Communication privacy management (CPM), originally known as communication boundary management, is a theory about how people make decisions about revealing and concealing private information. CPM theory suggests that individuals maintain and coordinate privacy boundaries (the limits of what they are willing to share) with various communication partners depending on the perceived benefits and costs of information disclosure. It was first developed by Sandra Petronio in 1991. Petronio uses a boundary metaphor to explain the privacy management process. Privacy boundaries draw divisions between private information and public information. This theory argues that when people disclose private information, they depend on a rule-based management system to control the level of accessibility. An individual’s privacy boundary governs his or her self-disclosures. Once a disclosure is made, the negotiation of privacy rules between the two parties is required. A distressing sense of “boundary turbulence” can arise when clashing expectations for privacy management are identified. Having the mental image of protective boundaries is central to understanding the five core principles of Petronio’s CPM: (1) People believe they own and have a right to control their private information. (2) People control their private information through the use of personal privacy rules. (3) When others are told or given access to a person’s private information, they become co-owners of that information. (4) Co-owners of private information need to negotiate mutually agreeable privacy rules about telling others. (5) When co-owners of private information don’t effectively negotiate and follow mutually held privacy rules, boundary turbulence is the likely result. == Background == Petronio’s communication privacy management (CPM) theory is built on Altman’s dialectical conception of privacy as a process of opening and closing a boundary to others. Altman and Taylor’s Social Penetration Theory focused on self-disclosure as the primary way to develop close relationships. However, openness is only part of the story. We also have a desire for privacy. When Petronio first developed this theory in 1991, it was called Communication Boundary Management. In 2002 she renamed it as Communication Privacy Management, underscoring private disclosure is the main thrust of the theory. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Communication privacy management theory」の詳細全文を読む スポンサード リンク
