The temperament at the age of 4 of 122 Swedish men was determined by a psychologist and their alcohol consumptions at ages of 18, 25 and 36 were measured. There were five kinds of temperaments: independent/goal-oriented, persistent/goal-oriented, extravert/aggressive, extravert/outgoing and socially reactive. The study shows that the "persistents" (at the age of 4) had the lowest rate of alcohol-related crimes when adults. "Aggressives" were likely to be binge-drinkers at the age of 25. "Extravert/outgoing" people (social confidence, activity, seek attention of adults, untidy -- when they were 4) were the most likely to be in trouble because of alcohol. "Socially reactive" men had few alcohol-related problems. Rothbart and Ahadi as well as Caspi found the same kind of correlation between "extravert/outgoing" and alcohol.
Results are marginally meaningful though, it would be hazardous to draw conclusions before the study can be reproduced on a larger population.

What is the boundary between "hard" drinking and alcoholism? Is alcoholism the main threat from alcohol?
Most social problems due to alcohol are not from alcoholics but by other "hazardous drinkers". These people drink between 30 and 50 drinks a week and generally do not consider that they have a drinking problem. According to experts, 1 in 13 men is dependent on alcohol (this is a British figure but we can guess it will not be dramatically lower in other countries.) These men will not all be considered alcoholics and treated as such.
It has been established that drivers arrested intoxicated at the wheel who took "classes" about alcohol have a lower reconviction rate than those who did not take them.

Authors identified two types of alcoholism. They describe the effects and causes (heredity or environment) as shown in the table below. They studied adoptees whose biological parents were known and they looked for correlations between alcoholism of the children and alcoholism of the biological or adoptive parents.
| Type I | Type II | |
| Cause | genetic and environnement | mostly genetic |
| Gender | men and women | men more than women |
| Began | after 25 years of age | before 25 years of age |
| Alcohol-related issues |
|
|
| Personality traits | weak search of novelty | strong search of novelty |
| Reason for drinking | anxiety | euphoria |

"Recent years have seen numerous studies dedicated to risk factors of alcohol abuse. But insufficient attention has been paid to the 'beneficial factors' that in any society play a self-regulating role in the use and the abuse of alcohol. [...] Recent research conducted by experts in the Osservatorio [Osservatorio Permanente sui Giovani e l'Alcool in Rome] shows that the use of alcohol among young persons is very much conditioned by their cultural environment, by their socio-economic organisation and by the symbolic imports of the different types of alcoholic products, referring to cultural models."
