Efficacy of a Web-Based Alcohol Intervention for High School Students

This study evaluates the efficacy of the eCHECKUP TO GO as an intervention to reduce underage drinking and the associated negative consequences among high school seniors. The aim of this project is to provide a brief, low cost intervention that can be easily disseminated as a school-based intervention to address this important public health problem.

Treatment and study plan

eCHECKUP TO GO

Behavioral

eCHECKUP TO GO is a personalized normative feedback intervention intended to help participants make better choices about alcohol use by changing beliefs about alcohol, alcohol expectancies, and perceptions of peer drinking

Primary outcomes

  1. Weekly Drinking

    Time frame: Baseline, 1 month follow-up, and 6-month follow up

    Daily Drinking Questionnaire

    Weekly drinking was assessed with the question "Given that it is a typical week, please write the number of drinks you probably would have each day." A response scale is provided for each day of the week (e.g., Monday__, Tuesday__, etc.)." Weekly drinking was calculated by combining the reports for the seven days of the week (sum of the 7 days).

    Minimum = 0; Maximum = none

    Sample score range: Minimum = 0; Maximum = 26

    Higher scores are worse outcomes

  2. Peak Drinking Quantity

    Time frame: Baseline, 1 month follow-up, and 6-month follow up

    Quantity ⁄Frequency ⁄Peak Questionnaire

    Peak drinking quantity was assessed with the question "What is the most number of drinks that you have consumed on any given night in the past month?"

    Minimum = 0; Maximum = none

    Sample score range: Minimum = 0; Maximum = 25

    Higher scores are worse outcomes

  3. Frequency of Alcohol Use

    Time frame: Baseline, 1 month follow-up, and 6-month follow up

    Quantity ⁄Frequency ⁄Peak Questionnaire

    Frequency of alcohol use was assessed with the question "How often do you use alcohol?" with responses provided on an 8-point Likert scale with options ranging from "0" to "7" ("Do not drink alcohol" to "Every day"). Items were reverse scores so higher scores represent higher levels of drinking frequency.

    Minimum = 0; Maximum = 7

    Sample score range: Minimum = 0; Maximum = 7

    Higher scores are worse outcomes

  4. Blood Alcohol Concentration

    Time frame: Baseline, 1 month follow-up, and 6-month follow up

    Blood alcohol concentration was calculated using the Widmark Formula (1932/1981); BAC = [Alcohol consumed in grams / (Body weight in grams x r)] x 100. In this formula, "r" is the gender constant.

    Minimum = 0; Maximum = none

    Sample score range: Minimum = 0; Maximum = .62

    Higher scores are worse outcomes

  5. Heavy Episodic Drinking

    Time frame: Baseline, 1 month follow-up, and 6-month follow up

    Heavy Episodic Drinking is defined as having 5 or more drinks in a row for males and 3 or more for females in a 2 hour period in the past month. The number of drinks was based on research by Donovan (2009) establishing cut-points for children and adolescents.

    Participants were asked:

    "Males: Think back over the last two weeks. How many times have you had 5 or more drinks in a two hour period?" "Females: Think back over the last two weeks. How many times have you had 3 or more drinks in a two hour period?"

    Minimum = 0; Maximum = none

    Sample score range: Minimum = 0; Maximum = .76

    Higher scores are worse outcomes

Secondary outcomes

  1. Alcohol-Related Consequences

    Time frame: Baseline and 6-month follow up

    Rutgers Alcohol Problems Inventory

    Alcohol-related consequences were measured using the Rutgers Alcohol Problems Inventory. The Rutgers Alcohol Problems Inventory is a 23-item scale. Participants were asked "How many times have the following scenarios happened to you while you were consuming alcohol or as a result of your drinking in the past 30 days." Responses were measured on a 5-point scale ranging from 0 (never) to 4 (more than 10 times). A total consequence score is created by summing the 23 items.

    Minimum = 0; Maximum = 92

    Sample score range: Minimum = 0; Maximum = 24

    Higher scores are worse outcomes
