背景：16-24岁的年轻人不成比例地受到性传播感染(STI)的影响。性传播感染可能会对受影响的个人造成严重的健康后果，据估计，国民卫生服务每年的治疗费用为6.2亿美元。因此，英国政府已将降低这一群体中的性传播感染比率作为优先事项。当年轻人通过互联网获得性病自我采样试剂盒时，错过了增加避孕套使用的机会。目的：我们的目标是开发一种基于理论的量身定制的干预措施，以增加16-24岁访问衣原体自我采样网站的人的避孕套使用量。方法：该干预措施是使用干预地图开发的，并与年轻人共同设计。实施了以下步骤：(1)利用计算机和数字干预确定避孕套使用的重要决定因素及其可变性的证据；(2)设定干预目标、性能目标和改变目标；(3)确定针对这些决定因素的行为改变原则(BCP)和实用策略；(4)开发能够提供BCP和实用策略的干预材料。结果：现有衣原体自我采样网站的用户在订购采样试剂盒后被签到WRIPT。每个用户都确定了使用避孕套的显著障碍，并针对这些障碍分配了相关的干预措施。内容包括：(1)避孕套样品盒，(2)在线避孕套分发服务，(3)避孕套携带产品，(4)避孕套演示视频，(5)一系列关于避孕套使用的交流视频，(6)真实夫妇讨论和示范使用避孕套的性爱视频。结论：此次干预将针对因检测状况而特别容易接受信息和支持改变行为的年轻人。
BACKGROUND: Young people aged 16-24 years are disproportionately affected by sexually transmitted infections (STIs). STIs can have serious health consequences for affected individuals and the estimated annual cost of treatment to the National Health Service is 620 million. Accordingly, the UK government has made reducing the rates of STIs among this group a priority. A missed opportunity to intervene to increase condom use is when young people obtain self-sampling kits for STIs via the internet.OBJECTIVE: Our aim was to develop a theory-based tailored intervention to increase condom use for 16-24-years-olds accessing chlamydia self-sampling websites.METHODS: The intervention, Wrapped, was developed using Intervention Mapping and was co-designed with young people. The following steps were performed: (1) identification of important determinants of condom use and evidence of their changeability using computer and digital interventions; (2) setting the intervention goal, performance objectives, and change objectives; (3) identification of Behavior Change Principles (BCPs) and practical strategies to target these determinants; and (4) development of intervention materials able to deliver the BCPs and practical strategies.RESULTS: Users of existing chlamydia self-sampling websites are signposted to Wrapped after placing an order for a sampling kit. Salient barriers to condom use are identified by each user and relevant intervention components are allocated to target these. The components include the following: (1) a sample box of condoms, (2) an online condom distribution service, (3) a product for carrying condoms, (4) a condom demonstration video, (5) a series of videos on communication about condom use, and (6) erotic films of real couples discussing and demonstrating condom use.CONCLUSIONS: This intervention will be directed at young people who may be particularly receptive to messages and support for behavior change due to their testing status.
