Stimulant/amphetamine use presents a major public health problem. There is a dearth of research which has studied this behavior from a dual systems model perspective. This study examined the relevance of sensation-seeking and impulse control for predicting stimulant/amphetamine use and tested whether these relationships varied as a function of time. The Pathways to Desistance data were used in analyses, comprising the responses of 1,354 justice-involved youth across 84 months with 11 data points each. Mixed effects modeling was used to examine these relationships. Results indicated that greater sensation-seeking was associated with greater odds of stimulant/amphetamine use. This relationship varied as a linear function of time, with the salience of sensation-seeking for predicting stimulant/amphetamine use declining as participants got older. However, this interaction only reached marginal significance at the p < .09 level. Interventions focused on sensation-seeking may help reduce stimulant/amphetamine use, but effects may be greater for adolescents relative to young adults.

兴奋剂/苯丙胺的使用是一个主要的公共卫生问题。缺乏从双系统模型角度研究这种行为的研究。这项研究检查了感觉寻求和冲动控制与预测兴奋剂/苯丙胺使用的相关性，并测试了这些关系是否随时间而变化。在分析中使用了 Pathways to Desistance 数据，其中包括 84 个月内 1,​​354 名参与正义的青年的反应，每人有 11 个数据点。混合效应模型用于检查这些关系。结果表明，更多的感觉寻求与使用兴奋剂/苯丙胺的几率更大有关。这种关系作为时间的线性函数而变化，随着参与者年龄的增长，用于预测兴奋剂/苯丙胺使用的感觉寻求的显着性下降。p  < .09 水平。专注于寻求感觉的干预措施可能有助于减少兴奋剂/苯丙胺的使用，但与年轻人相比，对青少年的影响可能更大。
