The focus of the current study is whether, and why, female patients limit or alter their personal histories when discussing sensitive subject matter with their physician in birth control clinics. Fifty-six female patients (M = 21.6 years, SD = 3.05) completed anonymous questionnaires exploring their comfort with and ability to disclose personal histories in the immediately preceding interview with the physician. The present study used communication privacy management (CPM) as the theoretical lens through which to view the interaction. Approximately one-half of the sample (46%) reported limiting or altering information. Patients with a highly permeable privacy orientation, as evidenced by a history of open communication regarding sexual issues, were those who reported fully disclosing to their physicians. Of the physician characteristics considered to map onto patient privacy rules, the physician's gender, hurriedness, friendliness, use of a first-name introduction, and open-ended questions were significantly related to patients' reported ease in fully disclosing personal information (p < .05). This study presents a novel application of CPM and has implications for training medical students and for parent-child communication regarding sexual issues.
