童年环境不可预测性对大学生利他行为的影响:一个有调节的中介模型

Childhood Unpredictability on Altruistic Behavior in College Students:Moderated Mediating Effect

目的:考察童年环境不可预测性与大学生利他行为之间的关系,并探讨冷酷无情特质的中介作用以及童年环境严酷性的调节作用。方法:采用童年环境不可预测性量表、童年环境严酷性量表、冷酷无情特质量表、大学生利他行为问卷,对950名大学生进行调查。结果:童年环境不可预测性显著负向预测大学生利他行为;冷酷无情特质在童年环境不可预测性与大学生利他行为之间起中介作用;童年环境严酷性能显著调节中介模型的前半段与直接路径,即在高童年环境严酷性水平下,童年环境不可预测性对冷酷无情特质和大学生利他行为的预测作用增强。结论:童年环境不可预测性通过冷酷无情特质影响大学生利他行为,且童年环境严酷性水平越高的个体,其童年环境不可预测性对冷酷无情特质和利他行为的预测作用越强。

Objective:To explore the relationship between childhood unpredictability and altruistic behavior,and the moderated mediation effects of callous-unemotional traits and childhood harshness.Methods:In total 950 college students were recruited in the study to complete childhood unpredictability scale,childhood harshness scale,callous-unemotional traits scale and altruistic behavior scale.Results:Childhood unpredictability had a significant negative prediction for altruistic behavior of college students;Callous-unemotional traits played a partial mediating role between childhood unpredictability and altruistic behavior;Childhood harshness moderated the mediating effect of callous-unemotional traits.Specifically,the significant effect of childhood unpredictability on callous-unemotional traits and altruistic behavior was stronger when the level of childhood harshness was higher.Conclusion:Childhood unpredictability affects altruistic behavior through callous-unemotional traits,and the effect of childhood unpredictability on callous-unemotional traits and altruistic behavior is much stronger among college students with higher childhood harshness.
