The purpose of this study is to investigate the role of attitude to substance in the relationship between self-efficacy and adolescents' preparedness of addiction.<br /> Method: The present study is descriptive-correlational performed on 228 high school students (116 girls, 112 boys) in Lorestan province, who are selected by multi-stage cluster sampling. Data collection tools are Rahmati Attitude to Substance Questionnaire (ASQ), Muris Self-efficacy Questionnaire-Children (SEQ-C), and Zargar Iranian Addiction Potential Scale (IAPS). Data are analyzed using Pearson correlation and multiple regression analysis in SPSS software version 22.<br /> Results: The results show that there are significant correlations between attitude to substance, self-efficacy and addiction preparedness (P < 0.05). Also, the results of hierarchical regression analysis indicate that attitude toward substance can moderate the relationship between self-efficacy and addiction preparedness (P < 0.05).<br /> Conclusion: The results of this study indicate that the attitude toward substance can moderate the relationship between self-efficacy and addiction preparedness. Consequently, changing the attitude of individuals to substance can reduce the tendency of adolescents to consume drugs. https://www.behavsci.ir/article_103840_ddfd4de1ed41cfb2a723a4264e8c97d4.pdf
