A Two-Year Longitudinal Study of Naturalistic Parent–Child-Originated and Sibling-Originated Polyadic Conflicts

Abstract:Naturalistic polyadic family conflicts (i.e., involving three or more members) were studied over a 2-year period by comparing disputes originating between siblings (sibling-originated) or a parent and child (parent–child-originated). Conflicts were coded for (a) origination, (b) topic, (c) resolution, and (d) power in 39 families with two children when both were 2 and 4 years old (T1) and again at 4 and 6 years of age (T2). Greater proportions of sibling-originated and parent–child-originated conflicts were observed at T1 and T2, respectively. In sibling-originated conflicts, time-related variations for ownership and controlling behaviors were apparent. Controlling behavior, ownership, and provocative behavior conflicts varied over time in parent–child-originated disputes. Submissions were most frequent in sibling-originated conflicts, whereas no resolutions and submissions were more common at Time 1 (T1) and Time 2 (T2) during parent–child-originated disputes, respectively. Time-related changes in various power moves were evident. This study contributes to the literature on the importance of the family in children’s social and cognitive development.
