Triangulation is a central construct in family systems theory, theorized first by Bowen (1966) as a common feature of dysfunctional families adversely affecting child well-being. Triangulation refers parent-child relationship processes in which children are passively or actively involved in conflicts within the parental dyad and which, in the immediate situation, lessen the tension and anxiety between adults, thereby stabilizing the family. Typically, it can be divided into three patterns: cross-generational coalitions, scapegoating, and parentification. The cross-generational coalition refers to the children alliance with one parent and against the other one when a conflict occurs between parents; scapegoating normally involves the child who is pushed out and distance as a way of parents revolving or avoiding the conflict, such as focusing together on a difficult child away from their own issues; parentification refers to an earlier commitment to considerate parents’ or other families’ need, and take care of family responsibilities and roles. Empirical evidence indicates that greater adolescent exposure to triangulation is associated with less mature ego development, poorer peer relationships and parent-adolescent relationships, as well as increased internalizing and externalizing problems. However, there exists divergence in the viewpoint of possibility and types of girls or boys being more likely to be involved in parental conflicts. As to the possibility, some scholars claim that girls are more inclined to be caught because they are relationship-oriented and take more care for the interpersonal relationships, but others point out that the boys could be more vulnerable to be involved in parental conflict because of parents usually placing higher expectation for boys to take family responsibility and exposing boys to more conflict than girls, and the boys having much more difficulties in controlling and coping with the stress. As to the types of children being caught by parental conflicts, some studies found that girls were more likely to be caught by parental conflict as a coalition partner with a parent, and however the boys were more likely triangulated as a scapegoating, but others’ findings indicated that boys were more likely than girls to be victims of scapegoating though no gender difference in the cross-generational coalition emerged. There were also studies failed to discover any gender difference in parent-adolescents triangulation. The present study systematically and for the first time reviewed previous reports about gender differences in the triangulation, and found that the causes of the inconsistence of the results may be as follows: demographic variables, which are consisted of participants’ grade, the differences in the number, birth order and gender make-up of children in the family, family structure; the research method such as the method of survey and the specific indicators of triangulation; the change of the participants’ attitudes towards gender role. Future research should focus on localization study, detail the demographic variables, use multiple methods of survey and indicators of parent-child triangulation, improve the analysis method, and adopt a longitudinal design at the same time collecting the data about participants’ interrelationship orientation and attitudes towards gender role to further clarify the gender differences in parent-child triangulation.
