Background: To simplify the screening process to identify problem drinking, researchers have developed single-item, quantity-based instruments. Quantity-based items, however, suffer from several limitations. Therefore, we sought to determine whether a non-quantity-based single item assessing drunkenness would be able to identify those who exhibited signs of hazardous alcohol use, as determined by AUDIT-C scores.

Methods: Between September and November of 2011, the alcohol-related behaviors of 1,062 self-identified current drinkers were assessed with self-report measures (i.e., AUDIT-C, and one item assessing frequency of drunkenness) in addition to corresponding biologic samples (i.e., BrAC samples). We assessed the concurrent validity of the single item to identify hazardous alcohol use established via gender-based AUDIT-C thresholds. Convergent validity of the single-item was assessed by determining its relationship to BrAC levels.

Results: The single item accounted for.791 of the area under the ROC curve for hazardous alcohol use (p < 0.001). When employing a cut-off of 1, the single-item question was 95.9% sensitive in identifying hazardous alcohol use.

Conclusion: The results reported herein highlight the validity (both concurrent and convergent) and potential utility of a non-quantity based single-item alcohol screen for assessing drunkenness. Overall, the benefits of this single item include (a) ease of implementation, (b) ease of interpretation (i.e., no need to perform mathematics in order to score), (c) brevity, and (d) overall ability to accurately detect hazardous drinking. Additional research is warranted to confirm the utility of this one-item drunkenness measure to capture risk of injury and hazardous drinking.
