Recent trial results show that an interactive short message service (SMS) text message intervention, Texting to Reduce Alcohol Consumption (TRAC), is effective in reducing heavy drinking in non-treatment-seeking young adults, but may not be optimized.
To assess the usability of the TRAC intervention among young adults in an effort to optimize future intervention design.
We conducted five focus groups with 18 young adults, aged 18-25 years, who had a history of heavy drinking and had been randomized to 12 weeks of the TRAC intervention as part of a clinical trial. A trained moderator followed a semistructured interview guide. Focus groups were audiotaped, transcribed, and analyzed to identify themes.
We identified four themes regarding user experiences with the TRAC intervention: (1) ease of use, (2) comfort and confidentiality, (3) increased awareness of drinking behavior, and (4) accountability for drinking behavior. Participants' comments supported the existing features of the TRAC intervention, as well as the addition of other features to increase personalization and continuing engagement with the intervention.
Young adults perceived the TRAC intervention as a useful way to help them reduce heavy drinking on weekends. Components that promote ease of use, ensure confidentiality, increase awareness of alcohol consumption, and increase accountability were seen as important.
最近的试验结果表明，互动式短消息服务（SMS）短信干预措施“Texting to Reduce Alcohol Consumption（TRAC）”可有效减少非治疗寻求的年轻成年人的重度饮酒，但可能还需要进一步优化。
评估 TRAC 干预措施在年轻成年人中的可用性，以优化未来的干预设计。
我们对 18 名年龄在 18-25 岁之间、有重度饮酒史且被随机分配到 TRAC 干预措施 12 周的年轻成年人进行了 5 次焦点小组讨论。一名经过培训的主持人遵循半结构化访谈指南进行讨论。对焦点小组进行了录音、转录和分析，以确定主题。
我们确定了四个与 TRAC 干预措施用户体验相关的主题：（1）易用性，（2）舒适度和保密性，（3）提高对饮酒行为的认识，（4）对饮酒行为的问责制。参与者的评论支持了 TRAC 干预措施的现有功能，以及增加其他功能以增加个性化和继续参与干预的功能。
年轻人认为 TRAC 干预措施是一种帮助他们减少周末重度饮酒的有用方法。促进易用性、确保保密性、提高对饮酒行为的认识以及增加问责制的组件被认为是重要的。
