Brief ROC Training Effects on Alcohol Drinking
The goal of the proposed study is to examine whether a single session of training in regulation of craving (ROC-T) affects alcohol drinking. The study will consist of (1) a basic screening (phone and/or online) and an in-person visit, to determine eligibility and conduct pre-intervention baseline assessments; (2) a training (ROC-T) visit, (3) a post-intervention assessment visit, and (4) 1-2 phone/online follow-up assessments.
The study will take up to 10 hours of the participants' time.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: CRAVING REGULATION
In the CRAVING REGULATION condition, participants will first read a brief essay about the adverse consequences of drinking alcohol.
Then, participants may complete a comprehension check consisting of questions to ensure that they understood and encoded the content of the essays.
Participants will be trained to use the information to inform the strategy they will use in the regulation of craving training (ROC-T).
A single trial in the regulation of craving training will have two possible instructions: (a) STRATEGY: implement the strategy ("bring to mind the negative facts from the essay") and (b) LOOK: to merely observe the image and allow natural responses to come.
Participants will follow the instructions; followed by an alcohol-related picture, a brief delay, and will then rate their craving.
Participants will then be instructed to use this strategy in daily life situations when they might drink.
|
Participants in the ROC-T condition will be trained to use a strategy that instructs them to think of the negative outcomes associated with alcohol drinking while looking at alcohol-related images.

Placebo Comparator: CONTROL (NO REGULATION)
In the CONTROL condition, participants will first read a brief essay about a non-alcohol-related topic (e.g., color perception).
Then, participants will complete a comprehension check consisting of questions to ensure that they understood and encoded the content of the essays.
Participants will view images of objects that are unrelated to alcohol.
Furthermore, participants in the control condition will not practice any strategy in the regulation of craving task (ROC-T).
That is, in the CONTROL condition, participants would merely observe the image and allow natural responses to come (i.e., LOOK instruction) and rate how colorful is each item (this controls for task time and experiment setting).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Timeline followback (TLFB)
Time Frame: Baseline (first visit) to post-intervention (an average of one week after first visit)
|
The Alcohol TLFB is a drinking assessment method that obtains estimates of daily drinking.
|
Baseline (first visit) to post-intervention (an average of one week after first visit)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Frequency of regulating drinking + craving.
Time Frame: Will be measured at post-intervention (one week after first visit)
|
Participants will be asked to report their craving regulation (if any) since the intervention.
In order to assess the level of craving regulation the participants will answer several questions in our craving regulation questionnaire.
This assessment will include questions about the number of attempts at craving regulation, the number of times the participant intended to regulate craving, one's confidence in one's ability to regulate craving, the level of motivation to regulate drinking before each drinking episode, and the participant's intention to regulate drinking in the future.
Finally, participants will be asked how many times they were thinking of negative consequences in general and while experiencing alcohol craving.
|
Will be measured at post-intervention (one week after first visit)
|
Timeline followback (TLFB)
Time Frame: First visit, post-intervention (one week after first visit), follow-up (two weeks after first visit)
|
The Alcohol TLFB is a drinking assessment method that obtains estimates of daily drinking.
|
First visit, post-intervention (one week after first visit), follow-up (two weeks after first visit)
