Mobile health (mHealth) interventions show potential to broaden the reach of efficacious alcohol brief motivational interventions (BMIs). However, efficacy is mixed and may be limited by low participant attention and engagement. The present study examined the feasibility, acceptability, and preliminary efficacy of a live text-message delivered BMI in a pilot randomized clinical trial.
Participants were 66 college students (63.6% women; 61.9% White; = 19.95, = 1.66) reporting an average of 11.88 ( = 8.74) drinks per week, 4.42 ( = 3.59) heavy drinking episodes (HDEs), and 8.44 ( = 5.62) alcohol-related problems in the past month. Participants were randomized to receive either (a) education or (b) an alcohol BMI plus behavioral economic substance-free activity session (SFAS), each followed by 4 weeks of mini sessions. All sessions were administered via live text-message. Participants completed assessments postintervention (after the 4th mini session) and at 3-month follow-up.
90.9% completed both initial full-length sessions and at least two of the four mini sessions with 87.9% retention at 3-month follow-up. Participants found the interventions useful, interesting, relevant, and effective, with no between-group differences. There were no statistically significant group differences in drinks per week or alcohol-related problems at follow-up, but BMI + SFAS participants reported fewer past-month HDEs than those who received education.
Live text-messaging to deliver the BMI + SFAS is feasible and well-received. The preliminary efficacy results should be interpreted cautiously due to the small sample size but support further investigation. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
移动健康（mHealth）干预措施显示出扩大有效简短动机干预（BMI）覆盖面的潜力。然而，其效果参差不齐，可能受到参与者关注度和参与度低的限制。本研究在一项试点随机临床试验中，考察了实时短信传递 BMI 的可行性、可接受性和初步效果。
共有 66 名大学生参与了研究（63.6%为女性；61.9%为白人； = 19.95， = 1.66），他们平均每周饮酒 11.88 次（ = 8.74），有 4.42 次重度饮酒事件（HDEs）（ = 3.59），过去一个月有 8.44 次（ = 5.62）与酒精相关的问题。参与者被随机分配接受（a）教育或（b）酒精 BMI 加行为经济学无物质活动课程（SFAS），每个干预都有 4 周的迷你课程。所有课程都通过实时短信进行管理。参与者在干预后（第 4 个迷你课程后）和 3 个月随访时完成评估。
90.9%的参与者完成了完整的长课程和至少两个迷你课程，其中 87.9%在 3 个月随访时保持了参与度。参与者认为干预措施有用、有趣、相关且有效，两组之间没有差异。在随访时，两组之间每周饮酒量或与酒精相关的问题均无统计学显著差异，但接受 BMI+SFAS 的参与者报告的过去一个月 HDE 次数少于接受教育的参与者。
实时短信传递 BMI+SFAS 是可行且受欢迎的。由于样本量小，初步效果结果应谨慎解释，但支持进一步研究。
