Research conducted via the Internet has the potential to reach important clinical populations of participants who would not participate in traditional studies. Concerns exist, however, about the validity of samples recruited in this manner, especially when participants are anonymous and never have contact with study staff. This study evaluated two anonymous samples that were recruited over the Internet to test an online program designed to help problem drinkers. The two studies were conducted 3 years apart, and different recruitment strategies were utilized. Despite these differences, the two samples were highly similar in demographic and clinical features. Correlations that have been …

Most individuals with drinking problems do not receive treatment, generally because they do not perceive the need for it. It is difficult to access this population of problem drinkers in order to encourage treatment-seeking. A Web-based program was written, designed to increase motivation for change. The program guided non-treatment-seekers through a multi-stage assessment and provided them with feedback. The level of interest in treatment was measured pre-and post-intervention. Compared to baseline, after the intervention, significantly more individuals rated themselves "very interested" in participating in some form of traditional treatment (19% vs. 28%), and their focus on a specific modality increased.

OBJECTIVE: The most common obstacle to the treatment of individuals with drinking problems is that most do not seek treatment. This study compared a group of treatment-seeking patients with users of an alcohol-evaluation Web site to determine whether an Internet application could reach a population of problem drinkers who are distinct from those served by currently available forms of care.
METHODS: An open-source application was developed that was modeled on the Drinker's Check-Up, which has been shown to increase motivation for behavior change while presenting itself as a nonthreatening evaluation. To recruit non-treatment seekers, the program was offered as a …
