Project e-PBI+ - Parent Intervention to Reduce College Student Drinking and Cannabis Use

Summary

College students' risky drinking and cannabis use are major public health problems. The harms associated with risky drinking have been well-documented (such as deaths, blackouts, injuries, assaults, arrests, sexual consequences, academic consequences). Both college health administrators and parents have requested electronic parent-based interventions (e-PBIs) with additional content on cannabis. Parents have demonstrated ample motivation to communicate with their teens. The proposed research will attempt to enhance an existing effective e-PBI, curb the alarming trends noted in the literature, and move the field forward by conducting a randomized controlled trial testing a modified version of the e-PBI that includes updated content including the most up-to-date scientific information from cannabis studies (e-PBI+).

Interventions

BEHAVIORAL

e-PBI+

The e-PBI+ is a preventive parent-based intervention emphasizing parent-teen communication on drinking/risks of alcohol abuse, with the addition of data-driven cannabis content to guide parent communications with their students (e.g., cannabis content focusing on the endocannabinoid system; acute and chronic cannabis use effects on the brain, cognition, and development; THC potency in present-day cannabis; cannabis use effects on mental and physical health, including psychosis, depression, and anxiety; respiratory/cardiovascular/sleep problems; cannabidiol (CBD) content, myths; and cannabis effects on psychosocial function). Together the goals are to reduce alcohol and cannabis use in college students.

BEHAVIORAL

e-PBI

The e-PBI is currently a model prevention resource at NIAAA's College Alcohol Intervention Matrix and the research was discussed in the most recent Surgeon General's Report as one of two prevention approaches that met the rigorous criteria to be considered "efficacious". The first section of the e-PBI provides an introduction to the problem of substance use. The second section focuses on specific skill building strategies that parents can use to improve communication channels with their teen. Third is a section that addresses peer influence and provides strategies for developing assertiveness. The fourth section is an in-depth discussion of underage drinking, physiological and psychological effects, mixing alcohol with other drugs, motives for why students drink and don't drink, warning signs, risky binge-type drinking, impaired driving, riding with impaired drivers, alcohol and sexual assault, and how to communicate about parents' experiences when they were young.
