Aims: Although National Alcohol Screening Day (NASD) became the USA's largest and most visible community-based intervention targeting risky drinking over the past decade, its utility in identifying individuals who are at risk for alcohol problems and in catalyzing behaviour change has not been tested in studies including untreated controls. The purpose of this study was to assess changes in alcohol use three months following NASD participation using a quasi-experimental pretest-posttest control group design.
Methods: Participants (N = 713) were recruited from 5 NASD sites in Florida, Massachusetts, and New York, USA.
Objective: The authors evaluated the efficacy of the 2002 college-based National Alcohol Screening Day (NASD) by determining: (1) the demographic and clinical characteristics of the participants that were screened and (2) the degree to which those scoring at hazardous drinking levels received clinical intervention or were referred for further assessment or treatment.
Participants: Of 45,368 participants, 23,334 were screened and 14,598 received some form of clinical intervention, defined as advice or referral.
Methods: The authors conducted nonparametric and univariate analyses to test for statistical differences in demographics, clinical-characteristics, and interventions-as a function of-screening mode.
