Objective To explore the specific impact of work-family conflict on young mothers' emotions , and to provide references for improving young mothers' mental health. Methods In March 2020，a cluster random sampling method was adopted to select 117 young mothers aged 3 to 45 in Beijing and Xian for a continuous 5-day diary method questionnaire survey; multiple regression analysis was used to detect the predictive effect. Results The length of working out hours of young mothers had a significant negative predictive effect on the three dimensions of mother's emotions: energy (β=-0.140，P<0.01)，valence= (β=0. 093，P<0.01) and calmness ( β=-0.096，P<0.01).While after subtracting the influence of the children's schoolwork hours，the negative predictive effect of the length of working out hours on the three-dimensions of mother's emotions: energy (β=-0.133, P<0.05)，valence (β=-0.01, P<0.05)and calmness (β=-0.094, P>0.05) are all weakened. Conclusion The time conflict brought about by the dual roles of work and family undertaken by young mothers will consume mother's energy, make mothers feel more negative emotional experience，and become more nervous.

摘要： 目的 探索工作家庭冲突对小学生母亲情绪的具体影响,为提升小学生母亲的心理健康提供参考.方法 2020年3月采用整群随机抽样的方法,抽取北京、西安的117名年龄位于35至45岁的小学生母亲进行连续为期5天的日记法问卷调查;采用多元回归分析进行预测效应检测.结果 小学生母亲的外出工作时长对母亲情绪的三个维度精力唤醒(β=-0.140,P＜0.01)、效价(β=-0.093,P＜0.01)和平静(β=-0.096,P＜0.01)有显著负向预测作用.消减掉孩子课业时长的影响之后,外出工作时长对小学生母亲情绪的三维度精力唤醒(β3=-0.133,P＜0.05)、效价(β=-0.101,P＜0.05)和平静(β=-0.094,P＞0.05)的负向预测作用均减弱.结论 小学生母亲所承担的工作和家庭双角色带来的时间冲突会消耗母亲的精力,令母亲感受到更多的负面情绪体验,也更紧张.
