Brief Online Interventions for Alcohol Use: A Crowdsourced Study
In Brief
A clinical study evaluating Normative Feedback, Inhibitory Control Training, and 1 other intervention for Alcohol Use Disorder. Completed, enrolled 444 participants across 1 site.
Detailed Summary
The purpose of this study is to test the feasibility and acceptability of delivering cognitive training over mTurk. Subjects will be randomized to a 1) inhibitory control training condition, 2) working memory training condition, or 3) control training condition. Recent studies have also demonstrated the feasibility and potential efficacy of delivering brief normative feedback to reduce alcohol consumption through mTurk. In these brief interventions, subjects are provided information about their drinking compared to their same age and gendered peers. Approximately half of the subjects in each cognitive training group will receive normative feedback to evaluate effects on alcohol consumption and possible interactions with cognitive training. This study will focus on alcohol use given the ease and clinical acceptance of alcohol use self-report as a primary outcome.
Study Details
Timeline
Interventions
Subjects assigned to normative feedback will be directed to a statement standardized based on subjects' reported average number of standard drinks per week, age, and gender.
The inhibitory control training task is a modified version of the Cued Go/No-Go tasks (Weafer and Fillmore, 2012; Miller et al. 1991) and is based on a task currently used in our laboratory targeting cocaine inhibitory control.
A battery of working memory tasks will be used during the intervention period. These tasks were selected from previous research evaluating working memory training in substance use disorder (Bickel et al., 2011b; Houben et al., 2011b). Tasks will include visuospatial working memory task, digit span task, letter span task, and the n-back task.
