What is interpersonal communication? Is it limited to interaction between two people? Does it only involve personal relationships? Does it go beyond face-to-face interactions? Can it take place in a variety of contexts, such as the workplace, a health practitioner's office, or online? This fully revised Third Edition of the Handbook of Interpersonal Communication addresses these and other fundamental yet pivotal questions, offering graduate students and faculty interested in the study of interpersonal communication an important, state-of-the-art reference work. Providing a complete course of study, the Handbook includes the following units: Basic Issues and Approaches; Perspectives on Inquiry; Fundamental Units; Processes and Functions; and Interpersonal Contexts.
