Objective: To explore the influence of paternal overprotection on achievement motivation of high school students and the mediating mechanism of autonomy and grit. Methods: Total 939 high school students were investigated by achievements motive scale, parental bonding instrument, basic psychological needs scales and short grit scale Results: Correlation analyses showed that paternal overprotection was negatively correlated with high school students’ autonomy, grit and achievement motivation （r=-0.19 ,-0.15 ,-0.16 , P＜0.01); High school students' autonomy was positively correlated with grit and achievement motivation(r=0.47,0.48,P＜ 0.01); High school students' grit was positively correlated with achievement motivation(r -0.51，P ＜0.01)Mediation effects analyses indicated effects on achievement motivation through the mediating effect of autonomy and grit，respectively, as well as the chain mediating effect of autonomy and grit. Conclusion: High school students’ autonomy and grit are the mediating mechanisms in the association between paternal overprotection and achievement motivation.

目的:探讨父亲过度保护对高中生成就动机的影响,以及自主需要和坚毅力在其中的中介机制.方法:采用成就动机量表、父母教养方式问卷、基本心理需求量表、简式坚毅问卷对939名高中生进行调查.结果:相关分析显示,父亲过度保护与高中生的自主需要、坚毅力、成就动机均显著负相关(r=-0.19,-0.15,-0.16;P<0.01);高中生自主需要与其坚毅力、成就动机显著正相关(r=0.47,0.48;P<0.01);高中生的坚毅力与成就动机显著正相关(r=0.51,P<0.01).中介效应分析显示,父亲过度保护不能直接预测高中生成就动机,但分别通过高中生的自主需要及坚毅力的中介作用,以及这两者形成的链式中介效应产生的间接效应发挥影响.结论:高中生自主需要和坚毅力是父亲过度保护对高中生成就动机影响的中介机制.
