Most family-system research on triangulation processes has been undertaken in the West, with little known about this family dynamic in the East. The present cross-sectional study analysed 1,073 Chinese 3rd–12th-graders’ self-reported exposure to three kinds of triangulation—cross-generation coalition, scapegoating, and parentification—in relation to family and child factors and with respect to children’s school and social adjustment. Age-related analyses generally indicated that older children were less frequently exposed to all three dimensions of triangulation than younger ones. Children residing with only their parents experienced more scapegoating than those living in extended families; and boys were exposed to cross-generation coalition and scapegoating more than were girls. Higher levels of coalition and scapegoating exposure were related to poorer school adjustment and greater depression of children. Higher levels of parentification exposure, however, were associated with better school adjustment and social functioning. Findings are discussed in terms of theory and research on parent–child triangulation and cultural differences between East and West.
