The positive group affect spiral: a dynamic model of the emergence of positive affective similarity in work groups

This conceptual paper seeks to clarify the process of the emergence of positive collective affect. Specifically, it develops a dynamic model of the emergence of positive affective similarity in work groups. It is suggested that positive group affective similarity and within-group relationship quality are reciprocally interrelated in the form of a self-reinforcing spiral, which is driven by mechanisms of affective sharing and affective similarity-attraction between group members. We label this spiraling relationship 'Positive Group Affect Spiral.' This spiral is proposed to continuously strengthen both the similarity of group members' positive affect and the quality of their interpersonal relationships in a dynamic process. Further, we embed the Positive Group Affect Spiral into a framework of contextual factors that may diminish or strengthen its functioning, considering the potential impacts of charismatic leadership, individuals' or subgroups' organizational cynicism, group and organizational emotion norms, and organizational identity.
