Lifetime risk for developing an alcohol use disorder increases with earlier onset of alcohol consumption. This risk may reflect a tendency for escalated alcohol intake among youth due to immature executive control, leading to more frequent binge drinking, which is associated with more alcohol-related problems. Binge drinking is associated with deficits in behavioral flexibility, which may suggest impaired control networks that contribute to automatic behavior. Individuals with an alcohol or substance use disorder (A/SUD) exhibit attentional bias toward drug- or alcohol-related stimuli that have attained salience through consistent use. Reward history increases attention towards non-drug stimuli, even among individuals with no lifetime A/SUD. Preliminary data (from Dr. Boettiger's lab) from a nationally representative US adult sample using data collected via Prolific found that a questionnaire measure of mindfulness moderates the relationship between alcohol misuse and attention to reward. Given evidence that heavy alcohol drinking impairs behavioral flexibility, which in turn promotes escalating intake, insight into the relationship between mindfulness and behavioral flexibility could inspire new strategies to prevent alcohol and substance use disorders in people at elevated risk.
This is a feasibility pilot study of training freshman college students, with a history of alcohol binge drinking, mindfulness and meditation skills in 4 virtual visits. Before and after the virtual intervention, behavioral flexibility will be measured using a reward-driven attentional bias (Reward-AB) computerized task, and C-reactive protein (CRP) levels will be collected. Upon arrival for the first visit, participants will be screened for any current alcohol intoxication or recent substance use, followed by a mental health assessment with the Mini-International Neuropsychiatric Interview (MINI). The participant will then have blood collected by finger prick, complete a Reward-AB task, and fill out some paper surveys. During visits 2 through 5, participants will complete virtual training on either mindfulness and meditation skills, or navigating college skills. Each visit will last approximately 90 minutes, starting with the completion of a few online surveys. Visit 6 is similar to visit 1, without the health interview. Participants will be contacted one month following the date of the 6th study visit to complete online surveys. Visit 1: * Written consent, MINI interview, urine drug screen and breathalyzer alcohol test, CRP assay, Reward-AB task. * Randomization to either the Koru Mindfulness (KM) intervention or the Navigating College (NC) control group. Visits 2-5: * Surveys completed online through REDCap. * 75 minutes of instructor-led discussion * Breakout sessions for participants to share thoughts and experiences in response to instructor's prompt. Visit 6: Similar to visit 1, without repeating the MINI interview. Follow-up: One month after the conclusion of visit 6, participants will be contacted via email with a link to REDCap to complete several surveys. Reward-Attentional Bias (Reward-AB) Task: This computerized task will be used to measure attentional bias pre- and post-intervention. The task includes a training and testing portion, each of which are adapted from tasks that measure the influence of reward on visual attention. Navigating College (NC) Control Group Training: Topics discussed during each training visit include: habits, roommate issues, homesickness, the internet (week 1); strategies when sinking, study skills, getting involved, habit formation (week 2); Hungry, Angry, Lonely, and Tired (HALT), gateway habit (week 3); and academic success tips, taking notes, and procrastination (week 4). Koru Mindfulness (KM) Intervention Training: Topics discussed during each training visit include: belly breathing, dynamic breathing, body scan (week 1); walking meditation, gatha (week 2); guided imagery, labeling thoughts (week 3); eating meditation, and labeling feelings (week 4). Daily Logging of Skills: Participants in the NC intervention will be asked to journal by hand or via Qualtrics every day for \>10 minutes, on anything related to the topics learned during that week's training visit. Participants in the KM intervention will be asked to practice every day for \>10 minutes any mindfulness or meditation skill previously learned during training visits, in addition to logging practice of skills and reflection on the experience using the Koru application.

The Koru Basic curriculum consists of four weekly interactive 75-minute classes delivered online through Zoom. Each class consists of an overview of 2-3 skills, group practice of the skills, and group reflection. Topics discussed during each training visit include: belly breathing, dynamic breathing, body scan (week 1); walking meditation, gatha (week 2); guided imagery, labeling thoughts (week 3); eating meditation, and labeling feelings (week 4). Participants are instructed to practice a skill for 10 minutes/day and log any reflection on that practice using the Koru phone application.
With topics discussed from the Freshman Survival Guide book, this training provides a closely matched active control group for KM Training. The training consists of four weekly 75-minute classes delivered online through Zoom. Each class consists of lecture and group discussions on topics related to navigating college. Topics discussed during each training visit include: habits, roommate issues, homesickness, the internet (week 1); strategies when sinking, study skills, getting involved, habit formation (week 2); HALT, gateway habit (week 3); and academic success tips, taking notes, and procrastination (week 4). Participants are instructed to journal about learned information and skills for 10 minutes/day.

Participant Retention
Participant retention will be measured by the percentage of enrolled participants remaining in the study after 6 visits.
Time frame: 10 weeks
Compliance With Independent Training of Skills
To determine participant compliance with training skills learned during each of the 4 virtual visits, the average number of journal entries logged during the 4 weeks of training, for each group, is calculated as a total score (6 times/week x 4 weeks = 24). Scores range from 0 to 24, with higher scores indicating greater compliance with independent training.
Time frame: 6 weeks
Average CEQ Ratings - Credibility Subscale
The Credibility subscale of the Credibility/Expectancy Questionnaire (CEQ) measures the the credibility of an intervention in clinical studies. The word "therapy" is replaced with "intervention" and modified to reflect the intent of the intervention (i.e., to improve skills in navigating college). Three items are each scored on a range from 0-9 and averaged together for a credibility rating, with high scores indicating greater perceived credibility of the intervention.
Time frame: 1 week
Average CEQ Ratings - Expectancy Subscale
The Expectancy subscale of the Credibility/Expectancy Questionnaire (CEQ) measures the the expectancy of an intervention in clinical studies. The word "therapy" is replaced with "intervention" and modified to reflect the intent of the intervention (i.e., to improve skills in navigating college). Three items are each scored on a range from 0-9 and averaged together for an expectancy rating, with high scores indicating greater perceived expectancy of positive outcomes of the intervention.
Time frame: 1 week
Mean Change in Emotional Distress Scores
The Depression, Anxiety and Stress Scale-21 (DASS-21) is composed of three self-report scales that measure depression, anxiety and stress. Items are rated on a Likert-type scale (0=Did not apply to me at all, to 3=Applied to me very much, or most of the time). Scores for the three subscales are calculated by summing the scores for the relevant items. The severity rating for Depression are Normal: 0-4, Mild: 5-6, Moderate: 7-10, Severe: 11-13, and Extremely Severe: 14-21; for Stress the ratings are Normal: 0-7, Mild: 8-9, Moderate: 10-12, Severe: 13-16, and Extremely Severe 17-21; and for Anxiety the ratings are Normal: 0-3, Mild: 4-5, Moderate: 6-7, Severe: 8-9, and Extremely Severe: 10-21. The total DASS-21 score is calculated by summing all three subscales, with a range from 0-63. For all scales, higher scores indicate greater emotional distress.
Time frame: Baseline, Week 6
