Take the following as truth: The American Psychiatric Association in DSM III-R, IV2 and the World Health Organization (WHO) in the 9th and 10th International Classification of Diseases (ICD-9, -10) have rigorously defined alcohol abuse and alcohol dependence.
Then the following statement: "The WHO has a strict definition for alcohol abuse, which is more than four drinks a day, three times a week." is true, false, or inconclusive?
