Simple and Multiple Relationships between Big-Five Personality Dimensions and Addiction in University Students

This study aimed at investigating the simple and multiple relationships between personality traits and addic tion potential in university students. Three hundred and forty two students were selected by cluster sampling from the Shahid Chamran University (Iran). The scales used for this descriptive study were NEO-FFI personality inventory and Iranian Addiction Potential Scale (IAPS). To analyze the data, we used descriptive and inferential statistic test via spss-13. There were simple and multiple relationships between personality traits and addiction potential. Multiple regres sion analysis (stepwise method) showed that neuroticism, conscientiousness and agreeableness had significant multiple correla tion with addiction potential (F=32.89, P< 0.001). The components of openness and extroversion eliminated from regres sion. Personality traits predicted addiction potential in university students. The most important suggestion of this re search was to pay attention scientifically to personality characters as a fundamental factor of this difficulty, rather than just empha sizing on the cessation of drug or alcohol using.
