Capitalization,a prevalent behavior in interpersonal communication,has garnered significant attention in the field of positive psychology.While early research predominantly explored capitalization within intimate relationships,recent studies have shifted focus to its interpersonal implications in the workplace.These investigations examine the antecedents and outcomes of capitalization from various perspectives.In order to get a full picture of capitalization,this paper provides a systematic review of capitalization,focusing on its definition and distinguishing it from related concepts.It then synthesizes current measures of capitalization and explores its antecedents,including individual characteristics,motivation,emotion,attitude,and cultural factors,as well as its effects on sharers,responders,and interpersonal relationships,while discussing relevant boundary conditions.Finally,the paper proposes a comprehensive theoretical model of capitalization and identifies potential avenues for future research,offering insights for further studies on capitalization in the workplace.
