A Randomized Clinical Trial: Examining the Efficacy of eCHECKUP TO GO Combined With a Brief Parent-based Intervention to Reduce High School Student Drinking

Prevalence rates of high school alcohol use suggest 61.6% of high school students have used alcohol by their senior year and 1 in 3 students report alcohol use past 30-days. High school risky drinking is associated with negative consequences including impaired neurocognitive functioning, academic problems, hangovers, passing out, unwanted sex, dating violence, suicide attempts, illicit drug use, riding with impaired drivers, and impaired driving.

While past research supports the efficacy of interventions in delaying the initiation of alcohol use implemented in middle school and early high school, research shows drinking by older high schoolers is problematic and interventions for older high schoolers remain limited. Implementation with high schoolers has always been difficult to sustain following the completion of the grant funding period due to large costs associated with personnel to hire, train, and supervise teachers and staff to implement interventions with fidelity. As an alternative, brief web-based personalized feedback interventions that do not require staffing or costs to implement to large numbers of students have shown promise (e.g., eCHECKUP TO GO; eCTG). Our preliminary work, including our funded NIAAA R21 study, supporting this proposal has shown eCTG is efficacious in changing normative perceptions of peer drinking frequency and drunkenness, positive alcohol expectancies, and reducing both alcohol use and consequences among high school students. The proposed research will expand on these findings by conducting a randomized controlled trial using the eCHECKUP TO GO (eCTG) alone and combined with an efficacious brief electronic-Parent-Based Intervention on a nationally representative sample of high school juniors and seniors.

The design is a four-arm RCT: eCTG, eCTG+, Parent-Only, and Control. Data collection will occur across 5 waves (pre-intervention baseline, 3-, 6-, 9-, 12- month follow-ups) for all arms. In all arms there is one wave for parents (3-month only).
