Randomized controlled trial of a minimal versus extended Internet-based intervention for problem drinkers: study protocol.

Cunningham JA, Hendershot CS, Rehm J - BMC Public Health (2015)

Bottom Line: Participants will be sent to a password-protected Internet site and, upon signing in, will be randomized to be provided access to the minimal or extended Internet-based intervention.Six-month, twelve-month, and two-year drinking outcomes will be compared between experimental conditions.The primary hypothesis is that participants in the extended Internet intervention condition will display significantly improved drinking outcomes at twelve months compared to participants in the minimal intervention.

ABSTRACT

Background: Problem drinking causes great harm to the person and to society. Most problem drinkers will never seek treatment. The current trial will test the efficacy of two Internet interventions for problem drinking - one minimal and the other extended - as an alternate means of providing help to those in need.

Methods/design: A double blinded, four-wave panel design with random assignment to two experimental conditions will be used in this study. Participants will be recruited through a comprehensive recruitment strategy consisting of online and print advertisements asking for people who are 'interested in helping us develop and evaluate Internet-based interventions for problem drinkers.' Potential participants will be screened to select problem drinkers who have home access to the Internet. Participants will be sent to a password-protected Internet site and, upon signing in, will be randomized to be provided access to the minimal or extended Internet-based intervention. Six-month, twelve-month, and two-year drinking outcomes will be compared between experimental conditions. The primary hypothesis is that participants in the extended Internet intervention condition will display significantly improved drinking outcomes at twelve months compared to participants in the minimal intervention.

Discussion: The findings of this trial will contribute to the growing literature on Internet interventions for problem drinkers. In addition, findings from this trial will contribute to the scarce literature available evaluating the long-term efficacy of brief interventions for alcohol problems.

Fig1: Overview of the proposed intervention trial.

Mentions: This is a double-blind, four-wave panel randomized control trial of two IBIs for alcohol problems, with three follow-up periods (6 months, 12 months and 2 years). A comprehensive recruitment strategy using online and print advertisements will be used to recruit current drinkers interested in helping researchers “revise and evaluate Internet-based interventions for alcohol users.” Interested potential participants will be directed to complete an online consent form and a baseline questionnaire. Those found to be eligible based on their responses to the baseline questionnaire will be provided with a unique password to the study website. Upon accessing the website, they will be randomized into one of the two interventions: the minimal Internet-based Check Your Drinking personalized feedback intervention or the extended Internet-based Alcohol Help Center. Only participants who use their password and access the website will be included in the trial. Participants will be provided an honorarium of $20 for completing each follow-up questionnaire and an honorarium of $10 for initially accessing the study website (the latter will be employed in order to avoid loss of potential participants at this point). Potential participants deemed ineligible to participate will be compensated $20 for having completed the baseline questionnaire. See Figure 1 for a Consort Diagram summarizing this trial design.Figure 1
