Quantity frequency (consumption index) versus "CAGE" in the detection of alcoholism
1Department of Psychiatry, Faculty of Medicine, National University of Malaysia, Jalan Raja Muda Abdul Aziz, Kuala Lumpur.
Abstract:
The aim of this study was to compare and validate two simple methods of detecting excessive alcohol drinkers in a Malaysian hospital population. All 621 patients in the Medical, Surgical and Orthopaedic units of the General Hospital Kuala Lumpur were screened with the "CAGE" Questionnaire (a four question screening test to discriminate excessive drinkers) and two questions on the frequency and quantity of drinking called the Consumption Index. All CAGE scores had poor agreement (K = 0.37 to K = 0.1) with a psychiatric diagnosis of alcohol abuse and dependence using DSM III diagnosis. Reasons why the Consumption Index is a better screening instrument than the CAGE are discussed.
