简要总结
This study aims to examine the feasibility and acceptability of a mobile health intervention to reduce alcohol use and related consequences among young adults. Participants will be randomly assigned to either receive access to the mobile health intervention or receive only generic study surveys. Participants will receive text message surveys sent to their personal cellphone for 4 weeks per their assigned trial arm. All participants will receive a post-survey 30 days after their final weekly survey text.
详细描述
This study aims to determine whether a mobile health intervention to reduce alcohol use and related consequences is acceptable and feasible among young adults who engage in high-intensity drinking (HID; 8+/10+ drinks per drinking occasion for females/males, respectively). The investigators aim to recruit 40 adults between 18-25 years of age who report at least one HID episode in the past 30 days.
After providing informed consent, participants will be randomly assigned to receive the mobile health intervention or control surveys only.
Participants will attend one online study visit to enroll in the study and be assigned to their study arm. All subsequent study activities will be completed asynchronously. Participants will then receive text message prompts and/or surveys to their personal cellphone either Wednesday or Thursday through Sunday for four consecutive weeks. Participants will receive a post-test survey 30 days after their final weekly survey.

研究组 & 干预措施
Mobile Health Intervention
Participants will receive access to the mobile health intervention. This includes access to an online dashboard which includes a drink counter, ability to track the number of drinks consumed over the course of the study, ability to set drinking-related goals for oneself, and alcohol-related resources. Participants in the intervention will also receive tailored messages during drinking episodes which target contextual factors to reduce alcohol use.
干预措施: Mobile Health Intervention to Reduce Alcohol Use Among Young Adults (Behavioral)
No-contact control
Participants will receive only morning surveys and the 30-day post-test survey.
结局指标
主要结局
Average Satisfaction with the Intervention
时间窗: Assessed 30 days after the last 4-week survey text.
Measured using the following item, "How satisfied are you with your experience using this intervention?" with a 5-point response scale ranging from Not at All Satisfied (1) to Extremely Satisfied (5). A higher score indicates higher satisfaction with the intervention
Average Engagement with the Intervention Measured by the DCBI Scale
时间窗: Assessed 30 days after the last 4-week survey text.
Engagement will be assessed via 8 items from the Digital Behavior Change Intervention (DCBI) Scale. The item stem "How strongly did you experience the following?" will be repeated for the following concepts: interest, intrigue, focus, inattention, distraction, enjoyment, annoyance, and pleasure. All items will be scored on a 7 point scale from Not at All (1) to Extremely (7) and an average composite score will be derived for each participant based on responses across the seven items. Scores range from 1-7, where a higher score indicates higher engagement with the intervention.
次要结局
- Number of Drinks Consumed per Drinking Episode(Four days per week (Thursday-Sunday) for four consecutive weeks (16 total times).)
- Number of Drinks Consumed per Drinking Episode(Four days per week (Thursday-Sunday) for four consecutive weeks (16 total times).)
- Average Drinking Level per Drinking Episode(Four days per week (Thursday-Sunday) for four consecutive weeks (16 total times).)
- Frequency Score of Alcohol-Related Consequences Measured by BYAACQ(Assessed 30 days after the last 4-week survey text.)
