This research reviews the constructs and measurements of guanxi and concludes that colleague guanxi is appropriately conceptualized as a multidimensional construct that describes Chinese colleague relationships. The development of a colleague guanxi scale with four dimensions is described. Two studies test the convergent, discriminant, and nomological validity of the guanxi scale. In validation tests guanxi intensity increases with cognition features (subjective fit and cognitive trust) and results in a positive affect (affective trust). Contributions of the colleague guanxi scale are offered.
