Answer

The sensitivity of the CAGE questionnaire was thought to be 75%. More recent studies, however, show that the sensitivity is lower, particularly in populations with a lower prevalence, such as among female and elderly populations. The CAGE questionnaire also may fail to identify binge drinkers and cannot identify those who have not experienced the consequences of alcoholism. Nevertheless, the CAGE questionnaire is brief and easy to administer
