Objective: To explore the mediating role of parent-child conflict in psychological reactance and problematic mobile phone use and the moderating role of restrictive mediation. Methods: The study recruited 994 adolescents using the Psychological Reactance Scale, Parent-Child Conflict Scale, Mobile Phone Problem Use Scale and Restrictive Mediation Scale. Results: ① The psychological reactance, problematic mobile phone use and parent-child conflict were significantly related. ② Parent-child conflict mediated the relationship between psychological reactance and problematic mobile phone use. ③ Restrictive mediation played a moderating role. As compared to the adolescents with a low level of restrictive mediation, the positive link between psychological reactance and parent-child conflict was stronger, while the positive relationship between parent-child conflict and problematic mobile phone use was weaker anion adolescents with a high level of restrictive mediation. Conclusion: Parent-child conflict and restrictive mediation play the moderated mediating roles in the relationship between psychological reactance and problematic mobile phone use.

目的：探讨亲子冲突在心理逆反和问题性手机使用关系中所起的中介作用和限制干预的调节作用。方法：采用心理逆反量表、亲子冲突量表、问题性手机使用量表和限制干预量表对994名青少年进行问卷调查。结果：(1)心理逆反、问题性手机使用和亲子冲突均显著正相关。(2)心理逆反可以通过亲子冲突的中介作用间接地影响问题性手机使用。(3)限制干预起调节作用，高水平的限制干预增强了心理逆反对亲子冲突的正向作用，弱化了亲子冲突对问题性手机使用的正向作用。结论：亲子冲突和限制干预在心理逆反对问题性手机使用的关系中起到有调节的中介作用。
