[Big five-factor contributions to addiction to alcohol]

Personality in the field of addiction has been the subject of many studies. The purpose of this article is to synthesize the data obtained with the Neuroticism Extraversion Openness - Personality Inventory - Revised (NEO-PI-R) and the NEO - Five-Factor Inventory (NEO-FFI) among the persons who drink and suffer from addiction to alcohol.

These tools, based on the theory of "The Big Five Factors", assess the personality from a dimensional point of view. The five big dimensions addressed by these tools, are "Neuroticism" (general tendency to experience negative feelings), "Extraversion" (sociability, positive feelings, activity and self-confidence), "Openness" (imagination, intellectual curiosity, aesthetic sensitivity, attention paid to one's own feelings and no dogmatic behavior), "Agreeableness" (interpersonal tendencies) and "Conscientiousness" (forward planning, organization and task carrying out). According to Diagnostic and Statistical Manual of mental disorders (DSM-IV-TR), alcohol consumption is based on three dissimilar behaviors: utilization (alcohol consumption not leading to complications or damage), abuse (regular consumption likely to cause somatic, psycho-emotional or social damage for the individual or for his/her family circle) and dependency (excessive utilization leading to deterioration in functioning or clinically significant suffering).

Alcohol consumption among young adults can thus be predicted through a high level of "Neuroticism" associated with a low level of "Agreeableness". Persons having been addicted to alcohol (present or past) have a high level of "Neuroticism", a low "Agreeableness" and a low level of "Conscientiousness", contrary to patients who have never been addicted to alcohol. The NEO-PI-R also enables a more accurate analysis of the personality, since each of these five big dimensions is divided into six facets. Among the patients with a past or present diagnosis of alcohol abuse, we found a low score on facets "trust", "achievement striving", "self-discipline" and "dutifulness" and a high score on "impulsiveness", "vulnerability", and "excitement-seeking". Although dimension and facet results measured by this tool can differ according to craving level or according to gender, the studies agree in that there are common aspects among the patients.
