communication. It first analyses how people choose certain communication environments on their smartphones, how they manipulate them, and how these external factors affect self-disclosure within these environments. It then details a multi-method study conducted to test the derived assumptions and discusses the obtained results. Part III reflects on the overall implications of the theory, summarizes the major findings and lastly considers possible extensions and perspectives on future research. Intended mainly for researchers in privacy and communication studies, the book offers privacy scholars a systematic review of both classic and contemporary theories of privacy and self-disclosure. At the same time, communication scholars benefit from an additional methodological discussion of the mobile experience sampling method, which provides an invaluable approach to measuring situational communication processes.
