NCT06191861

Brief Summary

The purpose of the proposed research is to evaluate (1) whether a future possible self task (FPST) can lead to changes drinking identity (DI; how much one associates one's self with drinking) and (2) whether the FPST and changes in drinking identity also change indicators of alcohol misuse . This study focuses on individuals who are graduating from highly school, which is a time of transition and identity change. If such changes can be demonstrated, DI may be a mechanism for alcohol misuse and the FPST may be an additional, novel intervention strategy to reduce alcohol misuse during the post-high school transition. The goal of this clinical trial is to test the future possible self task (FPST) in individuals who are about to graduate from high school. The main questions it aims to answer are:

  • Can the FPST change drinking identity (a risk factor for alcohol misuse)?
  • Can the FPST reduce risks for alcohol misuse? Participants will complete the FPST, a task that involves writing for 20 minutes, and will answer a series of questionnaires and computer-based word categorization tasks. Participants will be followed for a year after completing the FPST. Researchers will compare different versions of the FPST and different doses (one writing sessions vs. 3 writing sessions) to see which are more effective for changing drinking identity and reducing risks for alcohol misuse.

Outcome Measures

Primary Outcomes (6)

  • Explicit drinking identity

    This is will be evaluated by the Alcohol Self-Concept Scale. A mean score will be calculated. Scores range from -3 to +3. Higher scores indicate stronger alcohol self-concept

    Will be assessed at baseline, post-intervention, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Implicit drinking identity

    This is will be evaluated by the Drinking Identity Implicit Association Test (IAT). A summary score, called a D score, which is similar to a Cohen's d effect size, will be calculated. Scores range from -2 to +2; higher scores indicate stronger implicit drinking identity.

    Will be assessed at baseline,post-intervention, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Drinks per week

    This is will be evaluated by the Daily Drinking Questionnaire (DDQ). It assesses drinks consumed each day of the week during a typical week during the last month. A sum of drinks over the course of the week will be calculated.

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Peak drinks per month

    This is will be evaluated by the Quantity/Frequency Measure (Q/F). It includes an assessment of the number of drinks consumed when one drank the most during the last month.

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Typical drinks per occasion

    This is will be evaluated by the Quantity/Frequency Measure (Q/F). It includes an assessment of the number of drinks consumed on a typical drinking occasion during the last month.

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Alcohol-related problems

    This is will be evaluated by the Brief Young Adult Alcohol Consequences Questionnaire. It assesses the consequences of drinking (happened yes or no) that occurred during the last month. A sum will be calculated. Higher scores indicate more experiencing more negative consequences from drinking. Scores range from 0 to 24

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

Secondary Outcomes (9)

  • Risk of Alcohol Use Disorder

    Will be assessed at baseline and at 12-month follow-up

  • Alcohol Craving - Momentary

    Will be assessed at baseline and 2 weeks after baseline

  • Alcohol Craving - Retrospective

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Alcohol Expectancies

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • Drinking Motives

    Will be assessed at baseline, 1-month follow up, 3-month follow up, 6 month-follow up, & 12-month follow up

  • +4 more secondary outcomes
