Assuming a 28% chance for a child of a person with alcohol addiction to develop alcohol addiction themselves (based on the current population frequency of 7% for alcohol use disorders (National Institute of Alcohol Abuse and Alcoholism, 2015) and the reported four-fold increased risk for children of (Russell, 1990)
