Brief summary

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.

Detailed description

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.

Interventions

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).

Masking description

The PI, the project coordinator, and experimenters will not know which participants have been assigned to each condition. Outcomes are assessed via computer/online survey. There is no human outcome assessor in this study.

Intervention model description

Participants are randomly assigned to a condition to receive one of eight writing prompt variants in a 2x2x2 study design. There is also a within subjects component as participants complete the same writing prompt 3 times (once per week over a 3-week period).

Design outcomes

Primary

MeasureTime frameDescription
changes in self-efficacywill be assessed at lab 1, lab 2, lab 2 (weeks 1-3) & long-term follow up (2-week, 1 month, 3 month); data will be reported through study completion (3 month follow up)drinking refusal self-efficacy questionnaire
Changes in Explicit Drinking identitywill be assessed at lab 1, lab 2, lab 2 (weeks 1-3) & long-term follow up (2-week, 1 month, 3 month); data will be reported through study completion (3 month follow up)Alcohol Self-concept Scale; item responses range from -3 to +3; average score on all items is calculated; lower scores represent a better outcome
Changes in Implicit Drinking identitywill be assessed at lab 1, lab 2, lab 2 (weeks 1-3) & long-term follow up (2-week, 1 month, 3 month); data will be reported through study completion (3 month follow up)drinking identity implicit association test (IAT)
changes in last two week alcohol problemsassessed 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 upadapted 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
changes in last 3 month alcohol problemsAssessed at lab 1 (week1) and 3-month follow up; data will be reported through study completion (3 month follow up)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
changes in alcohol consumptionwill be assessed at lab 1, lab 2, lab 2 (weeks 1-3) & long-term follow up (2-week, 1 month, 3 month); data will be reported through study completion (3 month follow up)Modified timeline follow back will assess past daily alcohol consumption (# standard drinks per day); higher consumption = worse outcomes
changes in past week cravingwill be assessed at lab 1, lab 2, lab 2 (weeks 1-3) & long-term follow up (2-week, 1 month, 3 month); data will be reported through study completion (3 month follow up)Penn Alcohol Craving Scale; item responses range from 0 to 6; total score on all items is calculated (can range from 0 to 30); lower scores = better outcome
cue-related cravingCue related craving will be assessed following the cue reactivity task, which occurs during the third and final lab-based session (technically, the third week of the study)current craving from cue reactivity task; assessed via alcohol urge questionnaire

Secondary

MeasureTime frameDescription

Other

MeasureTime frameDescription
Manipulation check questions about the narrative writing taskwill 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
changes in affectassessed pre-post-writing during lab 1, lab 2, lab 3 (weeks 1-3); data will be reported through week 3State (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
Changes in smartphone useAssessed at lab 1 (week 1) and long-term follow up (2 week, 1 month, 3 month); data will be reported through study completion (3 month follow up)item assessing frequency of use and length of time not using; higher frequency of use = worse outcome; higher length of time not using = better outcome
Changes in smartphone addiction pronenessAssessed at lab 1 (week 1) and long-term follow up (2 week, 1 month, 3 month); data will be reported through study completion (3 month follow up)Assessed via the smartphone addiction proneness scale; will use total score (sum); response options range from 1 to 4; total scores (range from 15 to 60), higher scores = more addiction proneness (worse outcome)
