To examine the influence of childhood economic strains on substance use in young adulthood and to assess the mediating roles of self-control as well as positive parenting during adolescence in a nationally representative longitudinal cohort.
The study included data from participants (n = 1,285) in the Panel Study of Income Dynamics, Child Development Supplement, and Transition to Adult. Structural equation modeling was used to evaluate the associations among risk factors during childhood and adolescence that predicted substance use in early adulthood.
Conditions of economic strains, especially poverty, during childhood were associated with an increased likelihood of regular smoking in adulthood, which was partially mediated by poorer self-control during adolescence.
Self-control is negatively affected by economic strains and serves as a mediator between poverty and risk of regular smoking. Additional research is needed to better understand how economic strains effect the development of self-control.
探讨儿童期经济压力对青年期物质使用的影响,并在全国代表性纵向队列中评估青少年时期自我控制和积极养育的中介作用。
本研究纳入了来自收入动态面板研究、儿童发展补充调查和向成人过渡的参与者(n=1285)的数据。结构方程模型用于评估儿童期和青少年期风险因素与成年早期物质使用之间的关联。
儿童期的经济压力状况,尤其是贫困,与成年后经常吸烟的可能性增加有关,而这种关联部分是由青少年时期较差的自我控制所介导的。
自我控制受到经济压力的负面影响,并在贫困和经常吸烟风险之间起中介作用。需要进一步的研究来更好地理解经济压力如何影响自我控制的发展。
