Background: The Beck's Depression Inventory (BDI) and Alcohol Use Disorder Identification Test (AUDIT) have been validated for use in the study of alcohol related psychiatric disorders in the developed world as well as in Western Nigeria, but not in the Niger Delta Region. Aim: To ascertain the psychometric properties of BDI and AUDIT for use in this part of the world using psychiatric out-patients at the University of Port Harcourt Teaching Hospital. Methods: Four hundred and seventy (470) subjects were enlisted into the study using systematic sampling technique. The BDI and AUDIT were administered to each of them. One hundred and eighty five (185) subjects met the criteria for the second stage viz; a score of 18 and above on the BDI and/or a score of 5 and above on the AUDIT. Diagnoses of Depression and Alcohol Use Disorder were made using the Composite International Diagnostic Interview (CIDI). The data were analyzed using the statistical package for social sciences (SPSS) version 16.0 Results: The sensitivity and specificity of the BDI were 96.3% and 58.8% respectively. The positive and negative predictive values of BDI were 86% and 85.7% respectively. Also, the sensitivity and specificity of the AUDIT were 100% and 92.1%. Furthermore, the positive and negative predictive values of the AUDIT were 85.5% and 100% respectively. Conclusion: The BDI and AUDIT have excellent psychometric properties; hence they are valid for carrying out studies on alcohol related psychiatric disorders.
