To further refine the measurement of coparenting across family dynamics, this article presents data from 2 separately collected samples, the first consisting of 252 parents and the second consisting of 329 parents, analyzed as a pilot study of the Short-Form of the Coparenting Across Family Structures Scale (CoPAFS 27-Items). The purpose of the revised shortened tool is to further the design of an efficient and psychometrically strong tool to aid research and clinical practice with coparents. Our intent was to differentiate coparenting in intact, separated/divorced, and families where the parents were never romantically involved, between mothers and fathers, and between high- and low-income levels. This pilot test assessed psychometric properties (stability, reliability, and internal consistency) of the CoPAFS to determine whether the measure could be useful for evaluating the core dimensions of coparenting. Analyses reduced the 56-item CoPAFS scale developed from existing scales and literature to a 5-component scale of 27 items, including Respect, Trust, Valuing the other parent, Communication and Hostility. Implications for interventions and future research are briefly discussed.
