压力性生活事件对青少年烟酒使用的影响:有调节的中介模型

Stressful Life Events and Adolescent Tobacco and Alcohol Use: A Moderated Mediating Model

目的:探讨坚毅在压力性生活事件对青少年烟酒使用影响中的中介效应,以及亲子关系在其中的调节效应。方法:采用压力性生活事件问卷、坚毅问卷、亲子关系问卷和烟酒使用问卷对612名青少年进行调查。结果:(1)坚毅在压力性生活事件与青少年烟酒使用之间起到中介作用。(2)坚毅对青少年烟酒使用的影响受到亲子关系的调节作用,即低亲子关系下,高坚毅者要比低坚毅者更少使用烟酒。结论:压力性生活事件不仅直接影响青少年的烟酒使用还可以通过坚毅间接影响青少年的烟酒使用;亲子关系可以调节坚毅对青少年的烟酒使用的影响。

Objective： To examine whether grit played a mediation role in the association between stressful life events and adolescent tobacco and alcohol use, and whether parent-adolescent relationship moderated this mediating process.Methods： 612 adolescents participated in this study and completed four questionnaires, which included measures of stressful life events, adolescent tobacco and alcohol use, grit and parent-adolescent relationship. Results：（1）Grit mediated the relationship between stressful life events and adolescent tobacco and alcohol use;（2）Parent-adolescent relationship moderated the mediating path from grit to adolescent tobacco and alcohol use. Simple slope analysis indicated that the high grit was less likely to use alcohol and tobacco than those with low grit in the poor parent-adolescent relationship, but there was no significant difference in the healthy parent-adolescent relationship. Conclusion： Stressful life events have direct effects on adolescent tobacco and alcohol use and indirect effects through grit. Parent-adolescent relationship moderates the effect of grit on adolescent tobacco and alcohol use.
