Several randomized trials have found behavior change programs delivered via text messaging to be efficacious to improve preventive health behaviors such as physical activity and stopping smoking; however few have assessed its value in skin cancer prevention or early detection. The HealthyTexts study enrolled 678 participants 18-42 years, and assigned them to receive 21 text messages about skin cancer prevention, skin self-examination or physical activity (attention control) over the course of one year. Baseline data have been collected and outcomes will be assessed at three months and twelve months post-intervention. The trial aims to increase the mean overall sun protection habits index score from 2.3 to 2.7 with a standard deviation of 0.5 (effect size of 0.5) and the proportion of people who conduct a whole-body skin self-examination by an absolute 10%. This paper describes the study design and participants' baseline characteristics. In addition, participants' goals for their health, and strategies they apply to achieve those goals are summarized.
几项随机试验发现，通过短信发送的行为改变计划对于改善预防健康行为（如体育锻炼和戒烟）是有效的; 然而，很少有研究评估其在皮肤癌预防或早期检测方面的价值。HealthyTexts 研究招募了 678 名 18-42 岁的参与者，并将他们分为三组：接受 21 条关于皮肤癌预防、皮肤自我检查或体育活动（对照）的短信，为期一年。已收集基线数据，并在干预后三个月和十二个月评估结果。该试验旨在将平均整体防晒习惯指数评分从 2.3 提高到 2.7，标准差为 0.5（效果大小为 0.5），并使进行全身皮肤自我检查的人数增加绝对值 10%。本文介绍了研究设计和参与者的基线特征。此外，还总结了参与者对健康的目标以及他们为实现这些目标而采用的策略。
