Advice is a ubiquitous and consequential form of communication in both personal and professional interactions. The exchange of advice has varied outcomes for recipients, advisors, and social networks. The outcomes of advice for recipients are influenced by message content, message style and interactional sequence, characteristics of the advisor, and recipient perceptions, emotions, and traits. Advisors’ cognitive processes and traits also influence the effectiveness of advice. Advice response theory and the integrated model of advice provide theoretical frameworks for understanding advice outcomes.
