Brief Summary

The current project uses a web-based program called the Expectancy Challenge Alcohol Literacy Curriculum (ECALC) to reduce alcohol use and associated harms among college students. Participants complete the interactive program in 50 minutes, and then provide daily, real-time data on expectancies and alcohol use for 3 weeks after intervention, and again for one week at 13 and 25 weeks after intervention. One group will also receive biweekly boosters delivered via smart phone to assess their impact on intervention decay over time. It is hypothesized that ECALC effects may decay over time, and that biweekly boosters will prevent this decay. Access to the ECALC is available on request from the principal investigator.

Outcome Measures

Primary Outcomes (6)

• Change from Baseline in Alcohol Expectancies Measured Weekly with CEOA

  Expected effects of alcohol use measured with self-report survey. The survey is the 38 item Comprehensive Effects of Alcohol Scale (CEOA), a validated measure of alcohol expectancies. Participants complete the CEOA online on their mobile device and enter responses to each item. Scores range from 0 to 114 with higher scores indicating greater expectation of effects of consuming alcohol.

  Weeks 1, 2, 3, 4, 13, and 26

• Change from Baseline in Alcohol Use Measured Weekly with Retrospective Self-report Measure

  Self-reported alcohol use, quantity and frequency of consumption in standard drink format. Participants complete an online survey on their mobile device and enter the number of standard drinks consumed each day and number of hours spent drinking each day over the previous week.

  Weeks 1, 2, 3, 4, 13, and 26

• Change from Baseline in Alcohol-related Harms Measured Weekly with Retrospective Self-report Survey

  Self-reported Negative consequences associated with alcohol use measured with self-report survey. Participants complete an online survey on their mobile device. The survey is the Young Adult Alcohol Consequences Questionnaire. A 48-item validated measure with scores ranging from 0 to 67, higher scores indicate more harms.

  Weeks 1, 2, 3, 4, 13, and 26

• Change from Baseline in Sociocultural Attitudes Towards Appearance Measured Weekly with Self-report Survey

  Attitudes toward personal appearance measured with self-report survey. Participants complete an online survey on their mobile device. The survey is the Sociocultural Attitudes Towards Appearance Questionnaire-4. A 22-item validated measure with scores ranging from 0 to 110, higher scores indicate more sociocultural emphasis on personal appearance and body image.

  Weeks 1, 2, 3, 4, 13, and 26

• Change from Baseline in Alcohol Expectancies Measured Daily with Ecological Momentary Assessment (EMA)

  Expected effects of alcohol use measured with 8 item self-report survey. Participants complete an online survey on their mobile device and enter responses to items each day. Scores range from 0 to 24 with higher scores indicating greater expectation of effects of consuming alcohol. Items were selected from the Comprehensive Expected Effects of Alcohol Scale (CEOA).

  Daily for Weeks 1, 2, 3, 4, 13, and 26

• Change from Baseline in Alcohol Use Measured Daily with Ecological Momentary Assessment (EMA)

  Self-reported alcohol use, quantity and frequency of consumption in standard drink format. Participants complete an online survey on their mobile device and enter the number of standard drinks consumed each day.

  Daily for Weeks 1, 2, 3, 4, 13, and 26
