Five-Factor Model personality profiles of drug users.

Area of Science:

• Psychology
• Psychiatry
• Public Health

Background:

• Personality traits are recognized as risk factors for substance use.
• Psychoactive substances can influence an individual's personality.
• Personalized treatment approaches for substance use disorders are gaining interest.

Purpose of the Study:

• To compare the personality profiles of users of tobacco, marijuana, cocaine, and heroin with non-users.
• To investigate the role of individual differences, specifically personality traits, in drug use patterns.
• To utilize the Five-Factor Model (FFM) of personality in a diverse community sample.

Main Methods:

• A diverse community sample (N = 1,102, mean age = 57) from the Epidemiologic Catchment Area (ECA) program in Baltimore, MD, USA.
• Assessment of personality traits using the Revised NEO Personality Inventory (NEO-PI-R).
• Evaluation of psychoactive substance use via systematic interviews.

Main Results:

• Cigarette smokers scored lower on Conscientiousness and higher on Neuroticism than never smokers.
• Cocaine/heroin users exhibited extreme scores in high Neuroticism (Vulnerability) and low Conscientiousness (Competence, Achievement-Striving, Deliberation).
• Marijuana users showed high Openness to Experience, average Neuroticism, and low Agreeableness and Conscientiousness.

Conclusions:

• The study confirms associations between drug use, high negative affect, and impulsive traits.
• A significant link between various forms of drug use and low Conscientiousness was highlighted.
• Findings offer insights into the etiology of drug use and inform public health interventions.
