Abstract summary 

No validated tools exist to screen for substance use or dependence in Mozambique. The aim of this study was to validate the Alcohol Use Disorder Identification Test (AUDIT) for use in primary care settings in Mozambique.The study administered a final adapted Mozambican 10-item AUDIT (AUDIT-10-MZ) to 502 individuals from antenatal, postpartum, and general outpatient consultations in three Ministry of Health primary health care clinics in Sofala Province, Mozambique. The study evaluated the AUDIT-10-MZ against the MINI 5.0-MZ as a gold standard diagnostic tool.Using the MINI 5.0-MZ, 16 (3.2%) of the sample tested positive for alcohol dependence and 3 (0.6%) tested positive for harmful alcohol use. The full AUDIT-10-MZ had acceptable internal consistency (α = 0.74); however, the shorter AUDIT-C-MZ had a higher alpha value than the full AUDIT screener (α = 0.79). The AUDIT-10-MZ performed well for screening in primary care, achieving areas under the receiver operating characteristic curves (AUROCs) of 0.94 (95% CI: 0.91, 0.96) for alcohol dependence. The AUDIT-C-MZ also performed well with an AUROC of 0.88 (95% CI: 0.80, 0.96) for alcohol dependence. Using a cut-off of ≥6, the AUDIT-10-MZ achieved a sensitivity of 68.8% and specificity of 92.0% for screening for alcohol dependence; a cut-off of ≥3 for the AUDIT-C-MZ achieved a sensitivity of 56.3% and specificity of 90.7%.Both the AUDIT-10-MZ and AUDIT-C-MZ are valid instruments for screening for alcohol dependence in Mozambique. The AUDIT-C-MZ performed particularly well and providers could use it as a brief screener in primary care settings. Optimal cut-points will depend on weighing false positives and false negatives but could be employed at ≥ 6 or ≥ 7 for the AUDIT-10-MZ and at ≥ 2 or ≥ 3 for the AUDIT-C-MZ. Future implementation research is needed to examine how best to integrate screening for substance use or dependence in primary care settings in Mozambique and other similar LMICs.
