Therefore, the present study investigated in frame of a model the moderator role of conscientiousness in related to effect of socioeconomic status, neuroticism, extraversion, openness to experience, and agreeableness on Substance, Alcohol, and tobacco Use. Materials and methods: Current study is analytical- cross sectional and regarding to data gathering and analysis methods was conducted in correlational way. The number of 300 (124 mal and 176 female) students were selected through available sampling from Kharazmi university and were assessed employing NEO Personality Questionnaire and researcher made Questionnaires on socioeconomic status and substance use.

Results: Result showed that conscientiousness had significant positive relationship with extraversion (r=0.46, P<0.01), openness to experience (r=0.14, P<0.05), and agreeableness (r=0.20, P<0.01), and significant negative relationship with neuroticism (r=-0.35, P<0.01), socioeconomic status (r=-0.18, P<0.01), and substance use (r=- 0.17, P<0.01). Moreover, sugested model for investigating the moderator role of conscientiousness in related to effect of socioeconomic status, neuroticism, extraversion, openness to experience, and agreeableness on substance use had excellent fitness (RMSEA=0.04, CFI=0.99, NFI=0.99, GFI=0.99, AGFI=0.96) with data. Conclusion: The findings showed that personality traits and socioeconomic status, either directly or indirectly, affected the substance use.
