Abstract: Since conflict studies became its own independent field, it has developed rapidly. Some argue conflict researchers must demonstrate that while conflict occurs at different social levels (e.g., inter-personal to international), there must be sufficient common attributes to justify its existence as an independent field. This justification requires formal theory based on a multi-disciplinary approach. Since its introduction in 1964, the substantive Dual Concerns Model (DCM) and subsequent iterations, have provided the basis for instruments used to research conflict management, behavior, mode, and style outside the narrow scope of its original sample group of Caucasian male managers within a large American industrial plant. Instruments based on the DCM were used to represent conflict behavior within, between, and across cultures. An emic theory was expanded to etic theory and used in place of formal theory. Therefore, this theoretical dissertation fills this void and develops formal (etic) theory. This researcher used comparative analysis to examine 187 quantitative studies from a variety of disciplines, with a cumulative sample size from these studies of 63,619 individuals. These studies examined conflict resolution behavior individually or with 274 other variables to provide the framework for developing a formal theory. The finding of this research is the development of the Pierre-Louis Conflict Continuum Model (PCCM), which examines behavior through the dimensions of cultural values, as represented by individualism and collectivism, and legitimacy of power and ideology. This research contributes a new theoretical paradigm to the field of conflict studies.
