What is the name of the self-report screening instrument that consists of 4 yes/no questions and takes approximately 1 minute to complete?

The CAGE questionnaire is a brief self-report screening tool specifically designed to identify potential problems related to alcohol use. It consists of four simple yes/no questions that are focused on the individual's drinking behavior and its consequences. This succinct format allows for quick administration, taking approximately one minute to complete, making it highly efficient for initial screenings in various settings, including primary care and counseling.

The CAGE questionnaire is effective because it addresses key areas that can indicate alcohol dependence, such as the need to cut down on drinking, annoyance by criticism, guilt about drinking, and the use of alcohol as an eye-opener. Its simplicity and focus on essential aspects of alcohol use make it a widely used tool in both clinical and non-clinical environments. Other screening instruments may have different structures, lengths, or focus areas, which is why they do not match the description of being both succinct and consisting of just four questions as the CAGE does.
