Influence of Personality Traits on the Severity of Alcohol Use Disorders

Alcohol Use Disorders (AUD) are the most prevalent psychiatric diagnosis in the general population. The study of personality characteristics, using Cloninger Personality Inventory (TCI-R), allows us to know the evolution of these patients at the beginning of treatment.

We conducted a cross-sectional, observational and descriptive study for 3 years with a total of 304 patients. We studied the severity of their alcohol disorder by the Alcohol Dependency Intensity Scale (EIDA), Scale of Obsessive Consumption Compulsive (OCDS) and European version of the Addiction Severity Index (EUROPASI); we studied the relationship with the personality traits of TCI-R.

The personality lines influence the evolution of alcohol use disorder (AUD). People with higher scores on Reward Dependency (RD), Persistence (P), Cooperation (CO) and Autotranscendence (ST) have a better prognosis while people with higher scores on Search for Novelty (SN) and Avoidance of Damage (AD) have a worst prognosis. Women present differences in consumption in relation to men, as a consequence of their personality. Women have lower scores in Persistence (P) y Self-Transcendence (ST) which are associated with the greater severity of their addiction.
