青少年时期是冒险行为频发的时期，而冒险行为很可能会给青少年自身乃至整个社会带来消极影响。青少年的冒险行为受诸多因素综合影响，本研究将重点关注于家庭环境中的家庭经济压力对青少年冒险行为的影响。同时，研究也讨论了自我控制在家庭经济压力和冒险行为之间的中介作用，以及该中介效应是否在不同性别群体中存在差异。

本研究以贵州省毕节市某县一所中学七年级学生共495名以及其家长共401名作为被试，通过青少年与家长报告的收集了青少年的家庭经济压力、自我控制能力和冒险行为水平，以检验自我控制在家庭经济压力影响青少年冒险行为路径中的中介作用，以及该中介作用的性别差异。

研究结果显示：（1）家庭经济压力对青少年冒险行为无直接预测作用；（2）自我控制在家庭经济压力对青少年冒险行为的影响中发挥着完全中介作用。具体而言，家庭经济压力通过减弱青少年的自我控制能力促进其冒险行为的发生。（2）自我控制的中介作用在男女生群体中存在差异，其主要表现为，在男生群体中，自我控制的中介作用显著。但在女生中未能发现显著的中介效应。

该结果为家庭经济压力影响冒险行为的机制提供了一种解释路径，并为干预青少年冒险行为提供了重要的实践指导依据。

Adolescence is a period of frequent risk-taking behavior, and risk-taking behavior is likely to have a negative impact on teenagers themselves and even the whole society. Teenagers' risk-taking behavior is affected by many factors. This study will focus on the impact of family economic pressure in the family environment on teenagers' risk-taking behavior. At the same time, the study also discusses the intermediary role of self-control between family economic stress and risk-taking behavior, and whether the intermediary effect is different in different gender groups.

In this study, the researchers selected 495 seventh-grade students and 401 parents from a middle school in Guizhou Province as subjects. Through the reports of adolescents and parents, the family economic strain, self-control ability and risk-taking behaviors were collected to test the intermediary mechanism and gender differences of self-control between family economic stress and adolescent risk-taking behavior.

The results show that: (1) family economic stress has no direct predictive effect on teenagers' positive and negative risk-taking behavior; (2) self-control plays a complete intermediary role in the influence of family economic stress on teenagers' positive and negative risk-taking behavior. Specifically, family economic pressure promotes the occurrence of positive and negative risk-taking behaviors by weakening teenagers' ability of self-control. (2) the mediating effect of self-control is different between male and female groups, which is mainly manifested in that the mediating effect of self-control is significant in boys, but not in girls.

The results provide a way to explain the mechanism of family economic stress affecting risk-taking behavior, and provide an important practical basis for intervening teenagers' risk-taking behavior.
