social media platforms such as Facebook, Twitter and Instagram. These platforms are fundamentally not designed to host conversations around health, but have been adapted to suit user needs.
Social media platforms’ business model relies on the aggregation, processing and selling of user data to partner companies including Experian  and to advertising companies. While many users are aware of targeted advertising  there is a lot uncertainty over what companies do with their data . It has been examined that he majority of social media users do not read the Terms and Conditions prior to accepting them [10,11] and many are left with optimistic and naive expectations of how companies process and use their data . Digital economy researchers warn of the uncertainties over how algorithms may impact people’s real life and potentially cause harm . For patients who share sensitive information about their health, they are more vulnerable to the outcomes of surveillance capitalism .
My PhD research is two-fold: while there has been ample research in how web-based forums have been used by support groups [13,14,15,16], there is little knowledge in how patients leverage contemporary social media platforms for informational and emotional support. Secondly, my research also examines patients’ perceptions of who can see the information they post about their health and what the social media platforms may do with this data.
My first exploratory study, when I interviewed 38 members from the IBD community spanning across Facebook, Instagram and Twitter, explored how patients use the functionality of each technology to suit their needs according to the SCENA Model of Affordances in Social Media . Comprehensive thematic analysis indicated that connectivity functions underpin many of the therapeutic outcomes of engaging with online health communities; however, character limits and privacy settings play an important role in self-presentation and disclosure. The second arm of the study was to better understand how patients perceive notions of social and institutional privacy. Participants demonstrated a strong understanding of social privacy, describing their preferences and behaviours to mitigate risks that they perceive. Understanding of the digital economy was mixed, ranging from little or no understanding, to the recognition of advertising, with a small number of specialists (who work in online advertising and cybersecurity) who were much more data literate. Despite the mixed understanding, the findings suggest that patients perceive there is much more to benefit from self-disclosing health information on social media than risks.
While patients clearly care about privacy, the mixed attitudes and behaviours towards institutional privacy warrants further exploration. With the rapidly changing landscape of privacy protections with an increased number of media articles, the next study will explore the concerns shared by charities that host support groups on contemporary social media platforms. These findings, coupled with patient concerns will inform an intervention to increase awareness to patients while simulatenously providing them with tools to mitigate some of the risks.
