Highly endorsed screening and assessment scales for alcohol problems: A systematic review

Abstract

Background: Problems associated with alcohol use are multidimensional with psychiatric, psychological, physical, and social aspects, which makes it challenging to choose appropriate assessment scales. However, there has been no systematic evaluation of existing alcohol scales. Methods: A systematic literature search was conducted for articles that assessed the psychometric properties of scales for alcohol use disorder on March 19, 2023, using Medline, EMBASE, and PsycINFO. Only scales whose original development papers were cited more than 20 times were included. The methodological quality and psychometric properties of the scales were evaluated using COnsensus-based Standards for the selection of health Measurement INstruments. The overall rating of the scales were assessed with a score ranging from 0 to 18. Results: In total, 314 studies and 40 scales were identified. These scales differ widely in measurement methods, target populations, and psychometric properties. The overall mean score was 6.3, and only the following three scales received >9 points suggesting a moderate level of evidence: Alcohol Use Disorders Identification Test (AUDIT), Alcohol Dependence Scale (ADS), and Short Alcohol Dependence Data Questionnaire (SADD). Measurement error and responsiveness were not evaluated or reported in the included scales. Conclusions: Although the AUDIT, ADS, and SADD were rated the highest among the 40 scales, they showed, at most, a moderate level of evidence. These findings underscore the need to accumulate further evidence to assure the quality of the scales. It may be advisable to select and combine scales to meet the purpose of the assessment.
