Evaluating Change in Drinking Identity as a Mechanism for Reducing Hazardous Drinking - Study 2

The purpose of the proposed research is to evaluate whether changes in drinking identity (DI; how much one associates one's self with drinking) can reduce hazardous drinking (HD; heavy alcohol use and negative alcohol-related consequences) among current college students. The study seeks to explore whether manipulating DI among participants will have changes in self-efficacy, craving, and HD. If such an effect can be found, DI may be a mechanism for HD behavior change and will allow researchers to develop and improve interventions aimed at HD behaviors in high-risk young adults.

About this study

Experimentally manipulate DI to increase self-efficacy, decrease alcohol craving and reduce HD. We will recruit 328 student hazardous drinkers and use an expressive writing task to manipulate their DI, the salience of their social network, and their writing perspective. The last factor is included because writing in a self-distanced (3rd person) vs. self-immersed (1st person) perspective has been linked to greater cognitive control. We will evaluate the manipulation's immediate effects on DI, self-efficacy, and craving. Participants will also complete two weekly follow-up "booster" sessions. Longer-term effects on DI, self-efficacy, craving and HD will be evaluated at additional 2-week, 1-month, and 3-month follow-ups.

With the outbreak of the COVID-19 pandemic, new subject enrollment was paused between March and September 2020. In light of the continued COVID-19 pandemic, the study team made the decision to move the in-person, lab-based session (where participants completed the writing task) to online sessions as of October 2020. With the move to online sessions, we have discontinued the cue reactivity task and the accompanying craving assessment. Inclusion criteria have shifted slightly -- we now explicitly require participants to be currently living in Washington State (this criterion was implicit in our previous criteria and procedures) . The structure of the study otherwise remains the same.

Who can participate

Healthy volunteers accepted: Yes

Treatment and study plan

Narrative Writing

Behavioral

An writing task in which participants are given a description of a possible future self (that varies 3 factors: topic; drinking vs. smartphone; perspective: 1st vs. 3rd-person; and social network: specifically asked to be included vs. not specifically asked to be included). Participants are asked to imagine that future self vividly and to write about the thoughts and feeling describe themselves and their experiences, the characteristics they hope or wish they will ideally possess, the characteristics that they would need to have and the roles they will take on or things they will be doing. Participants are given 20 minutes to think and write. They will write and think about the same future on each of three lab-sessions (which occur at 1-week intervals).

    Rutgers Alcohol Problems Inventory (RAPI) will be used to assess alcohol problems; item response options range from 0 to 4; total score ranges from 0 to 100; higher scores = worse outcomes

  8. changes in last two week alcohol problems

    Time frame: assessed at lab 2 and 3 (weeks 2 and 3) and at 2 week and 1 month follow up; data will be reported through 1 month follow up

    adapted from RAPI & Young Adult Alcohol Problems Screening Test (YAAPST); item responses are 0 (did not happen) or 1 (happened); higher scores (range from 0 to 10) = worse outcomes

Secondary outcomes

  1. changes in future drinking intentions

    Time frame: assessed at lab 1, lab 2, lab 3 (weeks 1-3); data will be reported through week 3

    adapted from daily drinking questionnaire; assesses how much individuals think they will drink each day of the next week

  2. changes in frequency of heavy & extreme binge drinking

    Time frame: assessed at lab 1 (week 1) &

    frequency of heavy episodic (4/5 or more drinks for women/men on a single occasion) and extreme binge drinking (at least 8/10 drinks or at least 12/15 drinks for women/men on a single occasion); definitions are from the National Institute of Alcohol and Alcoholism

  3. Changes in Readiness to Change Drinking

    State (current) affect will be assessed immediately prior to and after the narrative writing task; two items (one assessing positive affect and one assessing negative affect); item response range from 0 to 100, with 100 indicating greater intensity of feeling; affect will be assess each time participants complete the narrative writing task (i.e. lab 1, lab 2, lab 3); no changes in affect are expected

  6. Manipulation check questions about the narrative writing task

    Time frame: will be assessed and reported for each of the 3 lab sessions (weeks 1, 2, and 3)

    Following the narrative writing task (which occurs at each of the lab session), participants will be asked 5 items about what they wrote and imagined; each item will be evaluated separately; response options range from -3 to +3; items assess how vividly they imagined what they wrote; how easy it was to imagine what they wrote; how much writing made them seem their life differently; how plausible what they imagined was; how relatable what they wrote about was; for all items higher scores = better outcomes
