Effectiveness of an Intervention to Reduce Driving Under the Influence of Alcohol Among Drivers

Objectives: The main objective of this pilot study is to assess the feasibility and effectiveness of a brief intervention to reduce drinking-driving behavior. Methods: Design: Pilot multicentre before/after intervention study without control group. Participants: We aim to recruit, from 01/01/2013 to 01/05/2013, 212 drivers aged 18 to 65 who declared to have consumed alcohol previous to driving, at least once in the past 30 days. Intervention: Brief behavioral intervention to reduce alcohol consumption before driving. Outcomes: Frequency of driving under the influence of alcohol in the past 30 days, regular alcohol consumption (Audit-C test), level of self-efficacy and stage of change according to the Prochaska and DiClemente's Transtheoretical Model of Change, sociodemographic variables, driver's profile, chronic pathologies, long -term medications, level of self risk perception. Information will be checked against medical record. Information on a) frequency of driving under the influence of alcohol in the past 30 days, b) regular alcohol and c) level of self-efficacy and stet of change according Prochaska State will be gathered at one month and 12 month post intervention. Descriptive bivariate analysis to assess the distribution of risk elements associated to drinking-driving behavior. Potential impact expected: This pilot project will determine the feasibility of making a brief advice intervention in drivers under the influence of alcohol in primary care.
