Abstract

Background: Substance use is a leading cause of preventable morbidity and mortality worldwide. Population-wide screening for problematic substance use in primary health care may mitigate the serious health and socio-economic consequences of such use, but the standard Alcohol, Smoking and Substance Involvement Screening Test (ASSIST 3.1) may be too long for wide-scale screening. How well validated shorter versions (ASSIST-Lite, ASSIST-FC) perform in identifying those with ASSIST 3.1 problematic use in different settings is unclear.

Methods: General population Jewish adults in Israel (N = 2,474) responded to an online survey that included the ASSIST 3.1 and sociodemographics. Across substances (alcohol, tobacco, cannabis, sedatives, prescription stimulants, prescription painkillers), receiver operator characteristic curve analysis determined that ASSIST-FC scores performed better than ASSIST-Lite at identifying those with problematic use, and evaluated differential ASSIST-FC performance by gender or age. Test characteristics and agreement were evaluated for binary ASSIST-FC versions, with ASSIST 3.1 problematic use as the gold standard.

Results: ASSIST-FC scores showed high ability to identify ASSIST 3.1 problematic use, with minimal differences by gender or age. Binary ASSIST-FC (most substances: threshold 3+; alcohol: 5+) showed high specificity and positive predictive value, acceptable sensitivity, and good agreement.

Conclusions: The ASSIST-FC, which assesses frequency of use and other's concerns about use, appears useful for very brief screening in primary care to identify patients who may benefit from intervention. Early identification of those at-risk may prevent more severe consequences and ultimately decrease the significant costs of problematic substance use on the individual and population level.
