The congruency hypothesis posits that approach-orientated individuals are persuaded to engage in prevention behaviours by positively framed messages; conversely, negatively framed messages are more persuasive in encouraging those who are avoidance-orientated. A 2 (frame: loss vs gain) × 2 (motivation: avoidance vs approach) design examined the effects of skin cancer information on sun-protective intentions and free sunscreen sample requests among 533 young adults. Gain-framed messages had the strongest effect on sun-protective intentions for approach-oriented individuals, whereas loss-framed messages had the strongest effect on avoidance-oriented individuals. Message framing effects on precautionary sun behaviour intentions were moderated by motivational differences.
The microgravity phases of parabolic flights were used to perform experiments with soap films trapped in wire frames, a variation of the wire frame experiments originally designed by the nineteenth century Belgian scientist Joseph Plateau. We considered the formation of an eightfold vertex of Plateau borders within a cubic frame.In terrestrial experiments such a vertex can only be formed when liquid is forced through the Plateau borders, but in microgravity we found this vertex to be stable under equilibrium (non-flow) conditions once the liquid volume fraction exceeds 0.022±0.005. This is consistent with the theoretical value for the transition, which for our experiment we estimate to be 0.0192.
Background13 000 cases of skin cancer are diagnosed annually in Ireland, with ultraviolet (UV) radiation exposure the strongest risk factor. Public health primary prevention campaigns focus on encouraging safe sun protective measures and skin cancer awareness. We designed a novel, digitally‐animated hospital‐based campaign targeting all aspects of sun‐protective behaviour.ObjectivesTo explore the sun‐protective attitudes and behaviours of healthcare workers, and the effect of a digital hospital‐based campaign on these findings.MethodsThis was a cross‐sectional prospective observational study involving hospital staff across the six hospitals that form the University of Limerick Hospital Group (ULHG). A two‐phase online survey, the first taking place before campaign launch, and the second upon campaign completion. The digital campaign was displayed across all hospital sites from June to September 2021. Surveys comprised questions on sun‐related attitudes and behaviours, including the internationally validated Sun Exposure Protection Index (SEPI) questionnaire.ResultsEight hundred fifty‐seven staff members completed survey 1 and 704 completed survey 2; 90% in each were female; 79% were aged 25–54; 71% reported skin types I–III. Best sun‐protective habits pre‐campaign included sunscreen use and avoiding sunburn, while wearing hats, protective clothing and seeking shade were least adopted. For 177 matched participants, there were small improvements in SEPI scores. SEPI Part 1 scores, reflecting improved risk behaviour, pre‐campaign had a median of 11 (IQR 7), and 11 (IQR 6) post campaign. SEPI Part 2 scores, reflecting readiness to adopt sun‐protective behaviours, improved from median 7 (IQR 8) to 6 (IQR 6). Post‐campaign, small improvements were seen across some individual sun‐protective behaviours and attitudes, particularly reducing time spent in the midday sun and on sun‐seeking holidays, and improved readiness to seek shade and reduce sunbathing; 79% of all respondents post‐campaign (n = 556) reported raised skin cancer awareness, and 65% (n = 458) said it influenced them to discuss sun protection with others.ConclusionsPositive improvements in attitudes and behaviours related to sun protection were seen following the digital campaign in this population of healthcare workers. These improvements along with increased willingness to discuss sun protection with others, including patients, has the potential to further benefit wider society, and supports future digital health promotion initiatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
