We investigated if the dual systems model could explain the increased rates of substance use among at‐risk youth. This study sampled 365 adolescents, 289 of which had a family history of substance use disorder, assessed biannually between the ages 13–16 years old. Growth curve analyses revealed that higher levels of impulsivity were related to higher levels of sensation seeking and a slower rate of decline in impulsivity was related to a faster rate of increase in sensation seeking. Only family history status and sensation seeking were directly associated with substance use (marijuana, alcohol) at age 16, though family history status was also indirectly related to substance use through higher levels of impulsivity to higher levels of sensation seeking.

冲动和感觉寻求的发展：与高危青少年物质使用的关联。

我们调查了双系统模型是否可以解释高危青少年中药物使用率的增加。这项研究对 365 名青少年进行了抽样，其中 289 名有物质使用障碍的家族史，每两年评估一次，年龄在 13-16 岁之间。增长曲线分析显示，较高水平的冲动与较高水平的感觉寻求相关，而冲动下降速度较慢与感觉寻求增加速度较快有关。只有家族史状态和感觉寻求与 16 岁时的物质使用（大麻、酒精）直接相关，尽管家族史状态也通过更高水平的冲动性和更高水平的感觉寻求与物质使用间接相关。
