For years, Dr. Danielle Arigo from Rowan University (NJ) has been studying the social influences on health and health behavior (such as eating and exercise behavior), chronic illness self-management, women’s health, and body image/eating disorders. She has been seeking to optimize eHealth and mHealth programs by incorporating beneficial social processes via online networking. With a great honor, mHealth is pleased to have this opportunity to interview Dr. Arigo, who will share with us the merits and limitations of the use of health behavior change apps, the current and future development of mobile technology in health psychology and behavioral medicine, the research she is currently working on and the challenges encountered in these research projects.
