The goal of this clinical trial is to learn if the eTSF intervention is feasible among Latinx young adults with alcohol use disorder. The main questions it aims to answer are: * Is eTSF feasible? * Is eTSF effective in reducing alcohol use and increasing 12-step engagement compared to the control condition? The control condition will receive educational materials on drinking problems and a list of local/online AA meetings Participants will * Be randomly assigned to either the eTSF condition or the control condition. * Fill out the baseline online survey. * Go through the eTSF app/control materials. * And at 3 months post-baseline, fill out the follow-up online survey.

eTSF is a smartphone app intervention featuring culturally relevant content aimed at supporting Latinx young adults with alcohol use disorder in participating in 12-step groups.
Educational materials on drinking problems and a list of local/online AA meetings.
Recruitment feasibility
Recruitment feasibility will be measured by the number of participants screened and enrolled each month.
Time frame: Every 4 weeks up to 2 years
Randomization feasibility
Randomization feasibility will be measured by the number of baseline demographic variables with statistically significant group differences.
Time frame: From recruitment to baseline assessment up to two years
Retention/attrition feasibility
Retention/attrition feasibility will be measured by retention rates in each condition.
Time frame: From recruitment to the end of the trial at three months.
Adherence feasibility
Adherence feasibility will be measured by the percentage of eTSF app components used by the eTSF condition participants.
Time frame: From recruitment to the end of the trial at three months.
Assessment feasibility
Assessment feasibility will be measured by the proportion of missing data in each assessment.
Time frame: From recruitment to the end of the trial at three months.
Intervention credibility
Intervention credibility will be measured using a single-item question: "On a scale from 1 to 5, where 1 indicates 'not at all' and 5 indicates 'very much,' to what extent do you believe this treatment will be beneficial for you?" Only eTSF condition participants will receive this measure.
Time frame: From baseline to the end of treatment at three months.
Intervention satisfaction
Intervention satisfaction will be measured using the mHealth Satisfaction Questionnaire, which has a total score range from 14 to 42. Higher total scores indicate greater user satisfaction with the mHealth app.
Time frame: From baseline to the end of treatment at three months.
Intervention acceptability
Acceptability will be measured using the Abbreviated Acceptability Rating Profile, which scores range from 8 to 48. Higher scores indicate greater acceptability of the intervention.
Time frame: From baseline to the end of treatment at three months.
Intervention engagement
Intervention engagement will be automatically recorded by the app during the study period and be measured in terms of app opening frequency, time spent on the app per use session (i.e., the time between opening and closing the app), most frequently used intervention component, time spent per intervention component, the completion rate of each selected component, reports of technical problems.
Time frame: From baseline to the end of treatment at three months.
Alcohol use
Alcohol use will be measured using the Time-Line Follow-Back (TLFB) method-Form 90, which helps participants recall and mark days on which they used alcohol during the past 90 days.
Time frame: From baseline to the end of treatment at three months.
12-Step fellowship engagement
12-Step fellowship engagement will be measured with the Multi-Dimensional Mutual-help Activity Scale (MDMAS), which measures seven dimensions of experience (meeting attendance, meeting participation, fellowship involvement, step work, mandated attendance, affiliation, and safety). Total score ranges from 32-160 with higher scores within indicating greater engagement.
Time frame: From baseline to the end of treatment at three months.
