Underage Drinking

Brief summary

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.

Interventions

BEHAVIORALeCHECKUP TO GO

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

Design outcomes

Primary

Measure	Time frame	Description
Weekly Drinking	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
Peak Drinking Quantity	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
Frequency of Alcohol Use	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
Blood Alcohol Concentration	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
Heavy Episodic Drinking	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

Measure	Time frame	Description
Alcohol-Related Consequences	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
