Material and Method: The participants were recruited via interview using the alcohol section of the Thai version of Diagnostic Interview for Genetic Studies (Th-DIGS), which included 165 psychiatric outpatients with alcohol dependence and 165 psychiatric outpatients without alcohol-related disorders. The validity of diagnoses provided by psychiatrists and physicians (in the records) compared with the Th-DIGS diagnoses were analyzed. Kappa statistics were applied to compare the agreement of the responses for the written version and the oral CAGE interviews.
Results: Compared with the diagnoses using Th-DIGS, the physician specificity and positive predictive value were 100% (95% CI: 97.8-100% and 94.9-100%, respectively). However, the sensitivity and negative predictive value were 43% (95% CI: 35.4-51%) and 63.5% (95% CI: 57.5-69.6%), respectively. The Kappa value for the written version of the CAGE questionnaire and the CAGE oral interview was 0.723.
Conclusion: The results of the present study suggest the need to increase physician awareness regarding alcohol-related problems. A brief and high-sensitivity screening questionnaire, such as the CAGE questionnaire, written versions and oral interview, can be implemented for screening alcohol-related disorders in a clinical setting.
