Objective: Brief motivational interventions (BMIs) that include personalized drinking feedback delivered in a motivational interviewing (MI) style have demonstrated reductions in drinking across numerous clinical trials with emerging adults (EAs) ages 18-25. However, effect sizes for these BMIs are generally small to moderate and drinking reductions are often not maintained beyond short-term follow-ups. Additionally, EAs may be more interested in approaches that highlight wellness, mood enhancement, or goal pursuit rather than programs focused exclusively on reducing alcohol-related risk. Thus, there is a need to evaluate novel intervention content as an alternative or supplement to BMIs in this high-risk population. Method: This scoping review examined studies of novel intervention elements to reduce alcohol consumption among EAs. Eligible studies were published in peer-reviewed journals in English from January 2015 to September 2021 and evaluated novel brief interventions, operationalized as one to five sessions focused on alcoholrelated outcomes with key content beyond what has typically been included in alcohol BMIs. Results were categorized as additions to BMIs or stand-alone interventions and were synthesized within these categories by theoretical approach. Results: Although standard in-person BMIs have the greatest empirical support, there are a variety of alternative intervention approaches that might enhance health and wellness and that can be feasibly integrated with BMIs or offered as an appealing "gateway" to increase help-seeking among EAs who drink alcohol. Conclusions: More research is needed to empirically evaluate both the relative efficacy of supplements and stand-alone alternatives to BMI among higher risk EAs and their potential for widespread dissemination.
Public Health Significance StatementEmerging adults (EAs; ages 18-25) report greater alcohol use than any other age group, yet very few voluntarily participate in existing intervention programs, and those that do generally report only small to moderate reductions in drinking. This study reviewed novel intervention elements for EAs that have the potential to augment existing evidence-based brief motivational intervention approaches.
