Most users of electronic cigarettes (e-cigarettes) report initiating use to quit combustible cigarettes. Nevertheless, high levels of dual use (i.e., using both combustible cigarettes and e-cigarettes) occur among adults. Using formative data from in-depth interviews and employing learner verification, we adapted an existing, validated self-help smoking-cessation intervention (Stop Smoking for Good; SSFG) to create a targeted intervention for dual users, If You Vape: A Guide to Quitting Smoking (IYV). In Phase I, in-depth interviews (n = 28) were conducted to assess relevance of the existing SSFG materials (10 booklets, nine pamphlets) and identify new content for the booklets. Next, for Phase II, learner verification interviews (n = 20 dual users) were conducted to assess their appeal and acceptability. Several key themes emerged from the Phase I in-depth interviews. Findings led to the inclusion of e-cigarette-specific strategies used by successful quitters such as gradually reducing nicotine levels, switching from tobacco flavor to alternative flavors, and limiting e-cigarette use to places one would normally smoke (i.e., not expanding use). Suggestions from Phase II learner verification included broadening the visual appeal for a younger, more diverse demographic, expanding tips for quitting smoking via e-cigarettes, and expanding terminology for e-cigarette devices. Beginning with an efficacious self-help intervention, we used a systematic process to develop a version specifically for dual users.

烟草卷烟和电子烟双重使用者自助戒烟干预措施的开发

大多数电子烟（电子烟）用户报告说，他们开始使用它来退出可燃香烟。然而，成年人中仍存在大量的双重用途（即同时使用可燃香烟和电子烟）。利用深入访谈中的形成性数据并通过学习者验证，我们采用了一种经过验证的现有自助戒烟干预措施（永远戒烟； SSFG），为双重使用者创建有针对性的干预措施。戒烟（IYV）。在第一阶段，进行了深入访谈（n = 28），以评估现有SSFG材料（10本小册子，9本小册子）的相关性，并确定这些小册子的新内容。接下来，对于第二阶段，学习者验证面试（n= 20位双重用户）进行了评估，以评估他们的吸引力和可接受性。在第一阶段的深度访谈中出现了几个关键主题。这些发现导致成功戒烟者采用了特定于电子烟的策略，例如逐渐降低尼古丁含量，从烟草香精转向其他香精，以及将电子烟的使用限制在通常会吸烟的地方（即，不扩大使用范围） 。来自第二阶段学习者验证的建议包括扩大年轻人口的视觉吸引力，扩大通过电子烟戒烟的技巧，以及扩展电子烟设备的术语。从有效的自助干预开始，我们使用了系统的过程来开发专门针对双重用户的版本。
