本研究对233名三到六年级儿童进行三次间隔一周的问卷测量，通过建立潜变量增长模型，考察父母间冲突和亲子关系的发展趋势和关系，并探究儿童年龄、父母教养方式、家庭社会经济地位、孤独感和抑郁的影响。结果发现：（1）父母间冲突、亲子关系和抑郁在三周内较为稳定，孤独感上升趋势接近明显。父母间冲突、孤独感和抑郁的初始水平和发展速度存在显著个体差异。亲子关系的初始水平个体差异显著。儿童感知的父母间冲突、亲子关系、孤独感和抑郁的初始水平和发展速度无关；（2）父母接纳和控制对父母间冲突和亲子关系的初始水平有显著影响，并且父母控制显著影响父母间冲突的发展速度。父母对孩子越接纳，父母间冲突初始水平越低。父母对孩子越控制，父母间冲突初始水平越高，对亲子关系初始水平影响则相反。当父母对孩子比较控制时，父母间冲突的增长速率越低；（3）儿童年龄和家庭社会经济地位影响亲子关系的初始水平。儿童年龄越大，亲子关系的初始水平越低。家庭社会经济地位越高，亲子关系初始水平越高；（4）孤独感和抑郁影响父母间冲突和亲子关系。在某个时间点上，儿童孤独感越高，父母间冲突的水平越高，亲子关系的水平越低。抑郁在第三次测量中对父母间冲突的影响显著，抑郁水平越高，父母间冲突的水平越高。抑郁在第一次、第二次测量中对亲子关系的影响显著，儿童越抑郁，亲子关系的水平越低；（5）父母间冲突的初始水平显著负向影响亲子关系的初始水平，亲子关系的发展速度显著负向预测父母间冲突的发展速度。初始测量时感知父母间冲突更高的儿童，其亲子关系初始水平较低。儿童在三次测量期间感知亲子关系下降速度较快，感知的父母间冲突上升速度也较快。研究结果对家庭系统、父母教养和内化问题干预具有理论和现实意义。

The study measured 233 children in grades three to six one week apart by three times, and the development trend and relationship between interparental conflict and parent-child relationship were examined by establishing the latent variable growth model, and explored the effects of children's age, parenting style, family socioeconomic status, loneliness, and depression. The results showed that: (1) interparental conflict, parent-child relationship and depression were relatively stable within three weeks, and the increasing trend of loneliness was close to obvious. There were significant individual differences in the initial level and rate of development of interparental conflict, loneliness, and depression. Individual differences in the initial level of parent-child relationship were significant. The correlation between the initial level and the rate of development of perceived interparental conflict, parent-child relationship, loneliness, and depression were not significant; (2) parental acceptance and control had significant impacts on the initial level of interparental conflict and parent-child relationship, and parental control significantly affected the development rate of interparental conflict. The more accepting parents were to their children, the lower the initial level of interparental conflict. The more controlling parents had over their children, the higher the initial level of interparental conflict. And the opposite is the effect on the initial level of parent-child relationship. When parents were more in control of their children, the rate of growth of interparental conflict was lower; (3) children's age and family socioeconomic status affected the initial level of parent-child relationship. The older the child, the lower the initial level of parent-child relationship. The higher the socioeconomic status of the family, the higher the initial level of parent-child relationship; (4) loneliness and depression affected interparental conflict and parent-child relationship. At some point in time, the higher the child's loneliness, the higher the level of interparental conflict and the lower the level of parent-child relationship. Depression had a significant effect on interparental conflict in the third measurement, and the more depressed the child, the higher the level of interparental conflict. Depression had a significant effect on parent-child relationship in the first and second measurements, and the more depressed the child, the lower the level of parent-child relationship; (5) The initial level of interparental conflict significantly negatively affected the initial level of parent-child relationship. The development rate of parent-child relationship significantly negatively predicted the development rate of interparental conflict. Children who perceived higher interparental conflict on initial measurement had the lower initial level of parent-child relationship. Children who experienced a faster decline in parent-child relationship had a faster increase in perceived interparental conflict during the three measurements. The results have theoretical and practical implications for family system, parenting and intervention of internalization.
