Drug dealers may be at increased risk for drug use. However, there is a dearth of research focused on how these relationships develop across time. Group-based trajectory modeling (GBTM) was used to assess heterogeneity in the development of drug dealing behavior. Line graphs modeling the average frequency of use of drugs across time based on trajectory membership described drug use patterns. T-tests were used to test for significant differences between drug use patterns. Results indicated that a four-group model of drug dealing best fit the data. Changes in each type of drug use corresponded strongly with changes in drug dealing behaviors.

养成习惯？少年犯青少年毒品交易纵向模式与吸毒轨迹的关系

毒贩可能面临更大的吸毒风险。然而，缺乏关于这些关系如何随时间发展的研究。基于组的轨迹建模 (GBTM) 用于评估毒品交易行为发展的异质性。基于轨迹成员描述的药物使用模式，对跨时间平均药物使用频率进行建模的折线图。T检验用于检验药物使用模式之间的显着差异。结果表明，毒品交易的四组模型最适合数据。每种毒品使用类型的变化与毒品交易行为的变化密切相关。
