背景:年轻人的行为使他们有患皮肤癌的风险。通过社交媒体传播数字健康促进干预措施是一种潜在的有前途的策略,可以通过增加紫外线辐射(UVR)保护和皮肤癌检查来改变皮肤癌风险行为。
目的:本研究旨在比较3种旨在改变紫外线照射的数字干预措施,防晒,和皮肤癌检测行为在中高危人群中。
方法:本研究是2种积极干预措施的混合II型有效性实施随机对照试验,数字皮肤癌风险降低干预措施(UV4。我[基本])与增强版本(UV4。me2[增强]),和一本电子小册子(e-pamphlet)。在一年的时间里,对主要通过Facebook和Instagram招募的1369名美国年轻人进行了干预效果评估。鼓励干预参与和行为改变的增强措施包括更全面的目标设定活动,与先前建立的调解员相关的持续主动消息传递(例如,自我效能)的UVR暴露和保护,模块完成的嵌入式激励措施,以及正在进行的新闻和视频更新。通过线性回归评估的主要结果效果是UVR暴露和防晒和防护习惯。通过逻辑回归评估的次要结果效果是皮肤自我检查,医生皮肤检查,防晒霜的使用,室内鞣制,还有晒伤.
结果:与电子小册子相比,积极干预措施增加了防晒(基本:P=.02;增强:P<.001)和习惯性防晒(基本:P=.04;增强P=.01)。增强的干预比基本的干预增加了更多的防晒。每次主动干预在3个月的随访中增加了防晒霜的使用(基本:P=.03;增强:P=.01),并在1年时进行皮肤自我检查(基本:P=.04;增强:P=.004),与电子小册子相比。其他干预效果以及基本干预效果和增强干预效果之间的差异不显着。
结论:积极干预措施可有效改善多种皮肤癌风险和皮肤癌预防行为。与基础干预相比,加强干预增加了防晒的改善,但没有其他行为。未来的分析将探索干预参与(例如,审查内容的比例)。

BACKGROUND: Young adults engage in behaviors that place them at risk for
skin cancer. Dissemination of digital health promotion interventions via social media is a potentially promising strategy to modify skin cancer risk behaviors by increasing UV radiation (UVR) protection and skin cancer examinations.
OBJECTIVE: This
study aimed to compare 3 digital interventions designed to modify UVR exposure, sun protection, and skin cancer detection behaviors among young adults at moderate to high risk of
skin cancer.
METHODS: This
study was a hybrid type II effectiveness-implementation randomized controlled
trial of 2 active interventions, a digital
skin cancer risk reduction intervention (UV4.me [basic]) compared with an enhanced version (UV4.me2 [enhanced]), and an electronic pamphlet (e-pamphlet). Intervention effects were assessed over the course of a year among 1369 US young adults recruited primarily via Facebook and Instagram. Enhancements to encourage intervention engagement and behavior change included more comprehensive goal-setting activities, ongoing proactive messaging related to previously established mediators (eg, self-efficacy) of UVR exposure and protection, embedded incentives for module completion, and ongoing news and video updates. Primary outcome effects assessed via linear regression were UVR exposure and sun protection and protection habits. Secondary outcome effects assessed via logistic regression were
skin self-exams, physician
skin exams, sunscreen use, indoor tanning, and sunburn.
RESULTS: The active interventions increased sun protection (basic: P=.02; enhanced: P<.001) and habitual sun protection (basic: P=.04; enhanced P=.01) compared with the e-pamphlet. The enhanced intervention increased sun protection more than the basic one. Each active intervention increased sunscreen use at the 3-month follow-up (basic: P=.03; enhanced: P=.01) and skin self-exam at 1 year (basic: P=.04; enhanced: P=.004), compared with the e-pamphlet. Other intervention effects and differences between the Basic and Enhanced Intervention effects were nonsignificant.
CONCLUSIONS: The active interventions were effective in improving several skin cancer risk and skin cancer prevention behaviors. Compared with the basic intervention, the enhanced intervention added to the improvement in sun protection but not other behaviors. Future analyses will explore intervention engagement (eg, proportion of content reviewed).
