A review of performance indicators of single-item alcohol screening questions in clinical and population settings.

Screening and brief intervention (SBI) for unhealthy alcohol use is recommended as a routine clinical procedure for adults in primary care settings. However, implementation of SBI remains suboptimal, in part reflecting time constraints in clinical settings. Single Item Screening Questions (SISQ) have increasingly been studied as a means of minimizing assessment burden. Although the ability of SISQ to accurately detect unhealthy alcohol use (i.e., at-risk drinking or alcohol use disorder) has been studied in various clinical and population settings, results have not been summarized in aggregate. This descriptive summarizes SISQ performance metrics across various clinical settings and populations. Based on results from 40 identified studies, there is consistent support that SISQ have good sensitivity as screeners for unhealthy drinking, with performance generally being comparable to longer validated instruments. Collectively, these results justify further efforts to evaluate SISQ as a means of maximizing SBI uptake and efficiency in various clinical settings.
