Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Tailoring intervention approaches to students at various levels of risk, including abstainers or lighter drinkers, may greatly increase efficacy and reduce costs associated with universal interventions (King et al., 2008). No single intervention is likely to sufficiently reduce college drinking or consequences; therefore a "mix of strategies is best". An underexplored strategy is delivering intervention content that reinforces existing reasons for not drinking among abstainers and lighter drinkers, with the goal of delaying the initiation of heavy drinking and/or the escalation to heavy drinking during the first year of college. Given that longitudinal findings indicate that stronger endorsement of reasons for drinking lightly or not drinking, such as academic responsibilities, normative influence, and concern for social images are associated with delayed alcohol initiation, lower levels of alcohol use and higher rates of abstention among young adults, including college students, interventions for abstainers and lighter drinkers that focus on reinforcing proximal reasons not to drink or to drink lightly have promise to dissuade students from initiation of drinking or to delay more hazardous drinking patterns later on.
Additionally, mobile phone-based interventions are an innovative method for reaching young people and have been established as an evidence-based, recommended approach towards addressing health issues including alcohol use. Mobile phone text-messaging (TM) offers an innovative technological approach to brief intervention for college students in a mode in which they are familiar and they already use frequently. Presenting preventative intervention content via TM, especially for abstainer and lighter drinking college students, may be one way to delay alcohol use initiation and prevent the escalation of alcohol use during the first year of college. Therefore, the present project has the following primary aims:
Aim 1: Recruit first year college students who are abstainers and lighter drinkers to examine students' reactions to TM intervention content through an iterative process of focus groups, intervention content development, and user feedback, which will inform a new intervention to be delivered in a pilot study (Aim 3).
Aim 2: Through focus groups, elicit responses to timing of the TM intervention, specifically what days and times per week and how many times per day (set within research-established ranges) abstainer and lighter drinkers think receiving TMs will the most useful and impactful to inform TM delivery for the pilot study (Aim 3).
Aim 3: Conduct a pilot study with 6 weeks of TM intervention content, a 6 week post-intervention assessment and 3, 6, and 9 month follow-ups among 100 abstainer or lighter drinking first-year college students to determine feasibility, acceptability, and preliminary effect sizes (to estimate power and sample sizes for a future R01). Newly enrolled first-year college students will be randomized to the TM intervention or assessment only control. The investigators hypothesize the TM Intervention will be feasible and acceptable to abstainer and lighter drinking students, including being accessible, usable, convenient, relevant and helpful. The investigators further hypothesize that receiving the TM intervention will be associated with less initiation and escalation of drinking, fewer negative consequences, more favorable prototypes of abstainers and lighter drinkers, greater perceived abstaining and light drinking norms, greater engagement and enjoyment of alternative activities, and greater endorsement of personal goals that do not involve alcohol at the 6 week post-intervention assessment and 3, 6, and 9 month follow-ups relative to assessment only control.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Text Messaging Intervention Group
Participants in the Text Messaging Intervention condition will be provided a predetermined number of messages per week (based partially on responses from Phase 2 focus group) for 6 weeks delivered on Thursdays, Fridays, and Saturdays, which are the most common days of the week that heavy drinking occurs as well as other days and times that focus group participants indicated would be the most helpful.
Text Messaging Intervention
The content for the text messaging Intervention will be designed to be non-confrontational in tone, seek to increase motivation to drink lightly or not at all, and based both on general information about light and non-drinking as well as information provided during the baseline assessment.
Assessment Only Control
Participants in the assessment only control will not receive any text messages, but will complete all survey assessments on the same schedule as the Text Message Intervention Group.
No interventions assigned to this group
