Vida PURA: results from a pilot randomized trial of a culturally adapted screening and brief intervention to reduce unhealthy alcohol use among Latino day laborers

Abstract

Latino immigrant men are at increased risk for unhealthy alcohol use. Vida PURA is a culturally adapted evidence-based intervention that consists of promotores providing screening and brief intervention to reduce unhealthy alcohol use among Latino immigrant men. The purpose was to assess the efficacy of Vida PURA in a pilot randomized control trial. Participants were screened for eligibility at a day labor worker center using the Alcohol Use Disorders Identification Test (AUDIT). Those with an AUDIT score ≥ 6 (N = 121) were randomized into an intervention (N = 77) or control group (N = 44). Participants in the intervention group received a brief intervention from a promotor including personalized feedback, motivational interviewing to assess their readiness to change, and referral to services. Participants in the control group received information about local substance use treatment services. We assessed changes in AUDIT scores, drinks per drinking day, drinking days, and frequency of heavy episodic drinking at 2 and 8 weeks following the baseline survey using a mixed-effects regression model. Many men had high AUDIT scores, indicating dependence. Both the intervention and control groups reduced their alcohol-related behaviors over time, but there were no significant differences between the groups. A culturally adapted brief intervention may not be enough to significantly reduce alcohol use among Latino day laborers, especially among those that are dependent. We discuss lessons learned from this trial, including the value of community-based approaches to reaching high-risk and underserved populations.
