Family-of-origin triangulation and marital stability: A multiple mediation model

Previous research on family triangulation has mainly focused on nuclear family triangulation. In this study we explored the effects of family-of-origin triangulation on marital stability in China, and the mediating roles of parenting sense of competence and coparenting. Participants were 1,144 Chinese parents aged 24 to 48 years, who completed surveys on family-of-origin triangulation, parenting sense of competence, coparenting, and marital stability. The results show that family-of-origin triangulation was negatively associated with marital stability. This relationship was mediated by coparenting, but the mediating effect of parenting sense of competence was nonsignificant. In addition, parenting sense of competence and coparenting sequentially mediated the relationship between family-of-origin triangulation and marital stability. Our findings highlight the risk of harm to marital stability from family-of-origin triangulation.
