目的：这项试验的目的是调查通过向无线手持计算机发送短信的量身定制干预措施的可行性和短期结果，以减少大学生中与酒精相关的后果。方法：将40名大学生随机分为两组。在控制组，参与者使用掌上电脑完成关于他们饮酒行为和相关变量的日常调查。在治疗组中，参与者使用手持电脑完成日常调查，并接收关于这些单位的个性化信息。这些量身定做的信息针对酒精使用的后果，并根据受访者报告的行为、自我效能和对酒精相关后果的结果预期而量身定做。结果：所有治疗组参与者都报告在他们的掌上电脑上收到消息；大多数学生在12-14天收到消息。在控制基线差异的情况下，在研究期间，治疗组的参与者报告说，每天饮酒的量明显少于对照组的参与者。在随访中，与对照组参与者相比，治疗组的参与者对他们因饮酒而陷入麻烦的预期更低。参与者对这些信息提供了积极和消极的反馈。结论：这项研究证明了通过无线手持计算机传递定制消息的可行性。通过掌上电脑发送的关于避免饮酒负面后果的定制信息对与酒精相关的态度和行为产生了微小但积极的影响。未来的研究应该通过更大、更多样化的样本、在更长的时间内以及在其他受众中重复这些发现。
Objective: The purpose of this trial was to investigate the feasibility and short-term outcomes of a tailored intervention, delivered via text messages to wireless handheld computers, to reduce alcohol-related consequences among college students. Method: Forty college students were randomly assigned to one of two study groups. In the control group, participants used handheld computers to complete daily surveys about their drinking behavior and related variables. In the treatment group, participants used the handheld computers to complete daily surveys and to receive individually tailored messages on the units. The tailored messages addressed consequences of alcohol use and were tailored to respondents' reported behavior, self-efficacy, and outcome expectancies regarding alcohol-related consequences. Results: All treatment group participants reported receiving messages on their handheld computers; most students were sent messages on 12-14 days. Controlling for baseline differences, participants in the treatment group reported drinking significantly fewer drinks per drinking day than participants in the control group during the study period. At follow-up, participants in the treatment group had lower expectancies that they would get in trouble as a result of alcohol consumption than did control group participants. Participants provided both positive and negative feedback about the messages. Conclusions: This study demonstrated the feasibility of delivering tailored messages via wireless handheld computers. Tailored messages about avoiding negative consequences of alcohol use delivered via handheld computers had small but positive effects on alcohol-related attitudes and behaviors. Future research should replicate these findings with a larger, more diverse sample, during a longer period, and with other audiences.
