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.
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.
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.
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.
本试验旨在研究通过短信发送至无线手持电脑的个性化干预措施，以减少大学生酒精相关后果的可行性和短期效果。
40名大学生被随机分配到两个研究组之一。在对照组中，参与者使用手持电脑完成关于他们饮酒行为及相关变量的每日调查。在治疗组中，参与者使用手持电脑完成每日调查并接收关于饮酒单位的个性化信息。这些个性化信息涉及饮酒的后果，并根据受访者报告的行为、自我效能感以及对酒精相关后果的结果预期进行定制。
所有治疗组参与者均报告在其手持电脑上收到了信息；大多数学生在12 - 14天内收到了信息。在控制基线差异后，治疗组参与者在研究期间报告的每次饮酒日饮酒量显著少于对照组参与者。在随访时，治疗组参与者因饮酒而陷入麻烦的预期低于对照组参与者。参与者对这些信息提供了正面和负面的反馈。
本研究证明了通过无线手持电脑发送个性化信息的可行性。通过手持电脑发送的关于避免饮酒负面后果的个性化信息对与酒精相关的态度和行为产生了虽小但积极的影响。未来的研究应以更大、更多样化的样本，在更长时间内，并针对其他受众来重复这些发现。
