Event-level effects of alcohol, cannabis, and simultaneous alcohol and cannabis use on bystander intentions in response to hypothetical situations among college women.

Bystanders can play an important role in preventing alcohol-related harm (e.g., unintentional injury) or sexual aggression.

Examining Between- and Within-subjects Effects of Posting and Exposure to Alcohol-Related Social Media Content on Drinking Over Time.

Objective: Social media content featuring alcoholic beverages is posted and viewed by college students. Limited longitudinal research suggests that increased alcohol-related content (ARC) posting and exposure is associated with increased alcohol consumption among college students over time. Emerging evidence suggests this association may be bidirectional, with drinking predicting later ARC posting.

College Student Social Network Characteristics and Alcohol Use: Differences (and Similarities) Based on Sexual Identity and Attraction.

Objective: Sexual minority (SM) college students have higher alcohol use and alcohol-related consequences than heterosexual students. Peers are salient determinants of young adult drinking, and examining social network characteristics is useful for understanding peer influence. This study used social network methods to understand network characteristics, alcohol use (i.

Prior Sexual Aggression as a Moderator of an Integrated Alcohol and Sexual Assault Prevention Program for Heavy Drinking College Men: A Brief Report.

Objective: Sexual aggression and heavy drinking are interrelated concerns among college men. As a result, integrated prevention interventions now exist to address co-occurring risk for sexual aggression and heavy drinking. The Sexual Assault and Alcohol Feedback and Education (SAFE) program is a multi-session integrated alcohol and sexual assault prevention program for college men that addresses alcohol use, sexual activity, social norms, alcohol-related sexual consequences, understanding of consent, and engagement in bystander intervention.

Examining the Impact of Simultaneous Alcohol and Cannabis Use on Alcohol Consumption and Consequences: Protocol for an Observational Ambulatory Assessment Study in Young Adults.

Background: There is significant conflicting evidence as to how using cannabis while drinking alcohol (ie, simultaneous alcohol and cannabis use) impacts alcohol volume consumed, patterns of drinking, and alcohol-related consequences. The impact of simultaneous use on drinking outcomes may be influenced by several within-person (eg, contextual) and between-person (individual) factors.

Objective: This study was designed to examine naturalistic patterns of alcohol and cannabis use to understand how simultaneous use may impact drinking outcomes.

Alcohol Feedback, Reflection, and Morning Evaluation (A-FRAME): Refining and testing feasibility and acceptability of a smartphone-delivered alcohol intervention for heavy-drinking young adults.

Background: Young adults drink heavily and experience negative alcohol consequences. To capitalize on mornings after drinking as an optimal time to intervene, we developed a novel, theory-based personalized feedback intervention (PFI) called Alcohol Feedback, Reflection, and Morning Evaluation (A-FRAME), to reduce heavy drinking. An initial prototype was refined via feedback from college students who drink heavily.

Assessing the feasibility, acceptability, and initial efficacy of a multiple behavior change intervention addressing alcohol use, sexual risk taking, and bystander intervention.

Objective: Prevention programs that address the intersecting health problems of risky alcohol use, unsafe sexual behaviors, and sexual violence are needed. This pilot project assessed the feasibility, acceptability, and preliminary efficacy of a two-session group-based intervention, Sex Positive Lifestyles: Addressing Alcohol & Sexual Health (SPLASH), targeting these highly interconnected risks for college students across genders.

Method: A total of 217 participants (51.

Detecting and Understanding Social Influence During Drinking Situations: Protocol for a Bluetooth-Based Sensor Feasibility and Acceptability Study.

Background: High-risk alcohol consumption among young adults frequently occurs in the presence of peers who are also drinking. A high-risk drinking situation may consist of particular social network members who have a primary association with drinking. Fine-grained approaches such as ecological momentary assessment (EMA) are growing in popularity for studying real-time social influence, but studies using these approaches exclusively rely on participant self-report.

A Bluetooth-Based Smartphone App for Detecting Peer Proximity: Protocol for Evaluating Functionality and Validity.

Background: While ecological momentary assessment (EMA) is commonly used to study social contexts and social influence in the real world, EMA almost exclusively relies on participant self-report of present circumstances, including the proximity to influential peers. There is the potential for developing a proximity sensing approach that uses small Bluetooth beacons and smartphone-based detection and data collection to collect information about interactions between individuals passively in real time.

Objective: This paper aims to describe the methods for evaluating the functionality and validity of a Bluetooth-based beacon and a smartphone app to identify when ≥2 individuals are physically proximal.

Experimentally Induced Reductions in Alcohol Consumption and Brain, Cognitive, and Clinical Outcomes in Older Persons With and Those Without HIV Infection (30-Day Challenge Study): Protocol for a Nonrandomized Clinical Trial.

Background: Both alcohol consumption and HIV infection are associated with worse brain, cognitive, and clinical outcomes in older adults. However, the extent to which brain and cognitive dysfunction is reversible with reduction or cessation of drinking is unknown.

Objective: The 30-Day Challenge study was designed to determine whether reduction or cessation of drinking would be associated with improvements in cognition, reduction of systemic and brain inflammation, and improvement in HIV-related outcomes in adults with heavy drinking.

Associations between frequency of exposure to peer-generated alcohol-related posts and alcohol use within a social network of college students.

Peer alcohol use, commonly assessed via perceptions of how many drinks peers consume, is a robust predictor of college drinking. These perceptions are formed by in-person exposure to peer drinking but also may be affected by seeing alcohol-related content (ARC) shared on peer social media accounts. Most research assesses exposure by asking about the frequency of ARC sharing by a whole friend group, potentially missing influences from specific friends.

Dynamic social network analysis of a brief alcohol intervention trial in heavy-drinking college students shows spillover effects.

Background: Heavy-drinking college students tend to have close social networks, and there is theoretical and empirical support for the idea that behavior change can spread through those networks via close ties. The objective of this research was to determine whether intervention-induced behavior change in a subset of heavy drinkers in a sociometric (whole) college class-year social network is transmitted to other heavy drinkers in the network, resulting in reduced behavioral risk and change in network ties.

Methods: We conducted a controlled trial in which most of a first-year college class (N = 1236; 56.

Navigating ethical challenges in psychological research involving digital remote technologies and people who use alcohol or drugs.

Digital and remote technologies (DRT) are increasingly being used in scientific investigations to objectively measure human behavior during day-to-day activities. Using these devices, psychologists and other behavioral scientists can investigate health risk behaviors, such as drug and alcohol use, by closely examining the causes and consequences of monitored behaviors as they occur naturalistically. There are, however, complex ethical issues that emerge when using DRT methodologies in research with people who use substances.

Measuring Exposure to the Hazardous Drinking of Others and Perceived Opportunity to Intervene as a Bystander.

Objective: Excessive alcohol use is very prevalent among young adults, and consequences of drinking are often observed by witnesses. Understanding the circumstances under which witnesses of risky alcohol use help others and whether they perceive these circumstances as an opportunity to engage in bystander intervention are important, but valid measures of these constructs are needed. The current study is a psychometric evaluation of the Exposure to Hazardous Drinking in Others (EHDO) scale and a single-item indicator of Perceived Alcohol-Related Bystander Opportunity (PARBO).

Integrated Alcohol Use and Sexual Assault Prevention Program for College Men Who Engage in Heavy Drinking: Randomized Pilot Study.

Background: Sexual assault is prevalent on college campuses and most commonly is perpetrated by men. Problematically, there is a dearth of evidence-based prevention programs targeting men as perpetrators of sexual aggression. The Sexual Assault and Alcohol Feedback and Education (SAFE) program is an integrated alcohol and sexual assault prevention intervention for college men who engage in heavy drinking that aims to address sexual aggression proclivity and alcohol use outcomes by incorporating social norms theory, bystander intervention, and motivational interviewing.

Phosphatidylethanol vs Transdermal Alcohol Monitoring for Detecting Alcohol Consumption Among Adults.

Importance: Alcohol biomarkers can improve detection of heavy alcohol use in clinical care, yet cutoffs for phosphatidylethanol (PEth), a blood biomarker, have not been established.

Objective: To determine the optimal cutoff for PEth for heavy alcohol consumption in a study of middle-age and older adults.

Design, Setting, And Participants: This was a 4-week diagnostic study of adults with paroxysmal atrial fibrillation (AF) and current alcohol consumption, recruited from general cardiology and cardiac electrophysiology outpatient clinics from September 2014 to September 2019.

Preventing alcohol use post-bariatric surgery: patient perspectives on a technology-based approach.

Background: Nearly two-thirds of patients engage in alcohol use after bariatric surgery, while a substantial number meet criteria for alcohol use disorder after their procedure. Given that pre-surgical education may not be sufficient, alternative methods of preventing post-surgical drinking are needed. We sought feedback on a proposed technology-based intervention to reduce alcohol use for individuals who have undergone bariatric surgery.

Use of the BACtrack Skyn alcohol biosensor: Practical applications for data collection and analysis.

Aims: Alcohol biosensors, including the BACtrack Skyn, provide an objective and passive method of continuously assessing alcohol consumption in the natural environment. Despite the many strengths of the Skyn, six key challenges in the collection and processing of data include (1) identifying consumed alcohol; (2) identifying environmental alcohol; (3) identifying and determining the source of missing or invalid data; (4) achieving high participant adherence; (5) integrating Skyn and self-report data; and (6) implications for statistical inference. In this report we outline these challenges, provide recommendations to address them and identify future needs.

Multi-level influences on increased overdose risk behaviors during the COVID-19 pandemic among people who use drugs in Rhode Island: a qualitative investigation.

Background: The ongoing COVID-19 pandemic has disproportionately affected structurally vulnerable populations including people who use drugs (PWUD). Increased overdose risk behaviors among PWUD during the pandemic have been documented, with research underscoring the role of influencing factors such as isolation and job loss in these behaviors. Here, we use qualitative methods to examine the impact of the COVID-19 pandemic and pandemic-related response measures on drug use behaviors in a sample of PWUD in Rhode Island.

Patient perceptions regarding alcohol use after bariatric surgery.

Introduction: Patients who have undergone bariatric surgery are at increased risk of an alcohol use disorder. Though patients understand this risk, the majority engage in post-surgical alcohol use. This suggests that education alone is not sufficient to reduce post-surgical drinking.
