Previous studies have identified an association between depressive mood and marijuana use. We examined adolescent self-control as a predictor of membership in joint developmental trajectories of depressive mood and marijuana use from adolescence to young adulthood. Urban African Americans and Puerto Ricans (N = 838) were sampled when participants were on average 14, 19, 24, and 29 years old. Using growth mixture modeling, four joint trajectory groups of depressive mood and marijuana use were established: low marijuana use/low depressive mood, low marijuana use/intermediate depressive mood, high marijuana use/low depressive mood, and high marijuana use/high depressive mood. Weighted logistic regression analysis showed that self-control at age 14 distinguished the high marijuana use/high depressive mood group and the low marijuana use/low depressive mood group from each of the other groups. Findings show that the co-occurrence of high levels of marijuana use and depressive mood from adolescence into young adulthood is predicted by low levels of self-control in adolescence. On the other hand, high selfcontrol is associated with low marijuana use and low levels of depression over time. Thus, while deficits in self-control in adolescence constitute a significant risk for maladjustment over time, high self-control exerts a protective factor with regard to marijuana use and depressive mood into young adulthood.
先前的研究已经确定了抑郁情绪与大麻使用之间的关联。我们将青少年自我控制能力作为从青春期到青年期抑郁情绪和大麻使用联合发展轨迹成员身份的预测指标进行了研究。当参与者平均年龄为14岁、19岁、24岁和29岁时，对城市非裔美国人和波多黎各人（N = 838）进行了抽样。使用增长混合模型，建立了抑郁情绪和大麻使用的四个联合轨迹组：低大麻使用/低抑郁情绪、低大麻使用/中度抑郁情绪、高大麻使用/低抑郁情绪和高大麻使用/高抑郁情绪。加权逻辑回归分析表明，14岁时的自我控制能力将高大麻使用/高抑郁情绪组和低大麻使用/低抑郁情绪组与其他组区分开来。研究结果表明，从青春期到青年期，大麻高使用量和抑郁情绪同时出现是由青少年时期低水平的自我控制能力所预测的。另一方面，随着时间的推移，高自我控制能力与低大麻使用量和低抑郁水平相关。因此，虽然青少年时期自我控制能力的缺陷会随着时间的推移构成适应不良的重大风险，但高自我控制能力在青年期对大麻使用和抑郁情绪起到了保护作用。
