Which question is the best indicator of a potential alcohol-use disorder in a client?

The question about feeling guilty regarding drinking is a strong indicator of a potential alcohol-use disorder because it touches on the emotional and psychological aspects of alcohol consumption. Feelings of guilt are often associated with behaviors that an individual may recognize as problematic or excessive. This self-reflection can indicate a level of insight into their drinking habits and suggests that the individual may be experiencing negative consequences related to their alcohol use, which can be a critical warning sign of dependency or misuse.

In contrast, the other questions focus more on frequency or social contexts of drinking rather than the individual's emotional response to their alcohol consumption. Simply inquiring about the types of alcohol consumed, drinking patterns, or the age at which they began drinking does not provide insight into the potential for an alcohol-use disorder. These factors might indicate social habits but do not necessarily reflect the individual's relationship with alcohol or potential for problematic use.
