The study was published today in the British Journal of General Practice.
GPs do not currently need to screen every patient for alcohol problems, the researchers say, but should they wish to do so many of the surveys available can be as long as ten questions.
Too large a questionnaire could be a long and drawn-out task to administer to each patient.
Instead, the scientists wanted to determine whether there is room for a shorter survey to be used more widely "without sacrificing accuracy."
If the two questions were used alone it correctly identified alcohol abuse in 87.2 per cent of cases as well as correctly identifying those who do not suffer with alcohol problems in 79.8 per cent of cases.
The extra four questions to maximise accuracy were part of the CAGE questionnaire, a "four-question survey widely used to screen for alcoholism," which was developed by John Ewing in 1984.
The Alcohol Use Disorders Identification Test (AUDIT) uses ten questions.
The implications of concluding that two questions is all that is needed to detect alcohol abuse in a significant portion of the population means that GPs may be able to screen for problems much easier and quicker than previously thought.
