Assessing the interpersonal transaction cycle: convergence of action and reaction interpersonal circumplex measures.

Contemporary interpersonal theory uses 2 models to represent the process and content of interpersonal transactions. The interpersonal transaction cycle is a dynamic model demonstrating the interaction between the overt behaviors and the covert intrapsychic experiences of 2 interacting individuals in action-reaction event chains. The interpersonal circle is a static model codifying individual differences across various interpersonal content domains (e.g., traits, acts, problems, impacts). The present study used 150 pairs of undergraduates to demonstrate cross-observer structural convergence of 2 separate interpersonal circumplex inventories measuring the "action" and "reaction" components of the transaction cycle, providing evidence that both components of the cycle can be captured by existing circumplex measures, and allowing researchers to proceed on to more comprehensive tests of interpersonal theory.
