This study examined the association between dimensions of personality problems (negative affectivity, detachment, antagonism, disinhibition, and psychoticism) and alcohol and substance use problems in emerging adults. The sample of 169 participants was used for data analysis. Participants were recruited online via MTurk and a student research participant pool. We found that there is a correlation between the overall personality dysfunction and alcohol and substance use problems. However, only disinhibition, detachment, antagonism, and psychoticism were correlated with alcohol and substance use problems. Multiple regression was used to compare the relative strength of association of variables correlated with alcohol and substance use problems, and it was found that disinhibition and antagonism remained significant predictors of alcohol and substance use problems while controlling for all five personality dimensions. We also found that hostility and paranoia were correlated with alcohol and substance use problems. In our last hierarchical regression analysis, we found that only Psychoticism, Hostility, Paranoia, and Self-Depreciation remained significant predictors of alcohol and substance use.
