Tehran University of Medical Sciences Iranian Journal of Public Health 2251-6085 38 3 2009 09 15 113 117 Y Zargar M Ghaffari 2015 10 03 Background: This study aimed at investigating the simple and multiple relationships between   personality traits and addic­tion potential in university students. Methods: 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. Results: There were simple and multiple relationships between personality traits and addiction potential. Multiple regres­sion analysis (stepwise method) showed that neuroticism, conscientiousness and agreeableness had significant multiple correla­tion with addiction potential (F=32.89, P<0.001). The components of openness and extroversion eli-minated from regres­sion. Conclusion: Personality traits predicted addiction potential in university students. The most important suggestion of this re­search was to pay attention scientifically to personality characters as a fundamental factor of this difficulty, rather than just empha­sizing on the cessation of drug or alcohol using. https://ijph.tums.ac.ir/index.php/ijph/article/view/3180 https://ijph.tums.ac.ir/index.php/ijph/article/download/3180/2979
