Erina MacGeorge (Ph.D., 1999, University of Illinois) is Associate Professor of Communication Arts and Sciences at Pennsylvania State University. Her research interests span interpersonal and health communication, with a focus on social support and social influence. With her students, she developed advice response theory, which explains advice outcomes for recipients as a function of message, advisor, situation, and recipient characteristics. Her work has been published in outlets that include Communication Research, Journal of Health Communication, Human Communication Research, Communication Monographs, and the Sage Handbook of Interpersonal Communication. Recent studies examine advice between doctors and parents about childhood antibiotic use and breast cancer patients making surgical decisions with input from their social networks, as well as advice between college student friends coping with everyday problems. She is currently editing the Oxford Handbook of Advice, and is co-author of the textbook Inter-Act (14th ed.).
