The present study examined the relationship between substance use and reasoning in adolescents, and further investigated the modulation role of growth mindset on this relationship. A total of 1759 adolescents in China with substance use experience were investigated. The results showed that substance use (smoking, drinking, and illicit drug use) was negatively correlated with reasoning ( = -0.24 ∼-0.39, < 0.01) and growth mindset ( = -0.18 ∼-0.32, < 0.01). Regression analysis revealed that after controlling for the background variables (i.e., age, family annual income, and parents' educational level), only illicit drug use was the significant predictor of reasoning (β = -0.325, = -14.28, < 0.001). The interaction effect between growth mindset and illicit drug use was also a significant predictor of reasoning (β = -0.067, = -2.92, = 0.004), indicating growth mindset modulated the relationship between illicit drug use and reasoning ability. Further analysis found that the negative correlation between frequency of illicit drug use and reasoning in high growth mindset group was weaker than that of low growth mindset group ( = 332.51, < 0.001, = 0.22). This suggests that growth mindset plays a significant moderating role in the relationship between substance use and reasoning. Overall, substance use has adverse effect on adolescent reasoning, however, growth mindset could reduce this adverse effect.
本研究考察了青少年物质使用与推理之间的关系，并进一步探究了成长型思维模式对这种关系的调节作用。对中国1759名有物质使用经历的青少年进行了调查。结果显示，物质使用（吸烟、饮酒和非法药物使用）与推理（=-0.24～-0.39，<0.01）以及成长型思维模式（=-0.18～-0.32，<0.01）呈负相关。回归分析表明，在控制背景变量（即年龄、家庭年收入和父母教育水平）后，只有非法药物使用是推理的显著预测因素（β=-0.325，=-14.28，<0.001）。成长型思维模式与非法药物使用之间的交互作用也是推理的显著预测因素（β=-0.067，=-2.92，=0.004），表明成长型思维模式调节了非法药物使用与推理能力之间的关系。进一步分析发现，高成长型思维模式组中非法药物使用频率与推理之间的负相关比低成长型思维模式组弱（=332.51，<0.001，=0.22）。这表明成长型思维模式在物质使用与推理之间的关系中起显著的调节作用。总体而言，物质使用对青少年推理有不利影响，然而，成长型思维模式可以减轻这种不利影响。
