Basic Suppositions of CPM
As we have noted, CPM is concerned with explaining people's negotiation processes around disclosing private information. Our first task, then, is defining private information. Some researchers have stated that "what makes things private is in large part their importance to our conceptions of ourselves and to our relationships with others". Petronio commented that people define private information as information about things that matter deeply to them. Thus, the process of communicating private information in relationships with others becomes private disclosures. As we have stated previously, CPM focuses on private disclosures rather than self-disclosures.
The emphasis away from self-disclosure makes a distinction between CPM's definition of disclosure and that of traditional research on openness.CPM views the definition differently in three ways. First, private disclosure puts more emphasis on the personal content of the disclosure than does traditional self-disclosure literature. In doing this, CPM gives more credence to the substance of disclosures, or that which is considered private. Additionally,CPM examines how people disclose through a rule-based system. Finally, CPM does not consider that disclosures are only about the self. Disclosures are a communicative process. As Petronio observes, "to fully understand the depth and breadth of a disclosure, CPM does not restrict the process to only the self, but extends it to embrace multiple levels of disclosure including self and group. Consequently, CPM theory offers a privacy management system that identifies ways privacy boundaries are coordinated between and among individuals".
Communication Privacy Management Theory accomplishes this goal by proposing five basic suppositions: private information, private boundaries,control and ownership, rule-based management system, and management dialectics （see Figure 12.1）. We
