目的 探讨白血病患儿父母二元应对在负性情绪和家庭功能间的主客体互倚中介关系。 方法 便利抽样法选取白血病患儿父母221对，采用二元应对量表（dyadic coping inventory，DCI）、医院焦虑抑郁量表、中文版家庭亲密度和适应性量表(family adapt ability and cohesion evaluation scales，FACES)对其进行调查，通过主客体互倚中介模型分析三者之间的关系。 结果 白血病患儿父母焦虑得分均对自身DCI得分存在主体效应（β=-0.50、-0.20），患儿母亲焦虑对父亲DCI得分存在客体效应（β=-0.35），患儿父母的DCI得分均对自身及配偶FACES得分存在主客体效应（β=0.37、0.33、0.17、0.11）。白血病患儿父母DCI得分在母亲焦虑与FACES得分间的中介效应为61%和47%；在父亲焦虑得分与FACES得分间的中介效应为94%和72%。 结论 患儿父母家庭功能不仅受自身影响，也受伴侣的影响，需关注患儿父母二元交互水平对焦虑和家庭功能的影响，以父母为整体进行干预，提高家庭功能稳定性。

Objective To explore the relationship among negative emotions,family functioning and dyadic coping in parents of children with leukemia.Methods 221 pairs of such parents were conveniently selected and surveyed using DCI, hospital anxiety and depression scale,and FACES.The relationships among the three were analyzed through the actor-partner interdependence mediation model(APIMeM).Results Results showed that there was a subject effect of both parents’ anxiety scores on their own DCI scores for children with leukemia (β=-0.50,-0.20),an object effect of the child’s mother’s anxiety on the father’s DCI scores (β=-0.35),and a subject-object effect of the child’s parent’s DCI scores on both their own and their spouse’s FACES scores (β=0.37,0.33,0.17,0.11).The mediating effect of the DCI scores of these parents between the mother’s anxiety score and the FACES score was 61% and 47%;the mediating effect between the father’s anxiety score and the FACES score should be 94% and 72%.Conclusions Parent’s family functioning is not only influenced by themselves but also by their partners,and attention needs to be paid to the effect of the dichotomous interaction level of them on anxiety and family functioning.Intervention with these parents as a whole should be conducted to improve the stability of the family.
