Friendship Development and Intergroup Attitudes: The Role of Interpersonal and Intergroup Friendship Processes

Although there is a growing body of work concerning cross‐group friendship and intergroup attitudes, this work typically focuses on a limited number of interpersonal processes among established friendships. In addition, little is known about the role of group‐related processes within such friendships. Two studies were conducted to address this gap. Results from a retrospective online survey and a longitudinal study reveal that both interpersonal friendship processes (e.g., intimacy, affection, trust, self‐disclosure) and intergroup friendship processes (e.g., belief that outgroup friend respects one's own group, spending time with outgroup friend's family members and friends) are associated with positive intergroup attitudes. Specifically, the current findings suggest that interpersonal friendship processes are vital to fostering positive attitudes for the outgroup early in the relationship, but that intergroup friendship processes become more strongly linked to attitudes once the relationship progresses. Results may inform interventions designed to promote positive interactions across “real‐world” group boundaries.
