原生家庭对夫妻婚后的干涉已经成为我国相当普遍的社会现象，并且原生家庭干涉对婚姻稳定性可能具有消极的影响作用，但是这其中的影响机制还尚不清楚，随着婚龄的增加，原生家庭干涉在减弱，那不同婚龄段原生家庭干涉对婚姻稳定性的影响机制是否一致也需要探讨。因此，探讨不同婚龄段的原生家庭干涉对婚姻稳定性的影响机制具有非常重要的临床意义，有助于设计针对特定婚龄段的夫妻因原生家庭干涉议题影响婚姻稳定性的干预方案。本研究所用数据来源于国家自然科学基金“夫妻互动与婚姻质量和稳定性的关系”项目，共招募到 313对有效夫妻被试：123 对新婚夫妻，91对婴幼儿父母，99对学龄前儿童父母，来源于北京、天津两地。夫妻双方独立填写人口学变量问卷、原生家庭干涉问卷、婚姻质量问卷和婚姻稳定性问卷，以探讨不同婚龄段的原生家庭干涉的现状及特点，不同方面的原生家庭干涉(家庭生活干涉和个人生活干涉)对婚姻稳定性的影响和婚姻质量在其中的中介作用，以及不同婚龄段在影响作用和机制方面的一致性问题。研究主要结论如下： （1）在婴幼儿父母和学龄前儿童父母中，夫妻感知到的家庭生活干涉显著高于个人生活干涉。新婚夫妻中，只有妻子感知到的家庭生活干涉显著高于个人生活干涉。 （2）在原生家庭干涉总分方面，对于丈夫来说，三个婚龄段没有显著差异；对于妻子来说，婴幼儿父母阶段的妻子感知到的原生家庭干涉显著高于另外两个婚龄段。此外，除新婚夫妻外，婴幼儿父母和学龄前儿童父母中都是妻子感知到的原生家庭干涉显著高于丈夫。 （3）丈夫感知到的家庭生活干涉负向预测自身的婚姻稳定性，妻子感知到的家庭生活干涉负向预测自身和配偶的婚姻稳定性。新婚和婴幼儿父母阶段的妻子感知到的家庭生活干涉负向预测自身和配偶的婚姻稳定性；婴幼儿父母阶段的丈夫感知到的家庭生活干涉负向预测自身的婚姻稳定性；学龄前儿童阶段的妻子感知到的个人生活干涉负向预测配偶的婚姻稳定性。 （4）丈夫的婚姻质量在丈夫感知到的原生家庭对于家庭生活方面的干涉和自身或配偶的婚姻稳定性之间起了完全中介作用；丈夫或妻子的婚姻质量在妻子感知到的原生家庭对于家庭生活方面的干涉和丈夫的婚姻稳定性之间起了完全中介作用；妻子或丈夫的婚姻质量在妻子感知到的原生家庭对于家庭生活方面的干涉和自身的婚姻稳定性之间起了部分中介作用。进一步比较三个婚龄段的模型，学龄前儿童父母中无显著路径，新婚夫妻和婴幼儿父母两个婚龄段的差异是：婴幼儿父母的丈夫感知到的原生家庭对于家庭生活方面的干涉通过丈夫的婚姻质量影响了丈夫的婚姻稳定性；在新婚夫妻中，该间接效应不显著。婴幼儿父母的妻子感知到的原生家庭对于家庭生活方面的干涉通过妻子的婚姻质量影响了妻子的婚姻稳定性；在新婚夫妻中，该间接效应不显著。

The interference of the original family to the husband and wife after marriage has become a fairly common social phenomenon in China, and the interference of the original family may have a negative impact on the stability of marriage. However, the mechanism of influence is still unclear. With the increase of the age of marriage, the interference of the original family is weakening. And it is necessary to explore whether the mechanism of the influence of the original family intervention on the stability of marriage in different marriage ages is consistent. Therefore, it is of great clinical significance to explore the influence of original family interference on the stability of marriage in different marriage ages, and it is helpful to design an intervention program for couples of certain ages of marriage that affect the stability of marriage due to the issue of the interference from family of origin. The data used in this study came from the National Natural Science Foundation of China (NSFC) project “The relationship between the marital interaction with marital quality and stability”, which was hosted by Professor Fang Xiaoyi. A total of 313 valid couples were recruited:123 newlywed couples, 91 parents of babies, 99 parents of preschool children, mainly from Beijing and Tianjin. Both spouses filled out independently: demographic variables questionnaire, family of origin interference questionnaire, Quality of Marriage Index and Marital Instability Scale-Short Form. The purpose of this study is to describe the status and characteristics of original family interference in different marriage ages. The effects of different aspects of original family interference (family life interference and individual life interference) on marital stability and the mediating role of marital quality, as well as the consistency of impact and mechanism in different marriage ages. The main findings of the study are as follows: (1) Among the parents of infants and the parents of preschool children, the family life interference perceived by the husband and wife is significantly higher than the interference of individual life. Among newlywed couples, only the family life interference perceived by the wife is significantly higher than the interference of individual life. (2) In terms of the total score of original family interference, for husbands, there is no significant difference among the three marriage age groups; for wives, the wives at the stage of infant parents perceive significantly higher interference from the original family than the other two marriage age groups. In addition, except for newlywed couples, both the infant parents and the parents of preschool children perceive significantly higher levels of original family interference than their husbands. (3) Family life interference perceived by husbands negatively predicts their marital stability, while that perceived by wives negatively predicts their marital stability and spouse's marital stability. Wives' perceived interference in family life at the stage of newlyweds and infants' parents negatively predicted marital stability of themselves and spouses; husbands' perceived interference in family life at the stage of infants' parents negatively predicted marital stability of themselves; wives' perceived interference in individual life at the stage of preschool children negatively predicted marital stability of spouses. (4) The marital quality of the husband plays a completely mediating role between the interference of the original family perceived by the husband in family life and the marital stability of himself or his spouse; the marital quality of the husband or wife plays a completely mediating role between the interference of the original family perceived by the wife in family life and the marital stability of the husband; the marital quality of the wife or husband plays a completely mediating role in the interference of the original family perceived by the wife in family life; and the quality of the wife’s or husband’s marriage has a partial mediation between the wife’s perception of the original family’s interference in family life and the stability of her own marriage. Further comparing the models of the three marriage ages, there is no significant path in the parents of preschool children. The difference between the two marriage ages of newly married couples and infant parents is that the interference of the original family perceived by the husband of the parents of babies affects the marital stability of the husband through the marital quality of the husband; in the newlyweds, the indirect effect is not significant. The interference of the original family to family life perceived by the wives of infant parents affects the marital stability of the wives through their marital quality, but the indirect effect is not significant in the newlywed couples.
