Printed leaflets more impactful in increasing sun safety knowledge than social media
April 26, 2019
Abstract
This study describes a randomised control trial investigating whether printed leaflets or social media are more effective in increasing knowledge of the risks of sun exposure and melanoma in people aged 18–29. The study participants were 18–29-year-old university students or graduates, recruited in London. A baseline level of knowledge was measured using the Skin Cancer and Sun Knowledge questionnaire. Study participants were then randomised into either a leaflet arm or Facebook arm. Identical information was delivered through a SunSafe campaign via either posted leaflets or Facebook during a 10-day exposure window. Following this, participants repeated the Skin Cancer and Sun Knowledge questionnaire. Following the SunSafe intervention, the mean knowledge score improved in both groups to a statistically significant degree (Facebook=1.82, leaflets=3.04, P<0.001). Moreover, the improvement in knowledge score of the leaflet arm was statistically significantly greater than in the Facebook arm (95% confidence interval: 0.35–2.09, P=0.0059). Participants of lighter skin colour demonstrated greater levels of knowledge about skin cancer and sun exposure at baseline (P=0.005; P<0.05). There was no correlation between sex and baseline knowledge (P=0.7725). There was no significant effect of skin tone or sex on the knowledge change (P=0.139 and 0.643). The findings suggest that printed information in the form of leaflets is more impactful in increasing knowledge than online platforms such as Facebook among a young adult demographic in the UK. These findings should be considered when designing public health campaigns, acting as a reminder to not neglect traditional media in health promotion.
