Public perceptions of Internet-based health scams, and factors that promote engagement with them.

The prevalence of health scams in Canada is increasing, facilitated by the rise of the Internet as a mass communication medium. However, little is known about the nature of this phenomena. Building on previous work exploring the nature of Internet health scams (IHS), this project sought to better understand the reasons why people engaged with IHS, and if contemporary psychosocial theory can help explain IHS engagement. A mixed-methods study, involving a web-based survey incorporating qualitative questions and the Susceptibility to Persuasion-II Brief psychometric scale (STP-II Brief), were administered (N = 194) in British Columbia, Canada, in 2017. Results (n = 156) demonstrated that 40% of participants had ever engaged with IHS, but only 1% reported to have actually lost money to a deceptive product/service. Associations between scam engagement, participant demographics and STP-II Brief scores were explored, with Sex and Employment Status both found to have a significant effect on odds of IHS engagement. STP-II Brief scores were positively correlated with a likelihood of engagement with IHS, even when adjusting for demographic characteristics. The types of IHS most frequently engaged with were those related to body image products, and social influence appeared to be a dominant psychosocial factor promoting engagement. Participants reported that claims of products being 'natural', the result of scientific breakthroughs, use of pseudoscientific language, use of testimonials, and celebrity or professional endorsement could lead them to engage with a product. These findings can help inform health professionals' understanding of public health-seeking behaviours with respect to deceptive marketing.
