 DESCRIPTION (provided by applicant): Injection drug users (IDUs) are at high risk of acquiring hepatitis C virus (HCV) infection, and co-infection with human immunodeficiency virus (HIV) and HCV is highly prevalent among this population. Yet few are evaluated and treated for HCV. Low levels of awareness and knowledge about HCV represent a significant challenge to prevention and treatment among IDUs. HCV education is associated with increased disease- specific knowledge, interest in and willingness to accept treatment, and increased liver clinic attendance. The Internet offers the opportunity to deliver HCV prevention and treatment information to IDUs in a convenient and timely fashion. However, little data is available about the use and impact of Internet and mobile phone-based interventions to disseminate health interventions for IDUs. This study will conduct a formative evaluation and will design and evaluate the feasibility and acceptability of a theory-guided mobile website to disseminate HCV and HIV health information. The website is intended to complement drug abuse treatment services by offering educational support services including information about HCV and HIV, incorporating a personal HCV risk assessment, and integrating a search feature to enable users to locate HCV and HIV health care providers. Increasing knowledge and awareness of HCV among at-risk populations is consistent with the national strategy for prevention and control of HCV. Aims for the first phase (N = 200) are: (1) To characterize access to and the use of mobile phone technology and Internet activity among methadone maintenance treatment (MMT) patients; (2) To measure attitudes regarding the use of digital modalities (text messaging, e-mail, and Internet) to receive health information including HCV and HIV prevention, testing, and treatment information among MMT patients; and (3) To identify predictors of access to and the use of mobile technology and the Internet for health or medical purposes among MMT patients. Based on results obtained in the first phase, the aims for the second phase are: (1) To design and refine a mobile optimized website for the dissemination of HCV and HIV prevention, testing, and treatment information with input from digital technology experts and feedback from MMT patients; and (2) To conduct a randomized pilot study to determine whether tailored motivational text messages will increase the use of the mobile website among MMT patients. We will randomly assign 40 MMT patients who own a mobile phone to one of two conditions: 1) tailored motivational text messages; or 2) no text messages. Assessments will occur at study entry and 30 days post-randomization. We hypothesize that participants randomized to the tailored motivational text message condition will have significantly increased knowledge of HCV, a higher frequency of repeat visits to the website, and will be more likely to complete a personal HCV risk assessment survey and to be tested for HCV at the 30-day follow up than those who do not receive tailored motivational text messages. If feasible and acceptable, the website will provide reliable, efficient, and high-quality HCV health information targeting drug users with the potential for wide dissemination.

 描述（由申请人提供）：注射吸毒者（IDUs）感染丙型肝炎病毒（HCV）的风险很高，在这一人群中，人类免疫缺陷病毒（HIV）和HCV合并感染非常普遍。然而，很少有人对HCV进行评估和治疗。对丙型肝炎病毒的认识和知识水平低是注射吸毒者预防和治疗的一个重大挑战。HCV教育与增加疾病特异性知识、接受治疗的兴趣和意愿以及增加肝脏诊所就诊率相关。互联网提供了以方便和及时的方式向注射吸毒者提供HCV预防和治疗信息的机会。然而，关于使用互联网和移动的电话干预措施传播注射吸毒者保健干预措施及其影响的数据很少。本研究将进行形成性评价，并将设计和评价理论指导的移动的网站传播HCV和HIV健康信息的可行性和可接受性。该网站旨在通过提供教育支助服务补充药物滥用治疗服务，包括关于丙型肝炎病毒和艾滋病毒的信息，纳入个人丙型肝炎病毒风险评估，并整合搜索功能，使用户能够找到丙型肝炎病毒和艾滋病毒保健提供者。提高高危人群对HCV的认识和认识符合预防和控制HCV的国家战略。第一阶段（N = 200）的目的是：（1）描述美沙酮维持治疗（MMT）患者获得和使用移动的电话技术和互联网活动的特征;（2）测量对使用数字模式的态度（短信、电子邮件和互联网）接收健康信息，包括MMT患者中的HCV和HIV预防、检测和治疗信息;以及（3）确定MMT患者为健康或医疗目的而访问和使用移动的技术和互联网的预测因素。根据第一阶段的结果，第二阶段的目标是：（1）设计和完善一个移动的优化网站，用于传播HCV和HIV预防、检测和治疗信息，并听取数字技术专家的意见和MMT患者的反馈;以及（2）进行随机试验研究，以确定定制的激励性短信是否会增加MMT患者对移动的网站的使用。我们将40名拥有移动的手机的MMT患者随机分配到两种情况之一：1）定制的激励短信;或2）没有短信。将在研究入组时和随机化后30天进行评估。我们假设，随机分配到定制的激励短信条件的参与者将有显着增加的HCV知识，重复访问网站的频率更高，更有可能完成个人HCV风险评估调查，并在30天的随访中进行HCV检测，而不是那些没有收到定制的激励短信。如果可行和可接受的话，该网站将提供可靠、有效和高质量的针对吸毒者的HCV健康信息，并有可能广泛传播。
