Article Synopsis
- - The study evaluated the digital version of the Alcohol Use Disorders Identification Test (d-AUDIT) for effectively screening excessive alcohol consumption in primary care settings in Santiago, Chile, using a sample of 330 adults who had consumed alcohol frequently over the past year.
- - The analysis revealed a reliable two-factor model for the d-AUDIT, with strong validity and a high correlation (0.74) between factors, indicating that it effectively measures different aspects of alcohol use disorders.
- - The d-AUDIT and Fast Alcohol Screening Test (FAST) showed excellent diagnostic accuracy in identifying problematic drinking, with AUC values of 0.94 and 0.92, respectively, and the FAST was able to distinguish between hazardous and problematic
Objective: To reanalyze a clinical trial on the effectiveness of a Brief Intervention (BI) delivered by non-professionals to reduce risky alcohol drinking. Our previous null-hypothesis test of the effects of the BI yielded a 'non-significant' p-value, yet remained uninformative. Here we use the Bayesian paradigm which allows for expressing the probability of different effect sizes to better inform public policy decisions.

We compared the efficacy of two AUDIT-linked interventions provided by HTs: an informative leaflet and a BI plus leaflet.
Methods: This is a parallel-group randomized controlled trial with 1:1 randomization.
Background: Harmful alcohol use is a leading cause of global disability and death. However, increased detection and brief intervention capacity of more severe alcohol use disorders has not been accompanied by increased availability of treatment services. Incorporating treatment for such disorders into primary care is of paramount importance for improving access and health outcomes.
