Screening questionnaires for substance abuse post brain injury: a review

Objective: To assess the psychometric properties of the available assessment questionnaires for substance abuse studied within a brain injury population. Methods: A literature search was conducted on MEDLINE, PsycINFO, CINAHL, and Embase databases. Articles published in English from inception through March 2018 on the screening questionnaires used to identify substance abuse post brain injury were reviewed. Eligible primary studies had to include: adults (participants >= 18 years old) post brain injury; and report measures of diagnostic accuracy (e.g., sensitivity, specificity, and diagnostic odds ratio). Results: Six screening questionnaires were included: Alcohol Use Disorders Identification Test, Brief Michigan Alcohol Screening Test, CAGE, Drug Abuse Screening Test, Substance Abuse Screening Inventory and the Short Michigan Alcohol Screening Test (SMAST). All questionnaires, except the SMAST, used the Diagnostic and Statistical Manual of Mental Disorders as the criterion measure. While report measures of diagnostic accuracy were reported and summarized, none of the studies provided reliability information or subgroup analysis among those with brain injury. Conclusions: Concerns of social desirability, population demographics, responsiveness to treatment effects, and administrative burden are important when selecting a questionnaire. Research examining the reliability of substance abuse screening questionnaires in the brain injury population is lacking and future research is warranted.
