The answer of “Yes” accounts for one point and the answer of “No” accounts for zero point. The higher the score the greater suggestion of alcohol problems. If the patient scores a total of 2 points, he/she is considered clinically significant for alcoholism. (Williams, 2014). On the CAGE questionnaire, the final question regarding using alcohol as an eye-opener is considered the most important question. This question indicates that the patient is undergoing withdrawals in the mornings. The questionnaire may work better in a primary care setting versus a certain population that consists of heavy drinkers and college students. (Williams, 2014). The wording of the CAGE questionnaire could be a negative connation to patients.

One study was done in a Belgium primary care setting. The study looked at the comparison of the CAGE questionnaire with other blood parameters that may indicate alcoholism. The questionnaire had a sensitivity range between 68% to 93% of men that were studied. However, the women did not have a high sensitivity range and did not show a correlation (Williams, 2014). The CAGE questionnaire has also been compared to other alcohol screening questionnaires: FAST (Fast Alcohol Screening Test) and AUDIT (Alcohol Use Disorders Identification Test).
A study was done in the United Kingdom with a sample size of 2185 patients and found that the CAGE questionnaire had a sensitivity of 40% and a specificity of 98% compared to the AUDIT questionnaire. This study was done in the emergency room setting, which looked at hazardous drinkers instead of alcohol dependence (Williams, 2014). Another study was done on ten primary care looking at the sensitivity and specificity of the CAGE questionnaire in regards to alcohol abuse and dependence. The results yield a sensitivity of 0.87 in inpatients and in primary care patients a 0.71 sensitivity (Pilowsky & Wu,
