Alcohol risk-reduction skills training in a national fraternity: a randomized intervention trial with longitudinal intent-to-treat analysis.

Objective: The potential effectiveness of two group-administered social-skills training interventions for reducing high-risk drinking behavior was evaluated through a prospective randomized intervention trial with 3,406 members of a national college fraternity.

Method: Ninety eight of 99 chapters of a national fraternity were randomly assigned, within three strata, to receive (1) a 3-hour baseline intervention, (2) the same baseline intervention plus two booster sessions, or (3) assessments only. The current article emphasizes a rigorous intent-to-treat analysis model that compares outcomes among members assigned to receive study interventions (vs assessment-only sites) regardless of whether they actually did receive them; it also includes individuals at intervention sites even if they did not participate.

High-risk drinking among college fraternity members: a national perspective.

This survey, with its 85% response rate, provides an extensive profile of drinking behaviors and predictors of drinking among 3,406 members of one national college fraternity, distributed across 98 chapters in 32 states. Multiple indexes of alcohol consumption measured frequency, quantity, estimated blood alcohol concentration levels (BACs), and related problems. Among all members, 97% were drinkers, 86% binge drinkers, and 64% frequent binge drinkers.

Examining the effects of a national alcohol-free fraternity housing policy.

This investigation examined the effectiveness of an alcohol-free fraternity housing policy on the risky alcohol use of members of a national fraternity (N=718). Comparisons of members in chapters with fraternity housing (FH) and those in chapters without housing (NFH) over time revealed no policy-related effects on measures of alcohol use. Among FH members, comparisons of those who lived in fraternity housing and those who lived in other housing also found no effects.
