Emerging adults in substance misuse intervention: preintervention characteristics and responses to a motivation-enhancing program

A Lifestyle Risk Reduction Model for Preventing High-Risk Substance Use Across the Lifespan

While effective models of alcohol and drug prevention exist, they often focus solely on youth or young adults. This article describes the Lifestyle Risk Reduction Model (LRRM), an approach applicable across the lifespan. The intent behind the LRRM is to guide the development of prevention and treatment programs provided to individuals and small groups. The LRRM authors' goals are to help individuals reduce risk for impairment, addiction, and substance use's negative consequences. The LRRM identifies six key principles that conceptualize the development of substance-related problems by drawing parallels with health conditions, such as heart disease and diabetes, which often result from combined effects of biological risk and behavioral choices. The model also proposes five conditions that describe important steps for individuals as they progress toward greater perception of risk and lower risk behavior. One LRRM-based indicated prevention program (Prime For Life) shows positive results in cognitive outcomes and in impaired driving recidivism for people across the lifespan. The model emphasizes common elements across the lifespan, responds to contexts and challenges that change across the life course, complements other models, and is usable for universal, selective, and indicated prevention programs.

The Influence of a Brief Alcohol Intervention on Alcohol Use Trajectories in Nonstudent Emerging Adult Drinkers

Background: This study sought to inform research with noncollege-attending emerging adults, an at-risk, and understudied population, by identifying patterns of response following a brief alcohol intervention. This study was a reanalysis of data from a randomized controlled intervention trial testing a brief, personalized feedback alcohol intervention targeting nonstudent emerging adult drinkers. Objectives: The study aims were to (1) model intervention response by identifying subgroups characterized by changes in heavy drinking (i.e. peak use, number of binges during a typical week, proportion of binge days, peak estimated blood alcohol concentration [eBAC]) following the alcohol intervention, and (2) distinguish subgroups on factors related to intervention response (i.e. perceived norms regarding how much peers drink, alcohol use severity, mental health symptoms, and readiness to change). Methods: Participants were 81 (64.2% men) nonstudent heavy drinkers between ages 18-25 years (average age = 22.04) recruited from the community. Results: Findings revealed two latent subgroups that exhibited differential response to the intervention (i.e. intervention "responders" and "nonresponders"). Further, responders reported higher pre-intervention descriptive normative perceptions and alcohol use severity. Conclusions/Importance: The current investigation contributed to knowledge regarding for whom brief alcohol interventions work in the short term within nonstudent emerging adults and could inform future research to facilitate behavior change in those unresponsive to intervention efforts.
